COMBUSTION AND VENTILATION Today’s homes are built more energy effi- cient than ever. New materials, increased insulation, and new construction methods help reduce heat loss in homes. Home owners weather strip and caulk around windows and doors to keep the cold air out and the warm air in. During heating months, home owners want their homes as airtight as possible. While it is good to make your home energy efficient, your home needs to breathe. Fresh air must enter your home. All fuel-burning appliances need fresh air for proper com- bustion and ventilation. Exhaust fans, fireplaces, clothes dryers, and fuel burning appliances draw air from the house to operate. You must provide ad- equate fresh air for these appliances. This will insure proper venting of vented fuel- burning appliances. Confined and Unconfined Space The National Fuel Gas Code, ANS Z223.1 defines a confined space as a space whose volume is less than 50 cubic feet per 1,000 Btu per hour (4.8 m3 per kw) of the aggre- gate input rating of all appliances installed in that space and an unconfined space as a space whose volume is not less than 50 cubic feet per 1,000 Btu per hour (4.8 m3 per kw) of the aggregate input rating of all appliances installed in that space. Rooms communicating directly with the space in which the appliances are installed*, through openings not furnished with doors, are con- sidered a part of the unconfined space. This heater shall not be installed in a con- fined space or unusually tight construction unless provisions are provided for adequate combustion and ventilation air. * Adjoining rooms are communicating only if there are doorless passageways or ventila- tion grills between them. WARNING: This heater shall not be installed in a confined space or unusually tight construction unless provisions are provided for adequate combustion and ven- tilation air. Read the following in- structions to insure proper fresh air for this and other fuel-burning appliances in your home. PROVIDING ADEQUATE VENTILATION The following are excerpts from National Fuel Gas Code, NFPA 54/ANS Z223.1, Sec- tion 5.3, Air for Combustion and Ventilation. All spaces in homes fall into one of the three following ventilation classifications: 1. Unusually Tight Construction 2. Unconfined Space 3. Confined Space The information on pages 5 through 7 will help you classify your space and provide adequate ventilation. Unusually Tight Construction The air that leaks around doors and win- dows may provide enough fresh air for combustion and ventilation. However, in buildings of unusually tight construction, you must provide additional fresh air. Unusually tight construction is de- fined as construction where: a. walls and ceilings exposed to the outside atmosphere have a con- tinuous water vapor retarder with a rating of one perm (6x10-11 kg per pa-sec-m2) or less with open- ings gasketed or sealed and b. weather stripping has been added on openable windows and doors and c. caulking or sealants are applied to areas such as joints around window and door frames, be- tween sole plates and floors, be- tween wall-ceiling joints, be- tween wall panels, at penetra- tions for plumbing, electrical, and gas lines, and at other openings. If your home meets all of the three criteria above, you must provide additional fresh air. See Ventilation Air From Outdoors, page 7. If your home does not meet all of the three criteria above, proceed to Determining Fresh- Air Flow For Heater Location, page 6. Continued

® DETERMINING FRESH-AIR FLOW FOR HEATER LOCATION Determining if You Have a Confined or Unconfined Space Use this worksheet to determine if you have a confined or unconfined space. Space: Includes the room in which you will install heater plus any adjoining rooms with doorless passageways or ventilation grills between the rooms. 1. Determine the volume of the space (length x width x height). Length x Width x Height = ____________________ cu. ft. (volume of space) Example: Space size 20 ft. (length) x 16 ft. (width) x 8 ft. (ceiling height) = 2560 cu. ft. (volume of space) If additional ventilation to adjoining room is supplied with grills or openings, add the volume of these rooms to the total volume of the space. 2. Divide the space volume by 50 cubic feet to determine the maximum Btu/Hr the space can support. _____________________(volume of space) ÷ 50 cu. ft. = (Maximum Btu/Hr the space can support) Example: 2560 cu. ft. (volume of space) ÷ 50 cu. ft. = 51.2 or 51,200 (maximum Btu/Hr the space can support) 3. Add the Btu/Hr of all fuel burning appliances in the space. Vent-free heater ___________________Btu/Hr Gas water heater* ___________________Btu/Hr Gas furnace ___________________Btu/Hr Vented gas heater ___________________Btu/Hr Gas fireplace logs ___________________Btu/Hr Other gas appliances* + ___________________Btu/Hr Total = ___________________Btu/Hr * Do not include direct-vent gas appliances. Direct-vent draws combustion air from the outdoors and vents to the outdoors. 4. Compare the maximum Btu/Hr the space can support with the actual amount of Btu/Hr used. _________________ Btu/Hr (maximum the space can support) _________________ Btu/Hr (actual amount of Btu/Hr used) Example: 51,200 Btu/Hr (maximum the space can support) 60,000 Btu/Hr (actual amount of Btu/Hr used) The space in the above example is a confined space because the actual Btu/Hr used is more than the maximum Btu/Hr the space can support. You must provide additional fresh air. Your options are as follows: A. Rework worksheet, adding the space of an adjoining room. If the extra space provides an unconfined space, remove door to adjoin- ing room or add ventilation grills between rooms. See Ventilation Air From Inside Building, page 7. B. Vent room directly to the outdoors. See Ventilation Air From Outdoors, page 7. C. Install a lower Btu/Hr heater, if lower Btu/Hr size makes room unconfined. If the actual Btu/Hr used is less than the maximum Btu/Hr the space can support, the space is an unconfined space. You will need no additional fresh air ventilation. AIR FOR COMBUSTION AND VENTILATION Continued Example: Gas water heater 30,000 Btu/Hr Vent-free heater + 30,000 Btu/Hr Total = 60,000 Btu/Hr WARNING: If the area in which the heater may be operated is smaller than that defined as an unconfined space or if building is of unusually tight construction, provide adequate combustion and ventilation air by one of the methods described in the National Fuel Gas Code, ANS Z223.1, Section 5.3 or applicable local codes.

Building This fresh air would come from an adjoining unconfined space. When ventilating to an adjoining unconfined space, you must pro- vide two permanent openings: one within 12" of the ceiling and one within 12" of the floor on the wall connecting the two spaces (see options 1 and 2, Figure 8). You can also remove door into adjoining room (see op- tion 3, Figure 8). Follow the National Fuel Gas Code, NFPA 54/ANS Z223.1, Section 5.3, Air for Combustion and Ventilation for required size of ventilation grills or ducts. Figure 8 - Ventilation Air from Inside Building Figure 9 - Ventilation Air from Outdoors Or Remove Door into Adjoining Room, Option 3 Ventilation Grills Into Adjoining Room, Option 2 12" 12" Ventilation Grills into Adjoining Room, Option 1 Outlet Air Ventilated Attic Outlet Air Inlet Air Inlet Air Ventilated Crawl Space To Crawl Space To Attic WARNING: Rework work- sheet, adding the space of the adjoining unconfined space. The combined spaces must have enough fresh air to supply all appliances in both spaces. AIR FOR COMBUSTION AND VENTILATION Continued Ventilation Air From Outdoors Provide extra fresh air by using ventilation grills or ducts. You must provide two per- manent openings: one within 12" of the ceiling and one within 12" of the floor. Connect these items directly to the outdoors or spaces open to the outdoors. These spaces include attics and crawl spaces. Follow the National Fuel Gas Code, NFPA 54/ANS Z223.1, Section 5.3, Air for Combustion and Ventilation for required size of ventilation grills or ducts. IMPORTANT: Do not provide openings for inlet or outlet air into attic if attic has a thermostat-controlled power vent. Heated air entering the attic will activate the power vent.

® WARNING: Never install the heater • in a bedroom or a bathroom • in a recreational vehicle • where curtains, furniture, clothing, or other flammable objects are less than 36 inches from the front, top, or sides of the heater • as a fireplace insert • in high traffic areas • in windy or drafty areas IMPORTANT: Vent-free heaters add mois- ture to the air. Although this is beneficial, installing heater in rooms without enough ventilation air may cause mildew to form from too much moisture. See Fresh Air for Com- bustion and Ventilation, pages 5 through 7. 36" 5" FLOOR CEILING Minimum Minimum To Top Surface Of Carpeting, Tile Or Other Combustible Material 6" Minimum From Sides Of Heater Left Side Right Side INSTALLATION CHECK GAS TYPE Use only propane/LP gas.

® Installation must include an equipment shutoff valve, union, and plugged 1/8" NPT tap. Locate NPT tap within reach for test gauge hook up. NPT tap must be upstream from heater (see Figure 21). IMPORTANT: Install an equipment shutoff valve in an accessible location. The equip- ment shutoff valve is for turning on or shutting off the gas to the appliance. Apply pipe joint sealant lightly to male threads. This will prevent excess sealant from going into pipe. Excess sealant in pipe could result in clogged heater valves. Tee Joint Reducer Bushing to 1/8" NPT 1/8" NPT Plug Tap Test Gauge Connection * Tee Joint Pipe Nipple Cap Sediment Trap Figure 21 - Gas Connection * A CSA/AGA design-certified equipment shutoff valve with 1/8" NPT tap is an acceptable alternative to test gauge connection. Purchase the optional CSA/AGA design-certified equipment shutoff valve from your dealer. See Accessories, page 23. Pressure Regulator 3/8" NPT Pipe Nipple Ground Union Joint Heater Cabinet 3" Minimum Note: Burner bracket not shown for clarity Equipment Shutoff Valve * CONNECTING TO GAS SUPPLY Figure 20 - External Regulator with Vent Pointing Down CAUTION: Use pipe joint seal- ant that is resistant to liquid pe- troleum (LP) gas. Propane/LP Supply Tank Vent Pointing Down External Regulator From External Regulator (11" W.C. to 14" W.C. Pressure) The installer must supply an external regu- lator. The external regulator will reduce incoming gas pressure. You must reduce incoming gas pressure to between 11 and 14 inches of water. If you do not reduce incom- ing gas pressure, heater regulator damage could occur. Install external regulator with the vent pointing down as shown in Figure 20. Pointing the vent down protects it from freezing rain or sleet. INSTALLATION Continued CAUTION: Use only new, black iron or steel pipe. Inter- nally-tinned copper tubing may be used in certain areas. Check your local codes. Use pipe of 1/2" or greater diameter to allow proper gas volume to heater. If pipe is too small, undue loss of pressure will occur. We recommend that you install sediment trap in supply line as shown in Figure 21. Locate sediment trap where it is within reach for cleaning. Install in piping system between fuel supply and heater. Locate sedi- ment trap where trapped matter is not likely to freeze. A sediment trap traps moisture and contaminants. This keeps them from going into heater controls. If sediment trap is not installed or is installed wrong, heater may not run properly. IMPORTANT: Hold pressure regulator with wrench when connecting it to gas pip- ing and/or fittings. WARNING: This appliance re- quires a 3/8" NPT (National Pipe Thread) inlet connection to the pressure regulator. WARNING: A qualified service person must connect heater to gas supply. Follow all local codes. WARNING: Never connect heater to private (non-utility) gas wells. This gas is commonly known as wellhead gas.

Turn control knob counterclockwise C-clockwise to the PILOT position. Press in control knob for five (5) seconds (see Figure 24). Note: You may be running this heater for the first time after hook- ing up to gas supply. If so, the con- trol knob may need to be pressed in for 30 seconds. This will allow air to bleed from the gas system. 6. With control knob pressed in, push down and release ignitor button. This will light pilot. The pilot is at- tached to the front of burner. If needed, keep pressing ignitor but- ton until pilot lights. Note: If pilot does not stay lit, refer to Troubleshooting, pages 16 through 18. Also contact a qualified service person or gas supplier for repairs. Until repairs are made, light pilot with match. To light pilot with match, see Manual Lighting Procedure, page 15. Pilot Burner Thermocouple Figure 25 - Pilot Ignitor Electrode CAUTION: Do not try to adjust heating levels by using the equip- ment shutoff valve. TO TURN OFF GAS TO APPLIANCE Shutting Off Heater 1. Turn control knob clockwise to the OFF position. 2. Turn off all electric power to the ap- pliance if service is to be performed. Shutting Off Burner Only (pilot stays lit) Turn control knob clockwise to the PILOT position. A. This appliance has a pilot which must be lighted by hand. When lighting the pilot, follow these instructions exactly. B. BEFORE LIGHTING smell all around the appliance area for gas. Be sure to smell next to the floor because some gas is heavier than air and will settle on the floor. WHAT TO DO IF YOU SMELL GAS • Do not try to light any appliance. • Do not touch any electric switch; do not use any phone in your building. • Immediately call your gas supplier from a neighbor’s phone. Follow the gas supplier’s instructions. • If you cannot reach your gas sup- plier, call the fire department. C. Use only your hand to push in or turn the gas control knob. Never use tools. If the knob will not push in or turn by hand, don’t try to repair it, call a qualified service technician or gas supplier. Force or attempted repair may result in a fire or explosion. D. Do not use this appliance if any part has been under water. Immediately call a qualified service technician to inspect the appliance and to replace any part of the control system and any gas control which has been un- der water. WARNING: If you do not fol- low these instructions exactly, a fire or explosion may result caus- ing property damage, personal injury or loss of life. 7. Keep control knob pressed in for 30 seconds after lighting pilot. After 30 seconds, release control knob. • If control knob does not pop up when released, contact a quali- fied service person or gas sup- plier for repairs. Note: If pilot goes out, repeat steps 3 through 7. This heater has a safety interlock system. Wait one (1) minute before lighting pilot again. 8. Turn control knob counterclockwise C-clockwise to desired heating level. The main burner should light. Set control knob to any heat level between HI and LO.

heater differs from standard thermostats. Standard thermostats simply turn on and off the burner. The thermostat used on this heater senses the room temperature. The thermostat adjusts the amount of gas flow to the burner. This increases or de- creases the burner flame height. At times the room may exceed the set temperature. If so, the burner will shut off. The burner will cycle back on when room temperature drops below the set temperature. The control knob can be set to any heat level between HI and LO. Note: The thermostat sensing bulb mea- sures the temperature of air near the heater cabinet. This may not always agree with room temperature (depending on housing construction, installation loca- tion, room size, open air temperatures, etc.). Frequent use of your heater will let you determine your own comfort levels. MANUAL LIGHTING PROCEDURE 1. Remove front panel (see Figure 2, page 3). 2. Follow steps 1 through 5 under Light- ing Instructions, page 14. 3. With control knob pressed in, strike match. Hold match to pilot until pi- lot lights. 4. Keep control knob pressed in for 30 seconds after lighting pilot. After 30 seconds, release control knob. Now follow step 8 under Lighting Instruc- tions, page 14. 5. Replace front panel.

PILOT FLAME PATTERN Figure 26 shows a correct pilot flame pattern. Figure 27 shows an incorrect pilot flame pattern. The incorrect pilot flame is not touch- ing the thermocouple. This will cause the thermocouple to cool. When the thermo- couple cools, the heater will shut down. If pilot flame pattern is incorrect, as shown in Figure 27 • turn heater off (see To Turn Off Gas to Appliance, page 14) • see Troubleshooting, pages 16 through 18 BURNER FLAME PATTERN Figure 28 shows a correct burner flame pattern. Figure 29 shows an incorrect burner flame pattern. The incorrect burner flame pattern shows yellow tipping of the flame. It also shows the flame higher than one inch above the log. Note: When using the heater the first time, the flame will be yellow for approximately one hour until the log cures. NOTICE: Do not mistake orange flames with yellow tipping. Dirt or other fine particles enter the heater and burn causing brief patches of orange flame. WARNING: If yellow tipping occurs, your heater could pro- duce increased levels of carbon monoxide. If burner flame pat- tern shows yellow tipping, follow instructions, bottom of this page. Yellow Tipping Top of Flame About One Inch Above Logs If burner flame pattern is incorrect, as shown in Figure 29 • turn heater off (see To Turn Off Gas to Appliance, page 14) • see Troubleshooting, pages 16 through 18 Figure 29 - Incorrect Burner Flame Pattern Figure 28 - Correct Burner Flame Pattern

to clean. Exterior • Use a soft cloth dampened with a mild soap and water mixture. Wipe the cabi- net to remove dust. CAUTION: You must keep control areas, burner, and circu- lating air passageways of heater clean. Inspect these areas of heater before each use. Have heater inspected yearly by a quali- fied service person. Heater may need more frequent cleaning due to excessive lint from carpeting, pet hair, bedding material, etc. WARNING: Turn off heater and let cool before cleaning. CLEANING BURNER INJECTOR HOLDER AND PILOT AIR INLET HOLE The primary air inlet holes allow the proper amount of air to mix with the gas. This provides a clean burning flame. Keep these holes clear of dust, dirt, and lint. Clean these air inlet holes prior to each heating season. Blocked air holes will create soot. We rec- ommend that you clean the unit every 2,500 hours of operation or every three months. We also recommend that you keep the burner tube and pilot assembly clean and free of dust and dirt. To clean these parts we recom- mend using compressed air no greater than 30 PSI. Your local computer store, hard- ware store, or home center may carry com- pressed air in a can. You can use a vacuum cleaner in the blow position. If using com- pressed air in a can, please follow the direc- tions on the can. If you don't follow direc- tions on the can, you could damage the pilot assembly. 1. Shut off the unit, including the pilot. Allow the unit to cool for at least thirty minutes. 2. Inspect burner, pilot, and primary air inlet holes on injector holder for dust and dirt (see Figure 30). 3. Blow air through the ports/slots and holes in the burner. Figure 30 - Injector Holder On Outlet Burner Tube 4. Check the injector holder located at the end of the burner tube again. Remove any large particles of dust, dirt, lint, or pet hairs with a soft cloth or vacuum cleaner nozzle. 5. Blow air into the primary air holes on the injector holder. 6. In case any large clumps of dust have now been pushed into the burner repeat steps 3 and 4. Clean the pilot assembly also. A yellow tip on the pilot flame indicates dust and dirt in the pilot assembly. There is a small pilot air inlet hole about two inches from where the pilot flame comes out of the pilot assembly (see Figure 31). With the unit off, lightly blow air through the air inlet hole. You may blow through a drinking straw if compressed air is not available.
