CAUTION
It is imperative that this device be installed by a qualified service
technician.
A positive pressure venting system (Sealed Combustion System
or Direct Vent) MUST NOT use the BVSO. Follow the instructions
supplied with the venting system.
This
device
is
designed
to
detect
the
insufficient
evacuation
of
combustion
gases
in
the
event
of
a
vent
blockage.
In
such a case the thermal switch will shut down the oil burner.
The device will then need to be re-armed MANUALLY.
Refer to the detailed instructions and wiring diagrams supplied with the
BVSO for the installation and wiring procedures. The length of wires
supplied with the unit is such that the safety device must be installed
between the flue outlet of the appliance and the draft regulator, as

continues to run to the end of the cool-down cycle.
If the test is not in line with the above, call a QUALIFIED SERVICE
TECHNICIAN.
2.8
COMBUSTION AIR SUPPLY
AND VENTILATION
WARNING
POISONOUS CARBON MONOXIDE GAS HAZARD.
Comply with NFPA 31 (U.S.) and CSA B139 (Canada) standards
for the installation of Oil Burning Equipment and applicable
provisions of local building codes to provide combustion and
ventilation air.
Failure to provide adequate combustion and ventilation air can
result in death, bodily injury and/or property damage.
Oil furnaces must have an adequate supply of combustion air. It is
common practice to assume that older homes have sufficient infiltration
to accommodate the combustion air requirement for the furnace.
However, home improvements such as new windows, doors, and
weather stripping have drastically reduced the volume of air infiltration
into the home.
Refer to oil furnace installation codes relative to combustion and
ventilation air requirements.
Consult Section 2.1.1 in this manual,
specifically for units installed in an enclosed space.
Home air exhausters are common. Bathroom and kitchen fans, power
vented clothes dryers and water heaters all tend to create a negative
pressure condition in the home.
Should this occur the chimney
becomes less and less effective and can easily downdraft. In certain
cases, mechanically supplied air, by way of a blower, interlocked with
the unit, is necessary. It is the installer’s responsibility to check that.
2.8.1
Contaminated Combustion Air
Installations in certain areas or types of structures will increase the
exposure to chemicals or halogens that may harm the furnace. These
conditions will require that only outside air be used for combustion.
The following areas or types of structures may contain or be exposed
to certain substances, potentially requiring outside air for combustion:
1. Commercial buildings;
2. Buildings with indoor pools;
3. Furnaces installed near chemical storage areas.
Exposure to the following substances:
a) Permanent wave chemicals for hair;
b) Chlorinated waxes and cleaners;
c) Chlorine based swimming pool chemicals;
d) Water softening chemicals;
e) De-icing salts or chemicals;
f) Carbon Tetrachloride;
g) Halogen type refrigerants;
h) Cleaning solvents (such as perchloroethylene);
i) Printing inks, paint removers, varnishes, etc. ;
j) Hydrochloric acid;
k) Solvent based glue;
l) Antistatic fabric softeners for clothes dryers;
m) Acid based masonry cleaning materials.
2.8.2
Burner with Outdoor Combustion Air
Kit
Some burners are designed to function with combustion air taken
directly from the outside.
Follow the instructions provided with the
burner, the fresh-air supply kit or the side-wall venting kit.
2.9
OIL TANK
WARNING
FIRE AND EXPLOSION HAZARD.
Use only approved heating type oil in this furnace. DO NOT
USE waste oil, used motor oil, gasoline or kerosene.
Use of these will result in death, bodily injury and/or property
damage.
CAUTION
When a 0.75 USGPH or smaller nozzle is used, a 10 micron or finer
filter, must be installed on the oil supply line to the furnace inside the
building where the unit is located.
This is a requirement in order for the heat exchanger warranty to
remain in force.
6
Check your local codes for the installation of the oil tank and
accessories.
At the beginning of each heating season or once a year, check the
complete oil distribution system for leaks.
Ensure that the tank is full of clean oil. Use No.1 or No.2 Heating Oil
(ASTM D396 U.S.) or in Canada, use No.1 or No.2 Furnace Oil.
A manual shut-off valve and an oil filter shall be installed in sequence
from tank to burner. Be sure that the oil line is clean before connecting
to the burner. The oil line should be protected to eliminate any possible
damage.
Installations where the oil tank is below the burner level
must employ a two-pipe fuel supply system with an appropriate fuel
pump. A rise of 2.4 m (8’) and more requires a two stage pump and
a rise greater than 4.9 m (16’) an auxiliary pump. Follow the pump
instructions to determine the size of pipe needed in relation to the rise
or to the horizontal distance.
2.10
DUCTING
WARNING
POISONOUS CARBON MONOXIDE GAS HAZARD.
DO NOT draw return air from inside a closet or utility room.
Return air MUST be sealed to the furnace casing.
Failure to properly seal ducts can result in death, bodily injury
and/or property damage.
The ducting must be designed and installed according to approved
methods, local and national codes as well as good trade practices.
When ducting supplies air to a space other than where the furnace is
located, the return air must be sealed and also be directed to the space
other than where the furnace is located.
2.10.1
Air filter
A properly sized air filter must be installed on the return air side of the
unit. Refer to the Technical Specifications in Table 6, for the correct
dimensions. Also refer to Section 2.2 and the instructions supplied with
the filter.
2.11
SUPPLY AIR ADJUSTMENTS
(4 SPEED MOTORS)
On units equipped with 4-speed blower motors, the supply air must
be adjusted based on heating/air conditioning output and the static
pressure of the duct system. For the desired air flow refer to Table
1 as well as the table 8 based on static pressure in the Technical
Specifications section of this manual.
Figure 8 – Blower “OFF” delay - Board #ST9103A
To effect the adjustment, the RED (for heating) and BLUE (for cooling
and heat pump) wires can be changed on the motor. Also, refer to the
position of the wires on the electronic board of the unit and consult
the wiring diagrams.
If the heating and air conditioning speeds are
the same, the RED wire must be moved to “UNUSED LEADS” on the
electronic board and the jumper provided with the BLUE wire must be
used between the “HEAT” and “COOL” terminals.
The blower start/stop delays can be adjusted by positioning the DIP
switches on the electronic board as shown in the following figures. For
upflow installation, the recommended blower ON delay is 60 seconds
and blower OFF delay 2 minutes.

INSTALLATION OF
ACCESSORIES
WARNING
ELECTRICAL SHOCK HAZARD.
Turn OFF electrical power at the fuse box or service panel
before making any electrical connections and ensure a proper
ground connection is made before connecting line voltage.
Failure to do so can result in death or bodily injury.
2.13.1
Humidifier (HUM)
The electronic board supplies 120 VAC for a humidifier on the HUM
terminal.
It supplies 120 VAC electric power when the burner is in
operation.
A 24 VAC signal can also be supplied from the W and C terminals on
the blower electronic board to activate a switching relay.
Also refer to the instructions supplied with the accessory.
2.13.2
Electronic Air Cleaner (EAC)
The EAC terminal on the electronic board supplies 120 VAC when the
blower is operating in the heating or air conditioning mode. This signal
8
can be used to activate an electronic air cleaner that is not equipped
with an air flow switch.
If the cleaner is equipped with an air flow
switch, the S terminal on the PSC electronic board or one of the 120
VAC terminals on the ECM electronic board can be used to provide a
constant supply of 120 VAC.
Also refer to the instructions supplied with the accessory.
2.13.3
Air Conditioner (or Heat Pump)
An air conditioning coil may be installed on the supply air side ONLY.
WARNING
POISONOUS CARBON MONOXIDE GAS HAZARD.
Install the evaporator coil on the supply side of the furnace
ducting ONLY.
An evaporator coil installed on the return air side of the ducting
can cause condensation to form inside the heat exchanger,
resulting in heat exchanger failure. This in turn, can result in
death, bodily injury and/or property damage.
A clearance of 15 cm (6") is required between the bottom of the coil
drain pan and the top of the heat exchanger. If a heat pump is installed,
a “dual-energy” thermostat, or other control is required, in order to
prevent the simultaneous operation of the furnace and the heat pump. It
also prevents a direct transition from heating by way of the heat pump to
heating with oil. Refer to the thermostat instructions or those of another
control used for the proper wiring.
If a coil blower compartment is used, install air tight, motorized and
automatic air dampers.
Cold air coming from the coil and passing
across the furnace can cause condensation and shorten the life of the
heat exchanger.
2.13.4
Emergency Heating Mode - variable
speed Motor (ECM)
If the ECM blower motor is defect and that no spare are available right
away, you can temporarily replace it with a conventional fractional PSC
blower motor. Connect neutral wire to neutral terminal on the control
panel of the machine and the hot line to the EAC terminal. This one is
working as long as heating or cooling is requested, and the blower will
work until a new ECM motor is installed.
CAUTION
We recommend to use this mode only for a short period of time
since it affects the efficiency of the unit and the user comfort..

OPERATION
3.1
START-UP
CAUTION
DO NOT START THE BURNER UNLESS THE BLOWER ACCESS
DOOR IS SECURED IN PLACE.
Before starting up the unit, be sure to check that the following
items are in compliance:
1) The electrical installation, the oil supply system, the venting
system, combustion air supply and ventilation;
2) The blower access door is in place and the blower rail locking
screws are well tightened;
3) The Blocked Vent Shut-Off (BVSO) is installed according to
instructions (for chimney venting);
4) The oil supply valve is open;
5) The burner ‘’Reset” button is well pushed in or re-armed;
6) The preliminary air adjustments on the burner comply with the
technical specifications in this manual;
7) The blower speed adjustments for heating and air conditioning
are appropriate and according to the specifications in this
manual;
8) The blower start/stop delays are satisfactory;
9) The thermostat of the room is in the heating mode and is set
higher than the ambient temperature.
To start the unit, turn the main electrical switch on.
3.2
OPERATING SEQUENCE OIL
HEATING MODE
1) The W-R contact closes;
2) The burner motor starts up to pre-purge the combustion
chamber for a period of 10 to 15 seconds. During that time a
spark is established on the electrodes;
3) The solenoid valve opens and a flame is established. Shortly
after, the electrodes cease to spark;
4) Then the blower runs up to full speed. The delay depends on
the adjustments that were made on the electronic board, which
controls the blower motor.
Refer to Sections 2.11 and 2.12
above as well as to the airflow tables 7 and 8 for more details.
5) When the call for heat is satisfied, the solenoid valve closes,
the flame goes out and the burner motor stops (after post purge
delay, if applicable).
6) The blower stops shortly after the burner. The delay depends
on the adjustments that were made on the electronic board that
controls the blower. Refer to Sections 2.11 and 2.12 above as
well as to the airflow table 7 and 8 for more details.
Note: A detailed operating sequence of the oil burner is outlined in the
instructions provided with the burner.
3.3
CHECKS AND ADJUSTMENTS
3.3.1
Purging the oil line
Open the bleed port screw and start the burner. Allow the oil to drain
into a container for at least 10 seconds. The oil should flow absolutely
free of white streaks or air bubbles to indicate that no air is being drawn
into the suction side of the oil piping and pump.
Slowly close and
tighten the bleed screw. Once closed, the flame will light up.
3.3.2
Pressure adjustment
The oil pressure must be adjusted according to the Technical
Specifications of this manual. An adjustment screw and a connection
for a pressure gauge are located on the oil pump for that purpose. Also
refer to the burner instruction manual.
9
The heat exchanger metal surfaces may have oil and the baffle
insulation also contains binders.
These products will burn or
evaporate when the unit operates for the first time.
Because
of this,
the smoke reading may be inexact during the first
minutes of operation.
Therefore, the unit must operate during
at least 60 minutes before taking any readings to adjust the
combustion quality.
Let the unit cool down before making any
adjustments.
IMPORTANT
The combustion check verification MUST be performed after
the nozzle replacement or the burner cleaning.
After these
manipulations,
the
combustion
parameters
are
necessarily
modified. Refer also to the burner instruction manual.
1. Drill a test hole in the flue pipe, approximately 18 inches from
the furnace breech. Insert the smoke test probe into the hole.
For installation using a sidewall venting, use the orifice provided
on the breech plate;
2. From a cold start, let the unit operate for about 5 minutes;
3. Set the burner air setting until you have between 0 and 1 on the
Bacharach Scale (or a “trace”);
4. Take a CO2 sample at the same test location where the #1
smoke reading was taken and make note of it. Example: 13.8%
of CO2 or 2.5% of O2;
5. the burner air setting to obtain a CO2 reading 1.5% lower (or a
O2 reading 2.0% higher) than the reading associated with the
“trace” of smoke. Example: 12.3% of CO2 or 4.5% of O2;
6. This method of adjusting the burner will result in clean
combustion (Bacharach smoke scale between 0 and a trace)
and ensure the proper functioning of the system. The optimum
CO2 level is around 12% to 13% (or 3.5% to 5.0% of O2).
3.3.4
Draft Regulator adjustment
On chimney installations only, a barometric draft regulator (supplied
with the furnace) must be installed, in order to ensure proper draft
through the furnace. The barometric damper must be mounted with the
hinge pins in a horizontal position and the face of the damper vertical
for proper functioning (see instructions included with the damper.) After
the furnace has been firing for at least five minutes, the draft regulator
should be set to between -0.025" and -0.060" W.C.
3.3.5
Overfire pressure test
The overfire draft that is taken through the observation port, located
above the burner, is a measurement necessary to determine if there
is a blockage in the heat exchanger or the flue pipe.
Refer to the
Technical Specifications in this manual for overfire pressure values. A
high pressure condition may be caused by excessive combustion air,
due to the air band being too wide open, or a lack of flue draft (chimney
effect) or some other blockage, such as soot in the secondary section
of the heat exchanger or the use of an oversize nozzle input or high
pressure pump.
3.3.6
Vent Temperature Test
1. After
having
adjusted
the
burner
combustion,
insert
a
thermometer into the test hole in the breech pipe;
2. The total vent temperature should be between 204 and 302°C
(400 and 575°F). If not, check for improper air temperature rise,
pump pressure, nozzle size or a badly sooted heat exchanger.
CAUTION
Low flue gas temperature increases the risk of condensation.
Adjust the total temperature at or higher then 204°C (400°F) in order
for the heat exchanger warranty to remain in force.
3.3.7
Supply Air Temperature Rise Test
1. Operate the burner for at least 10 minutes;
2. Measure the air temperature in the return air plenum;
3. Measure the air temperature in the largest trunk coming off the
supply air plenum, just outside the range of radiant heat from
the heat exchanger. 0.3 m (12") from the plenum of the main
take-off is usually sufficient;
4. The temperature rise is calculated by subtracting the return air
temperature from the supply air temperature;
5. If the temperature rise is lower or exceeds the temperature
specified in Table 6, change to the next lower or higher blower
speed tap, until the temperature rise falls to the target. If the
excessive temperature rise cannot be increased or reduced by
changing fan speed, investigate for ductwork obstructions, dirty
or improper air filter, improper firing caused by improper pump
pressure or nozzle sizing.
3.3.8
Limit control check
After operating the furnace for at least 15 minutes, restrict the return
air supply by blocking the filters or the return air register and allow the
furnace to shut off on High Limit. The burner will shut off but the blower
will continue to run.
Remove the obstruction and the burner should restart after a few
minutes.
The time required for the restart also depends on the
adjustment of the blower “OFF” delay.
3.3.9
Restart after Burner Failure
1. Set the thermostat lower than room temperature;
2. Press the reset button on the burner primary control (relay);
3. Set the thermostat higher than room temperature;
4. If the burner motor does not start or ignition fails, turn off
the disconnect switch and CALL A QUALIFIED SERVICE
TECHNICIAN.
CAUTION
Do not attempt to start the burner when excess oil has
accumulated, when the furnace is full of vapour or when the
combustion chamber is hot.
4

PreRun and ShortRun are the periods of time when the blower starts at very low CFM to minimize the distribution of
cool air in the system and then runs up to normal speed.
Off Delay is the time required to cool down the heat exchanger with low CFMs, to minimize cool draft in the air distribution
system.
