Revision: CP-CAUA-GC (04-21) 170635-A GAS CONVERSION KIT INSTALLATION FOR GAS-FIRED INDOOR HEATER Supersedes: CP-CAUA-GC (01-18) PN170635R9 MODEL CAUA GENERAL INFORMATION The gas conversion kits in these instructions are for model CAUA heaters equipped with specific single-stage or two-stage gas valves. The kits are for operation at sea level. When converting a unit with a two-stage valve (option AG2), check for the valve manufacturer. If the unit has a two-stage White-Rodgers valve, a new two-stage gas valve is required. Gas Valve Identification In order to verify which conversion kit is compatible with your heater, it is necessary to know the type of gas valve on the heater. Refer to the unit rating plate for the complete model number of the heater. Also, refer to the manufacturer’s name and number found on the gas valve. Match the model number of the valve to the one listed in the kit—if different, contact your manufacturer representative to select and verify parts required for gas conversion.
