Thermostat Installation (not allowed in US installations)
wall switch installation
The burner control switch is located in the centre of the control department opening. For your convenience, the unit can
also be operated by a thermostat or a wall switch control. Electronic are available from any authorized CFHMfg dealer.
Please note, bedroom installations require the use of a wall thermostat. Mount the thermostat or switch in the desired
location and run “two conductor thermostat wires” to the heater’s lower right hand corner, close to the gas supply line.
Note: The wall switch MUST be rated for electronic

For maintenance, proper re-assembly and resealing of the venting system is required.
The appliance should be inspected before use and at least annually by a professional service
person.
More frequent cleaning may be required due to excessive lint from carpet bedding material etc. It is imperative
that control compartment, covers of the appliance to be kept clean.
Pressure testing the supply line for leaks
The appliance and its individual shut-off valve must be disconnected from the gas supply piping system during any pressure
testing of the system at test pressures in excess of ½ psig (3.4kPa). The appliance must be isolated from the gas supply piping
system by closing its individual manual shut-off valve during any pressure testing of the gas supply piping system at test
pressures equal to or less than ½ psig (3.5kPa). Failure to do so will damage the appliance’s gas valve. Such damage is not
covered by the manufacturer’s warranty.
When testing for leaks:
Make sure that the appliance is turned off.
Open the manual shut-off valve.
Test for leaks by applying a liquid detergent or soap solution to all ball joints. Bubbles forming indicate a gas leak.
Correct any leak detected immediately.
Never use an open flame to check for leaks.
The pressure test point locations are built in to the regulator that controls the burner manifold pressure. The correct pressure
range is shown in the table in the specification section of this manual. The pressure check should be made with the burner lit.
See lighting instruction section for full operating details.
