!WARNING
CARBON CAN BE DISTRIBUTED IN SURROUNDING LIVING AREAS IF THE AIR SHUTTER IS
IMPROPERLY ADJUSTED.
FAILURE TO KEEP THE PRIMARY AIR OPENING(S) OF THE BURNER (S) CLEAN MAY RESULT IN
SOOTING AND PROPERTY DAMAGE.

The air shutter settings are factory set for most installations. However, adjustment may be required depending on fuel type, vent performance and altitude.
Closing the air shutter will cause a more yellow flame, but can lead to carboning. Opening the air shutter will cause a more blue flame, but can cause flame lifting from the burner ports. The flame may not appear yellow immediately; allow 15 to 30 minutes for the final flame colour to be established.
7.2FLAME CHARACTERISTICS
It’s important to periodically perform a visual check of the pilot and burner flames. Compare them to the illustra- tions provided. If any flames appear abnormal call a service person.
8.0 MAINTENANCE
54.5
!WARNING
TURN OFF THE GAS AND ELECTRICAL POWER BEFORE SERVICING THE APPLIANCE.
Visually inspect the appliance for carbon buildup.
Using a small whisk or brush, brush off the excess carbon and vacuum up or sweep into the garbage. Check the appliance for broken logs and corrosion of the main burner base.
8.1OXYGEN DEPLETION SENSOR (ODS) CLEANING
This procedure must be performed by a qualified service person!
Inspect the pilot for any visible contamination or debris (usually lint, pet
hair, spider webs, carpet fibre, etc.) and remove.
Disconnect the pilot from the pilot tubing line, using a 7/16” wrench. Blow out the housing in the same direction as the gas flow. 
for leaks.
If this does not improve the performance, 
replace the ODS with an exact replacement. The device is tamper resistant with no field serviceable parts.
INCORRECT PILOT FLAME
(Flame lifts upwards,
becomes unstable with more
of an orange tip).
