Observe the fl ames. The fl ames should be blue at the base and a combination
of blue/yellow at the body and tips. Flames should be 2" to 4" tall (see Fig. 24-1).
Every Real-Fyre
®
unvented gas log set leaves the factory tested and quality
checked to ensure that it has been manufactured to the strict specifi cations
to which it was submitted and approved for certifi cation. This check includes
an operational test to ensure both satisfactory combustion and operation.
Each installation site for any unvented appliance presents its own unique
combustion environment. Specifi c factors such as weather-tightness of the
home, size of the room in which the log set is installed, central heating, ceiling
fans, altitude, drafts, pet hair, carpet lint, dryer lint, the size of the fi replace, paint
or soot inside the fi replace, etc. all have an infl uence on the proper operation
of an unvented appliance and its ODS pilot system. A normally operating unvented log set will demonstrate the
following characteristics:
• A lively, realistic fl ame and front ember glow. The fl ame will be blue/yellow on the front burner and on the
rear burner.
• Clean-burning combustion that will produce no soot or smoke after normal break-in.
• Production of no odor, other than normal odors associated with the combustion of propane or natural gas.
• Production of water vapor. Water vapor helps to increase indoor humidity, which may be benefi cial during
the dry heating season.
If you operate the unvented gas log set fueled by propane gas, operating characteristics may vary as the fuel in
the tank approaches empty (less than
1
/
4
full). Sooting and other increases in combustion by-products will occur.
Turn off the log set and refi ll the propane tank.
CHECKING THE ODS PILOT FLAME APPEARANCE
WARNING: NO ADJUSTMENTS ARE TO BE MADE TO THE ODS PILOT SYSTEM. TAMPERING WITH
THIS SYSTEM CAN BE EXTREMELY HAZARDOUS.
When installing the burner assembly, it is important to visually check the ODS pilot fl ame and the burner
fl ames.
1. The ODS pilot fl ame must be present when the burner is operating. The fl ame should touch the top of the
thermocouple tip (Fig. 24-2 and Fig. 24-4).
2. If the ODS pilot fl ame does not touch the top of the thermocouple tip, then the main burner will not function
properly (see Fig. 24-3 and Fig. 24-5 for incorrect ODS pilot fl ame).
3. With the burners off and the ODS pilot fl ame off, and the assembly cool, check the burner assembly, air
intake openings on the ODS pilot, and air shutter openings on the burner for any blockages that could affect
the operation of the ODS pilot fl ame.
