The flame height and BTU input may be altered by rotating the flame control valve from low to high.

CAUTION: DO NOT ATTEMPT TO REDUCE OR ALTER THE FLAME BY POSITIONING THE GAS VALVE IN OTHER THAN THE FULL “ON” POSITION.

The air shutter on the venturi tube has been set at the factory for both natural and propane gas models, refer to Figure 22 for air shutter set- tings.

Flame Appearance

REFER TO THE OPERATING INSTRUCTIONS LOCATED AT THE BACK OF THIS MANUAL BEFORE LIGHTING THE HEATER TO OBSERVE THE FLAMES.

Note: Instructions are also found on the pull- out panel located in the l ower control compart- ment of the appliance.

Note: The door switch must be held closed for burner operation when testing.

Flames from the pilot and main burner should be visually checked when the appliance is installed. In addition a periodic visual check of the flames should be made throughout the life of the appliance. The pilot flame should always be present when the heater is in operation and should just envelope the tip of the thermo- couple (Figure 23 ). The main burner flames must not impinge on the logs with the excep- tion of the charred areas, flame appearance should be as shown in Figure 24.

WARNING: NO ADJUSTMENTS ARE TO BE MADE TO THE ODS PILOT SYSTEM. TAMPERING WITH THIS SYSTEM WILL VOID THE WARRANTY AND CAN BE EX- TREMELY HAZARDOUS.

A pilot flame that does not envelope the ther- mocouple tip, will cause the main burner to function improperly. If the pilot flame does not envelope the thermocouple tip as shown in Figure 23, contact your service representative. In normal operation after 15 minutes the fol- lowing main burner flame appearance should be observed (Figure 24 ).

NOTE: DIAGRAMS & ILLUSTRATION NOT TO SCALE.

Rear Burner Flames – The rear flames rising in front of center and rear logs should be yellow and extend about 2 ¹⁄₂ – 3" above the large logs for natural gas and 1 ¹⁄₂ – 2 ¹⁄₂” above for propane gas.

Front Burner Flames – The flames at the front of the main burner will be blue becoming yellowish as they hit the bark-like texture on the front face of the front base log.

Low flame setting observable characteristics are approximately 2" to 2 ¹⁄₂” shorter than the flames are on high.

Refer to the Operation and Maintenance in- structions on page 12 of this manual for flame adjustment procedures.

Appliance Operation

WARNING: THE LOWER CONTROL COM- PARTMENT AREA AND LOWER CONTROL COMPARTMENT ACCESS DOOR ARE EX- TREMELY HOT WHEN THE APPLIANCE IS INOPERATION. EXERCISEEXTREMECARE WHEN ACCESSING THIS AREA. TOUCH ONLY THE FAR ENDS OF THE LOWER CONTROL COMPARTMENT DOOR WHEN OPENING WHILE THE APPLIANCE IS HOT.

Step 11. Checking the System – With gas line installed run initial system checkout before closing up the front of the unit. Follow the pilot lighting instructions on pages 17.

Note: Instructions are also found on the pull out panel located in the lower control compart- ment of the appliance.

To light the burner; turn “ON” the optional remote wall switch (if installed) and rotate the gas valve control knob counterclockwise to the “ON” position.

Note: The door switch must be held closed for burner operation when testing.

When first lighting the appliance, it will take a few minutes for the line to purge itself of air. Once purging is complete, the pilot and burner will light and operate as indicated in the instruc- tion manual. Subsequent lightings of the appli- ance will not require such purging. Inspect the pilot flame (remove logs, if necessary, handling carefully).

The pilot flame should be steady, not lifting or floating. Flame should be blue in color with traces of orange at the outer edge.
