Assembling the Logs
WARNING: DO NOT ADD EXTRA LOGS OR ORNAMENTS SUCH AS PINE CONES, VER- MICULITE OR ROCK WOOL. USING THESE ADDED ITEMS CAN CAUSE SOOTING.
WARNING: DO NOT PLACE ANY LAVA ROCK ON LOGS OR BURNERS. THIS MAY CAUSE SOOTING.
Step 8. The heater includes a unitized set of ceramic fiber logs. The heater and logs are assembled as shown in Figure 15. Handle these logs with great care. The logs can be easily damaged, but when handled properly they can provide years of performance and enjoyment.
After setting the logs into position as described above, ensure they are properly and firmly situated. The heater will not function as in- tended if the logs are not correctly positioned.
Periodically check the positioning of the logs.
WARNING: FAILURE TO POSITION THE PARTS IN ACCORDANCE WITH THESE DIAGRAMS OR FAILURE TO USE ONLY PARTS SPECIFICALLY APPROVED WITH THIS HEATER MAY RESULT IN PROP- ERTY DAMAGE OR PERSONAL INJURY.
Flame Appearance
REFER TO THE OPERATING INSTRUCTIONS LOCATED AT THE BACK OF THIS MANUAL BEFORE LIGHTING THE HEATER TO OBSERVE THE FLAMES.
Flames from the pilot, front and rear burner should be visually checked as soon as the heater is installed. In addition a periodic visual check of the flames should be made. The pilot flame should always be present when the heater is in operation and should just envelope the tip of the thermocouple (Figure 16 ).
WARNING: NO ADJUSTMENTS ARE TO BE MADE TO THE ODS PILOT SYSTEM. TAMPERING WITH THIS SYSTEM CAN BE EXTREMELY HAZARDOUS.

In normal operation, at full rate, after 15 min- utes the following flame appearance should be observed:
Burner Flame Characteristics – The flames should be yellow. The flames should extend about 3 – 4" above the logs for natural gas and 2 – 3" above for propane (L.P.G.) gas (Figure 18 ).
