Page 11: Safe Operation Precautions
IF HEATER FAILS TO START: Press manual reset button at rear of burner. Check gas pressure supply. Supply and manifold pressure must follow those on rating plate. Ensure proper power supply and extension cord is being used. If heater fails to ignite after 3 attempts, call your supplier for service. SAFE OPERATION PRECAUTIONS: For use with propane or natural gas only. -
Page 12: Firing Rate
COMBUSTION AIR ADJUSTMENTS: NOTE: Proper combustion air adjustment must be achieved using a certified combustion analyzer to ensure complete combustion. The air adjustment should be made to achieve 10% CO on natural gas and 12% CO on propane. SETTING THE AIR ADJUSTMENT PLATE A) Regulation of the combustion air flow is made by adjustment of the manual AIR ADJUSTMENT PLATE (1) after loosening the FIXING SCREWS (2 and 3). - Page 13 TEMPERATURE FEELER GAUGE ADJUSTMENT (ATTACHED TO FAN SWITCH) The temperature feeler gauge is required to be always touching the heater exchanger. The temperature feeler gauge controls the air flow over the fan switch, which eliminates any unnecessary fan cycling. The temperature feeler gauge can be adjusted for different outside temperatures, by rotating the location of the temperature feeler gauge holes.

Page 14: Burner Dimensions
In extreme cold conditions, cover the holes on the temperature feeler gauge using foil tape. Ensure that the temperature feeler gauge is readjusted for warmer weather conditions. Failure to do so may result in burning out fan switches – not covered under warranty.
