Furnace Location_____________________________
Furnace Orientation:
Gas Adjustment
LOCAL GAS HEAT CONTENT_____________(btu/cu. ft.)
(contact your local gas utility-not required for propane)
INLET SUPPLY PRESSURE**
MANIFOLD PRESSURE: High fire___________ in.
**Supply pressure should be checked with furnace and all other gas appliances running
FIRING RATE:
Firing rate = heat content (btu/cu. ft.) X size of the dial (cu. ft/rev) X # of rev. per 60 sec (rev/sec) X 3600 (sec/hr)
Example- (1050 btu/cu. ft.) X (0.5 cu. f t ./rev.) X (2 revs./60sec) X (3600 sec/hr)= 63,000 btu/hr
OR use the "Gas Rate" chart in the startup and adjustment section of the installation manual
HIGH HEAT_________________ btu/hr
LEAVING AIR TEMPERATURE
RETURN AIR TEMPERATURE
TEMPERATURE RISE
Temperature rise is equal to the supply air temp minus the return air temp @ steady state operation.
The supply temperature should be measured away from the line of sight of the Heat Exchanger
