INSTALLING YOUR FURNACE
determined by step (2), then:
Seconds per hour = 3,600
Input = 1,000 x 3,600 / 34 = 106,000 BTU/hr.
This measured input must not be greater than the
input indicated on the nameplate of the furnace.
4. Relight all other appliances turned off in Step 1 above. Be
sure all pilots are operating.
CHECK THERMOSTAT
Check thermostat operation. When set above room temperature
shown on the thermostat, the main burner should light. Make certain
the thermostat turns off the furnace when the room temperature
reaches the selected setting and starts the furnace when room
temperature falls a few degrees below the thermostat setting.
OPERATING YOUR FURNACE
CHECK PILOT BURNER
The pilot flame must surround the generator tip from 1/4 to
3/8-inches. Pilot flame is preset at the factory, so ordinarily it does
not require field adjustment.
Figure 19
. On new installations, the gas
lines will be filled with air and may take several minutes to establish a
pilot flame.
BURNER FLAME CHARACTERISTICS
Start the furnace and let it operate at least ten minutes. Open
the access door to view the burner flame. Limit your movements
near the furnace a few more minutes before making your final
observations. The flame may look yellow due to dust particles in
the room air. The flame should change to a nice blue color with firm
inner and secondary cones. An occasional flash of orange might be
seen as dust particles burn in the flame. This is normal. No burner
adjustment is provided, or is necessary. (Figure 20).

NORMAL APPEARANCE
NATURAL GAS:
1. Inner cone-blue in color-3/8 to 5/8-inches above ports.
2. Secondary inner cone-light blue in color-1 to 2-inches
above ports.
3. Total flame-from blue in color to nearly invisible -
approximately 6-inches above ports.
PROPANE GAS:
1. Inner cone-blue in color-1/2 to 3/4-inches above ports.
2. Secondary inner cone-light blue in color-1 to 2-inches
above ports.
3. Total flame-from blue in color to nearly invisible-
approximately 6-inches above ports.
ABNORMAL APPEARANCE
LAZY FLAME:
Long, soft yellow cones moving around in the combustion chamber
lifting from ports (insufficient air).
