Complete Installation
IMPORTANT: Do not use this furnace if any part has been under
water. Immediately call a qualified person to inspect the furnace
and to replace any part of the control system and gas control
which has been under water.
1. Check that you have all of your tools.
2. Dispose of/recycle all packaging materials.
3. Check the furnace in its final location. Be sure the vent is not
blocked.
Start-up Procedure and Adjustment
This furnace must have a 115 VAC power supply properly
connected and grounded. Proper polarity must be maintained for
correct operation. See "Operational Checks."
Heat Anticipator Setting
The heat anticipator in the room thermostat must be correctly
adjusted to obtain the proper number of cycles per hour and to
avoid "overshooting" of the setting. Set the heat anticipator
setting to 0.7 amps. Follow the thermostat manufacturer's
instructions on how to adjust the heat anticipator setting.
Drain Trap Priming
The drain trap must be primed prior to the furnace start-up. To
prime, fill the drain trap with water. This ensures proper furnace
drainage upon start-up and avoids the possibility of flue gases
escaping through the drain system.
Furnace Operation
1. Purge the gas lines of air prior to start-up.
NOTE: Be sure not purge lines into an enclosed burner
compartment.
2. Check for leaks using an approved chloride-free soap and
water solution, an electronic combustible gas detector or
other approved method.
3. Verify that all required kits (propane gas, high altitude, etc.)
have been appropriately installed.
Furnace Start-up
1. Close the manual gas shutoff valve external to the furnace.
2. Turn off the electrical power to the furnace.
3. Set the room thermostat to the lowest possible setting.
4. Remove the burner compartment door.
NOTE: This furnace is equipped with an ignition device which
automatically lights the burner. Do not try to light the burner by
hand.
5. Move the furnace gas control valve manual control to the OFF
position.
6. Wait 5 minutes, and then check for a gas odor.
NOTE: Check near the floor as some types of gas are heavier
than air.
7. After 5 minutes, move the furnace gas control valve manual
control to the ON position.
8. Replace the burner compartment door.
9. Open the manual gas shutoff valve external to the furnace.

10. Turn on the electrical power to the furnace.
11. Adjust the thermostat to a setting above room temperature.
12. After the burners are lit, set the thermostat to the desired
temperature.
Measure Temperature Rise
1. Adjust room thermostat to the highest temperature setting
possible.
2. After 20 minutes of heating operation, measure the furnace
temperature rise. Take air temperature readings in both the
return air ducts and the heated air ducts (about 72" [1.8 m]
from the furnace where they will not be affected by radiant
heat) as shown.
NOTE: If more than one run of return or heated air ducts are
used, air temperature measurements should be taken in each
duct. These measurements can be converted to an average
to obtain the temperature rise of the whole system.

3. If furnace doesn't maintain temperature rise within the range
shown on the furnace rating plate, adjust the blower speed.
Final Checklist
Cycle the furnace with the thermostat at least 3 times. Verify
cooling and fan only operation.
Review the owner's manual with the homeowner and discuss
proper furnace operation and maintenance.
Leave literature packet near furnace.
Furnace Shut Down
1. Set the thermostat to the lowest setting.
The integrated control will close the gas control valve and
extinguish the flame. Following a 15-second delay, the
induced draft blower will be de-energized. After a 120-, 150-,
180- or 210-second delay period (field-selectable delay OFF
[90, 120, 150, 180] plus a 30-second ramp down), the
circulator blower deenergizes.
2. Remove the burner compartment door and move the furnace
gas control valve manual control to the OFF position.
3. Close the manual gas shutoff valve external to the furnace.
4. Replace the burner compartment door.
