FIRE HAZARD

Failure to follow this warning could result in personal

injury, death, and/or property damage.
Reinstall manifold pressure tap plug in gas valve to prevent

gas leak.

WARNING

FURNACE OVERHEATING HAZARD

Failure to follow this caution may result in reduced furnace

life.
Recheck temperature rise. It must be within limits specified

on the rating plate. Recommended operation is at the

mid--point of rise range or slightly above.

CAUTION

!

Adjust Thermostat Heat Anticipator

Mechanical thermostat

: Set thermostat heat anticipator to match

the amp draw of the electrical components in the R--W circuit.
Accurate amp draw readings can be obtained at the wires normally

connected to thermostat subbase terminals R and W.

The

thermostat anticipator should NOT be in the circuit while
measuring current.

1. Remove thermostat from subbase or from wall.
2. Connect an amp meter across the R and W subbase termi-

nals or R and W wires at wall. See Fig. 64.

3. Record amp draw across terminals when furnace is in low

heat and after blower starts.

4. Set heat anticipator on thermostat per thermostat instruc-

tions and install on subbase or wall.

5. Install blower access door.

Electronic thermostat

: Set cycle rate for 3 cycles per hr.

Check Safety Controls

The flame sensor, gas valve, and pressure switch were all checked
in the Start--up procedure section as part of normal operation.

1. Check Main Limit Switch

This control shuts off combustion system and energizes air--

circulating blower motor, if furnace overheats. By using this
method to check the temperature limit control, it can be es-
tablished that the limit is functioning properly and that the

limit will operate if there is a restricted return--air supply or
motor failure. If the limit control does not function during

this test, the cause must be determined and corrected.

a. Run furnace for at least 5 minutes.

b. Gradually block off return air with a piece of cardboard or

sheet metal until the limit trips.

c. Unblock return air to permit normal circulation.

d. Burners will re--light when furnace cools down.

2. Check Pressure Switch(es)

This control proves operation of the draft inducer blower.

a. Turn off 115--v power to furnace.

b. Disconnect inducer motor lead wires from wire harness.

c. Turn on 115--v power to furnace.

d. Set thermostat to “call for heat” and wait 1 minute. When

low pressure switch is functioning properly, hot surface
ignitor should

NOT

glow and control diagnostic light

flashes a status code 31. If hot surface ignitor glows when

inducer motor is disconnected, shut down furnace immedi-
ately.

e. Determine reason low pressure switch did not function

properly and correct condition.

f. Turn off 115--v power to furnace.

g. Reconnect inducer motor wires, replace door, and turn on

115--v power.

h. Blower will run for 90 sec before beginning the call for

heat again.

i. Furnace should ignite normally.

Checklist

1. Put away tools and instruments. Clean up debris.
2. Verify that the jumper is removed from the TEST/TWIN

terminal. Verify that there is nothing plugged into the PLT
connector. (Note: If there is a jumper connector plugged

into PLT, remove it and discard.) See Fig. 36.

3. Verify that the Blower/Heat Off Delay jumpers are set as

desired. See Fig. 36 and 72.

4. Verify that the blower (lower door in upflow position) and

control (“Main” or upper door in upflow position) doors are

properly installed.

5. Verify that the Status LED glows. If not, check that the

power supply is energized and that the blower door is

secure. See Fig. 65 to interpret diagnostic codes.

6. Cycle test furnace with room thermostat to be sure that it

operates properly with the room thermostat. Check all
modes including Heat, Cool and Fan.

7. Check operation of accessories per manufacturer’s

instructions.

8. Review Owner’s Manual with owner.

9. Attach entire literature packet to furnace.
