appropriate terminal on the blower relay. Figure
33 shows high fire heating and cooling using the
same blower speed.

The integrated control  is factory set to start the
circulating air blower 30 seconds after the gas
valve is opened. The integrated control is fac-
tory wired to turn the blower motor off 120
seconds after the gas valve is closed. If neces-
sary for comfort, the “off” time may be changed
by adjusting the Blower Off jumper on the
integrated control.  See Figure 34 for blower on
and off time adjustments.

!  WARNING:

To avoid electric shock, personal in-
jury, or death, disconnect the electric
power before performing any mainte-
nance.

Verifying Burner Operation

To verify operation of the burners, make sure
that the furnace door is in place and that there
is power to the furnace. Set the thermostat to a
temperature above room temperature and ob-

serve the ignition sequence. The burner flame
should carry over immediately between all burn-
ers. The flames should be blue, without yellow
tips. Flames should extend from each burner
without lifting off, curling, or floating. After veri-
fying satisfactory flame characteristics, set the
thermostat to a temperature below room tem-
perature and verify that the burner flame extin-
guishes completely.

Verify Operation of the Supply Air Limit
Switch

To verify operation of the supply air  limit switch,
make sure that the blower door is in place and
that there is power to the furnace. Block the
return airflow to the furnace by installing a close-
off plate in place of or upstream of the filter(s).
Set the thermostat to a temperature above
room temperature and verify that the Sequence
of Operation is as described in these instruc-
tions. The limit switch should function to turn off
the gas valve within approximately four minutes
(the exact time depending on the efficiency of
the close-off in blocking the return air to the
furnace). The circulating air and combustion
blowers should continue to run when the limit
switch opens. Remove the close-off immedi-
