ADJUSTMENT OF TEMPERATURE RISE

After about 5 minutes of operation, determine the furnace temperature
rise. Take readings of both the return air and the heated air in the ducts,
about six feet (1.83 m) from the furnace where they will not be affected
by radiant heat. Increase the blower speed to decrease the temperature
rise; decrease the blower speed to increase the rise.

VARIABLE SPEED MOTORS

The variable speed motor must be configured so the blower will provide
a sufficient airflow so that the furnace operates with in the temperature
rise range on the rating plate and within the application limitations
shown in Table 7 in these Instructions.

ADJUSTMENT OF FAN CONTROL SETTINGS

Heating Indoor Fan Off Delay

This furnace is equipped with a time-on/time-off heating fan control. The
fan on delay is fixed at 30 seconds. The fan off delay has 4 settings (60,
90, 120 and 180 seconds). The fan off delay is factory set to 120 sec-
onds. The fan-off setting must be long enough to adequately cool the
furnace, but not so long that cold air is blown into the heated space. The
BLOWER OFF DELAY timing may be adjusted by positioning the
jumper on two of the four pins as shown in Figure 44.

HEAT PUMP

If heat pump is installed with a furnace the HEAT PUMP jumper must be
set to YES.

FIGURE 43:

Reading Gas Pressure

DANGER

The temperature rise, or temperature difference between the return
air and the supply (heated) air from the furnace, must be within the
range shown on the furnace rating plate and within the application
limitations shown in Table 7 “RATINGS & PHYSICAL / ELECTRICAL
DATA”.
The supply air temperature cannot exceed the “Maximum Supply
Air Temperature” specified in these instructions and on the furnace
rating plate. Under NO circumstances can the furnace be allowed to
operate above the Maximum Supply Air Temperature. Operating the
furnace above the Maximum Supply Air Temperature will cause pre-
mature heat exchanger failure, high levels of Carbon Monoxide, a fire
hazard, personal injury, property damage, and/or death.
