To adjust the pilot flame:
1. Remove the pilot adjustment cover screw.
2. Adjust the pilot adjustment screw to achieve the proper
pilot flame.
3. Replace the pilot adjustment cover screw after the pilot
flame is set.
To remove the pilot assembly:
1. Disconnect the wiring from the control board to the pilot
assembly.
2. Remove the two (2) #8 screws holding the pilot assem-
bly in place.
3. Remove the pilot assembly.
ADJUSTMENT OF TEMPERATURE RISE
The temperature rise (or temperature difference between the
return air and the heated air from the furnace) must lie within
the range shown on the rating plate and the data in Tables 3
and 4.
After the temperature rise has been determined, the CFM can
be calculated as follows:
After about 20 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 from the furnace where
they will not be affected by radiant heat. Increase the blower
CFM to decrease the temperature rise; decrease the blower
CFM to increase the rise.
DIRECT DRIVE BLOWER
All units have direct drive multi-speed blower motors. Refer to
the unit wiring diagram and connect the blower motor for the
desired motor speed.
CHECKING GAS INPUT
NATURAL GAS
1. Turn off all other gas appliances connected to the gas
meter.
2. With the furnace turned on, measure the time needed for
one revolution of the hand on the smallest dial on the
meter. A typical gas meter usually has a 1/2 or a 1 cubic
foot test dial.
3. Using the number of seconds for each revolution and the
size of the test dial increment, find the cubic feet of gas
consumed per hour from Table 12.
If the actual input is not within 5% of the furnace rating with
allowance being made for the permissible range of the regu-
lator setting, replace the orifice spuds with spuds of the
proper size.
NOTE: To find the BTU input, multiply the number of cubic
feet of gas consumed per hour by the BTU content
of the gas in your particular locality. (Contact your
gas company for this information since it varies
widely from city to city.)
