SET TEMPERATURE RISE
UNIT DAMAGE HAZARD
Failure to follow this caution may result in unit component
damage.
Temperature rise must be within limits specified on furnace
rating plate. Recommended operation is at midpoint of rise
range or slightly above.
CAUTION
!
Place SW-1 in ON position. Jumper R to W/W1 and W2 to check
high-gas-heat temperature rise. To check low-gas-heat
temperature rise, remove jumper to W2. Determine air
temperature rise for both high and low gas heat. Do not exceed
temperature rise ranges specified on unit rating plate for high and
low gas heat.
This furnace must operate within the temperature rise ranges
specified on the furnace rating plate. Determine the air
temperature as follows:
a. Place duct thermometers in return and supply ducts as
close to furnace as possible. Be sure thermometers do
not “see” heat exchangers so that radiant heat does not
affect thermometer readings. This is particularly
important with straight run ducts.
b. When thermometer readings stabilize, subtract
return-air temperature from supply-air temperature to
determine temperature rise.
If the temperature rise is outside this range, check the following:
a. Gas input for low-and high gas heat operation.
b. Derate for altitude if applicable.
c. Return and supply ducts for excessive restrictions
causing static pressures greater than 0.50-IN. W.C..
d. Adjust temperature rise by adjusting blower speed.
Increase blower speed to reduce temperature rise.
Decrease blower speed to increase temperature rise.
ELECTRICAL SHOCK HAZARD
Failure to follow this warning could result in personal injury
or death.
Disconnect 115-v electrical power before changing speed tap.
!
WARNING
For low-heat, the following connections can be made at LO-HT
on control:
a. Speed 2 (Orange)
b. Speed 1 (Red) -- Factory Setting
