DUCT WORK AND BLOWER SPEED ADJUSTMENT
Supply and return duct system should be sized properly
for efficient operation. Normal air temperature rise
through the furnace should be adjusted to
approximately 80-90º F. Proper blower speed
adjustment, in conjunction with adequate duct work are
necessary to achieve this.
A high temperature rise will result in excessive fuel
usage. This is due to the high stack temperature that
always accompanies a high air temperature rise. It can
also cause premature heat exchanger failure.
To perform temperature rise check, start furnace and let
it run a minimum of 10 minutes. (Be sure all duct work
is complete and furnace is in its normal operating
condition). Place #1 thermometer in the return duct
near the furnace. Place #2 thermometer in the supply
duct near the furnace, but not in the plenum.
After
10 minutes or more operation, take thermometer
readings. Supply air temperature should be no more
than 80-90º higher than return air temperature.
Air temperature rise can be lowered by:
1. Increasing blower speed.
2. Additional supply or return outlets.
3. Lowering firing rate.
