MAINTENANCE
1. Motor: Inspect the motor once a year - motor should rotate freely. To prolong the life of the motor, it must be
lubricated with six drops of SWG Superlube, Part # 46226200, annually.
2. Wheel: Inspect the power vent wheel annually to clear any soot, ash or coating which inhibits either rotation or air
flow. Remove all foreign materials before operating.
3. Vent System: Inspect all vent connections annually for looseness, for evidence of corrosion, build up of soot and
for flue gas leakage. Replace, seal or tighten pipe connections if necessary. Check the power vent choke plate to
insure it is secured in place. Check the barometric draft control, if installed, to insure the gate swings freely.
4. System Safety Devices: With the heating system operating, disconnect the pressure sensing tube from the
pressure switch. This will stop the burner feed operation. Re-connecting the tube will restart the burner feed
system.

NSTALLATION
1. Align holes in the circular cover plate with holes in the motor mount bracket on
the motor assembly. (See Figure 15)
2. Slide motor assembly onto protruding threaded studs on the power vent body.
The exhaust chute must be pointing downward. Replace the four nuts securely to
the threaded studs. (See Figure 16)
3. Re-attach flexible conduit and wires to motor and secure cover on the electrical
box.
4. Install motor cover with the side louvers pointing downward.
CAUTION
Avoid applying excess pressure on the blower wheel when
cleaning off any build-up of material. This will cause an imbalance of the blower
wheel which results in excessive vibration and premature motor failure.
