SECTION X: MAINTENANCE
The following maintenance should be performed by a qualified service technician at the minimum periodic interval listed
below.
1. Bi-annually, oil the induced draft motor in the ports of the front and rear motor bearings with 4 drops each of SAE 20
motor oil.
2. Annually, inspect the blower wheel for debris and clean as necessary.
3. Inspect the venting system for corrosion and leaks. Replace any defective sections of vent pipe.
4. Inspect the blower vent damper for proper movement, making sure the damper extends to the full open position after
the blower reaches full speed (see Figure 5). If the damper blade does not fully open, remove the vent connector and
make sure the blower wheel is clean and debris has not fallen on the damper blade or blower wheel. If the damper
binds, replace the blower assembly. DO NOT ATTEMPT TO REPAIR THE DAMPER!
