Gaskets/Sealing Materials; Heat Exchanger; House Air Blower; Extended Shutdown - Thermo Pride GMD1-60N Installation And Service Manual

All installations and services must be performed by qualified service personnel.
Vent pipes should also be inspected for any signs of corrosion, deterioration, or leakage
that may cause combustion by-products to infiltrate the home or indoor environment.
If signs of corrosion, deterioration, or leakage are evident, the vent pipe must be
replaced with a properly sized, agency-approved, vent pipe.
E. GASKETS/SEALING MATERIALS
Inspect all visible gaskets for signs of degradation, especially any seals which were
removed as part of the inspection. Replace any suspect gaskets.
F. HEAT EXCHANGER
Inspect for corrosion, pitting, warpage, deterioration, carbon build-up, and loose gaskets
in the flue pipe, burner box, and accessible areas of the heat exchanger.
G. HOUSE AIR BLOWER
Check and clean the blower wheel, housing, and compartment with a vacuum. Check
the motor nameplate and follow the motor manufacturers instructions for lubrication, if
required.
IMPORTANT: Some motors are permanently lubricated and should not be oiled.
See motor nameplate for specific instructions.
