combustion products.  If a restriction is found, the flue vent 

must

 be cleaned or 

replaced to ensure proper venting. 
 
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. 
 
 

H.  EXTENDED SHUTDOWN 

 
If this furnace is shut down or off for an extended period of time, several steps can be 
taken to help insure a smooth and reliable start. 
 

ON SHUT DOWN: 

 

1.  Close the gas supply shutoff valve(s).  
2.  Turn the furnace power switch “off” and disconnect electrical power to the unit. 

 

ON START-UP: 

 

1.   Have the heating system (and furnace) inspected and started by a qualified 

service person.

 

2.  Set the room thermostat above room temperature.
