FILTER LOCATION AND CLEANING 

c

 CAUTION: To avoid injury from moving part, hot 

surfaces or electrical shock, shut off the power to 
the furnace and allow the furnace to cool before 
removing furnace access door to service filter. 

 

The air filter should be inspected each month and 
replaced when dirty. Replacing the air filter frequently 
may prevent airborne contaminants from going through 
the furnace and depositing in the furnace, duct system, 
and interior of the building.   

 

See Figure 9 for the location of the return air filter.

  

 

 

 
 
COMPONENT LOCATIONS 

The following diagram shows a typical furnace 
installation and typical position of the components 
referenced in these instructions

INSPECTION AREAS 

IMPORTANT:   For safe operation it is the 
responsibility of the owner and/or user that the 
burner, chimney/vent pipe, heat exchanger and 
controls should be inspected every year by a 
qualified heating contractor. 

 

     VESTIBULE:  The furnace vestibule areas or burner 

compartment should be inspected by removing front 
door of the furnace and looking for signs of excessive 
heat such as discoloration of components, materials 
damaged from rust or corrosion, soot or carbon build-
up. 

  

     EXTERIOR OF FURNACES: The furnace exterior 

should be inspected for signs of excessive heat such 
as discoloration of materials or damage from rust or 
corrosion. 

 

     VENT CONNECTOR: The furnace vent pipe should be 

inspected for signs of rust, corrosion pitting, or holes 
in the pipe.  Check for leakage around seams in pipe 
indicated by soot or condensate streaks.  

 

     ROOF JACKS: The furnace roof jack should be 

inspected for signs of rust or corrosion, pitting or 
holes, signs of excessive condensation or moisture 
leaking from roof jack. 

 

 

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 up. 

 

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. 

3. 

Open all shutoff valves in the gas supply line. 

4. 

Turn “on” the main power at the 
disconnecting switch and at the furnace 
power switch to start the inducer. 

5. 

Follow the “BURNER OPERATION AND 
ADJUSTMENT” procedure in Section K.
