1. Close the fuel supply valve to the heater and

disconnect the electrical supply before servicing

unless necessary for your service procedure.

2. Clean the heater’s orifices with compressed air or a

soft, dry rag. Do not use files, drills, broaches, etc. to

clean the orifice hole. Doing so will enlarge the hole,

causing combustion or ignition problems. Replace

the orifice if it cannot be cleaned properly.

3. The high limit switches, air proving switch, and

thermostat can be tested by disconnecting the leads

at the component, and placing a jumper connecting

the leads together.:

-- Reconnect the electrical supply and open fuel

supply valves.

-- If the heater lights, the component is defective

and must be replaced.

-- Do not leave the jumper on or operate the heater if

the part is defective. Replace the part immediately.

-- An alternate method for checking the components

is to perform a continuity check..

4. Open the respective access panel for servicing of

burner, gas control, or fan related components.

5. Disconnect the appropriate electrical leads for the

component being serviced.

6. For reassembly, reverse the respective service

procedure. Ensure gas connections are tightened

securely.

7. After servicing, start the heater to ensure proper

operation and check for gas leaks.
