Cleaning or Replacing Flue Pipes | Thermo Products ome-72d36

All installations and services must be performed by qualified service personnel.

D. CLEANING OR REPLACING FLUE PIPES

Flue pipes should be inspected during the annual maintenance check-up or during each subsequent service call.

Check all flue pipes for restrictions due to soot, or carbon build-up, as well as foreign matter, or any materials, that cause the venting system to restrict the proper venting of combustion products. If a restriction is found, the flue pipe must be cleaned or replaced to ensure proper venting.

Flue 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 flue pipe must be replaced with a properly sized, agency-approved, flue pipe.

E. 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 fuel supply shutoff valve(s).

2.Turn the furnace power switch “off” and disconnect electrical power to the unit.

3.Fill the oil tank to prevent condensation (oil units only).

4.If shutdown exceeds one season, an oil stabilizer should be added to the oil tank as recommended by your oil supplier (oil units only).

ON START-UP:

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

2.Check for a clean, adequate supply of fuel.

3.Set the room thermostat above room temperature.

4.Open all shutoff valves in the fuel supply line.

5.Turn “on” the main power at the disconnecting switch and at the furnace power switch to start the burner. If the burner does not start, immediately reset the burner primary (ignition) control module. On oil furnaces, if required, vent the fuel of air as soon as the burner motor starts. If the burner stops during venting, wait three to five minutes before attempting to restart.
