Burners

To clean the burners, first remove them from the furnace as explained in Burner Instructions on page 9. Vacuum and/or brush as required.

Vent Outlet

Visually inspect vent outlet periodically to make sure that there is no buildup of soot or dirt. If necessary, clean to maintain adequate opening to discharge flue products.

Heat Exchanger

With proper combustion adjustment, the heat exchanger of a gas-fired furnace will seldom need cleaning. Sooting of a gas appliance is highly irregular and once cleaned, the cause of the sooting must be determined. If the heat exchanger should become sooted, it can be cleaned as follows:

1.Remove the burner assembly as outlined in Burner Instructions on page 9.

2.Remove the combustion blower.

3.At the bottom of the heating section, remove the screws holding the flue collector box. Carefully remove the flue collector box without ripping the adjacent insulation.

4.Using a wire brush on a flexible wand, brush out the inside of each heat exchanger from the burner inlet and flue outlet ends.

5.Brush out the inside of the flue collector box.

6.Run the wire brush down the heat exchanger tubes from the flue collector end.

7.If soot buildup is excessive, remove the vent motor and clean the wheel and housing. Run the wire brush down the flue extension at the outlet of the vent housing.

8.After brushing is complete, blow all brushed areas with air. Vacuum as needed.

9.Replace parts in the reverse order they were removed in Steps 1 through 3.

10.When replacing the flue collector box, be careful so as not to tear the adjoining insulation.

11.Assure that all joints on the vent side of the combustion system are air tight. Apply a high temperature (+500°F) sealing compound where needed.
