MAINTENANCE
NORMAL MAINTENANCE
CAUTION: Prior to any of the following maintenance proce- dures, shut off all power to the unit to prevent per- sonal injury.
Periodic maintenance normally consists of changing or cleaning filters and (under some conditions) cleaning the main burners.
FILTERS - Inspect once a month. Replace disposable or clean permanent type as necessary. DO NOT replace permanent type with disposable.
MOTORS - Indoor fan and outdoor fan motors are permanently lubricated and require no maintenance. Ventor motor is factory lubricated for an estimated 10 year life.
OUTDOOR COIL - Dirt should not be allowed to accumulate on the outdoor coil surface or other parts in the air circuit. Cleaning should be as often as necessary to keep coil clean. Use a brush, vacuum cleaner attachment, or other suitable means. If water is used to clean coil, be sure power to the unit is shut off prior to cleaning.
NOTE: Exercise care when cleaning the coil so that the coil fins are not damaged.
Do not permit the outdoor air discharge to be ob- structed by overhanging structures of shrubs.
BURNER & PILOT - Periodically (at least annually at the beginning of each heating season) make a visual check of the pilot and main burner flame. If necessary, adjust main burner primary air shutters so that no yellow flame is observed as explained under “BURNER AIR SHUTTER ADJUSTMENT”. If it is not possible to adjust for the proper flame, the burners may need cleaning.
TO CLEAN BURNERS - Remove them from the furnace as explained in “Burner Instructions”. Clean burners with hot water applied along top of the burner.
COMBUSTION AIR DISCHARGE - Visually inspect discharge outlet periodically to make sure that the buildup of soot and dirt is not excessive. If necessary, clean to maintain adequate combustion air discharge.
The manufacture recommends that the furnace system be inspected once a year by a qualified service person.
CLEANING FLUE PASSAGES AND HEATING ELEMENTS
With proper combustion adjustment the heating element of a gas fired furnace will seldom need cleaning. If the element should become sooted, it can be cleaned as follows:
1.Remove the burner assembly as outlined in “BURNER IN-
STRUCTIONS”.
2.Remove the roof over the gas heat section.
3.At the top front of the heat section, remove the screws hold- ing the top of the flue collector box. Carefully remove the top of the flue collector box without ripping the adjacent in- sulation.
4.Lift out the flue diverter baffle.
5.On the inside of the flue collector box, remove the screws holding the flue baffle. Remove the flue baffle.
6.Using a wire brush on a flexible wand, brush out the inside of each heat exchanger from the burner inlet and flue outlet ends.
7.Brush out the inside of the flue collector box and the flue baffles.
8.Run the wire brush down the vent tube from the flue collec- tor end.
9.If soot
10.After brushing is complete, blow all brushed areas with air or nitrogen. Vacuum as needed.
11.Replace parts in the order they were removed in Steps 1 to 5.
12.When replacing the top of the flue collector box, be careful so as not to tear the adjoining insulation.
13.Assure that all seams on the vent side of the combustion system are air tight. Apply a high temperature (+500°F) sealing compound where needed.
