SECTION 6 • PROPER MAINTENANCE OF YOUR FURNACE
You need special abilities, mechanical skills and tools to maintain your furnace properly. If you are uncertain about your abilities or if you lack proper skills or tools, do not try to maintain or repair you furnace yourself. Instead, contact a qualified installer, service agency or gas supplier.
6.A IF YOU SMELL GAS OR ANY UNFAMILIAR SMELL WHILE WORKING ON YOUR FURNACE:
1.Do not try to light main burners.
2.Do not touch or turn on any electrical switch.
3.Do not use any phone in your building.
4.Immediately call your gas supplier from a neighbor’s phone. Follow gas supplier’s instructions.
5.If you cannot reach your gas supplier, call fire department.
6.B LUBRICATION REQUIREMENTS
The main blower motor and the induced draft blower motor are permanently lubricated, and no maintenance is required.
6.C MAKE SURE AIR FILTER(S) IS IN PLACE
Ask your installer, local qualified service technician or gas supplier to make sure your filter(s) is in place properly. Become familiar with its location and procedures for removing, cleaning and replacing it.
Recommended filter sizes are shown below.
MAIN SYSTEM FILTER: 20 X 30 X 1 Fiberglass disposable
FRESH AIR FILTER: | 4 x 26 x 1/2 |
| Washable |
See Figure 3 for filter locations.
WARNING
Operating furnace without clean air filter(s) can damage blower motor, heat exchanger or air conditioning system components. This can cause system failure which could result in damage or injury.
6.D KEEP AIR FILTER(S) CLEAN
As a user, your personal responsibility is to keep air filter(s) clean.
CAUTION
A dirty air filter(s) reduces system efficiency and can cause erratic control performance. These could result in damage to blower motor or heat exchanger.
1.During the first four weeks after your furnace is installed, inspect your air filter(s) for dirt every week. Then check the filters monthly and clean as necessary.
2.If the filter(s) is of a washable type, clean filter(s) according to the manufacturer’s specifications.
WARNING
After cleaning or changing filter(s), filter access cover(s) must be replaced. Failure to do so could cause nausea, asphyxiation, or fire resulting in damage, injury or death.
6.E DO NOT OBSTRUCT DUCT WORK
For proper operation, keep registers and return air grilles open. Do not cover or block them with rugs, carpets, drapes or furniture.
6.F HAVE YOUR FURNACE CHECKED ANNUALLY
The furnace, vent terminal, and the combustion air intake hood should be inspected yearly by a qualified service agency, generally prior to the heating season. Detailed procedures for this inspection are contained in the instructions booklet and should be handled by the qualified service agency only.
A general inspection of the furnace, the furnace area and the vent terminal should be conducted on a regular basis by the owner/occupant. This review should include:
1.Make sure the furnace always has the minimum clearance as detailed on the furnace rating plate. Special attention must be given to these items if any remodeling is done.
2.Make sure the vent terminal is in place and is physically sound.
