!WARNING

ELECTRICAL SHOCK HAZARD

Failure to follow this warning could result in personal injury or death.

Turn off electrical power to furnace before performing any maintenance or removing panels or doors.

Air Filters/Monthly

2.Have someone check the structure frequently during cold weather to make sure it is warm enough to prevent pipes from freezing. Instruct them to call a qualified service agency to call to provide service, if required.

3.Install a reliable remote sensing device that will notify somebody of freezing conditions within the home.

Winter Shutdown (90+ Furnaces)

If you go away during the winter months and do not leave the heat on in your home, the plastic transition box and the condensate trap on the furnace must be protected from freeze damage. (See Fig. 2)

1.Disconnect the 1/2” I.D. rubber hose from the vent drain fit- ting (or tee) that is located downstream of the combustion blower. Insert a funnel into the hose and pour four (4) ounces of sanitary type (RV) antifreeze into the condensate trap. Reconnect the 1/2” I.D. rubber hose to the stub on the vent drain fitting. Secure with the hose clamp.

2.Disconnect the 5/8” I.D. rubber hose from the condensate trap. Insert a funnel into the hose and pour four (4) ounces of sanitary type (RV) antifreeze into the plastic transition box. Squeeze the hose together near the end and quickly re- connect the 5/8” I.D. rubber hose to the stub on the con- densate trap. Secure with the hose clamp.

3.When you return home, your furnace will be ready to start, as it is not necessary to drain the antifreeze from the furnace.

Furnace Maintenance

Have your furnace inspected and serviced on an annual basis (before the heating season) by a qualified service agency.

Labeling

!WARNING

FIRE OR EXPLOSION HAZARD

Failure to follow this warning could result in personal injury or death.

Label all wires prior to disconnection when servicing controls. Verify proper operation after servicing. Only qualified service agencies should attempt electrical service.

The air filter(s) should be inspected at least monthly and cleaned or replaced as required. There are many types of filters that are commonly used. Washable filters (constructed of aluminum mesh, foam, or reinforced fibers) may be cleaned by soaking in mild detergent and rinsing with water. The fiberglass disposable type should be REPLACED before it becomes clogged. Other filter types should be serviced in accordance with the manufacturer’s recommendations.

Remember that dirty filters are the most common cause of inadequate heating or cooling performance.

Replacement Filters

If the filter is not located at or within the furnace, it should be located somewhere in the return-air duct system.

The recommended sizes and types of filters that may be used with your furnace are based on the furnace’s heating gas input rate (and cooling system capacity, if so equipped).

Replacement filters should be of the same type and size as the original filters, to ensure adequate air flow and filtering. A disposable low velocity filter can be replaced with a washable high velocity type. Do not replace a high velocity filter with a disposable low velocity filter, except as permitted below.

If a cleanable (high-velocity) filter(s) is to be replaced with a disposable (low-velocity) filter(s), the airflow area of the filter(s) must be doubled (i.e., a second filter of the same size must be installed so that only half of the air goes through each filter). A second return-air duct to the furnace may be required in which to install the second filter. Modification of a furnace installation shall comply with the local installation code and the furnace installation instructions, and shall be made only by a Qualified Service Agency.

NOTE: Some filters are marked with an arrow to indicate the proper direction of air flow through the filter. The air flow direction will be towards the blower motor. Make sure filter is installed correctly.

NOTE: Some units are equipped with filter rack.

Filter Replacement - Upflow

The filter may be installed inside the bottom of the furnace blower compartment, or the filter(s) rack may be installed under the furnace or on either or both sides of the furnace. A plastic end cap(s) is inserted in the filter rack(s) after the filter(s) is installed. The end cap keeps air from escaping around the open end of the filter rack. See Fig. 4 and Fig. 5 for side and bottom locations. Rack end cap is similar for bottom mounted filter rack.
