Installation

Furnace location

Before you start!

It is very important you check with your dealer, local fire department, or building inspector. They will be able to in- form you of any state or local codes pertaining to the loca- tion and installation of your furnace.

The ideal location for your furnace is centrally located in the basement. This allows for an even heat distribution by having all the duct work approximately the same length. Ideal locations cannot always be used for one reason or another, therefore, let's look at some alternatives.

If your home does not have a basement, but a utility room or garage, make sure there is enough space to maintain the required clearances stated on the label located on the furnace. Also, read about combustion air.

INSTALLATION#1

With this installation, a back draft damper (optional) is in- serted into the heat run before the plenum of the existing furnace to prevent air from the existing furnace to blow back into the furnace when it is not in use. When a back damper is employed, it should be located as close to the existing furnace plenum as practical.

Chimney location is also critical. The furnace must be placed as close as possible to the chimney. You want the chimney connector (smoke pipe) to have a minimum of elbows, two (2) or less. Also, the chimney connector should not have to run more than six (6) feet to the chimney.

CAUTION: The warm-air supply outlet of the Fur- nace should not be connected to the cold-air re- turn inlet of the central furnace because a possibil- ity exists of components of the central furnace over- heating and causing the central furnace to operate other than as intended.

After installation, be sure the measured external static pres- sure of the central and Furnace is not greater than those marked on the nameplates.

INSTALLATION#2

Extending the hot air duct from the furnace into the exist- ing plenum will help direct the flow of air from the furnace as well as the flow in the existing furnace. Ducting enter- ing the existing plenum at an angle (approximately 45 de- grees) will facilitate air flow from the furnace while divert- ing air from the existing furnace.

The baffle on this system should be made the full width of the furnace plenum in order to properly direct the air into the distribution ducts.
