Locating Wall Furnace (cont.)

MODELS 1403622, 1403621, 2203622, 2203621, 3003622 and 3003621

(All other models have a built-in thermostat)

Choose a location for the thermostat about 5 feet above the floor on an inside wall. The thermostat wire supplied with your furnace is 20 feet long, which should be enough to run up through the attic so the thermostat can be a max- imum of 16 feet from furnace measured in a straight line,

or approximately 12 feet from the furnace if the wire is run under the floor. The thermostat should be sensing average

room temperature, avoid the following:

After picking a location that meets the requirements, in- spect the wall, floor and outside areas. Make sure there are no pipes, wiring, or anything else that would interfere with furnace or vent or thermostat installation. If required, move them or pick a new location.

Installation

BEFORE YOU BEGIN: To avoid electrical shock turn off electrical circuits that pass through the wall where you are going to install the furnace.

This furnace must be installed using only the vent tube, air inlet tube and vent cap assembly supplied by the manufacturer.

Before the furnace is installed an opening must be cut through the wall for the vent cap.

FIND THE STUDS

Find the studs where the furnace is to be placed. Use a stud Iocator or small finishing nails. Repeatedly drive and remove a nail into the wall in the area of the stud until you find it. Then find one side. Leave the nail there. Drive another nail just on the other side of the same stud.

The inside edge of the other stud should be about 14-1/2 inches from the one found. Drive a finishing nail on the inside edge of this stud, then another nail on the outside edge.

Using a level, draw vertical lines that will represent the two stud center lines.

CUT VENT OPENING

After locating studs, use the cardboard template (Fig. 4, page 8). Line up the CENTER OF STUD lines on the template with the center lines you have drawn on the wall. Use the template to draw the 9-1/4 inch diameter circle on the wall. Then mark the location of the gas supply line.

Using a window, door or wall corner for reference, measure to find where vent will be on outside wall. Check to be sure

of proper clearances (Figs. 1 and 2, page 6). If necessary, relocate for proper clearances.

Drill a 1/4 inch hole in the wall at the vent opening center mark all the way through to the outside. Cut the 9-1/4 inch diameter hole through inside wall. Using the 1/4 inch hole as center, cut a matching hole in outside wall. It may be petter to work from the outside when breaking through brick, stone or tile.

Make sure the inside and outside wall openings are aligned so tubes and vent will fit properly.

IN NEW CONSTRUCTION frame in 9-1/4 inch x 9-1/4 inch opening centered between studs spaced 16 inches on center, and center point located as noted per Fig. 3.
