INSTALLATION

(Continued)

6.Attach thermostat to thermostat mount- ing plate with screws provided (see Fig- ure 4). IMPORTANT: Note mounting plate position in Figure 4. Correctly position mounting plate for your model furnace.

7.Insert thermostat mounting plate be- tween wall and cabinet flange. Line up top notch on mounting plate with top screw on flange (see Figure 5). IMPORTANT: Thermostat for 25,000 BTU/Hr model mounts on right side of furnace (see Figure 5). Thermostat for 40,000 BTU/Hr model mounts on left side of furnace (see Figure 5).

8.Insert screw in cabinet flange and ther- mostat mounting plate and tighten firmly.

IMPORTANT: Make sure thermostat wires do not touch combustion chamber.

1.Locate thermostat 4 1/2 to 5 feet above the floor on an inside wall away from any heat sources. The thermostat needs to sense average room temperature. Avoid the following:

HOT SPOTS

Concealed pipes or ducts Fireplaces

Registers

TV sets and radios Lamps or direct sunlight Kitchen

COLD SPOTS

Concealed pipes or ducts Stairwells (drafts) or doors (drafts) Unheated rooms on other side of wall

DEAD SPOTS

Behind doors Corners and alcoves

2.Before installing thermostat, inspect the wall, floor, and attic areas. Make sure there are no pipes, wiring, or anything else that would interfere with install- ing thermostat. Do not mount thermo- stat to stud. If there are any obstruc- tions, choose a new location.

3.Provide two 18-gauge insulated stranded wires for the thermostat wire. Also pro- vide two wire nuts, and two wall anchors. There is a red and a white thermostat wire coming from the furnace. The extra ther- mostat wires you furnish attach to these wires. Make sure you furnish a red and a white wire. This will insure correct hookup. Purchase enough thermostat wire to go from the furnace to the thermostat location. Do not cut and splice this wire. The thermostat wire must be unbroken.

Routing Thermostat Cable

All wiring must meet local codes. The fol- lowing instructions cover routing the wire through the attic. You can run wiring from a basement or crawl space.

1.Unplug furnace.

2.Before drilling hole in wall, drive a small finishing nail through ceiling directly above thermostat location. Pull nail out and push a small stiff wire through hole. This helps you locate thermostat mount- ing location when in attic.

3.In attic, locate stiff wire. Drill 1/2" hole in center of ceiling wall plate next to stiff wire. Remove wire.

4.Probe through drilled hole in wall plate with a stiff wire to make sure there are no pipes, wiring, or anything else blocking the way for thermostat wires. If you find blockage, choose new loca- tion for thermostat.

5.Drill a 1/2" hole through the wall at thermostat mounting location.

6.From attic, feed thermostat wires through hole in ceiling plate until wires reach thermostat location.

7.Make a small hook with a piece of stiff wire. Run wire hook through 1/2" hole in wall. Hook thermostat wires. Pull wires through hole in wall. Make sure 6" of wires stick out.

8.Drive a small finishing nail in ceiling above furnace.

25,000 BTU/Hr Model - Drive nail above right side of furnace.

40,000 BTU/Hr Model - Drive nail above left side of furnace. Pull nail out and push a small stiff wire through hole. This helps you locate wire routing location when in attic.

9.Repeat steps 3 and 4 above.
