Installation (cont.)

GAS AND ELECTRICAL SUPPLY OPENINGS

Holes must be drilled for the gas line (and electrical supply if you use an optional Blower Kit). Drill a 1-1/2 inch hole in wall for gas line where indicated on cardboard template or refer to Fig. 3, page 7. You will have to determine whether the gas line will enter the home through the outside wall or wall floor plate. These

instructions can only guide you in where the gas line will enter the furnace.

IMPORTANT

For walls more than 9 inches thick, read note below.

NOTE

(Refer to Fig.5.) The vent tube "C" and air inlet tube "D"

are factory installed for walls up to 9 inches thick only. For walt thicknesses up to 24 inches, follow the instructions packed with the appropriate factory built VENT EXTEN- SION KIT. See OPTIONAL ACCESSORIES on page 3.

FURNACE MOUNTING

Set the furnace body against the wall, legs on the floor,

with the vent tubes ("C" and "D" Fig. 5) extending through the spacer plate.

Fasten the furnace to the wall through holes at the top and bottom of the support legs using four (4) #8 roundhead (long) screws ("F" Fig. 5) provided.

Push the air inlet shield "J" on from the exterior side of wall. Rotate the air inlet shield until notches on the end of the tube are straddling the standoff tabs on the mount- ing spacer plate "A". Trim the air inlet shield "J" flush with the exterior of the wall.

The gas line can be run at this time or done after the furnace is mount- ed. See section GAS SUPPLY and PIPING, page 10.

No electric power is required unless

furnace is equipped with an optional blower kit.

Do not connect 115V service line to the gas valve or wall thermostat.

Fig. 5) with spacers entering and centered within the 9-114 inch vent

opening in wall. Level top of spacer plate (embossed top) and fasten to in-

terior wall using six (6) #8 roundhead (long) screws ("B" Fig. 5) provided.
