Attached to (Surface Mount) an inside or outside wall.

A. You need Vent Shield Kit, Stock No. 42-7311

(sold separately) for surface mounting.

2. Installed to vent vertically, or horizontally into on existing chimney.

A. To vent horizontal¥ use Horizontal Vent Kit

Stock No. 42-7369 (sold separately). This kit will require five inch type B-I (round _doub)e

w,alt) vent pipe (sold separately) leadlng

from it to the chimney.

B. To vent vertically, use type BW (oval double

wall) gas vent pipe and fittings. Sears gas vent

kit, Stock No. 42-99767, may be used.

3. Installed with a rear wall register (optional accessory kit). If it is to be used, follow instruc- tions with the kit. Cut opening in rear wall for

Consider the following points before attempting to

Combustion Air

WARNING

I E SURE TO PROVIDE ENOUGH FRESH AIR FOR

COMBUSTION AND VENTILATION.

outside air must enter the house to replace that used by the burner.

Homes usually have enough leakage around doors and windows to provide all the air needed.

If the furnace is installed in on unusually tight.home (with well fitting =term window; and doors, weather

stripping, cracks caulked, etc.) fresh air must be

brought in from the outside through a permanent opening at least 13 square inches in free area.

Comply =with ANSI standard 7.223.1-1974 "The . National Fuel Gas Code", and with your local codes

and ordinances, m

Surface Mount Installation

(FOR RECESSED MOUNT INSTALLATION, TURN TO PAGE 9)

For ease of installation, servicing and cleaning, install the furnace at least four (4) inches above the

floor (Fig. 2).

FIND THE STUDS

Use a stud tocator or four 8 penny finishing nails. Repeatedly drive and remove a nail into the wall in

the area of the stud until it is located. Then find one side. Leave the nail at this location. Drive another

nail just on the other side of the same stud. The

other stud should be about 16 inches from the one found. Drive finishing nails on both sides of this stud.

Draw centerline on walt for each stud (Fig. 3).

within 10 feet, There must be at least 1 inch clearance between the vent pipe and any combusti-

ble material.

If an existing brick chimney is used, follow the directions above for the section from the base plate

through the ceiling. Then you may adapt to a Type B-1,4" round, double wall pipe for the horizontal run

to the chimney. Connect into a chimney only in accordance with local codes and ordinances.

INSTALL VENT SHIELD

The vent shield is 35-t/8 inches long. Measure from top of furnace to ceiling. Cut the vent shield to this

dimension less 1/8 inch. Be sure to cut from the top (end opposite flange) (Fig. 11).

Place vent shield on top of furnace and against the wall. Drill holes in the furnace top through holes in

vent shield. Fasten to furnace with sheet metal screws. Screw sides to wall,
