Installation
Locating Wall Furnace
Consider the following points before attempting to install the furnace.
All Models
1. This is a direct-vent wall furnace. It must be installed on an outside wall for proper venting of flue gases. (Figure 1).
2. Wall furnace must be surface mounted on an outside wall up to 24-inches thick when using an optional Vent Extension Kit.
3. Check the clearances needed from the furnace and vent. (Figure 1 and 2). You must place the furnace where you will have no less than the clearances shown.
4. The outside vent must be at least 18-inches away from any window or other building opening.
5. The furnace will not work if anything stops free entry of fresh air into the vent, or free flow of flue gases from it. Be sure the center of the vent cap is at least 12-inches above ground level or shrubs. (Figure 1). Make sure shrubs are kept trimmed. It must also be at least 18-inches from any wall or other blockage and 30-inches below any overhang.
6. Place the furnace near the center of the space to be heated for good air circulation. Do not put it behind a door or draperies. Do not put it in a closet, alcove, hallway or other confined space where the furnace could be isolated by closing doors to the heated space.
7. Be sure that gas piping and electrical wiring (optional blower only) can be brought to the furnace.
8. Select a location that will provide adequate accessibility clearance for servicing and proper operation.
Interior Clearances (Figure 2). 14036 Series:
1. There must be at least 1-3/16 inches of space between the floor (top of floor covering) and the bottom of cabinet.
2. The top of the furnace must be at least 18-inches from the ceiling or other projecting overhang.
Choose a location for the thermostat about 5-feet above 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 maximum 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 an average room temperature; avoid the following:
Hot Spots Cold Spots Dead Spots
Concealed pipes/ducts Concealed pipes/ducts Behind doors
Fireplaces Stairwells (drafts) Corners/alcoves
Registers Doors (drafts)
TV sets Unheated rooms on
Radios other side of the wall
Lamps
Direct sunlight
Kitchen
After selecting a location that meets the requirements, inspect the wall, floor and outside areas. Make sure there are no pipes, wiring, or anything else that would interfere with furnace, vent or thermostat installation. If required, move or pick a new location.
FIGURE 1
3. The side of the furnace must not be closer than 2-inches to an adjacent wall.
22036 / 30036 Series:
1. There must be at least 5-1/2 inches of space between the floor (top of floor covering) and the bottom of cabinet.
2. The top of the furnace must be at least 24-inches from the ceiling or other projecting overhang.
3. The side of the furnace must not be closer than 2-inches to an adjacent wall.

Installation
FIGURE 2
MOUNTING LEGS
DO NOT USE FLUE TUBES TO SUPPORT WEIGHT OF FURNACE
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 the inside wall. Using the 1/4 inch hole as center, cut a matching hole in the outside wall. It may be better to work from the outside when breaking through brick, stone or tile.
Make sure the wall openings are aligned so vent tubes and vent will fit properly.
In new construction, frame in 9-1/4 inch x 9-1/4 inch opening centered between the studs spaced 16 inches on centre and the center point located as noted in Figure 3.
FIGURE 3
To avoid electrical shock, turn off all 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 locator or small finishing nails. Drive a nail on the inside of the first stud. Drive a second nail on the outside of this stud.
The inside edge of the next 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 the studs, use the cardboard template (Figure 4). Line up the center of the 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 the vent will be on the outside wall. Check to be sure of the proper clearances (Figures 1 and 2). If necessary, relocate the furnace for proper clearances.
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 the wall for the gas line where indicated on the cardboard template. (Figure 4). You will have to determine whether the gas line will enter the home through the outside wall or the floor plate. These instructions can only guide you to where the gas line will enter the furnace.
Installation
FIGURE 4
The gas line can be run at this time or after the furnace is mounted. See "'Gas Supply and Piping" section.
No electrical power is required unless furnace is equipped with an optional blower kit.
Do not connect a 115V service line to the gas valve or wall thermostat.
Install Spacer Plate (Figure 5)
Install the mounting spacer plate with spacers entering and centered within the 9-1/4 inch vent opening in the wall. Level the top of the spacer plate (embossed top) and fasten it to the interior wall using the six (6) #8 roundheaded (long) screws provided.
Important: The vent tubes are factory equipped for walls 5 to 9
inches thick only. For wall thicknesses up to 24 inches, follow the instructions packed with the appropriate factory Vent Extension Kits.
Furnace Mounting (Figure 5)
Set the furnace body against the wall, legs on the floor, with the vent tubes extending through the spacer plate.
Fasten the furnace to the wall through holes at the top and bottom of the support legs using the four (4) #3 round headed (long) screws provided.
Push the air inlet shield on from the exterior side of the wall. Rotate the air inlet shield until the notches on the end of the tube are straddling the standoff tabs on the mounting spacer plate. Trim the air inlet shield flush with the exterior of the wall. Never crimp the vent tubes or force them to fit.
Note: Do not trim flue extension or air inlet collar. Install Vent Cap
Outside, place a single strip of mastic (provided) around the back flange of the vent cap. (Figure 5). Install the vent cap by inserting it into the air inlet tube and over the vent tube.
Important: The top of the vent cap is embossed "TOP". Install
it in the correct position to prevent water from entering the wall. Level the vent cap and attach it to the outside wall with four (4) #8 roundheaded (long) screws. (Figure 6).
If the wall surface is not flat (shiplapped siding, etc.) or less than 5 inches thick, use a Thin Wall Collar Kit (9307) or, build up a flat surface with wood strips. Do not tilt or bend the cap to fit uneven surfaces. The vent cap flange must be tight against the wall to prevent rain or wind penetration. Use standard caulking compound if required (not provided).
For brick, masonry or plaster walls, it may be necessary to use lag screws or expanding anchor bolts, which are not furnished with the furnace.
When the vent cap is to be installed on vinyl siding, or a projection within 6 inches of any side that could block the air inlet, the entire vent should be supported away from the wall at least the distance of the projection. A 2" x 4" frame, with outside dimensions that match the overall dimensions of the mounting plate, is recommended. The 2" x 4" frame protects vinyl siding from possible damage. Seat and paint all joints. The wall depth plus the additional 2" x 4" frame depth should not exceed a total depth of 13 inches.
