Locating Wall Heater and Thermostat (sold separately)
Consider the following points before attempting to install the heater:

1. Heater may be surface-mounted or recessed on any interior or exterior wall if you are not using the optional rear outlet.

2. If you are using the optional rear outlet, you must install on an interior wall.

3. Maximum depth of recess is 5-3/8 inches.

4. Check the clearances needed. The side of the heater must be at least 6-inches from a corner or wall divider (Figure 2).

5. Try to place the heater near the center of the space to be heated for good air circulation. Do not install where a door or draperies could swing over heater or optional rear outlet. Do not put in a closet, alcove, hallway or other confined space.

6. Be sure that electrical wiring can be brought to the heater.

7. To provide adequate clearance and service access, the front of the heater must face the open room.

8. Choose a location for the thermostat (sold separately) about 5-feet above the floor on an inside wall. The thermostat wire supplied with your heater is 13 feet long, which should be enough to run up through the attic so the thermostat can be a maximum of 16 feet from heater measured in a straight line, or approximately 12 feet from the heater if the wire is run under the floor. The thermostat should be sensing average room temperature, avoid the following:
   HOT SPOTS:
   Concealed pipes or ducts
   Fireplaces
   Registers
   TV sets
   Radios
   Lamps
   Direct sunlight
   Kitchen
   COLD SPOTS:
   Concealed pipes or ducts
   Stairwells-drafts
   Doors-drafts
   Unheated rooms on  other side of wall
   DEAD SPOTS:
   Behind doors
   Corners and alcoves

9. After picking a location that meets the requirements, inspect the wall. Make sure there are no pipes, wiring, or anything else that would interfere with heater or thermostat installation. If required, move them or pick a new location.

Recessed Mount Installation
BEFORE YOU BEGIN: To avoid electrical shock, turn off electrical circuits that pass through the wall where you are going to install the heater.
If you intend to use the optional rear outlet, turn to page 11 for rear outlet installation procedure before you begin to install the heater. Use only the optional grille and boot extension supplied by the manufacturer.
FIND THE STUDS
Use a stud locator 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. Inside edge of the other stud should be about 14½ inches from the one found. Drive finishing nail on inside edge of this stud.

3. Fasten cover to heater with (2) short screws provided.

OPERATING YOUR HEATER

The heater is controlled by means of 24 volt, wall-mounted thermostat. When the thermostat circuit is energized, low voltage relays are actuated which close circuits to the heating element and blower motor. The relay actuates after thermostat calls for “turn on” or “turn off”. Protection against overheating is provided by means of a limit switch located near heating elements, which acts to open relay circuits controlling the heated elements if circulating air volume is decreased. The limit switch automatically restores operation when temperatures reach a normal level. As an additional safeguard, each heating element is equipped with fuse limiters to protect against excessive and prolonged current surges. If these protectors open the heating circuit, the heat limiter must
be replaced by your Service Technician who will determine and correct the cause of failure.
Air volume may be adjusted at the operational rear grilles, if so equipped. Do not attempt to reduce flow of air from main panel (front) grille. To do so would cause shut¬down through the high limit control. For best heating results, do not obstruct air flow by placing furniture in front of outlets. Make sure the free flow of air returning to the blower is not reduced by closing doors between heated spaces.
Caring for Your Heater
ANNUAL UPKEEP NEEDED
Heating Element and Optional Rear Outlet
Keep clean at all times. Clean all foreign materials from rear outlet and top of heating element. Use a soft brush or vacuum cleaner.
For access to heating element, remove (2) screws (Figure 1 on page 6) and grasp face panel near bottom and pull up and out.
After cleaning back of optional rear outlet and heating element, replace face panel.
MOTOR AND FAN
For maximum motor life of fan, the manufacturer recommends the fan be inspected yearly, dust blown out of the ventilating holes and a few drops of

20 non- detergent oil added to bearing cavity (Figure 13).

To get to the motor:

1. Take out four screws holding fan shroud to side flanges of cabinet and remove shroud (Figure 1 on page 6).
2. Before removing the fan blade, remember its position by examining the blade nut and the amount of shaft visible. Scribe or mark the motor shaft in order to reinstall the fan blade to its original place on the shaft.
