3. INSTALLATION
A. PLACEMENT
Room units can normally be placed on standard flooring systems with any type of covering, i.e., wood, carpet,
linoleum; but, heater weight must be considered. If in doubt, consult a building contractor or an architect. (See Table
3 for weight and physical dimensions of unit being installed.)
Room units are equipped with adjustable leveling legs or a security base. When installing a room unit with
adjustable leveling legs on carpet, adjust the legs so that carpet compression does not cause upward bowing of unit's
floor panel. Leg extension should not, however, exceed 3/4 inch overall. On extremely thick padded carpet, it may be
necessary to place the unit on a one inch nominal board, 8 3/4 inches wide and of appropriate length for the heating
unit being installed. Failure to follow these guidelines could result in damage to the flooring.
B. CLEARANCE REQUIREMENTS
Allow 1 5/8 inches clearance from the sides and back of the heater, and a minimum of four inches from the top
of the heater. The factory supplied wall mounting bracket, located on the heater's shipping pallet, will provide the
correct wall to back of heater clearance. If the heater is a 120V plug-in model with a security base, the base will
provide the proper wall to back of the heater clearance. If enclosing the S Series unit in a wooden cabinet or recessing
unit into a wall, allow two inches clearance on sides and four inches on top. Do not enclose or otherwise obstruct
access to the heaters's front panel and grill. It is not recommended to recess or enclose an EXT Series unit as it may
cause some inaccuracy in room thermostat operation. All objects must be kept a minimum of four inches from all unit
surfaces and 15 inches from the grill.
(NOTE: For ease of servicing the EXT series unit, a clearance of 12" on the right side
of unit is recommended.)
C. SET-UP PROCEDURE
GENERAL NOTE:
A. For cross reference to number coded components,
see Figure 7 (S series) or Figure 8 (EXT series).
•Room Unit and Site Preparation
1. Remove control knob (44), if unit is equipped, grill (46) and grill
support bracket (22) from unit.
(NOTE: If unit being installed is equipped with a security
base, skip to Step 4.)
2. Establish unit location and attach wall support bracket (1) to
wall using the lag bolts provided. (See Figure 3). The wall
support bracket is shipped on the pallet under the room unit. A
plastic bag containing the wall support bracket hardware kit (58)
is provided inside the lower fan cavity. The top of the bracket
should be 26" from the floor.
(NOTE: The lag bolts must attach to wood wall studs. If the
wall is not a standard wood studded structure,
alternate fasteners must be used to securely attach
the wall bracket.)
