INSTALLATION INSTRUCTIONS
GETTING STARTED: FIRST CHOOSE A MOUNTING INSTALLATION OPTION.
WARNING:
This unit is intended for use ONLY as a ceiling mounted
heater. Mounting on a wall or sloping surface such as a
roof is a risk of fire due to possible overheating of the unit
or igniting nearby combustible materials.
KEY SLOT OPTION:
1. Locate a desired position on your ceiling in the area to
be warmed. (Heater should be at least 3 feet (0.9m)
away from the nearest wall or other combustible
material)
2. The mounting bracket may be attached to a single
joist (Fig. A) or span across two joists (Fig. B) Failure
to mount heater to joists can result in injury and or fire
hazards.
3. If you are installing the bracket to an unfinished ceiling
with exposed joists, proceed to step 4. On a finished
ceiling the joists are hidden behind the ceiling dry wall
or plaster. You must locate and mark the location of
the center of the joists in the mounting area. Joists are
typically 1-1/2 inch (38mm) wide and 16 inch (406mm)
or 18 inch (457mm) apart. They usually run parallel
with the narrow dimension of the room. A “Stud Finder”
available at most hardware stores may help in locating
the center of these hidden joists.
4. Using the mounting bracket as a template, line up one of
the key slots at each end of the bracket with one or two
joists and mark the slotted openings. If you cannot line
up the holes in the bracket with the joists you will have to
use other mounting methods. See “Installing a Mounting
Board.”
5. Using a 1/8-inch (3.2mm) drill bit, drill a hole in the
center of each marked key slot. Install the two screws
provided leaving about 1/4 inch (6.4mm) between the
head of the screw and the mounting surface. Slip the
mounting bracket over the screw heads and slide the
bracket to engage the screws in the slots. Tighten
screws securely.
INSTALLING A MOUNTING BOARD
(If required)
:
If your joists are more than 18 inch (457mm) apart, or
you have chosen to mount the heater at an angle to the
joists as in a corner or to a suspended ceiling, a mounting
board will be needed to provide a surface to attach the
mounting bracket (Fig. C). The mounting board should be
a board measuring approximately 1 inch (25.4mm) thick
by 2 inch (50.8mm) and 18 inch (457mm) in length or long
enough to span two or more joists (For Suspended Ceiling
installations make the length 23.75 inch (603.25mm)
exactly). For swivel or key slot installations, securely
bolt or screw the mounting board into desired position.
Continue with the installation following the instructions for
the desired heater bracket mounting installation.
