The Safety Alert Symbol is used to indicate a
risk of personal injury
Familiarize yourself with these instructions before attempting
to install or operate this Radiant Heater.
The system designer is responsible for the safety
of this equipment and should install adequate
back-up controls and safety devices with their
electric heating equipment. Where the consequences of failure could result in personal injury or
property damage, back-up controls are essential.
Before Installing
1. Open carton and remove heater at the place of installation.
Mounting clamps are in parts bag in carton.
2. Check nameplate volt and watt rating against your power sup-
ply voltage and heating requirements of your installation. This
nameplate is located on one end of the heater.

INSTALLATION
ELECTRIC SHOCK HAZARD. Disconnect all power
before installing or servicing heater. Failure to do
so could result in personal injury or property damage. Heater must be installed or serviced by a qualified person in accordance with the National
Electrical Code, NFPA 70.
1. These radiant heaters are designed for indoor installation only.
2. Clamps — Heaters are mounted by means of the mounting
clamp and 3/8” bolt assembly which is used as shown in Figure
2. Clamp assembly may be attached to heater by sliding over
end or by snapping over top of extruded frame section at any
point along its length. (See Figure 3.) For proper heater support,
the maximum distance between clamps must not exceed 48”.
On extra-long heaters, more than two clamps are furnished.
3. Mounting Holes — When heaters are mounted adjacent to
each other in the same plane, note that distance between
mounting holes on framing to support heaters will be 311/16”minimum. When heaters are not in the same plane, i.e.
set at an angle to one another, distance between mounting holes
in framing will be either greater or less than 3-11/16”.
4. Framing — Where an extensive installation is being made, the
use of continuous slot metal framing manufactured by others
will be of assistance in saving time and money. The framing is
reusable.
5. R
eflector Spacer Sheets — Where heaters are not mounted side
by side (see Figure 4), reflector spacer sheets can be used between
heaters. These reflector spacer sheets and companion reflectors
consisting of an extruded aluminum housing with reflector sheets
and mounting clamps are available. Check factory.
6. Insulation — Where unusually high work temperatures are
encountered, it may be desirable to insulate backs of heaters
with high-temperature fibrous insulation. A suggested method
of accomplishing this is indicated in Figure 4.
7. Ventilation — Where solvents, water, etc. are being evaporat-
ed from work in process, it is necessary to provide substantial
quantities of ventilation air to carry away the resulting vapors.
FIRE HAZARD. Since Radiant heaters are capable
of developing high temperatures, extreme care
should be taken to:
A. Keep combustible materials at least 6” away
form sides and back of heater housing and its supporting brackets and spaced far enough in front of
heater (heating element side) so thermal radiation
from the elements will not ignite combustible
materials.
B. If combustible materials are being processed,
stoppage of process should initiate immediate
heater shutdown and interception of residual heat
from radiant heaters (use radiation baffles or move
heaters away from work).
C. In the case of solvents of an explosive nature,
ventilation air must be in sufficient volume to
dilute the solvent vapor so that explosive mixtures
cannot occur, refer to NFPA 86, Standard for Ovens
and Furnaces.
