Radiant Heaters
Specifications The Safety Alert Symbol is used to indicate a risk of per-
sonal injury.
Please familiarize yourself with these instructions before
attempting to install or operate this Radiant Heater.
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.
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 conse-
quences of failure could result in personal injury or
property damage, back-up controls are essential.
INSTALLATION
ELECTRIC SHOCK HAZARD. Disconnect all power
before installing or servicing heater. Failure to do
so could result in personal injury or property dam-
age. 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. Mounting Clamps — Mount heaters by using the mounting
clamp and 3/8” bolt assembly.
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 Fig. 2) 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 3-11/16”
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 several
concerns will be of assistance in saving time and money. The
framing is reusable.
