3.0 Mounting and Electrical Installation
3.1 Mounting
Mount the heater according to the following installation instructions:
1.
Mount the heater at or above the MINIMUM MOUNTING HEIGHT (See Table on page 5)
2.
Ensure the MINIMUM DISTANCE TO COMBUSTIBLES is maintained above, below and around the
heater. (See Table on page 5)
3. There are several methods for mounting your HZE
HeatProjector.
Each HZE
HeatProjector
comes
with a
3/4”
EMT compression fitting and enough high temperature lead wire for mounting at the
minimum distance to combustibles.
Options:
a.
Use
3/4”
EMT conduit
(1) Radiant Optics recommends using the
3/4”
EMT compression fitting provided to mount
your heater using
3/4”
EMT conduit.
(2) Enough high temperature lead wire is provided to mount the heater at the minimum dis-
tance to combustibles:
6”
for the HZEHP
e
7500 model and
9”
for the HZEHP
e
15000 model.
Additional lengths of lead wire and ground wire can be attached to the wires provided using
a butt splice or connection inside a conduit body. Splices must be done per the NEC and local
codes.
(3) Comfort is best obtained with the heater off to one side and angled at 30º. Straight EMT
from heater to wall or ceiling will give a 45º mounting angle. Bend EMT as necessary to attain
desired mounting angle.
b.
Use chains and flexible conduit
(1) the heater can also be hung by 4 corners using chain. Connect chain to the heater lip by
drilling 4 holes for hooks or attach chains mechanically. Position the heater to obtain a
mounting angle between 20º and 45º.
(2) Use metal flexible conduit to electrically connect leads per NEC and local codes.
c.
Optional Mounting kits from Radiant Optics—Radiant Optics offers several different mount-
ing kits for both wall and ceiling mounting as well as in
-
ceiling mounting options (continued
