QUARTZ TUBE INSTALLATION
ELECTRIC SHOCK HAZARD
Each heater is equipped with two hi-temperature
silicone lead wires and a ground termination
sure power source conforms to the heater requirements.
Use only Fostoria quartz tubes.
.
Make
• Serious injury or death may occur.
• Disconnect from electrical supply
before installing or servicing this
heater.
• Reector end caps must be installed
prior to powering the unit; refer to
note 3
.
Install heater so that the quartz tubes are horizontal.
Failure to do this may cause the heating element
within the tube to sag and cause premature burnout.
1. Insert quartz tube in the “L”-shaped slots in heater
housing.
2. On each end of the quartz tube, place (1) lead
wire ring terminal, (1) lock washer and (1) hex nut
on the threaded stud and tighten securely (see
image below). Lock washers and hex nuts are
provided in hardware package.
NOTE – Use a second wrench to hold the inner hex nut
in place while tightening the outer hex nut. Failure to
securely tighten this connection will cause the element
to fail prematurely.

SUSPENSION ALTERNATIVES
Your OCH series heater can be mounted with either the
adjustable mounting brackets or by chain suspension.
Both mounting options are included with the heater in
the hardware package.
Standard Mounting:
In the hardware bag shipped with your heater you
will nd two adjustable mounting brackets and
fastening hardware.
Using the mounting centers
specied in gures 1 & 2, mount your adjustable
mounting brackets (bends to the inside). Once
mounted, assemble the heater to brackets (gure 3)
with mounting hardware, these brackets enable the
heater to be angled in 15-degree increments up to
45 degrees.
Chain Suspension:
The heater can also be chain-hung as shown in
gure 4.
Cut the 16ga. chains (two 4 foot chains are
provided) to desired length. Attach chains to heater
with “S”-hooks provided and suspend from overhead
structure. Crimp “S”-hooks closed after assembly.
