Installation Instructions
1. Hanging Frame Mounting:
Before attaching
the heater to the U” shaped hanging frame,
mount the frame in position to the overhead
building structure. Use 1/2 inch diameter or
larger bolts on each side leg. Position the
frame to facilitate the connection of gas supply
piping, and on models equipped with an
electrical valve, the electrical supply wiring.
2. Gas Supply Piping:
The piping provided with
the heater is assembled to nestle in the
channel of the hanging frame. Connect an
additional length of 1/2 inch pipe long enough
to clear the top of the frame.
Screw the heater onto the 1/2” NPT x 1 inch
long nipple at the outlet end of the piping. The
heater should be turned to allow the control
handle to face in the desired direction.
Note: A 1/8
inch NPT plugged tapping,
accessible for test gauge connection, must be
installed immediately upstream of the gas
supply connection to the heater. Use a suitable
pipe thread sealant on all gas connections.
3. Heater Mounting:
Set
the heater (less ref
lector) with the piping assembly attached into
the suspended hanging frame. The piping will
nestle in the hanging bracket channel. Install
and tighten the two (2) 3/8
inch bolts supplied
with the frame and firmly secure the base of the
heater in place.
Electrical Supply:
On the A244V 24 volt
model, the electrical inlet is provided on the
right side of the heater opposite the gas inlet
piping. The electrician should supply a
connection box as shown adjacent to the
heater electrical inlet and run ½” rigid
waterproof conduit up to the right just inside the
frame channel.
WA R N I N G :
T h e m i n i m u m f i r e h a z a r d
clearance marked on the heater must be
maintained from vehicles parked below the
heater.
The electrical input required to the heater is
0.550 Amps at 24V (rated at 8 Watts). A 4OVA
transformer will service up to three (3) heaters.
A NEC Class 2, 24 volt transformer (20 VA
rating) circuit must be supplied to the heater.
The transformer is to be installed in the junction
box or in accordance with local codes, but in no
case closer than three (3) feet to the reflector.
4. Piping Hook-up:
Connect the additional gas
supply piping. Leak test all piping joints with a
soap-water solution. Do
NOT
use a match to
test for gas leaks.
5. Reflector Mounting:
Attach the reflector by
means of the three (3) stainless steel wingnuts
at the top of the heater.
6. Heater
Start-up:
Follow the lighting and
operating instructions on the rating plate
attached to the hanging frame.
