Inlet and outlet pressure taps are provided on the front face
of the gas control for a test gauge connection to measure
the manifold pressure. Use a small flat blade screwdriver to
crack open the screw in the center of the tap. Position a
rubber hose over the tap to obtain the pressure reading.
THE APPLIANCE AND ITS INDIVIDUAL SHUT-OFF
VALVE MUST BE DISCONNECTED FROM THE GAS
SUPPLY PIPING SYSTEM AND ISOLATED DURING ANY
PRESSURE TESTING OF THE SYSTEM AT TEST
PRESSURES EQUAL TO OR IN EXCESS OF ONE-HALF
(1/2) PSIG (3.5 KPA).
Step 6. Wiring the Appliance
NOTE: Electrical wiring must be installed by a li-
censed electrician.
CAUTION: DISCONNECT REMOTE CONTROLS IF AB-
SENT FOR EXTENDED TIME PERIODS. THIS WILL PRE-
VENT ACCIDENTAL APPLIANCE OPERATION.

•
This appliance
DOES NOT
require 110-120 VAC to operate,
unless using an optional remote or blower.
WARNING: DO NOT CONNECT 110-120 VAC TO
THE GAS CONTROL VALVE OR THE WALL
SWITCH OR THE APPLIANCE WILL MALFUNC-
TION AND THE VALVE WILL BE DESTROYED
.
Wall Switch
Position the wall switch in the desired position on the wall.
An assembly of 18 ft of 20 AWG is provided with the appli-
ance to connect the wall switch to the appliance. Instead of
the supplied assembly, wire with a length of 25 ft or less and
a gauge of 20 AWG through 14 AWG is acceptable. The
wire needs a jacket with a temperature rating of 140
o
F (60
o

or higher. At the appliance connect the wire to the ON/OFF
switch pigtails.
CAUTION: LABEL ALL WIRES PRIOR TO DISCONNEC-
TION WHEN SERVICING CONTROLS. WIRING ERRORS
CAN CAUSE IMPROPER AND DANGEROUS OPERATION.
VERIFY PROPER OPERATION AFTER SERVICING.
