Heat & Glo LifeStyle CFX-IN-B, FB-Grand, FB-IN Gas Pressure Requirements, Wiring the Fireplace

Step 5. Gas Pressure Requirements

Pressure requirements for these gas appliances are shown in the table below.

Pressure	Natural Gas	Propane
Minimum	5.0 inches	11.0 inches
Inlet Pressure	w.c.	w.c.
Maximum Inlet	14.0 inches	14.0 inches
Gas Pressure	w.c.	w.c.
Manifold	3.5 inches	10.0 inches
Pressure	w.c.	w.c.

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 FIREPLACE 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 Fireplace

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.

For Standing Pilot Ignition Wiring

Appliance Requirements

•This appliance DOES NOT require 110-120 VAC to operate.

•Models FB-Grand and FB-IN require 110-120 VAC if op- tional blower is added to the system.

!WARNING: DO NOT CONNECT 110-120 VAC TO THE GAS CONTROL VALVE OR THE APPLI- ANCE WILL MALFUNCTION AND THE VALVE WILL BE DESTROYED.

Wall Switch

Position the wall switch in the desired position on a wall. Run a maximum of 25 feet (7.8 m) or less length of 18 A.W.G. minimum wire and connect it to the fireplace valve pigtails.

!WARNING: DO NOT CONNECT 110-120 VAC TO THE WALL SWITCH OR THE CONTROL VALVE WILL BE DESTROYED.

CAUTION: LABEL ALL WIRES PRIOR TO DISCONNEC- TION WHEN SERVICING CONTROLS. WIRING ERRORS CAN CAUSE IMPROPER AND DANGEROUS OPERATION. VERIFY PROPER OPERATION AFTER SERVICING.
