A.F.U.E.
Gas line connection can be made near the lower rear of the appliance (3/8" gas hookup). You must
supply a shutoff valve installed in a visible location within 3' of the insert.
IN SOME AREAS, GAS LINE PRESSURE MAY BE MORE THAN 1/2 PSIG (14" WC). IF YOU
BELIEVE THAT THIS MIGHT BE THE CASE IN YOUR LOCALITY, CONTACT YOUR GAS
SUPPLIER OR LOCAL UTILITY COMPANY. LINE PRESSURE GREATER THAN 1/2 PSIG
WILL DAMAGE THE APPLIANCE VALVE. YOU MUST INSTALL A REGULATOR UPSTREAM
FROM THE APPLIANCE IF LINE PRESSURE IS GREATER THAN 1/2 PSIG.
During any pressure testing of the gas supply piping system that exceeds test pressures of 1/2 PSIG, this
appliance and its individual shutoff valve must be disconnected from the piping system. If test pressure is
less than or equal to 1/2 PSIG, then this appliance must be isolated from the piping system by closing its
individual shutoff valve. The gas valve is supplied with pressure test ports for checking input and output
pressures. These are located just below the on/off knob and can be found inside the hinged lower access
grill. The port on the left is for output pressure and the port on the right for input. Pressure can be
checked by turning the captured screw counterclockwise two or three turns and then placing the
manometer tubing over the test port. BE SURE TO CLOSE CAPTURED SCREWS AFTER TESTING
BY TURNING THEM CLOCKWISE. DO NOT OVERTIGHTEN SCREWS.
NOTE: To make flame and heat output adjustments, turn the HI-LO knob located on the center of the
valve (as seen below). Turn clockwise for a higher flame and counterclockwise for a lower flame
The Quadra-Fire GB40-I is listed to ANSI Z21.11.1 and CAN1-2.1 by OMNI-Test Laboratories, Inc.
