Pressure Testing - Quadra-Fire DV-40 Installation, Operation, Venting And Maintenance Instructions

This appliance must be disconnected from the gas supply piping system if any testing is done to the
system that exceeds the test pressure of 1/2 PSIG. If the 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
above the on/off knob and can be found at the rear of the appliance. Pressure can be checked by turning
the captured screw counterclockwise two or three turns and then placing the manometer tubing over the
test port. The inlet pressure should be checked with the burner lit. 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 counterclockwise for a higher flame and clockwise for a lower flame.
Inlet and Manifold Pressures can only be taken with the burner lit.
