New Buck Corporation manual Gas Pressure Check, MODEL CR8T

GAS PRESSURE CHECK

Check the inlet pressure to the burner to ensure that it is as shown in the table below. NOTE: The pressure check point is located on right side of valve facing the burner.

The appliance and its main gas valve must be disconnected from the gas supply piping sys- tem during any pressure testing of that system at test pressures in excess of 1/2 psi (3.5kPa).

The appliance must be isolated from the gas supply piping system by closing its equipment shut-off valve during any pressure testing of the gas supply piping system at test pressures equal to or less than 1/2 psi (3.5 kPa).

MODEL CR8T
Gas	Natural	Propane (LP)
Maximum Heat Input	27,000	27,000
Minimum Heat Input	11,000	11,000
Gas Inlet Pressure:
Maximum	10.5 ins. W.C.	13.0 ins. W.C.
Minimum	5 ins. W.C.	11 ins. W.C
Manifold Pressure	3.5 ins. W.C.	10 ins. W.C.

NOTE: On initial installation it may be required to bleed out air in the gas lines. Do this by holding the knob and turning the knob to the pilot position for about 30 seconds.

The pressure should be checked with the heater burning and the control set on high. After measuring the pressure, close pressure tap screw, ensuring there are no leaks. Regulator pressure check screw located above “OFF/ PILOT/ ON” knob at right upper corner of valve.
