Pressure Testing - kozy heat MPS-30 Minneapolis Installation And Operation Manual

IMPORTANT NOTICE: Pressure check taps for manifold (outgoing) and inlet (incoming) pressure have been incorporated into
NOTE: The appliance and its individual shutoff valve must be disconnected from the gas supply piping system during any
pressure testing of that system at pressures in excess of ½ psi.
NOTE: The appliance must be isolated from the gas supply piping system by closing its individual manual shut-off valve during
any pressure testing of the gas line at test pressures equal to or less than ½ psi (3.5 kPa).
INLET PRESSURE TEST:
1. Loosen inlet (IN) pressure tap screw (counter-clockwise).
2. Attach manometer using a 1/4" I.D. hose.
3. Light fireplace using hand held remote control. Note manometer reading.
4. Turn fireplace off using hand held remote control.
5. Disconnect hose and tighten screw (clockwise). Screw should be snug, do not over tighten.
6. Relight fireplace using hand held remote control. Reattach manometer to inlet pressure tap to verify it is completely sealed.
Manometer should read no pressure.
NOTE: If inlet pressure reading is too high or too low, contact the gas company. Only a qualified gas service technician should adjust
incoming gas pressure.
CAUTION: A LOW PRESSURE READING CAN CAUSE DELAYED IGNITION
