Pressure Testing - kozy heat Windim-WDM 56101 Installation And Operation Manual

IMPORTANT NOTICE: Pressure check taps for manifold (outgoing) and inlet (incoming) pressure have been incorporated into the
NOTE: The appliance and its individual shutoff valve must be disconnected from 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 5/16" I.D. hose.
3. Light pilot.
4. Turn gas control knob to „ON‟ (burner should not light). Note manometer reading.
5. Press rocker switch to „ON‟. Check pressure to ensure it stays near maximum inlet pressure.
6. Press rocker switch to „OFF‟.
7. Turn gas control knob to „OFF‟.
8. Disconnect hose and tighten screw (clockwise). Screw should be snug, do not over tighten.
9. Relight pilot and turn gas control knob to „ON‟. 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
the incoming gas pressure.
MANIFOLD PRESSURE TEST:
1. Light pilot.
2. Loosen manifold („OUT‟) pressure tap screw (counter-clockwise).
3. Attach manometer to pressure tap using a 5/16" I.D. hose.
4. Turn gas control knob to „ON‟.
5. Press rocker switch to „ON‟ and note manometer reading.
6. Press rocker switch to „OFF‟.
7. Disconnect manometer hose and tighten screw (clockwise). Screw should be snug, do not over tighten.
8. Attach manometer to manifold pressure tap to verify it is completely sealed. Manometer should read no pressure when rocker switch is
pressed to „ON‟.
