Manifold & Incoming Pressure Check Procedures - kozy heat 56101 'Windom" Installation And Operating Manual

IMPORTANT NOTICE: A pressure check tap for both the manifold (outgoing) and inlet (incoming) pressure has
been incorporated into the gas valve. The top pressure tap is the manifold pressure and the bottom pressure tap
measures the incoming pressure. Follow the instructions below for proper pressure testing procedures.
TO CHECK THE MANIFOLD PRESSURE:
1. Light pilot.
2. Loosen the manifold pressure tap [D] by turning the screw counter-clockwise.
3. Attach manometer to pressure tap using a 5/16" I.D. hose [F].
4. Turn black control knob [A] to the 'on' position.
5. Turn the burner on by depressing the rocker switch [C] to expose the 'red' and note manometer reading.
6. Turn the rocker switch [C] to the 'off' position.
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 that it is completely sealed.
Manometer should read no pressure when the rocker switch is turned on.
NOTE: If manifold pressure reading is within the normal range, an incoming pressure check is not necessary. A
too high or too low pressure reading warrants an inlet (incoming) gas pressure check.
TO CHECK THE INLET PRESSURE:
1. Loosen Inlet pressure tap screw [E] by turning screw counter-clockwise.
2. Attach manometer using a 5/16" I.D. hose [F].
3. Light the pilot.
4. Turn the black control knob [A] to the 'on' position (burner should not come on) and note manometer reading.
5. Turn the rocker switch [C] to the 'on' position and check the pressure to ensure that it stays near the
maximum inlet pressure.
6. Turn the rocker switch [C] to the 'off' position.
7. Turn the pilot to the 'off' position.
8. Disconnect hose and tighten screw (clockwise). Screw should be snug, do not over tighten.
9. Relight pilot and turn the control knob [A] to the 'on' position. Attach manometer to the inlet pressure tap to
verify that 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.
CAUTION: A LOW PRESSURE READING
CAN CAUSE DELAYED IGNITION.
