Manifold (Outgoing) & Inlet (Incoming) Pressure Check Procedures - kozy heat CHASKA-XL CSK-335 Installation & Operating Manual

MODEL #CSK-335 ONLY: PRESSURE TEST - MANIFOLD & INLET PRESSURE
IMPORTANT NOTICE: A pressure check tap for both the manifold (outgoing) and inlet (incoming) pressure has been
incorporated into the valve by HONEYWELL Controls. The left pressure tap is the manifold pressure and the right
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. Push the control knob [A] on the gas valve in slightly and turn to the 'ON' position.
5. Turn the burner 'ON' by depressing the rocker switch [C] and note manometer reading.
6. Depress 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 depressed to the 'ON' position.
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. Push the control knob on the gas valve [A] in slightly and turn to the 'ON' position. (Burner should not come
'ON') and note manometer reading.
5. Turn the rocker switch [C] to the 'ON' position by depressing the switch and check the pressure to ensure that
it stays near the maximum inlet pressure.
6. Depress the rocker switch [C] to the 'OFF' position.
7. Turn the pilot 'OFF' by pushing the control knob in slightly and turning to the 'OFF' position.
8. Disconnect hose and tighten screw (clockwise). Screw should be snug, do not over tighten.
9. Relight pilot. Push the control knob [A] in slightly and turn 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.
