The gas pressures of the appliance are factory set and will normally not require adjustment. When
checking the operating pressures the combustion chamber glass must be on.
If installing an LPG unit with a vertical flue termination, the appliance must be uprated to
33 MJ/h using the uprating kit and instructions supplied with the unit.
IMPORTANT
To check and set the burner pressures
1. Turn on the gas and power supply to the unit.
2. Refer to the data plate for applicable test point pressures.
3. The test point is on the gas control valve. Using a suitable screw driver loosen the captivated
test point screw and attach a manometer.
4. Using the manual control switch (on the appliance), turn the unit on and switch to the HIGH
setting, and adjust the pressure as necessary.
5. Disconnect the solenoid (yellow wire), this will ensure the unit is on the lowest setting, and set
the appliance to the LOW setting. Adjust the pressure as necessary. Reconnect the solenoid.
6. After checking the pressures, turn the unit off, remove the manometer, and replace the test
point screw.
7. Turn the heater on and off a few times to check ignition.
8. When you are satisfied that the heater is working correctly reassemble and start the appliance
to check the flame pattern.
