Installation & Operation Manual
4.3.2
Gas Offset Pressure Adjustment
If the offset pressure is incorrect an adjustment can be
made to bring the offset pressure within the required
range. Prior to making any gas valve adjustments:
• Ensure that the inlet gas pressure from
Section
4.2
is
within the specifi ed range.
• Ensure that the manometer has been connected in
accordance to steps a-f in
Section 4.3.1
.
•
Ensure that all hoses, barbed fittings plugs and caps
are securely in place and not leaking.
• With the heater running read and record the offset
pressure displayed on the manometer. If an
adjustment is still required:
•
Remove the offset adjustment sealing cap (using a
T40 torx driver) to expose the torx adjustment screw
below.
•
Using a T40 Torx driver turn the plastic adjustment
screw as follows:
To Increase Offset Pressure:
Turn the adjustment screw 1/4 turn clockwise.
To Decrease Offset Pressure:
Turn the adjustment screw 1/4 turn counter clockwise.
• Once the proper gas offset pressure has been
achieved. Securely reinstall the cap.
• Shut down the heater at the user interface.
•
Remove manometer.
• Before operation, test the complete gas supply system
and all connections for leaks using a soap solution.
Do not use an open flame to test for leaks.
WARNING
Failure to secure or replace the pressure tap plugs will allow gas to
leak from the valve into the heater body which could result in prop-
erty damage, severe injury, or death.
CAUTION
Some leak test solutions (including soap and water) may cause
corrosion or stress cracking. Rinse the piping with water after testing.

Special Precautions for LP Gas
This appliance is approved for use with LP (Propane) and
Natural Gas in Australia only. It is approved for use with
Natural gas only in New Zealand. Under the same
environmental conditions, liquid propane (LP) gas is
more dense or heavier than air and will more readily
collect or pool in enclosed areas if adequate ventilation is
not provided. It is not recommended to install LP gas
heaters in enclosed areas such as pits. Locate heaters a
safe distance from LP gas cylinders and filling
equipment. Consult the Australian / New Zealand
Standard AS/NZS 1596 and gas installation standard
AS/NZS 5601, and any other local codes and fire
protection authorities about specific installation
restrictions in your area.
For ALL installations the combustion air openings
requirements and AS/NZS 5601 MUST be followed
for safe and proper operation.
