Gas Connection; Sizing And Connecting - Takagi GS-2000W-AU Installation Manual

Check the gas type label to make sure that the water heater is available for your gas, and that the gas inlet
pressure is within the appropriate range. (Please refer to p. 3.)
1. Gas pressure below this specified range for the water heater and/or insufficient gas volume will ad-
versely affect performance.
2. Inlet gas pressure must not exceed the above maximum values; gas pressure above the specified range
will cause dangerous operating conditions and damage to the unit.
3. Until testing of the main gas line supply pressure is completed, ensure the gas line to the water heater
is disconnected to avoid any damage to the water heater.
Conversion of this unit from natural gas to propane or propane to natural gas cannot be done in
the field. Contact your local retailer or distributor to get the correct unit for your gas type.
• Size the gas piping for the water heater according to AS5601 installation code.
• Always use approved connectors to connect the unit to the gas line. Always purge the gas line
of any debris before connecting to the water heater.
• Install a manual gas shut-off valve between the water heater and the gas supply line.
• The regulator is preset at the factory. It is computer controlled and is not to be adjusted by any
person other than a qualified Service Provider.
• When the gas connections are completed, it is necessary to perform a gas leak test either
by applying soapy water to all gas fittings and observing for bubbles or by using a gas
leak detection device.
