Gas Connection
• Fit a union to the water heater gas
inlet for easy connection and removal.
The thread diameter is R¾/20.
• Fit an AGA approved isolating gas
cock in the supply line adjacent to
the water heater gas connection.
• Ensure that the supply pipe and
the gas pressure regulator (LPG
or Natural Gas) has sufcient ow
capacity for this and other appliances
connected to the tting line. Refer to
AG 601 for size of pipe.
• For LPG appliances, ensure that
gas cylinders are of sufcient size.
The water heater alone will require a
regulator of 4kg per hour capacity.
• Before connecting the appliance to
the gas service, purge any debris or
air from the gas service. Venting of
purged gas shall be an area free of
sources of ignition.
Close the isolating gas cock prior to
connection of the appliance.
• After connection, check all joints for
leaks with an approved leak tester.
Refer to AG 601 Installations
Standard for pipe sizing details. For
