CONNECTIONS – PLUMBING
21
GAS INLET
The gas connection is made at the underside of the water heater. The pipe work must be cleared of foreign
matter before connection and purged before attempting to operate the water heater. An isolation valve and
disconnection union must be installed to allow servicing and removal of the water heater (refer to the diagram
on page 20).
Note: Refer to the Gas Installations Standard AS 5601 or AS/NZS 5601.1 for the correct method of sizing the
gas supply pipe to the water heater. The pipe size selection must take into account the high gas input of this
water heater (refer to table on page 18) as well as all of the other gas appliances in the premises.
Warning: Always isolate the water heater before pressure testing the gas supply system. Disconnect the
water heater after the isolation valve to prevent the risk of serious damage to the gas control. The Rheem
warranty does not cover damage of any nature resulting from failure to observe this precaution. Refer to rating
label for gas types and pressures.
