CONNECTIONS – PLUMBING

GAS INLET
The gas connection is made to the left hand side of the gas control, through the grommet in the left hand
side panel on outdoor models. The pipe work must be cleared of foreign matter before connection and
purged before attempting to light the water heater. An isolation valve and disconnection union must be
installed to allow servicing and removal of the water heater.
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 gas input of this
water heater (
refer to table on page 22) 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 isolating cock 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.
Caution: Care is necessary when tightening fittings into the gas valve. The gas valve casting may crack if
the fittings are over tightened. Cracked valve castings are not covered under the Rheem warranty. Damaged
valves must be replaced.
