CONNECTIONS – PLUMBING
GAS INLET
The gas connection is made through the left hand side near the access cover to
the gas control. 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/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 34) 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.
