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.
Remove the yellow warning label from the gas control after connecting the gas
supply pipe.
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 31) 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 type and pressure.
Caution: Care is necessary when tightening fittings into the gas control. The
gas control casting may crack if the fittings are over tightened. Cracked gas
control castings are not covered under the Rheem warranty. A damaged gas
control must be replaced.
