GAS INLET
The gas connection is made through the grommet in the left hand side panel 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 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 27) 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 Vulcan 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 Vulcan warranty. Damaged valves must be
replaced.
