INSTALLATION

TANK WATER SUPPLY
If the water heater is supplied with water from a tank supply and a pressure
pump system is not installed, then the bottom of the supply tank must be at
least 1 m above the highest point of the hot water plumbing system, including
the water heater. Care must be taken to avoid air locks. The cold water line to
the water heater should be adequately sized and fitted with a full flow gate
valve or ball valve.
WALL BRACKETS
It is a requirement of AS 5601 and AS/NZS 5601.1 to secure the water heater
to the wall. The top of the unit is to be secured to the wall (or screen) with the
wall brackets provided using fasteners suitable for the wall type and
application.
The fasteners must be capable of bearing the weight of the water heater so it
may neither work loose, pull away from the wall nor impose any load on the gas
and water pipe work connected to the water heater. Refer to the fastener
manufacturer‟s information and recommendations for the type of fastener to
use for the wall type and load bearing requirements.
To fit the wall brackets:
Position a bracket against the wall
on one side and toward the top of
the water heater and mark the
fixing points on the wall where the
bracket is to be secured.
Repeat this process with the
remaining bracket on the other side
of the water heater.
Drill
holes in the wall to receive
suitable
fasteners
for the wall
brackets
.
Fix the wall brackets to the wall
using suitable fasteners.
Secure the bracket to the side of
the water heater using the self
tapping screws provided.
