INSTALLATION
25
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 BRACKET
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 bracket 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 bracket:
Position the bracket against the wall,
ensuring the bracket is centered at
the rear of the water heater top, and
mark the fixing points on the wall
where the bracket is to be secured.
Drill
holes in the wall to receive
suitable
fasteners
for the wall
bracket
.
Fix the wall bracket to the wall using
suitable fasteners.
Secure the bracket to the top of the
water heater using the self tapping
screws provided.
HOT WATER DELIVERY
This water heater can deliver water at temperatures which can cause scalding.
It is necessary and we recommend that a temperature limiting device be fitted
between the water heater and the hot water outlets in any ablution and public
areas such as a bathroom, ensuite or public amenities, to reduce the risk of
scalding. The installing plumber may have a legal obligation to ensure the
installation of this water heater meets the delivery water temperature
requirements of AS/NZS 3500.4 so that scalding water temperatures are not
delivered to a bathroom, ensuite or other ablution or public area.
