Storage tank outlet connections
It is recommended that a heat trap be installed on the outlet
piping of the storage tank in order to prevent convective
heat losses and to maintain the efciency of the hot water
system. If your system is gas boosted, the gas continuous
flow water heater supplied with the hot water system is to be
installed and connected to the hot water line after it leaves
the storage tank. Refer to the installation manual supplied
with the gas continuous ow water heater for specications,
dimensions, suitable installation locations and details on how
to install it.
Any pipes delivering hot water to the premises are to be
installed with sufcient piping insulation to maintain the
efciency of the hot water system and to prevent heat loss.
Any piping insulation that may be exposed to sunlight must
also be UV resistant. The tempering valve provided in the
KKSSUGA kit is to be installed in order to temper any water
owing to xtures primarily used for the purposes of personal
hygiene (e.g. bathroom or ensuite xtures). The water
supplying these xtures shall not exceed 50°C as required by
AS 3500.4.

Relief valve piping
A temperature and pressure relief valve comes supplied with
the storage tank and must be installed on the relief valve
connection near the top of the tank.

RELIEF
VALVE
The drainage piping from the relief valve (and the one on
the inlet if installed) must have a constant downward fall
and must be plumbed to an outside drain. The outlet of
the drainage piping must be left open to the atmosphere at
all times, and installed in a frost free environment.

warning
Failure to operate the relief valve easing gear at least
once every six months may result in the storage tank failing
or in extreme cases, exploding. Continuous leakage of
water from the valve may indicate a problem with the
hot water system.
