HEAT TRAP
The hot water outlet on the 8A0340 model is located on top of the water heater.
An external heat trap is required be installed. The heat trap is to be within one (1)
metre of the hot water outlet, before the first hot water branch and have a vertical
drop of 250 mm from the outlet of the water heater.
PIPE SIZES
To achieve true mains pressure operation, the cold water line to the water heater
should be the same size or bigger than the hot water line from the water heater.
The pipe sizing for hot water supply systems should be carried out by persons
competent to do so, choosing the most suitable pipe size for each individual
application. Reference to the technical specifications of the water heater and
local regulatory authority requirements must be made.
TEMPERATURE PRESSURE RELIEF VALVE
The temperature pressure relief valve is shipped behind the access cover. The
temperature pressure relief valve must be fitted before the water heater is
operated. Before fitting the relief valve, make sure the probe has not been bent.
Seal the thread with an approved thread sealant such as Teflon tape - never
hemp. Make sure the tape does not hang over the end of the thread.
Screw the valve into the correct opening (refer to the installation diagram on
page 33) leaving the valve drain pointing downwards. Do not use a wrench on
the valve body - use the spanner flats provided. A copper drain line must be fitted
to the temperature pressure relief valve (refer to "Relief Valve Drain" on page 37).
The valve must be insulated with
closed cell polymer insulation or
similar (minimum thickness 9 mm)
and the insulation installed so as not
to impede the operation of the valve.
The insulation must be weatherproof
and UV resistant if exposed.
An insulation collar is supplied with
the temperature pressure relief valve
and must be placed over the body of
the valve, prior to fitting the valve to
the water heater (refer to the diagram
on page 36).
