Warning
It is forbidden to connect and stop valve or non return valve between the inlet security
group and the water heater.
Caution
During heating of the water heater (due to temperature increase) water will dribble from
the inlet security group. This is a normal phenomenon. This should never be prevented
of blocked. The outlet of the inlet security group should remain open at all times to its
surroundings.
Hot water side
See (B) in the installation diagram
1. Mount the top flange (2" connection) incl. the sealant ring by means of bolt/nut-

2. Optional: fit a temperature gauge (12) so you can check the temperature of the tap
water.
3. Connect the overflow side of the T&P (3) via an open connection to the waste water
discharge.
4. Fit a stop valve (11) in the hot water outlet pipe for servicing.
5. When a circulation pipe is needed, continue with the mounting of the circulation pipe
(3.6.3 "Circulation pipe").

If an immediate flow of hot water is required at draw-off points, a circulation pump can be
installed. This improves comfort, and reduces water wastage.
1. Fit a circulation pump (6) of the correct capacity for the length and resistance of the
circulation system.
2. Fit a non-return valve (5) after the circulation pump to guarantee the direction of
circulation.
3. Fit two stop valves for servicing (4).
