Hot Water side
See (B) in the installation diagram (2.1 "Installation diagram").
Note
Insulating long hot water pipes prevents unnecessary energy loss.
1. Optional: fit a temperature gauge (12) so you can check the temperature of the
tap water.
2. Fit the T&P valve (3).
3. Fit a stop valve (11) in the hot water outlet pipe for servicing.
Circulation pipe
See (C) in the installation diagram (2.1 "Installation diagram").
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).
4. Connect the circulation pipe according to the installation diagram (2.1 "Installation
diagram").
