Condensation drain
1. Fit a sloping waste water pipe to the condens trap (13) for condensation drainage
and connect this via an open connection to the waste water discharge.

If the condensation drain is not fitted to the waste water discharge using an open
connection, this can cause faults.

Vented water connections

Warning
The installation should be carried out by a competent person, in compliance with general
and locally applicable regulations.
Cold water side
See (A) in the installation diagram (see section 7.3).
1. Fit an approved stop valve (4) on the cold water side between the cold water head
tank (18) and the water heater, as required by applicable regulations.
Hot water side
See (B) in the installation diagram (see section 7.3).
Note
Insulating long hot water pipes prevents unnecessary energy loss.
1. Fit the T&P valve (3).
2. Optional: fit a temperature gauge (12) so you can check the temperature of the tap
water.
3. Fit a stop valve (4) in the hot water outlet pipe for servicing.
4. If a circulation pipe is required, continue by installing the circulation pipe (see section
7.4.1.3).
Circulation pipe
See (C) in the installation diagram (see section 7.3).
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 (see section 7.3).
Condensation drain
1. Fit a sloping waste water pipe to the condens trap (13) for condensation drainage
and connect this via an open connection to the waste water discharge.
Caution
If the condensation drain is not fitted to the waste water discharge using an open
connection, this can cause faults.
