Cold Water Connection:

The water heater is intended to be

permanently connected to the water

supply main.

An approved isolating valve, non-

return valve, line strainer (optional but

recommended) and union must be

fitted between the water supply main

and either of the RP¾"(DN20) sockets

marked "INLET" at the bottom of the

water heater.

The other inlet socket is to be plugged

with one of the brass plugs supplied

loose with the water heater. Ensure a

sealing material is applied to the brass

plug to prevent water leaks.

All fittings must be approved by the

relevant Authority. Plastic pipes or

fittings shall not be used between the

isolating valve and the inlet.

See the diagram below for details.

Note: a combined isolating valve/non-return valve/line strainer may be used.

The expansion control valve is only required where local regulations demand, although it is

recommended in areas where the water saturation index is greater than 0.40.
