ii) Connecting into the waste system of the building such as

a washing machine or sink trap. The connection must be

upstream of the washing machine/sink (If the connection

is down stream of the waste trap then an additional trap

giving a minimum water seal of 75 mm and an air break

must be incorporated in the pipe run, as above.

iii) Terminating into a gully, below the grid level but above the

water level.

iv) Into a soakway.

externally, then it should be kept to a minimum and be

insulated with a waterproof insulation and have a continuous

fall.

OINTS

These must be fitted at all high points where air naturally

collects and must be sited to facilitate complete filling of the

system.

The appliance has an integral sealed expansion vessel to

accommodate the increase of water value when the system is

heated.

It can accept up to 7 l (1.5 gal) of expansion water. If the

heating circuit has an unusually high water content, calculate

the total expansion and add an additional sealed expansion

vessel with adequate capacity.

There must be no direct connection to the mains water supply

even through a non-return valve, without the approval of the

Local Water Authority.

ILLING

A method for initially filling the heating system is supplied with

the connection kit. The filling loop is connected between the

cold water inlet and the central heating flow connections, and

incorporates a non-return valve. To operate the filling loop, it

is necessary to open both quarter turn handles, once the

required pressure has been achieved, close both handles and

disconnect the hose in accordance with water byelaws. N

The installer should ensure that there are no leaks as

frequent filling of the heating system can lead to premature

scaling of the main exchanger and failure of hydraulic

components.

The domestic water must be in accordance with the relevant

recommendation of BS 5546:1990. Copper tubing to BS EN

1057:1996 is recommended for water carrying pipe work and

must be used for pipe work carrying drinking water, a scale

reducer should also be used to reduce the risk of scale

forming in the domestic side of the heat exchanger.

EATING

In the event of an under floor heating system, fit a safety

thermostat on the boiler flow (see Section 2.10). This

thermostat should be positioned at a safe distance from the

boiler to ensure the correct operation of the same. If the

thermostat is positioned too close to the boiler, the water

remaining in the boiler after domestic hot water has been

drawn will flow into the central heating system and may cause

the thermostat contact to open without there being any real

danger of the system being damaged, this would lead to a

boiler shutdown both in D.H.W. mode and C.H. mode, and the

error code "E08" would be displayed; boiler operation resumes

automatically when the thermostat contact closes on cooling.

Should the thermostat fail to be installed as recommended, the

under floor heating system can be protected by installing a

thermostatic valve upstream from the thermostat in order to

prevent the flow of excessively hot water towards the system.
