Water Treatment

The boiler is equipped with an aluminium alloy main heat

exchanger.

The detailed recommendations for water treatment are given in

BS 7593:1992 (Treatment of water in domestic hot water central

heating systems); the following notes are given for general

guidance:

- If the boiler is installed in an existing system, any

unsuitableadditives must be removed;

- Under no circumstances should the boiler be fired before

thesystem has been thoroughly flushed; the flushing

procedure must be in line with BS7593:1992.

We highly recommend the use of a flushing detergent

appropriate for the metals used in the aluminium alloy circuit.

These include (Fernox Superfloc, BetzDearborn Sentinel

X300 or X400 or Salamander System Cleanser), whose

function is to dissolve any foreign matter that may be in the

system;

In hard water areas or where large quantities of water are in
