Domestic hot water demand always has priority
over heating demand.
The boiler is designed for use as part of a sealed
water central heating system with fully pumped cir-
culation. The pump, expansion vessel and associ-
ated safety devices are all fitted within the boiler.
The boiler can be installed against either an exter-
nal wall or on an adjacent inside wall, that is, the
flue system will pass directly to the rear or to either
side to the terminal fitted on the outside wall face.

tent person in accordance with the relevant re-
quirements of The Building Regulations, The Water

lations and any applicable local regulations.
