The boiler is an atmospheric type boiler. This means
that the air contained in the room where the boiler
is installed, is used for burner combustion. It is es-
sential, therefore, that installation of the boiler is in
strict compliance with rules and standards currently
in force for this type of boiler.
Both the central heating and domestic hot water
temperature are user adjustable from the boiler
Part No. control panel, see diagram1.
XXXXX
Electrical components have been tested to meet
the equivalent requirements of BEAB.
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
circulation. The pump, expansion vessel and asso-
ciated safety devices are all fitted within the boiler.
The installation must be carried out by a compe-
tent person in accordance with the relevant re-
quirements of The Building Regulations, The Water
Byelaws, The Building Standards (Scotland) Regu-
lations and any applicable local regulations.
