The value is used in the UK Government's Standard Assessment Procedure (SAP) for energy rating of dwellings.
The test data from which it has been calculated have been certified by a notified body.
CAUTION.
To avoid the possibility of injury during the installation, servicing or cleaning of
this appliance, care should be taken when handling edges of sheet steel components.
Note.
Gas consumption is calculated using a calorific value of 38.7
MJ/m
3
(1038 Btu/ft
3
) gross or 34.9 MJ/m
3
(935 Btu/ft
3
) nett. To
obtain the gas consumption at a different calorific value:-
a.
For l/s - divide the gross heat input (kW) by the gross C.V.
of the gas (MJ/m
3
)
b.
For ft
3
/h - divide the gross heat input (Btu/h) by the gross
C.V. of the gas (Btu/ft

= A room sealed appliance designed for connection
via ducts to a horizontal terminal which admits
fresh air to the burner and discharges the
products of combustion to the outside through
orifices which, in this case, are concentric. The
fan is up stream of the combustion chamber.
