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

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.

= A room sealed appliance designed for connection via
ducts to a horizontal or vertical 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 down stream of
the combustion chamber.
