Note. Gas consumption is calculated using a
caloric 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
caloric value:
a. For l/s - divide the gross heat input (kW) by
the gross C.V. of the gas (MJ/m
3
)
b. For Btu/h - multiply the gross heat input (kW)
by 26.8
c. For ft
3
/h - divide the gross heat input (Btu/h)
by the gross C.V. of the gas (Btu/ft
3
)
d. For m
3
/h - multiply l/s by 36

= 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
orices which, in this case, are concentric. The fan is up stream of
the combustion chamber.
I
2H
= An appliance designed for use on 2nd Family gas, Group H only.
* 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 certied by a notied body.
