Table 1 - General Data
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 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 up stream of
the combustion chamber.
I

= 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 certified by a notified body.
*Required for maximum flow rate. Boiler operates down to 2 l/min DHW delivery
** In areas of low water pressure the DHW restrictor can be removed
