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

) 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 3.6
Key to symbols
GB = United Kingdom IE = Ireland (Countries of destination)
PMS = Maximum operating pressure of water
C13 C33 C53 = 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.
Table 1 - General Data
*Required for maximum ow rate. Boiler operates down to 2 l/min DHW delivery
** In areas of low water pressure the DHW restrictor can be removed
