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 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

= 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
2H
= An appliance designed for use on 2nd family gas, Group H
only.
II
2H/3P
= An appliance designed for use on 2nd or 3rd family gases,
Group H or P.
* 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, has been certified by a notified body.
** The value is used in the Irish Government’s Dwelling Energy Assessment
Procedure (DEAP) 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
