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
3
)
c. The appliance is preset at the factory to the highest
nominal rating.
Key to symbols
GB = United Kingdom IE = Ireland
(Countries of destination)
PMS = Maximum operating pressure of water
C
11
= A room sealed appliance designed for connection via
ducts to a horizontal terminal, which admits fresh air to
the burner and discharges the products of combustion
to the outside without a fan in the combustion products
circuit.
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.
