& C
32
=
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
down stream of the combustion chamber.
C
72
= A room sealed appliance designed for connection via
concentric vertical ducts and a draught diverter located
in the roof space to a secondary flue. The combustion
air is taken from the roof space. The fan is down
stream of the combustion chamber.
I
2H
= An appliance designed for use on 2nd Family gas,
Group H only.
CAUTION.
To avoid the possibility of injury during the installation, servicing or cleaning of this
appliance, care should be taken when handling edges of sheet steel components.

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

)

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.
