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
3
)
c. For m
3
/h - multiply l/s by 3.6

C
33
= 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.
* 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.
