NOx classification
*
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.
Note. Gas consumption is calculated using a
calorific value of 38.7 MJ/m
gross or 34.9 MJ/m (935 Btu/ft
3
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 /h - divide the gross heat input (Btu/
h) by the gross C.V. of the gas (Btu/ft
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.

Key to symbols
GB = United Kingdom IE = Ireland (Countries of destination)
PMS = Maximum operating pressure of water
C C C = 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.
