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
or 34.9 MJ/m
(935 Btu/ft
) 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
b. For Btu/h - multiply the gross heat input (kW)
by 26.8
c. For ft
/h - divide the gross heat input (Btu/h)

by the gross C.V. of the gas (Btu/ft
d. For m

Key to symbols
GB =

PMS = Maximum operating pressure of water
= A room sealed appliance designed for connection via ducts to a
C13 C33 C53
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.
