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, has been certified by a notified body.
Gas consumption is calculated using a calorific value of
38.7 MJ/m
(1038 Btu/ft
) gross or 34.9 MJ/m

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 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
)

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.
