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 ft
/h - divide the gross heat input (Btu/h)
3
by the gross C.V. of the gas (Btu/ft
c. For m
/h - multiply l/s by 3.6.
