. For l/s divide the gross heat input (kW) by the gross C.V. of the
gas (MJ/m

divide the gross heat input (Btu/h) by the gross C.V. of
the gas (Btu/ft

/h multiply l/s by 3.6.
Propane gas consumption is calculated using a calorific value of

To obtain the fuel consumption in liquid form divide the above
figures by 270.
* The value is used in the UK Government’s Standard Assessment
Procedure (SAP) for energy ratings of dwellings. The test data from which
it has been calculated have been certified by a notified body.

obligations.
ImPoRtAnt
. These appliances are CE certified for safety
and performance. It is, therefore, important that no external
control devices, e.g. flue dampers, economisers etc., are
directly connected to these appliances unless covered by
these Installation and Servicing Instructions or as otherwise
recommended by
Ideal Stelrad Group
in writing. If in doubt
please enquire.
Any direct connection of a control device not approved by
Ideal Stelrad Group
could invalidate the certification and the
normal appliance warranty. It could also infringe the Gas Safety
Regulations and the above regulations.
