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

To obtain the fuel consumption in liquid form divide the above
gures 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 certied by a notied body.

The electricity at work regulations, 1989. The manufacturer’s
notes must NOT be taken, in any way, as overriding statutory
obligations.
IMPORTANT. These appliances are CE certied for safety
and performance. It is, therefore, important that no external
control devices, e.g. ue dampers, economisers etc., are
directly connected to these appliances unless covered by
these Installation and Servicing Instructions or as otherwise
recommended by Ideal Boilers in writing. If in doubt please
enquire.
Any direct connection of a control device not approved by Ideal
Boilers could invalidate the certication and the normal appliance
warranty. It could also infringe the Gas Safety Regulations and
the above regulations.
