Note.
Natural gas consumption is calculated using a calorific value of
37.8MJ/m

(1038Btu/ft
3
) gross or 34 MJ/m
3
(910 Btu/ft
3
) nett at
15ºC and 1013.25 mbar.
a
. For l/s divide the gross heat input (kW) by the gross C.V. of
the gas (MJ/m
3
)
b. For ft/h
3
divide the gross heat input (Btu/h) by the gross C.V.
of the gas (Btu/ft
3
).
Propane gas consumption is calculated using a calorific value of
95.7 MJ/m

(2500 Btu/ft.
3
) gross or 88.0 MJ/m
3
(2300 Btu/ft.
3
) net
at 15ºC and 1013.25 mbar.
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.

HEALTH & SAFETY DOCUMENT NO. 635
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 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 Caradon Ideal Limited in writing. If in doubt
please enquire.
Any direct connection of a control device not approved by
Caradon Ideal Limited could invalidate the certification and the
normal appliance warranty. It could also infringe the Gas Safety
Regulations and the above regulations.
