Notes.
To obtain the gas consumption:-
a.
For l/s divide the gross heat input (kW) by
C.V. of the gas (MJ/m
3
)
b.
For ft
3
/h divide the gross heat input (Btu/h)
by C.V. of the gas (Btu/ft

)
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 certificated 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 Ltd.
could invalidate the certification and the
normal appliance warranty. It could also infringe the Gas Safety
Regulations and the above regulations.
