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
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.
Electricity supply and Fuse rating for pumps etc. refer to manufacturer's instructions.
