HEALTH AND SAFET Y PRECAUTIONS
SYSTEM
Please take care when installing the boiler that the requirements of
the Health and Safety at Work Act 1974 are met.
Some types of fire cement are caustic and should not be allowed to
come into contact with the skin. In case of contact wash with plenty
of water.
If there is a possibility of disturbing any asbestos in the course of
installation then please use appropriate protective equipment.
In addition to these instructions the requirements of BS.8303 and
BS.6461 Pt 1&2; 1984 must be fulfilled. Local Authority Bylaws and
Building Regulations, including those referring to National and
European Standards regarding the installation of Solid Fuel burning
appliances, flues and chimneys must also be observed.
The Charnwood Flue Boiler is designed to be used with a Charnwood
stove. It can be used as a ‘stand alone’ heating system for domestic
hot water and/or radiators, or as part of a larger heating system.
There are a variety of ways in which it is possible to link up this boiler
with a larger system, and some of these are shown in Figs 2 to 4.
When a small stove such as the Cove 1 and a Flue Boiler FB100 are
used, a simple system as shown in Fig 2 may be used. A larger size of
hot water cylinder (i.e. above 115 Litres) is usually required to reduce
the possibility of boiling, since on this system no heat leak radiator is
shown. If the stove is to be run near its full capacity, then a heat leak
radiator should be considered.
If a larger stove such as the Island 3 and Flue Boiler FB300 are used,
then extra radiators may be added to the system as shown in Fig 3.
These are controlled by a high limit pipe thermostat mounted on the
This is particularly
necessary if the room is double glazed. It must be positioned such
that it is not liable to blockage.
Careful consideration must be given to the siting of the stove and
boiler, since the Boiler Access door MUST be accessible in order to
sweep the chimney. This means that there must be at least 750mm
free space above the top of the stove. The flow pipe connected to the
top of the boiler must rise continuously up to the vent. It must not
drop down and nominally horizontal runs should have some upward
slope.

There must be an adequate air supply into the room in which the
appliance is installed to provide combustion air. The combustion air
supply must be via a permanently open vent.
