Graphite GR910-B, Instruction Manual

BOILER STOVE SYSTEMS – 

SPECIFIC SAFETY ISSUES

• If there is a possibility that part of the heating 
system may be frozen you should not light the stove 
until you are confident that the system is free of ice, 
has no leaks and that the water can fully circulate.
• This stove requires a dedicated non-closable air vent 
of the appropriate size – see page 5.
• The system should not rely solely on gravity fed 
circulation but must also incorporate a circulation 
pump. 
• This stove should not be connected directly to a 
sealed or pressurised system without including a 
safety ‘buffer’ between the systems such as a thermal 
store, heat exchanger or specialist link-up component. 
This will also help neutralise any pipe size difference 
between the two systems which could adversely affect 
performance.
•The cold feed and open vent flows must not be 
fitted with any manual or automatic valve. The system 
flow must not be able to be ‘closed off’ so that there 
is always a clear flow route from the stove to the 
system’s open vent
• In the event of a power cut or circulation pump 
failure your stove will continue to produce hot 
water which could be potentially dangerous. Your 
system design should therefore provide for the safe 
dissipation of excess hot water through a heat loss or 
heat leak radiator. 
• Motorised valves must revert to the open position in 
the event of a power failure. This will allow heat to be 
safely dissipated through the system’s natural gravity 
circulation process.
• Although it is common practice for heat leak 
radiators to be located in an upstairs bathroom it is 
worth noting that on some boiler stove systems the 
heat leak radiator can get very hot and therefore we 
recommend installing a low surface temperature type 
radiator and / or locating it where young children or 
the infirm won’t accidentally come into contact with it
• The heat output to water from this boiler stove must 
not be significantly greater than any potential usage. 
The system’s heat release feature, especially if linked, 
must be sufficient to prevent the system from over-
heating.
• The system design must incorporate a drain point, 
preferably near the boiler stove, and be sufficient 
to empty the system of any residue water during 
maintenance or removal.
• All electrical connections, for example to system 
valves, the circulating pump and the link-up 
component must comply with current Building 
Regulations. Ensure that the pipework is correctly 
earthed. See page 8 and 24 for relevant regulations. 
• The mains water connection to the system must 

7

comply with local water authority regulations in order 
to safeguard water quality and public health – see 
page 8 and 24.
• The hot water cylinder thermostat should be set at 
60ºC (and tested) to prevent scalding – see page 24. 
 

HEALTH & SAFETY

During the installation of this stove and any related 
building works you must comply with any current 
Health & Safety at Work regulations. Always use  
protective gloves and use the tool when adjusting the 
air controls. When using fire cement always follow the 
manufacturer’s instructions. 
 

ASBESTOS

This stove does not contain Asbestos. However, check 
that there is no possibility of disturbing any asbestos  
based materials during its installation. You may 
intend removing an older appliance prior to installing 
your new stove, and you should be aware that the 
old appliance or installation could incorporate heat 
protective asbestos sheet. Use appropriate protective 
equipment and seek specialist guidance at  

www.hse.gov.uk/asbestos

 – do not underestimate the 

potential dangers of Asbestos. 
 

FIRE CEMENT

Some types of fire cement are caustic and should 
not be allowed to come into contact with the 
skin. Protective gloves and glasses should be worn 
when applying fire cement. In case of contact wash 
immediately with plenty of water. Always read and 
follow the fire cement manufacturer’s instructions. 
Care should also be taken to avoid unnecessary 
contact between the stove’s surfaces and the fire 
cement as this could damage the paintwork. Any 
excess fire cement should be quickly removed before 
it hardens.  
 

HANDLING

The Graphite Boiler stove is extremely heavy and  
therefore adequate facilities must be available for its 
safe loading, unloading and site handling. 
 

METAL PARTS

When installing or servicing this stove care should be 
taken to avoid the possibility of personal injury from 
the stove’s metal parts. 
 

BUILDINGS INSURANCE

It is a requirement by some building insurance  
companies to inform them of the installation of a new 
fixed heating appliance and a relevant certificate of 
compliance produced.
