COMBUSTION CHAMBERS
COMMISSIONING AND HANDOVER
In order for the stove to perform efficiently and safely there should be an adequate permanent air supply into
the room in which the stove is installed to provide combustion air. This is par�cularly necessary if the room is
double-glazed or a flue draught stabiliser is opera�ng in the same room as the appliance. The provision of air
supply to the stove must be in accordance with current Building regulations Approved Document J. An
opening window is not appropriate for this purpose. Air inlets must be positioned in such a way that they
cannot be blocked. An air inlet may be a vent (the vent must be open and the capacity for the vent sufficient
when the stove is lit) .
Loxton models take all combustion air (primary, secondary & tertiary) from a single 80mm port at the bo�om
rear of the stove, with the door closed the air port supplies all combustion air for the appliance. This port can
be connected to the outside via a 80mm pipe so the appliance does not draw combustion air from the room.
However as this stove needs the door to be ajar when lighting and combustion air is taken from the room when
reloading, Mendip stoves recommends the use of an additional air vent as laid out in Document J.
The stove requires a permanent air vent to the room . This is to provide adequate air supply in order for the
stove to operate safely and efficiently. In accordance with current Building Regula�ons the installer may
have fi�ed a permanent air supply vent into the room in which the stove is installed to provide combus�on
air. This air vent should not under any circumstances be shut off or sealed.
COMBUSTION AIR & PERMANENT AIR VENT
Mendip Stoves are fi�ed internally with vermiculite heat deflec�on panels and baffles process of the
stove. These baffles should not be removed other than for cleaning the stove. Any defec�ve panels should
be replaced, small hairline cracks do not need replacement however these can develop during long term use to
a larger crack, if this passes through the vermiculite to the stove body then the panel must be replaced. When
refuelling your stove place the wood fuel into the chamber (wearing a glove), impact from logs can cause the
heat deflec�on panels to crack
.
Connec�on to chimney
Mendip Stoves are built with a top flue outlet as standard, this can be altered to a rear connec�on by removing
the top collar, rear cover plate then exchanging collar and plate. Care should be taken to ensure an air�ght fit
when refi�ng collar and plate. When installing a rear flue exit model please remove rear cleaning steel plate
inside the flue collar box. A decora�ve cover plate is included in each stove to cover the hole in the convection
top plate. This collar allows connec�on to either a masonry chimney or a prefabricated factory made insulated
metal chimney.
DO NOT OBSTRUCT THE AIR INTAKE
At least 40mm clearance should be le� between the air
intake and the wall
Ensure all loose parts (bricks and grates) are fi�ed in accordance with the instructions given in the instruc�on
booklet. On comple�on of the installation allow a suitable period of �me for any fire cement/silicon and
mortar to cure, a small fire may be lit to check that smoke and fumes are taken from the stove up the chimney
and emi�ed safely into the atmosphere.
Do not run at full output for at least 24 hours a�er this appliance has been installed.
On comple�on of the installation and commissioning ensure that the opera�ng instructions for the stove are
le� with the customer. Ensure to advise the customer on the correct use of the appliance with the fuels likely
to be used in the stove and no�fy them to use only the recommended fuels for the stove. Advise the user
what to do should smoke or fumes be emi�ed from the stove. The customer should be warned to use a
fireguard to BS 8423:2002 in the presence of children, aged and/or infirm persons.
The
direct air intake spigot
(80mm
diameter) to the rear of the stove is
removable with a 2.5mm Allen key.
