In order for the stove to perform efficiently and safely there should be an adequate air supply into the room in which the
stove is installed to provide combustion air. This is particularly necessary if the room is double-glazed or a flue draught
stabiliser is operating 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).
The Ashcott models take all combustion from a single 100mm port on the back of the stove, with the door closed the air
port supplies all combustion air for the appliance. This can be connected to the outside via a 100mm pipe so the appliance
does not draw air from the room. However, the Ashcott must have an independent air vent as laid out in Building Regulations
Approved Document J for when the stove is being reloaded.
The hearth should be able to accommodate the weight of the stove and its chimney if the chimney is not independently
supported. The Ashcott stove has been tested and is suitable to be installed on a 12 mm non combustible plate such as 12
mm glass plates . Installation of all hearths should comply in size and construction so that it is in accordance with the provisions
of the current Building Regulations Approved Document J.
The clearance distances to combustible material beneath, surrounding or on the hearth and walls adjacent to the hearth
should comply with the guidance on the separation of combustible material given in Building Regulations Approved Document
J and also in these stove instructions.
If the stove is to be installed on a wooden floor, it must be covered with a non-combustible material at least 12 mm thick,
in accordance with Building Regulations Approved Document J, to a distance of 30 cm in front of the stove and 15 cm to
each side measuring from the door of the combustion chamber.

COMBUSTION AIR
COMBUSTION CHAMBERS
Mendip Stoves are fitted internally with a formed vermiculite combustion chamber, the panels that form the chamber are
designed to ensure the maximum efficiency of the stove and are an integral part of the clean burn process. The vermiculite
parts should not be removed other than for cleaning the stove. Any defective panels should be replaced, (small hairline
cracks do not need replacement), however, 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 deflection panels to crack
.
Connection to chimney
Mendip Stoves are built with a top flue outlet as standard, this can be altered to a rear connection by removing the top
collar, rear cover plate then exchanging collar and plate. Care should be taken to ensure an airtight fit when refitting collar
and plate. A decorative cover plate is included in each stove to cover the hole in the convection top plate. This collar allows
connection to either a masonry chimney or a prefabricated factory made insulated metal chimney.
COMMISSIONING AND HANDOVER
Ensure all loose parts (bricks and grates) are fitted in accordance with the instructions given in the instruction booklet. On
completion of the installation allow a suitable period of time for any fire cement and mortar to dry out, a small fire may be
lit to check that smoke and fumes are taken from the stove up the chimney and emitted safely into the atmosphere. Do not
run at full output for at least 24 hours.
On completion of the installation and commissioning ensure that the operating instructions for the stove are left 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
notify them to use only the recommended fuels for the stove. Advise the user what to do should smoke or fumes be emitted
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.
