MINIMUM DISTANCE TO COMBUSTIBLE MATERIALS
Note: combustible material refers to any material that will degrade when
subjected to heat e.g. plaster. Due to the heat of a hot stove, a suitable fire
guard should always be used to provide additional protection. Never allow
young children to be left unsupervised in a room containing a hot stove.
Note; If in doubt, refer to Building Regulations 2000 Approved Document “J”.
THE CHIMNEY
The stove is supplied with a flue pipe connector for top mounting with the
fixing screws supplied. The stove should never be connected to a shared
chimney/flue system.
Flue pipes with a smaller cross-sectional area than that of the stove outlet
should never be used. Flue pipes must not project into the chimney
connector, such as to cause a restriction to the gas flow.
Sizes of flues in chimneys are stipulated in Table 2 of the Building Regulations
2000 Approved Document “J” as follows:
1. Stoves under 20kW rated output which burn smokeless or low volatile fuel
require a minimum flue size of 125mm diameter (or rectangular flues
having the same cross-sectional area and a minimum dimension not less
than 100mm for straight flues or 125mm for flues with bends or offsets.
2. Stoves of up to 30kW rated output burning any fuel require 150mm
diameter (or rectangular flues having the same cross-sectional area and a
minimum dimension not less than 125mm.
Liners should be installed in accordance with their manufacturers instructions.
Appropriate components should be selected to form the flue without cutting
and to keep joints to a minimum. Bends and offsets should be formed only
with the matching factory-made components. Liners need to be placed with
the sockets or rebate ends uppermost to contain moisture and other
condensates in the flue. Joints should be sealed with fire cement, refractory
mortar or installed in accordance with their manufacturers instructions. Ensure
the joints are completely sealed as air leakage will lead to poor
performance. Avoid having more than two bends in the flue system. Any
offset between bends should be minimised and the flue should be equipped
with suitable access doors for inspection & cleaning. For further detail refer to
Building Regulations document “J”
A range of suitable flue pipes, cowls and fire cement are available from your
Clarke dealer.
Special methods are required when passing through a wall or ceiling. Please
refer to your local building regulations and/or fire department. Refer to
Building Regulations Document “J”.
THIS STOVE MUST NOT BE INSTALLED INTO A CHIMNEY THAT SERVES ANY
OTHER HEATING APPLIANCE. THERE MUST NOT BE AN EXTRACTOR FAN
FITTED IN THE SAME ROOM AS THE STOVE, AS THIS CAN CAUSE THE
STOVE TO EMIT FUMES INTO THE ROOM.
