RAIS Q-20 Manuel D'utilisateur page 8

ENGLISH
A single wall metal fluepipe is suitable for connecting the stove to the chimney but is not
suitable for using for the complete chimney. The chimney and connecting fluepipe must
have a minimum diameter of 150 mm and its dimension should be not less than the size
of the outlet socket of the stove which is 150 mm in diameter. Any bend in the chimney
or connecting fluepipe should not exceed 45°. 90°bends should not be used.
Combustible material should not be located where the heat dissipating through the walls
of fireplaces or flues could ignite it. Therefore when installing the stove in the presence
of combustible materials due account must be taken of the guidance on the separation
of combustible material given in Building Regulations Approved Document J and also in
these stove instructions.
If it is found that there is excessive draught in the chimney then either an adjustable flue
damper or alternatively a draught stabiliser should be fitted. The adjustable flue damper
should not close off the flue entirely but should in its closed position leave a minimum
continuous opening free area of at least 20 % of the total cross sectional area of the flue
or fluepipe.
Adequate provision e.g. easily accessible soot door or doors must be provided for sweep-
ing the chimney and connecting fluepipe.
You should also familiarise yourself with the draught conditions for chimneys with 2 flues.
The flue outlet spigot is 150 mm in diameter.
For strong draughts, the chimney or flue should be fitted with a draught stabiliser. In
which case, it is important to ensure that there is a free flow-through area of minimum
20 cm² when the regulating gate is shut. Otherwise, the fuel energy may not be used
optimally. If, at any time, you are unsure about the condition of the chimney, you should
contact a chimney sweep.
Remember that access to the access door should be kept clear.
