English RAIS - manual for

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 either 150 mm (6”) in diameter, or 129 mm (5”) 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.
