Installation
Instructions
Chimney
The himney height and the position of the
himney terminal should onform to Building
Regulations.
Che k that the himney is in good ondition,
dry, free from ra ks and obstru tions.
The diameter of the flue should not be less than
125mm and not more than 200mm.
If any of these requirements are not met, the
himney should be lined by a suitable method.
If there is no existing himney then either a
prefabri ated blo k himney in a ordan e with
Building Regulations Approved Do ument J, or a
twin-walled insulated stainless steel flue to BS
EN 1856 an be used. These himneys must be
fitted in a ordan e with the manufa turer’s
instru tions and Building Regulations.
If the himney is believed to have previously
served an open fire installation, it is possible
that the higher flue gas temperature from the
stove may loosen deposits that were previously
firmly adhered, with the onsequent risk of flue
blo kage. It is therefore re ommended that the
himney be swept a se ond time within a
month of regular use after installation.
If you have any doubts about the suitability of
your himney, onsult your lo al
dealer/sto kist.
Connection to the Chimney
The himney must be swept before onne tion
to the stove.
An existing firepla e opening an be bri ked up
or sealed with a register plate.
A short length of flue pipe of minimum 125mm
internal diameter may then be used to onne t
the stove to the himney. This flue pipe should
be made of 316 grade stainless steel or vitreous
enamelled steel, nominal thi kness 1.2mm.
Ensure that the pipe end is no loser than
76mm to the himney walls.
The length of any horizontal run of flue pipe
must not ex eed 125mm.
It is essential that all onne tions between the
stove and himney-flue are sealed and made
airtight.
Both the himney and flue pipe must be
a essible for leaning and if ANY part of the
himney annot be rea hed through the stove
(with baffle removed), a soot door must be
fitted in a suitable position.
Flue Draught
If the draught ex eeds the re ommended
maximum, a draught stabiliser must be fitted so
that the rate of burning an be ontrolled and
to prevent over firing.
If the reading is less than the re ommended
minimum then the performan e of the
applian e will be ompromised.
The flue draught should be he ked under fire
at high output.
