The Chimney - Morso 3440 Instructions For Installation And Use Manual

1.5 The chimney

Only if National or Local Regulations permit are you permitted to connect a stove into a chim-
ney that is shared by another appliance. YOU MUST be aware of any applicable Regulations
in this respect.
The wood-burning stove must never be connected to a chimney to which a gas-burning stove
or appliance is connected. An efficient modern stove places heavy demands on the chimney,
and you should have the chimney regularly swept and inspected by your approved chimney
sweep. The cross-sectional area of the chimney (at its narrowest point) must comply with Na-
tional and Local Building Regulations. Generally, the area needed for a Morsø wood-burning
stove installation should measure at least 175 cm2 (150 mm diameter).
An over-sized chimney is generally hard to keep warm and results in poor draft. In cases
where there is an oversized masonry chimney, it is recommended that the chimney be lined
using an appropriate chimney lining system with the correct internal diameter.
With respect to the chimney termination, all chimneys should terminate in accordance with
National and Local Building Regulations. Note that National and Local Regulations also apply
with regard to the placement of chimneys and flues in connection with thatched roofs. See
the section on Draft Conditions, 1.9.
The chimney or flue system must be equipped with access doors for inspection and cleaning.
The size of the cleaning door in the chimney must at least equal to that of the cross-sectional
area of the chimney. In the event that a chimney fire occurs resulting from faulty operation or
prolonged use of damp wood fuel, close the air vents completely and contact your local fire
department immediately.
1.6 Fluepipe connections
The stove comes standard with a smoke outlet (1) and a ball lock (3) at the top, and a cast-
iron cover mounted on the cast-iron back panel behind the convection back panels. If you
want to install the stove with the smoke outlet at the back, knock the iron plates on the con-
vection back panels out of the small "bridges"
which hold the plates in place, using light,
steady hammer taps. Unbolt the cast-iron
cover from the back panel by turning it anti-
clockwise, and install it in the top plate by
pushing it down and turning it clockwise. The
cover can work as a clean-out cover, making
access easier for the annual cleaning of the
stove. Centre the smoke outlet in the hole at
the back of the stove and bolt it securely in
place with the bolts and clamps provided. The
ball lock is not used, if the stove is fitted with
the outlet at the back.
Please note: During firing, the cleaning val-
ve (2) must always be installed correctly in
the baffle as the top cover may otherwise
overheat and sustain permanent damage.
