Morso 7440 Instructions For Installation And Use Manual page 22

There are no requirements with respect to specific chimney heights, but a chimney must be
tall enough to provide a good draught, and to ensure that the smoke does not cause any prob-
lems. As a general rule, there will be a satisfactory draught if the chimney extends 4 metres
above the stove and at least 80 cm above the spine of the roof.
If the chimney is located along the side of the house, the top of the chimney should never be
lower than the spine of the roof or the highest point on the roof. Please note that there are of-
ten national and local regulations concerning the location of chimneys in houses with thatched
roofs. Please see section 1.9 on Draught.
The chimney and the flue pipe must be fitted with cleaning doors, which must be at least the
same size as the chimney's aperture area.
The chimney must be accessible for external inspection, and it must be possible to access the
cleaning doors and the chimney if it is to be cleaned from the top (e.g. steel chimneys).
1.6 Connecting the flue pipe
lift the upper cast iron top plate off the stove.
Note: the round cast iron cover plate in the top plate must remain mounted if the stove is
being installed with the flue pipe to the rear, but unscrewed from the upper top plate if the
flue pipe is being installed pointing upwards.
Mounting the flue collar pointing upwards
From the factory, the stove is prepared for installation with the included flue collar pointing
upwards with included screws.
Mounting the flue collar to the rear
With a hammer use light, firm taps to knock out the iron piece on the convection back panel
from the small "bridges" holding the piece in place.
The cover plate for the smoke outlet is unscrewed from the back panel and the fixed onto the
top panel.
Mount the flue collar onto the back panel
Lift the top panel back into place and the round section which is provided can be placed in the
top panel and cover for the blocked off smoke outlet.
the location of the baffle and cast smoke hood
The rear brick and the baffle, which are made from vermiculite, are mounted at the factory.
Make sure that the baffle and rear brick stone are correctly assembled before lighting the
stove.
Fresh air supply
The stove has a factory fitted stub underneath to permit a fresh air connection regardless of
the room in which it is installed.
This allows for a ø100mm pipe connection.
Mounting the fresh air supply to the rear:
With a hammer use light, firm taps to knock out the iron piece on the convection back panel
from the small "bridges" holding the piece in place.
The fresh air stub is removed and the plate part is sawn off at the "bridges" using a hacksaw,
after which the plate part is re-fitted below the stove.
The round plate, which is fixed using two screws to the rear of the stove, is removed and
screwed on below the oven.
The stub is then fitted to the rear of the stove.
If the fresh air supply is to be fitted below the Morsø 7448, the stub is removed and turned
180°, then re-fitted, such that the fresh air supply can be run through the plinth pipe.
However, the fresh air connection can only be installed rearwards on the wall-hung Morsø
22 7470.
