flush with the hearth.
If the optional convection ducts are used or if it is
necessary to gain access to the flue pipe when fitting the
fire then it will be necessary to make a hole in the
chimney breast above the fire opening. See Fig.2.
FITTING THE CONVECTION
CASING AND FLUE PIPE
It is important to have a layer of insulation around the
convection casing. This may consist of either a layer of
mineral fibre or a vermiculite concrete mix. Vermiculite
must be used in situations where the optional convection
ducts are being used. Two typical installations are shown
in Fig. 3. and Fig. 4.
Apply a thin layer of fire cement onto the top flange of
the flue connecting ring. Fit the flue connecting ring into
the convection casing with the top flange of the flue ring
fitting onto the underneath of the top of the convection
casing. Ensure that the bolts are well tightened. If
rockwool insulation is being used then wrap this around
the sides and back of the convection casing. Slide the
convection casing, complete with flue connecting ring,
into position in the opening and make the flue connec-
tion. This may consist of 175mm dia (7 inch) flue pipe in
either 1.0mm thick stainless steel or cast iron, alterna-
tively the connection may be made simply by flaunching
the convection casing to the chimney walls using lime
mortar. It is vital that the connections at both ends of the
flue pipe are well sealed. Use fire cement and glass fibre
rope.
Make good the opening at the sides of the convection
casing ensuring that a good seal is made with the side
flanges. If you are using the vermiculite method of
insulating the convection casing then fill in the space
between the casing and the brickwork and around the flue
pipe with a vermiculite or perlite concrete mix. The
recommended mixture is 6 parts of vermiculite or perlite
to 1 part of cement. Add only enough water so that a few
drops are released when a handful of the mixture is
squeezed.
Make good the opening above the the convection casing
ensuring that it is well sealed.
If, for any reason, it is not going to be possible to sweep
the chimney through the appliance then a soot door must
be fitted.
FITTING THE STOVE
Carefully slide the stove into the convection casing until
the flue outlet lines up with the flue collar. Working
through the stove, place the rope ring into the gap
between the stove and the flue connection ring, and then
fit the bolts through the holes in the top of the stove and
into the flue ring. Apply a bead of fire cement to the gap
between the flue ring and the stove, and tighten the bolts.
Check that the flue pipe is not obstructed or restricted in
any way and that all joints are well sealed.
MAINS SUPPLY FOR THE FANS.
The adaptor provided must be connected to a suitable
mains socket. For the U.K. adaptor this is a 240 volt 50
Hz. a.c. supply. For the European adaptor this is a 220
volt 50 Hz. a.c. supply.
THE MAINS ADAPTOR MUST BE USED.
DO NOT CONNECT A MAINS SUPPLY
DIRECTLY TO THE FIRECLASS.
CONNECTING THE POWER.
Plug the connector from the adaptor into the socket on
the left-hand side panel. Cable clips or conduit may be
used to retain the wire if desired. If it is necessary to
extend the wire then ensure that the correct polarity is
maintained. The large pin on the plug must be positive.
There is a thermal cut out linked into the fan control.
This means that the fans will not operate until the stove
warms up.
ADJUSTMENTS
Replace any internal parts previously removed.
Please check that the door is in alignment and is sealing
well. The door may be adjusted by slackening the screws
that hold the left hand side panel and adjusting the
position as required. To adjust the door catch slacken the
locking nut and screw in or out as required. Tighten the
locking nut after adjusting.
PRE LIGHTING CHECK
Before initial lighting check the following points:
1. The bottom grate bars must all be fitted and should
move freely and easily when the riddling mechanism is
operated.
2. The plates round the sides and back of the grate must
be in position and sitting correctly.
3. The throat plate must be fitted in the roof of the
appliance - see Fig. 5.
COMMISSIONING
On completion of the installation and after allowing a
suitable period of time for the fire cement and mortar to
dry out, the stove should be lit and checked to ensure that
smoke and fumes are taken from the appliance up the
chimney and emitted safely. Also check all joints and
seals and ensure that the fans operate correctly.
On completion of the installation and commissioning
please leave the operating instructions with the customer
and advise on the use of the stove.
