brickwork with vermiculite (e.g. micafil or similar) concrete.
Ensure that there are no air pockets. The recommended mix is
six volumes of vermiculite granules to one volume of Portland
cement thoroughly mixed together. Enough water should be
added so that no more than one or two drops of water are
released when a handful of the mixture is squeezed.
After filling with vermiculite flaunch the top of the flue
connector pipe to the chimney with lime mortar.
Make good the holes in the front and side of the chimney
breast making sure that they are completely airtight. A typical
installation is shown in Fig. 11.
In most installations it will be possible to sweep the chimney
through the appliance. If this is not possible then some
alternative means (such as a soot door), must be provided.
The free inset method of installation may be used instead of
infilling. Details are available on request.
Before lighting the fire check the cold setting distance of the
thermostat.
With the control knob at the maximum setting the flap should
be 18 mm from the air inlet as shown in Fig. 12. To adjust the
distance slacken the locking nut and adjust as necessary. When
set correctly re-tighten the locking nut. Ensure that the flap
opens and closes freely as the knob is turned.

FREESTANDING KIT
Fit the side panels and hood onto the appliance. Instructions
for this are enclosed with the panel pack. Replace any internal
parts previously removed.
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. 13.
On completion of the installation and after allowing a suitable
period of time for the fire cement and mortar to dry out, the
fire 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.
The central heating pump should be adjusted to give the
correct water flow against the circuit resistance and the
system should be correctly balanced.
On completion of the installation and commissioning please
leave the operating instructions with the customer and advise
on the use of the appliance and any controls on the system.
A freestanding kit is available. Details of dimensions and
outputs are available on request.
