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.

4. Ensure that the over-run catch
swings freely and easily on its spindle
preventing the fire doors from closing
until the ashpit door has been shut.

COMMISSIONING

On completion of the installation and
after allowing a suitable period of
time for the fire cement and mortar to

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.

THERMOSTAT

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.

ASSEMBLY

Fit the side panels, hood and top grid
onto the appliance. Instructions for
this are enclosed with the panel pack.

Replace any internal parts previously
removed.

PRE LIGHTING

CHECK

Before initial lighting check the

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.
