cleaning is recommended.

MAINTENANCE

The appliance is finished in vitreous
enamel. To clean the surfaces simply
wipe over with a dry cloth. Abrasive
pads and scouring cleaners must not
be used as these will damage the
finish. Care should be taken not to
knock the enamel with hard objects as
it will chip.

Cleaning the Glass

The glass in the doors is a special
ceramic glass which is able to
withstand high temperatures. Before
cleaning the glass open the doors and
allow them to cool. Clean the glass
using a damp cloth and then wiping
over with a dry cloth. Any stubborn
deposits on the glass may be removed
with a proprietary stove glass cleaner
or ceramic hob cleaner. Some deposits
on the glass may be burnt off simply
by running the fire at a fast rate for a
few minutes. Do not use abrasive
cleaners or pads as these can scratch
the surface which will weaken the
glass and cause premature failure.

When not in use

If the fire is going to be out of use for
a long period, (for instance in the
summer,) then to prevent condensa-
tion, and hence corrosion, the
thermostat should be left at the
maximum setting and the main doors

left ajar. It is also advisable to sweep
the chimney and clean out the fire.
Spraying the inside of the doors and
firebox with a light oil, such as
WD40, will also help to keep all
internal parts working well.

After long periods where the fire has
been out of use, the chimney and
appliance flueways should be cleaned
before lighting.

Door Seals

For the fire to operate correctly it is
important that the door seals are in
good condition. Check that they do
not become worn or frayed and
replace them when necessary.

Servicing

It is recommended that the fire is
serviced once a year to keep it in first
class working order. After cleaning
out the firebox thoroughly, check that
all internal parts are in good working
order, replacing any parts that are
beginning to show signs of wear.
Check that the doors seals are in good
condition and that the doors seal
correctly. Check the operation of the
thermostat, both when cold and hot. A
servicing guide, TIS 48. is available
on request.

CHIMNEY SWEEPING

The chimney should be swept at least
twice a year. In most installations it
will be possible to sweep the chimney
through the appliance.

First remove the front firebars and the
throat plate. Then sweep the chimney
ensuring that soot is removed from all
horizontal surfaces after sweeping.

In situations where it is not possible to
sweep through the appliance the
installer will have provided alternative
means, such as a soot door. After
sweeping the chimney the appliance
flue outlet and the flue pipe
connecting the appliance to the
chimney must be cleaned with a flue
brush.

After clearing any soot from within
the appliance, replace the throat plate
and the front firebars.

Different types of sweep’s brushes are
available to suit different flueways.
For standard brick chimneys a wire
centre sweep’s brush fitted with a
guide wheel is recommended. For
prefabricated insulated chimneys the

manufacturers instructions with regard
to sweeping should be consulted.

TROUBLE SHOOTING

Fire Will Not Burn.

Check that:
a) the air inlet is not obstructed in any
way,
b) that chimneys and flueways are
clear,
c) that a suitable fuel is being used,
d) that there is an adequate air supply
into the room,
e) that an extractor fan is not fitted in
the same room as the appliance.

Fire Blazing Out Of Control.

Check that:
a) the doors are tightly closed,
b) the thermostat knob is turned down
to the minimum setting,
c) the air inlet damper is closed (at
the bottom left of the appliance), and
that it is not prevented from closing
completely by a piece of ash,
d) a suitable fuel is being used,
e) the door seals are in good
condition.

Over-Firing

If the fire is over-fired it will cause
premature failure of the internal fire
parts. Overfiring is occurring when
any internal parts of the fire begin to
glow red. To prevent over-firing
ensure that:
a) the ashpit door is kept tightly
closed at all times,
b) the door seals are kept in good
condition, and that the doors are
sealing correctly,
c) the thermostat on the fire is
working correctly,
d) a suitable fuel is being used,
e) the fire is not fitted onto a heating
system which is too large.

Fume Emission.

Warning Note:
Properly installed and operated this
appliance will not emit fumes.
Occasional fume from de-ashing and
re-fuelling may occur. Persistent
fume emission is potentially
dangerous and must not be
tolerated. If fume emission does
persist then the following immediate
actions should be taken:

A) Open doors and windows to
