THROAT PLATE AND
FLUEWAY CLEANING
It is important that the throat plate
and all the appliance flueways are
kept clean. When burning smokeless
fuels they should be cleaned monthly.
When burning other fuels they should
be cleaned at least once a week, and
more frequently if necessary.
The throat plate and flueways may be
cleaned with a low fire still burning.
Use the scraper tool to scrape any
sooty deposits to the front of the plate
until they fall off into the fire.
More soot will be deposited on the
throat plate and in the flueways if the
appliance is run at low levels for long
periods. If this is the case then more
frequent cleaning will be necessary.
SPECIAL POINTS
WHEN BURNING
COAL
When burning housecoal keep the
airwash control at least slightly open
all the time (refer to Fig 2.).
When loading the appliance take care
not to smother the fire, instead fill
the firebox in two stages waiting
between each stage for the flames to
appear above the fire.
After a period of slumbering always
turn the air control up to maximum
and wait until flames appear above
the fuel bed before opening the doors.
Burning coal will produce more soot
deposits than other fuels, especially if
the fire is run at low levels for long
periods. It is therefore vital to clean
the throat plate regularly, daily
cleaning is recommended.
CLEANING AND
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.
The glass in the doors is a zero
expansion ceramic glass which will
not crack due to the heat of the fire.
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 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.
Aerosol spray cleaners should not be
used near the appliance whilst it is
under fire.
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.
After long periods where the fire has
been out of use, the chimney and
appliance flueways should be cleaned
before lighting.
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.
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 fire, 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 fire.
