The fire should be riddled with all
doors shut. Place the tool on the knob
and rotate between the horizontal and
the 45 degree position several times as
shown in Fig. 3.
When burning wood or peat do not
riddle all the ash into the ashpan,
keep a layer about 12 mm (1/2 inch)
thick on the grate.
Caution: when riddling the grate
using solid fuel do not go beyond the
45 degree position as this can cause
the grate to jam.
If jamming does occur then the fire
should be allowed to burn for
approximately half an hour before
riddling the grate again as described
above.
Too much riddling can result in
emptying unburnt fuel into the ashpan
and should therefore be avoided.
Clinker should regularly be removed
from the firebed.
After riddling, the grate should be put
back into the solid fuel or wood
position as required (the tool should
be horizontal for solid fuel or vertical
for wood or peat).
REFUELLING
Keep the firebox well filled (the fuel
may be sloped up from the front
firebars), but do not allow fuel to spill
over the top of the front fire bars.
Take care, especially when burning
wood, that fuel does not project over
the front fire bars or damage to the
glass may be caused when the doors
are closed.
OVERNIGHT
BURNING
Empty the ashpan, if necessary, and
then riddle the fire if you are burning
solid fuel. If the fire is very low then
it may be necessary to add a little fuel
and turn the thermostat control up to
maximum for a brief period until the
fire is burning brightly before filling
with fuel. When burning wood use
large logs overnight as they will burn
more slowly than small ones.
If the central heating pump is off
overnight then the thermostat may be
left at the same setting for both day
and night operation. If the central
heating pump is on overnight then set
the thermostat control to give the
required level of heating.
Some experimentation may be
necessary to find the setting most
suitable for the particular fuel used
and the draw on the chimney.
For overnight burning the fire doors
must be closed.
To revive the fire, empty the ashpan if
necessary, riddle, (when burning solid
fuel), and turn the thermostat control
knob to maximum. When the fire is
burning well load on more fuel as
necessary and turn the control knob to
the desired setting.
When burning wood do not riddle but
simply turn the air control to
maximum until the fire picks up and
then set the air control at the desired
setting and refuel as necessary.
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.
Lower the throat plate using the throat
plate tool. To do this engage the end
of the tool in the throat plate as shown
in Fig.4., pull the plate forward and
then lower it. Use the scraper tool to
push any sooty deposits up the plate
until they fall off the back and into the
fire. While the throat plate is in the
lowered position also scrape any soot
deposits from the sides and top of the
firebox.
Ensure that soot deposits are
not allowed to build up on the side
boiler faces because if the throat
plate becomes tight between the
faces this can cause it to fail
prematurely.
Return the throat plate to its correct
position - raise the front of the plate,
push it back and then lower it onto the
retaining lugs. The upper set of lugs
are for use when burning smokeless
fuels and the lower set of lugs are for
use when burning coal, wood or peat
(see Fig. 4.).
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
throat plate in the lower position and
the secondary air control open all the
time (refer to Fig 4. and 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
