This item is heavy and may need two hands - wear
gloves.
Due to an accumulation of pieces of stone, clinker and
shale etc, it may not be possible to pass them through the
grate when riddling, and may even cause jamming.
Allow the fire to burn out and cool down, then open
the ashpit door and remove ashpan.
1. Engage the curved end of the grate assembly removal
tool, within the groove in the centre of the bottomgrate
support, (See Fig. 6).
2. Raise the front end of the tool slightly and draw the tool
forwards so that the grate support moves forward over
its support lugs.
3. Taking the weight of the grate assembly lower the front
of the removal tool and withdraw the complete grate
assembly. Clean out.
4. Replace in reverse order of withdrawal ensuring the
grate support is positively located on the front points of
the ashpit.
The amount of clinker formation is dependent on the
burning rate and should be checked weekly for any build-
up. Excessive build-up will lead to a fall off burning rate,
and reduction in life of the bottomgrate: so the
bottomgrate should be kept clear of clinker.
Two bottomgrates are available for use. One has a slightly
raised centre and a serrated edge (See Fig. 6). This is for
burning coal and manufactured briquetted smokeless
fuel. The other is flat with a number of round holes (See
Fig. 6A). This is for wood burning only
.
THE WOOD GRATE MUST ONLY BE USED TO BURN
WOOD FUEL OTHERWISE DAMAGE MAY OCCUR TO
THE GRATE AND THE APPLIANCE.
The grate with the serrated edge may be used to burn
either fuel, but the fuel consumption may be higher on
wood and so refuelling intervals will be increased and a
bed of ash will not build up. This ash is necessary for
wood burning. Although possible, it is not really
practicable to change the grate when the cooker is alight.
These parts get very hot during operation and there is a
risk of serious injury. Removing the grate will result in any
burning fuel falling out of the cooker so this operation
should be carried out when the appliance is not alight.
To fit the wood grate, open the fire door and insert the
grate through the door opening with the four legs facing
downwards and the flat edges of the grate facing left and
right. (See Fig. 6A).
Secondary Air Adjustment - Rayburn 212SFW Only
When converting from solid fuel to wood burning, the
secondary air calibration will require changing from a 6
aeration hole plate to a 8 hole plate, (See Fig. 6B). This is
done by simply unscrewing the chrome caps and
removing two screws.
