(See Para. re: Firebrick Positions
The maximum boiler output obtainable burning solid fuel at the
optimum burning rate - with the cooker/boiler damper knob at
H
and the boiler thermostat at No.8 - is 16.12kW (55,000 Btu/h).
This will provide for 29.89m of radiator surface and pipework
plus domestic hot water or 32.24m of radiator surface and
pipework only. The recommended heating surfaces indicated
are based on an average heat emission of 0.5kW/m (160
Btu/h/ft). When cooking only, with the cooker/boiler damper
knob at
C
and oven at a steady 230ÞC (450ÞF), the water
output reduces to 5.6kW (19,000 Btu/h). Overnight banking with
the cooker/boiler damper knob at
C
will produce 2.3kW (8,000
Btu/h) of hot water from the boiler.
Summer Use
See para re: Firebrick Positions
With the cooker/boiler damper knob at
C
and the oven
temperature maintained at a steady 200ÞC (390ÞF) the hot
water output from the boiler will be 3.1kW (10,500 Btu/h).
Overnight banking with the cooker/boiler damper knob at
C
will
produce 1.9kW (6,900 Btu/h) of hot water from the boiler.
Winter Use:
To obtain the optimum burning rate with the wood
burning fuels only, a grate baffle should be located on the top
face of the reciprocating bars, at the rear of the firebox.
See diagram.
Grate riddling is not required when burning wood where poking
will normally suffice.
Always remove this grate baffle when burning solid fuels.
See para. re: Firebrick Positions
The maximum boiler output obtainable burning wood logs at the
optimum burning rate - with the cooker/boiler damper knob at
H
and the boiler thermostat at No.8 - is 10.26kW (35,000 Btu/h).
This will provide for 18.17m
2
(194ft
2
) of radiator surface and
pipework plus domestic hot water 20.52m
2
(219ft
2
) of radiator
surface and pipework only. Overnight banking with the
cooker/boiler damper knob at
C
will produce 1.46kW (5,000
Btu/h) of hot water from the boiler.
Summer Use
See para. re: Firebrick Positions
With the cooker/boiler damper knob at
C
and the oven
maintained at roasting temperature the hot water output from
the boiler will be 2.6kW (9,000 Btu/h) of hot water from the
boiler.
Overnight banking with the cooker/boiler damper knob at
C
will
produce 1.46kW (5,000 Btu/h) of hot water from the boiler.
The non-combustible hearth must be solid and level and
together with the walls adjacent to the cooker and chimney,
conform to current Building Regulations.
The cooker and chimney flue installation should be in
accordance with the relevant recommendations of the British
Codes of Practice BS 8303, BS 6461 Part 1 and BS 7566 Parts
1 to 4 respectively and the central heating system to BS 5449
Part 1. The boiler installation section must also be in
accordance with the byelaws of the local Water Undertaking,
Regulations for the Electrical Equipment of Buildings -
published by the Institute of Electrical Engineers and any
relevant requirements of the Local Authority.
Ensure that any electrical wiring is correctly earthed.
When the cooker is installed in a recess it must be
‘freestanding’ and not built-in solid at the sides. Ensure that any
combustible material e.g. kitchen furniture is spaced away from
the cooker to the recommended distances. See Fig. 1.
Tiling
Where the cooker is to stand in a recess or against a wall which
is to be tiled,
in no circumstances should the tiles overlap
the cooker top plate
.
From 200mm thick non-combustible or new recesses, an
opening of 1,080mm wide minimum, by 343mm deep minimum
and 1,680mm high minimum from floor is recommended.
NOTE (SEE FIG. 1): PLEASE NOTE IT IS ADVISABLE TO
CHECK THE SIZE/WIDTH OF YOUR APPLIANCE BEFORE
FINALLY FIXING ANY KITCHEN UNITS SINCE ENAMELLED
CAST IRON CAN VARY IN SIZE.
