6. If burning solid fuel with 1in B.S.P., or 28mm copper
flow and return pipes less than 7m each in length a
towel rail/radiator with a surface area of up to 1m
2
should be fitted and suitably valved to close off the
circulation in the event of a change to wood burning.
Domestic Hot Water and Heating (solid fuel)
When fitted for domestic hot water and heating burning
solid fuel the cooker will, with a burning rate to maintain
an oven temperature of 205-220°C (400-430°F), also
heat 9.3m
2
of radiator surface and pipes.
The recommended heating surface area is based on an
average heat emission of 0.5kW/m (160Btu/f h). The flow
and return pipes from the cooker should be connected to
a 190 litres
indirect cylinder
and the flow should be
vented.
Domestic Hot Water and Heating (wood)
When fitted for domestic hot water and heating burning
wood the cooker will also heat 5m
2
radiator surface and
pipes, but increased burning rate of the fuel must be
obtained to achieve this.
The recommended heating surface area is based on an
average heat emission of 0.5kW/m
2
. The flow and return
pipes from the cooker should be connected to a 190 litre
indirect cylinder
and the flow be vented.
PREPARATION OF SITE
The non-combustible hearth must be solid and level and
together with the walls adjacent to the cooker and
