Draught diverter
The R18 is fitted with a draught diverter. It is possible to con-
nect the flue outlet connection on the top cover with a standard
flue pipe. The inside of the draught diverter is insulated. The
mantle is easily removed without the use of any special tools by
means of a click system.
Combustion chamber
The chassis consists of two side frames with steel supports.
Dura blanket type thermal insulation is sandwiched between the
vermiculite refractory blocks and front, rear and side panels of
the combustion chamber housing. These vermiculite refractory
blocks are mounted so as to allow freedom of expansion. The
refractory blocks backed with the Dura blanket insulation form
the combustion chamber.
