Firebrick Positions and Replacement
The Rayburn is delivered complete including a set of
boiler removable firebricks where positional location
determines the amount of hot water supplied in winter and
summer seasons. The oven side and firebox firebricks are
permanently fixed with fire cement whilst the two boiler
side bricks are located for the summer season thereby
providing domestic hot water only.
For winter use or central heating facilities, the boiler face
side bricks are removed. See Figs. 3, 4 and 5.
The firebricks fitted to Rayburn Cookers are of first quality
manufacture, and providing the cooker has been installed
and used correctly will have a reasonable life.
They are however, expendable items and in time will
require renewal. The renewal of firebricks is not a major
operation and can be carried out by the average
handyman. The boiler side firebricks are supported on a
frame on the boilers sides and are held in position by a
retaining toggle at the top.
The front plate protection firebrick is held in position by a
retaining rib on the boiler side. The firebricks are not
attached with fire cement and can be removed and refitted
quite simply. See Fig. 5.
Replacement bricks either in sets or singly can be
obtained from your Rayburn stockist. Quote the serial
number which will be found on a data plate fixed to the
appliance. Do not force out the firebricks, they may
become brittle after firing.

Fuelling with Wood or Peat
The cooker will satisfactorily burn wood logs, blocks or
peat briquettes, but the logs should be perfectly dry in
order to obtain the best cooker performance and minimise
the deposits of creosote. Wood logs may also provide
overnight banking and the following hints are
recommended:-
