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 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.
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.
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.
Secondary Air Adjustment
When converting from solid fuel to woodburning, the
secondary air calibration will require changing from a 6
aeration hole plate to an 8 hole plate. See Fig. 6.
This is done by simply unscrewing the chrome caps and
removing two screws.
