The firebricks should be fitted in the following order:
a. Fit the two rear summer bricks by placing the rectangular brick with the rebate to the bottom in the channel
welded on boilerface above the rear flue outlet. Fit the 'L' shape rear summer brick by positioning on floor of
combustion chamber and touching brick already fitted (see diagram 5). Locate back brick retaining bracket in
groove in boiler to retain bricks in position at top. When located, slide both bricks to the right hand side.
b. Locate the side rear firebrick inside the bracket fitted on the base, then push it toward the rear to locate behind
the two rear firebricks.
c. Locate the bottom end of the boiler side front firebrick inside the bracket fitted on the base. Gently push the top
end against the boiler side and secure the top end with a REMOVABLE stainless steel bar. The bar should be
located in brackets welded to the boiler. These four bricks should be removed for the winter season by the service
engineer and stored in a safe place together with removable clip and bar.
After ensuring that the burner chamber is correctly fitted for the forthcoming season, refit the top baffle bricks.
(N.B. These two firebricks are always in place summer and winter). Fit them as far to the RIGHT as possible,
leaving a gap for flue gases on the left hand side only. Replace the hotplate ensuring it seals around it's edges.
