seal supplied with the fire. This will need to
be fitted to the outer rear edges of the side
and top flanges of the hotbox. Cut the foam
seal to the required length. Be careful not to
stretch the seal when measuring. Remove
the protective backing from the foam seal
and fit this to the rear of the top flange (See
figure 10).

restrictor will have to be removed. After removal
