Fitting baffles (continuation)
Positioning of the lower chicane
in the double-sided models
Fit side supports [diagram 15 A] ; the
short 4 cm lugs [photo 16 A] should
be turned towards the inside of the
hearth.
Tips of side supports lodge into
grooves [photo 17].
Make sure that these supports run
perfectly parallel to the side refractor
plates.
Check that the tips of support are well
lodged in the grooves and that they
are not stuck between the tip of the
groove and the hearth wall.
Fit the "front" crosspieces
[photo 15 B] into the hearth's
outermost notch.
Position the central crosspiece
[diagram 15 C] : it is made up of two
pieces positioned back to back. Lodge
the lugs into the central notches (dip
of V) of side uprights.
Fit the 4 vermiculate plates : first rest
towards the outside of the hearth on
the front crosspiece then rest on the
central crosspiece [photo 18].
Adjusting the baffle according to
draught
If the draught is inadequate, move the
front crosspiece towards the centre
of the hearth. Insert the lugs into the
corresponding notches [photo 19].
Run this operation in a symmetrical
way on both faces of the hearth.
Secure and centre the elements
[photo 20].
