21/125

21/75 & 21/85 DF

For models 21/75, 21/85, and 21/95

single-sided:

- lining the bottom: place the rebated

refractories towards the back (to

receive the back refractories)

- place the side refractories as far for-

ward as possible (with the rebate

towards the front of the fireplace),

so as to be able to fit the refractories

lining the back,

- place the back ones as far to the

outside as possible, and then centre

them,

- finally, push the side refractories

towards the back (to hold in place

the refractories lining the back).

For model 21/125:

The same procedure applies to the

other single-sided models, but the 4

refractories without rebates go in the

centre of the rear wall.

For levels 2, 3, and 4, place the

respective locking pieces in front of

refractories nos. 16, 21, and 26.

For the double-sided models:

21/75 & 21/85 ds : centre all refractor

plates.

21/95 ds (fig.3') : fit refractors 1 & 5,

then 2, 3 & 4 and finish with sides.

21/125 ds (fig.3") : fit refractors 1, 2,

6 & 7, then 3, 4 & 5 and finish with

sides.
