Fitting Baffles - Stuv 21 Installation Instructions Manual

Fitting baffles

Upper and lower baffles are designed
to regulate draught and to improve
performance.
Note
Depending on the draught, one
could first move the lower adjustable
baffle. Then influence the draught by
modifying the pre-cut upper baffle
(remembering that this modification is
irreversible).
Fitting upper baffle
The upper baffle is made of two
stainless steel sections. One fits to
the left and the other to the right
[photo 1and diagram 2].
These pieces are supplied pre-cut.
If the draught of the chimney is
insufficient, reduce the chicane by
"breaking" it symmetrically and
gradually along the pre-cut lines
[photo 3].
If the chimney does not provide a
good draught, do not insert the upper
chicane.
Place left-hand section first by running
hand through cut-out [photo 4]. (For
chimneys of at least six metres).
The upper lug of the baffle
[photo 1 A] should rest on the top
core of the deflector [diagram 2].
In the same way, place right-hand
section to overlap left-hand section.
Positioning of the lower chicane
in the single-sided models

Note that R/H and L/H supports are
different [photo 6] ; the short 4 cm lug
should be turned towards the inside of
the hearth [photos 6 & 7].
