5. Grate
The grate simply lays into the grate support but care
needs to be taken that the riddling bar will rest in the
middle of the fork.
6 & 7. Side & Back Bricks
Lay the side and back bricks in as shown in Fig.8.
8. Fire Fence
Lay the fire fence into the slots provided ensuring
that they slope from front to back so that no embers
can fall out through the fire fence.

DOWN DRAUGHTS
However well designed constructed and positioned,
the satisfactory performance of the flue can be
adversely affected by down draught caused by near-
by hills, adjacent tall buildings or trees. These can
deflect wind to blow directly down the flue or create
a zone of low pressure over the terminal.
A suitable terminal or cowl will usually effectively
combat direct down blow but no cowl is likely to pre-
vent down draught due to a low pressure zone.
(See Fig.9).

of the frame over the top hinge point for the door and
engaging the cut-outs on the back of the frame into

Four Sided Frame
Fit the four sided frame by inserting the frame over
the firedoor and air controls and engaging the cut-

the shell. Secure in position using the two fixing
screws as shown in figure 8b.
