Venting
Attaching Air Restrictors
Appliances with more than 10'-0" Vertical
Vent Rise Only
No restrictors are required for appliances which that have
less than 10'-0" vertical run. If installing an appliance which
has less than 10'-0" vertical vent pipe rise, ignore this stage.
Two restrictor sets, like the one shown right, are
supplied with each 530 engine unit. The restrictors
cover part of the inlet air openings in the firebox rear
wall on each side of the brick support. Do NOT install
the restrictors in the roof of the firebox!
Each set is assembled with an adjustable piece which
can be moved to different positions depending of the
vent configuration. See the table below to find out
which position is optimal for each type of installation.
• To fi t the restrictors, loosen the two center screws of
the left and right inlet ports. Place the restrictor as-
sembly under the screw heads and tighten the center
screws.
• To set the adjustable restrictor piece, loosen the two
screws, position the adjustable piece according to the
diagram below and tighten the screws.
