Attaching Air Restrictors—Appliances with Vertical Vent Rise Only
No restrictors are required for appliances which only have a horizontal vent run.
If installing an appliance which has a rear vent outlet connection and no 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 fi rebox rear wall behind the
rear log support.
Each set is assembled with an adjustable piece which can be moved to different
positions depending of the vent confi guration. See the table below to fi nd 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 assembly 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.
