Attaching Air Restrictors—Appliances with Vertical Vent Rise Only

•

No restrictors are required for appliances which only have a horizontal vent run.

•

Restrictors for co-linear applications are the same as required for co-axial of same

height—see table below.

•

There are three types of restrictors supplied with each #530 engine unit. They are

slightly different in size. They can be identiﬁ ed by the number printed on them.

The restrictors cover part of the openings in the ﬁ rebox rear wall ports.

Each restrictor can be ﬁ tted at either Maximum or Minimum port opening.

Types 1, 2 and 3 are supplied with ceramic log appliances.

Types 4, 5, and 6 are supplied with ceramic coal appliances.

The correct restrictors to be ﬁ tted for each type of installation are shown in the table

below.

•

To ﬁ t the restrictors, remove the center screws from the rear ports and ﬁ t the

restrictors using these screws.

•

To set the restrictors at maximum port opening, slacken the bottom screws in the

ports, slide the restrictors down as far as possible and tighten the screws over the

restrictors.

•

To set the restrictors at minimum port opening, slide the restrictors up as far as

possible and tighten the screws.

•

With the largest restrictors, the upper screws may need to be slackened to allow

the restrictors to go under the screw heads.
