Attaching Air Restrictors – Appliances with Vertical Vent Rise
Only
No restrictors are required for appliances, which only have a horizontal vent, run.
There are three types of restrictor supplied with each #530 engine unit. They are slightly
different in size. They can be identified by the number of indents – Type 1 has 1 indent, type
2 has 2 indents etc. – See figure 47.
The restrictors cover part of the openings in the firebox rear wall ports – See figure 48.
Each restrictor can be fitted at either Maximum or minimum port opening – See figure 48.
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 fitted for each type of installation are shown in the table below.
To fit the restrictors, remove the center screws from the rear ports and fit 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.
Figure 47
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.
