Consult the table on Page 18, to see if a restrictor
is required for the type of flue system being used.
Should it be necessary to fit the restrictor, it must
be fitted as illustrated in Fig. 20.

Where it is not possible to terminate the flue within the dis-
tance permitted for coaxial flues, the twin flue pipe can be
used by fitting a special adaptor to the flue connector and
using the aperture for the air intake located on top of the
combustion chamber.
Always ensure that the flue is adequately supported, avoid-
ing low points. (MTS supply suitable clamps as Part No.
3318015).
To utilise the air intake it is necessary to:
1) Take the air intake cover off
2) Assemble the flange on the header supplied with the
appliance
3) Insert the restrictor if necessary, between the tube and
the elbow
4) Insert the header on the tube or the elbow up until the
lower stop (you do not have to use a washer).
5) Insert the elbow/header in the boiler air intake hole and
fasten it with screws.
The twin flue pipes can be fitted with or without additional
elbows and need no clamps, simply ensure that the red o-
ring is inserted in the female end of the flue pipe and push
the extension piece fully into the previous section of flue pipe
or elbow, check that the o-ring is not dislodged when assem-
bling the flue.
Twin pipe can also be converted back to Coaxial flue to
enable vertical termination with a coaxial kit by using the
pipe bridge (Twin - Coaxial Adaptor - Part No. 3318033).
When running the twin flue pipe vertically.
