12.2 FLUE RESTRICTION
The Installation notes in these Instructions, particularly those
regarding Maximum Flue Lengths and Configuration Options,
take precedence over any universal instructions included in
flue component packs.
To ensure the correct operation of the appliance, certain
flue lengths require one of two flue restrictor rings to be
fitted to the air inlet. (Fig. 12).
Restrictor requirements for the horizontal and vertical flue
configurations shown in Figures13 and 17 are as per tables
6 and 7 respectively.

12.2.1 Restrictor Ring Installation.
Unfasten the fixing screws (Fig. 12, pos. 1) securing the flue
support ring (Fig. 12, pos. 2).
Place the restrictor ring (Fig. 12, pos. 3) between the flue
support ring and the appliance sealed box, align the holes
and re secure.
12.3 FITTING A HORIZONTAL FLUE
Possible flue configurations are as per Fig 13.
The concentric horizontal flue system has an inner flue tube
diameter of 60 mm and an outer air duct diameter of 100
mm.
Standard horizontal flue terminal kits and flue extension
components are detailed in Section 3, Page 6, Table 2 -
Flue Details.
The Maximum and Minimum flue lengths available for
horizontal configurations are as per table 8.
