Where Sirius is being used with ICID Plus rather than Permeter Smooth Air , and the air feed kit is being used to provide a direct air feed into the rear of the Sirius appliance. The correct spigot configuration must be used (see p. 16 of the Sirius Operating Manual).

Once the cover for the air feed and the spigot have been attached, then the insulated adaptor from Sirius to ICID provides a basic single wall to double wall adaptor, which connects into the spigot. An inspection pipe with a test point should be used immediately above the Insulated adapter to provide cleaning access for the stove and a test point for draft testing.
