A vertical connector can be supplied for vertical
discharge with concentric pipes.
The simple mounting and use of double lip gaskets
at the joints makes this an extremely easy and safe
option.
For flue length up to 1 m long the 50 mmØ restrictor is
required. Longer than this no restrictor is required.
