Masport Piccolo Installation Instructions Manual page 9

FLUEING INTRODUCTION
The Masport uses the "balanced flue" technology Co Axial system. The inner liner flues products of combustion
to the outside while the outer liner draws outside combustion air into the combustion chamber thereby eliminating the
need to use heated room air for combustion and losing warm room air up the chimney.
There are 2 flue systems approved for use with the Roma: the Masport Direct Vent System (Flex) for Horizontal
Terminations only, and the Masport System for Vertical Terminations.
Note: These flue pipes must not be connected to any other appliance.
The gas appliance and flue system must be flued directly to the outside of the building, and never be attached to a
chimney serving a separate solid fuel or gas burning appliance. Each room sealed gas appliance must use it's own
separate flue system. Common flue systems are prohibited.
