P90 Zero Clearance Direct Vent Gas Fireplace

INSTALLATION
VENTING
INTRODUCTION
The P90 uses the "balanced fl ue" technology
Co-axial system. The inner liner vents 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.
Note: These flue pipes must not be
connected to any other appliance.
The gas appliance and vent system must be
vented directly to the outside of the building,
and never be attached to a chimney serving a
separate solid fuel or gas burning appliance.
Each direct vent gas appliance must use it's own
separate vent system. Common vent systems
are prohibited.

There are 2 plates, one on the top and bottom
that can be folded out as required.
