INSTALLATION
VENTING INTRODUCTION
The HZ42 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
fl ue 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.
