INSTALLATION
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.
The diagram shows all allowable combinations of vertical runs with horizontal terminations, using one 45º and one 90º (two 45
o
90
) for direct horizontal runs with horizontal termination use only one 45º elbow.
Note: Must use optional rigid pipe adapter (Part# 510-994) when using Rigid Pipe Venting Systems.
VENT RESTRICTOR SETTING:
Vent restrictor factory set, no adjustment required unless otherwise indicated.
Refer to the "Vent Restrictor Position" section for details on how to change the vent restrictor from the factory setting of Set 0 to Set 1 or Set 2 if required.
