Vertical Venting Examples
Installation Instructions Cont.
Always maintain a 1” clearance around the vent pipe (vertical) and on horizontal venting 2” clearance on the top of
the vent, when passing through ceilings, walls, roofs, enclosures, attic rafters or any combustible surfaces.
DO NOT PACK AIR SPACES WITH INSULATION.
Refer to the vent chart on page 18 for maximum allowable vertical and horizontal allowable installations.
When planning your installation, determine if ceiling joists, roof rafters or other framing will obstruct the vent system.
You may have to use 45° elbows to navigate around any obstacles. When passing through a flat ceiling, install a
Box/Wall thimble. Cut a 10” square hole and frame as shown in the diagram opposite.
Ensure all pipe sections are fully twist locked.
NOTE: ALWAYS CHECK YOUR LOCAL
CODES BEFORE INSTALLING VENTING.
CLEARANCES, ETC, MAY VARY FROM

through the roof as supplied by the vent
manufacturer.

Vent Restrictors
Due to the extra flow produced by tall venting configurations the vent restrictors must be adjusted to
maintain performance. The vent restrictor is designed into the appliance firebox.
When required, adjust the restrictor inside the unit firebox. Release the screws and adjust the restrictor
position according to the venting charts.
Adjust restrictor as re-
quired using appropriate
hole position
