Additional accessories can be incorporated into every chimney or vent
design. Most accessories are required by manufacturer requirements, or to
meet local and national codes (see
PV Quality Seal).
Power Venters - for sidewall venting or when routing exceeds
code lengths or manufacturers requirements.
Laundry Power Venters - fans specifically designed and listed
for use with lint laden air. These are variable speed fans that can run
at fixed or automatically varied speed.

forced draft appliances when specified by manufacturer or when draft may
exceed manufacturer requirements.
Vent Hoods - side wall venting terminations.
Draft Inducers - for industrial applications when long
horizontal runs or use in slightly negative pressure facilities.
Residential Kitchen Exhaust Fans - variable speed fans
specifically designed for quietness and longevity. These fans can run at fixed speed or use a variable speed switch.
Gas Vent Dampers - improves appliance efficiency by not
allowing residual heat and conditioned air to escape during off
cycles.
Combustion Air Systems - provides adequate air for combustion
when appliances are in confined spaces.
Pipe Insulation - used for single wall AL29-4C applications
when flue extends through unheated spaces and reduced skin temperatures
are needed.
Zero-Clearance Fire-Wrap - used for single wall grease ducts,
insulation is field applied to obtain a zero-clearance chase assembly.
