This termination vent/combustion air kit is for horizontal or vertical venting of Thermo
Pride's condensing gas furnaces. This kit is designed for extreme cold conditions when
traditional combustion air intakes may frost over causing nuisance shut downs of the
furnace. In addition to cold weather applications, this kit may also be utilized in other
sidewall vent applications where a single hole through the foundation or basement wall
is desired.
The following parts are included in the termination kit.
