Ductwork Requirements

Install all conditioned air plenums, ducts and air filters in
accordance with NFPA 90B Standard for the Installation of
Warm Air Heating and Air-Conditioning Systems (latest
edition).
The furnace is provided with flanges for the connection of the
plenum and ducts.
All air filters must be listed as Class 2 air filters.
All ductwork must be made of materials and insulated to
meet local, state and national codes. Ductwork installed

of adequately providing a permanent weather seal should be
used where duct penetrates a building or structure opening.
