Step 8Venting
The furnace shall be connected to a factory built chimney or vent
complying with a recognized standard, or a masonry or concrete
chimney lined with a lining material acceptable to the authority
having jurisdiction. Venting into an unlined masonry chimney or
concrete chimney is prohibited.
When an existing furnace is removed or replaced in a venting
system, the venting system may not be properly sized to vent the
attached appliances. An improperly sized Category I venting
system could cause the formation of condensate in the furnace and
vent, leakage of condensate and combustion products, and spillage
of combustion products into the living space, etc.
