Save people and property from fire, smoke, and gases spreading through homes. Apply the latest edition of NFPA 90B.

Depend on NFPA 90B: Standard for the Installation of Warm Air Heating and Air-Conditioning Systems for vital fire protection assurance. Be sure you're up-to-code with the most up-to-date requirements to keep fire, smoke and gases from originating in and spreading through indoor HVAC systems in 1- and 2-family dwellings, and buildings that are under 25,000 cubic feet.

Compliance helps protect lives and property from hazards resulting from fire or conditions similar to fire.

NFPA 90B requirements cover construction, installation, operation, and maintenance of systems for warm air heating and air conditioning -- including filters, ducts, and related equipment. The 2018 edition includes reference updates and clarifications of existing language. Also, a new requirement for duct sealants has been added.

Provisions address:

• HVAC systems, components, and air distribution
• Integration of a ventilation and air-conditioning system(s) with building construction
• Controls including wiring, manual control, smoke dampers, and smoke detection for automatic control
• Acceptance testing

AHJs, architects, contractors, mechanical and fire protection engineers, and building owners need NFPA 90B.
