Hangers and brackets supporting unit heaters shall be made of what material?

• A. Noncombustible material
• B. Supplied by the manufacturer
• C. Stainless steel or zinc-coated sheet metal
• D. ASTM A53-97b material

Answer: (A)

Supports for unit heaters must be made from noncombustible material. This requirement helps prevent ignition from heat or sparks and ensures the brackets and hangers won’t contribute fuel to a fire, especially since unit heaters operate at elevated temperatures. Using noncombustible materials keeps the installation safer under heat exposure and aligns with fire safety and building codes. The other options don’t fit because the code doesn’t specify a manufacturer-supplied component, a particular specific material like stainless steel or zinc-coated sheet metal, or a piping standard as the basis for hanger material.
