Where is a fire stop support plate typically located in a dedicated vent system?

• A. At the furnace itself
• B. Where it passes through a ceiling
• C. In the attic
• D. Near the wall connection

Answer: (B)

The fire stop support plate is typically found where a vent system passes through a ceiling. This location is crucial for safety and compliance with building codes, as the fire stop plate serves to prevent the spread of fire and smoke from one space to another through the openings created for venting ducts. By sealing around the vent in the ceiling, the fire stop plate maintains the integrity of the fire-rated barrier that ceilings often represent, thereby reducing potential hazards associated with flammable gases or exhaust products that could travel upward through these openings. This positioning is especially important in maintaining the structure's fire resistance and overall safety in residential and commercial buildings.
