A residential building inspector is reviewing plans for a new single-family dwelling. The plans indicate the installation of a permanently installed outdoor barbecue grill on a combustible deck. What is the minimum clearance required from the sides and rear of the grill to combustible materials?
- A12 inches
- B0 inches
- C18 inches
- D6 inches
Show answer & explanationAnswer & explanation
Correct answer: B. 0 inches
For permanently installed outdoor barbecue grills, the IRC (adopting provisions from NFPA 54/IFGC) typically requires specific clearances to combustible materials. However, if the grill is specifically listed and labeled for zero clearance to combustibles, no minimum clearance would be required. Without information on the listing, a general code would apply, but the question implies the minimum needed. The most common interpretation for listed appliances is zero clearance unless otherwise specified by the manufacturer. If not listed for zero clearance, a greater distance would be required.
Why the other options are wrong
- A. 12 inches is often a general clearance for heat-producing appliances, but not specifically for permanently installed outdoor grills listed for reduced clearances.
- C. 18 inches is a typical clearance for solid-fuel appliances or unlisted heat sources, which is excessive for a listed outdoor gas barbecue grill.
- D. 6 inches is a common clearance requirement for some appliances, but not for all grills, especially if they are listed for zero clearance.
Outdoor Grill Clearance (Combustibles)
The minimum safe distance between a permanently installed outdoor barbecue grill and adjacent combustible materials, determined by the grill's listing and labeling to prevent fire hazards.
- Prevents ignition of nearby materials.
- Depends on appliance listing/labeling.
- Ensures fire safety in outdoor cooking areas.
Memory trick: Grill's 'G' for 'Generally' 'Zero' if 'Listed'.
