The recommended protection for gas-fired equipment requiring an 18-inch clearance wall is 1/2-inch non-combustible insulation board. This type of insulation effectively reduces the heat transfer from the equipment, ensuring safety by preventing any potential ignition of nearby combustible materials. The use of non-combustible materials around gas-fired equipment aligns with safety regulations designed to minimize fire hazards, particularly in situations where the equipment is in proximity to walls or other structures.

Non-combustible insulation boards are specifically designed for high-temperature applications, offering excellent thermal resistance while complying with building codes. This makes them suitable for protecting the wall in applications involving gas-fired appliances, ensuring that the clearance requirement is met without compromising safety or efficiency.

Other types of insulation may not provide adequate fire resistance or thermal protection, which is essential for maintaining safe operating conditions in environments where gas-fired equipment is present. The choice of material directly impacts not just compliance with building standards, but the overall safety of the installation.
