The primary purpose of clearance around gas appliances is to ensure safety from heat and fire hazards. Adequate clearance allows for proper ventilation, which is essential to prevent the buildup of flammable gases and to allow for safe operation of the appliance. Additionally, it minimizes the risk of overheating adjacent structures or materials, which could lead to fire. Having the necessary space around gas appliances also assists in the dissipation of any heat generated during their operation, further reducing safety risks.

While easy access during repairs, aesthetic appearance, and improving system efficiency are important considerations in the installation and maintenance of gas appliances, they do not hold primary importance compared to the critical aspect of safety. Maintaining the right clearance is essential to comply with safety codes and regulations, ultimately protecting both the occupants and the property.
