What is the minimum distance a gas water heater or boiler must be from a 275-gal oil tank?

The minimum distance a gas water heater or boiler must be from a 275-gallon oil tank is 5 feet. This regulation is established to prevent potential fire hazards and ensure safety in environments where flammable materials, such as oil, are present. The 5-foot distance provides a buffer that allows for proper ventilation and reduces the risk of ignition from any potential flames or hot surfaces associated with the gas equipment.

Maintaining this distance is essential for compliance with safety codes and regulations, which are designed to protect property and lives by minimizing the likelihood of accidents related to gas-fired appliances and combustible materials. This requirement reflects an understanding of the physical properties of gases and fuels, as well as their flammability aspects.
