What is the minimum requirement for listed gas-fired toilets to be installed on combustible floors?

For gas-fired toilets to be installed on combustible floors, the minimum requirement is that they must be listed for such installation. This means that the appliance has been tested and approved by a recognized testing agency for safe use in that specific application, which includes compliance with safety standards applicable to combustible surfaces.

Ensuring that a gas-fired toilet is listed for installation on combustible floors is critical because it addresses the inherent risks associated with using gas appliances in close proximity to flammable materials. The listing provides assurance that the appliance has undergone evaluation for factors such as temperature control and safe venting of combustion gases, which is vital for preventing any potential fire hazards.

While proper venting, certified installation, and a dedicated gas line are important considerations when installing gas appliances, they do not supersede the requirement for the appliance itself to be listed for use on combustible surfaces. This listing is a fundamental safeguard that helps ensure both safety and compliance with applicable codes and regulations.
