The Office of the Fire Commissioner (OFC) has issued a bulletin on their Gas Burning Equipment – Field Approval program, which is designed to approve custom-made, one-of-a-kind, built-on-site, or limited-edition gas burning appliances that cannot be certified by designated certification organizations-
The field approval program covers the fuel features of appliances or equipment, like the gas supply and valves, the appliance and its venting systems. The program does not include approval of any electrical features of the appliances, equipment or components. The program is not intended to circumvent the normal procedure for certification of appliances, equipment and components by designated testing organizations.
Field Approval can be obtained two ways: through the OFC in accordance with CSA B.149.3; or by a third-party agency approved to perform CSA B.149.3 field inspections. Approval is valid only for the original intended use of the appliance or equipment, any alteration to the use or the equipment will require a new approval under the program.
The full version of the OFC bulletin can be found on The Grid.
