local authorities and bodies. If no specific requirements are defined, in
the USA, the latest edition of the National Fuel Gas Code ANSI Z223.1/
NFPA 54 applies. In Canada, installation must comply in all respects with
the latest edition of the Installation Code for Gas Burning Appliances and
Equipment, CAN/CSA-B.149 and the applicable local regulations and
requirements for the appliance category. The relevant authorities and
regulatory bodies must be informed before installation starts.
Where required by local regulations, the system must comply with the
American Society of Mechanical Engineers Safety Code for Controls and
Safety Devices for Automatically Fired Boilers (ASME CSD-1).
