Acceptance for steam boilers
By David Harrison,
ESV Investigations Officer
There’s a process that needs to be
followed to get Type B appliances (steam
boilers included) accepted. So if you are
contemplating the installation of a steam
boiler at your premises you must follow the
requirements of the Gas Safety Act and
Gas Safety Regulations.
Steam boilers using natural gas or LP Gas
as a heat energy source fall under the provisions
of the Gas Safety Act 1997 and require an
application for acceptance, including the additional
information to be supplied for a Type B appliance
(as detailed in Schedule 9 of the Gas Safety
(Gas Installation) Regulations 2008) to be
submitted to ESV.

Schedule 9 requires you to provide the
following information:
»» Appliance details
»» Description of the appliance function
»» Valve train schematic diagram

»» Process and instrumentation diagram
»» Purge time calculation
»» Safe start gas rate
»» Explosion relief area and dilution air flow rate
»» Details of flueing
»» Details of ventilation
»» Commissioning procedures and
operating instructions.
In the case of a Type B appliance with a
nominal gas consumption of more than 1000MJ
per hour, the gross thermal efficiency over its
designed operating range and a statement
comparing the appliance’s efficiency with the best
available performance in its class are required.
For an explanation of the Type B application
