Overview
This Standard is about testing, purging and relighting appliances that are fueled by liquified petroleum gas (LPG). Liquified petroleum gas(LPG) includes propane and butane. This involves testing systems for soundness and compliance, purging gas supply, checking ventilation and flue systems, carrying out pre-commissioning tests and checks and complying with regulations related to health and safety and gas safety.
Appliances can be situated in any type of residential property or leisure accommodation including:
- boats, yachts and other vessels
- leisure accommodation vehicles
- permanent dwellings
- residential park homes
This standard is for anyone responsible for testing, purging and relighting propane or butane appliances in residential property or leisure accomodation.
