  • Consumer Safety Reset CSR - Allowing the homeowner to quickly “reset and go” the gas installation, should the OPSO shut due to events such as accidental impact when changing cylinder , overwintering etc. which can be more of a nuisance than a hazard, but still protecting the consumer and property against potential excessive high pressure incidents. The new design ensures that the device cannot be tampered with or adjusted so continued intervention then clearly indicates that a qualified engineer is required to inspect the gas installation and reseal in the normal way.
