The boiler should be serviced by a competent
person. The Gas Safety (Installation and Use)
Regulations require that only Registered (i.e.
CORGI Registered) gas personnel should install,
commission and service gas fired equipment such
as these boilers. Failure to comply with these
Regulations may lead to prosecution.
The boiler should be serviced at regular intervals,
not exceeding SIX months for oil fired boilers, or
TWELVE months for gas fired boilers.
When carrying out boiler servicing always consider
both your own safety and that of others. The use of
protective equipment (e.g. eye protection, face
mask, protective gloves, etc.) is recommended
where necessary.
