It is the law that all gas appliances must be installed by a

competent person in accordance with the above regulations. Failure to

install appliances correctly could lead to prosecution. It is in your

interest and that of safety to ensure compliance with the law. The

read these instructions carefully. 

In the event of a fault the appliance should not be used until the

BENCHMARK

The Benchmark 

initiative is 

the new 

code of 

practice to

encourage the 

correct installation, 

commissioning 

and 

servicing 

of

domestic central heating boilers and system equipment.

The ‘log-book’ 

is a 

vital document 

that must 

be completed 

by the 

installer

at the 

time of 

installation and 

handed to 

the householder. 

It confirms 

that

the boiler 

has been 

installed and 

commissioned according 

to the

manufacturers instructions.

Without the 

completion of 

the log-book, 

manufacturers may 

refuse to

respond to 

a call-out 

from a 

householder, who 

will be 

advised that 

he or

she must 

call 

back the 

installer, who 

has 

not fulfilled 

his obligations 

to

record the information required by the initiative.

It is important that:

The services and the system are properly flushed as specified.

The user is clearly instructed on the correct operation of the appliance.

The benefits 

of regular 

servicing are 

explained – 

to maintain 

the efficiency

and extend the life of the appliance.
