BOILER ERECTION

A lifetime guarantee is available on this boiler when
erection and commissioning is carried out by the
Potterton Commercial service department and the
system meets with our recommendations. Please
refer to our standard terms and conditions for further
details.
Risk Assessment
Before starting work a risk assessment should be
carried out on the boiler house and its access to
determine and ensure a safe installation and working
environment.
Regardless of the type of activity being assessed, the
principles of risk assessments are the same. The
basic steps are: -
•
Classify Activity
•
Identify Hazards
•
Identify Existing Control Measures
•
Determine Risk
•
Assess Acceptability of Risk
•
Prepare a Control Plan
•
Implement Plan
•
Review Plan
•
Record Results
Manual Handling
Any person or persons moving or lifting the boiler or
any part of the boiler, should be trained in manual
handling techniques and if necessary use suitable
lifting equipment to reduce the risk of injury to
themselves and other people.
Personal Protective Equipment
When undertaking any work you must comply with the
Personal Protective Equipment Regulations 1992.
Confined Spaces
A "confined space" as defined in the Health & Safety
Confined Spaces Regulations 1997
place, including any chamber, tank, vat, silo, pit,
trench, pipe, sewer, flue, well or other similar space in
which, by virtue of its enclosed nature, there arises a
reasonably foreseeable specified risk'.
Precautions should be taken in all areas where by
virtue of its even partially enclosed nature, pose a
reasonably foreseeable specified risk.
Electrical Safety
Working on appliances can be broken down into two
main systems of work.

In the case of (1) above, electrical work should only
be undertaken once the boiler has been isolated from
the electricity supply and confirmed electrically dead.
If this is impractical then suitable precautions must be
undertaken to prevent injury.
In the case of (2) above, checks are specified to
identify any abnormality in the electricity supply to the
boiler, as well as to confirm that the boiler electrical
connections are reinstated correctly where it is
necessary to disconnect or reconnect any internal
wiring within the boiler.
If it is necessary to disconnect and reconnect the
appliance from the site electrical installation other than
by means of a plug and socket then additional checks
shall be undertaken by an approved engineer to check
the earth loop impedance with IEE regulations.
Always carry out preliminary electrical safety checks.
All appliances and central heating systems must be
provided with their own means of isolation for safety
purposes
maintenance.
Preparation
Preparatory to installation of the boiler a check must
be made to ensure that suitable facilities are available
for off-loading of the individual waterway sections and
conveying them to the boiler room. Each waterway
section weighs approximately 142 kg and measures
220mm x 860mm x 150mm. Ensure all manual
means 'any
handling techniques are followed.
Particular attention must be paid to ensuring the
cleanliness of the boiler room and waterway sections,
dust or moisture may result in imperfect adhesion of
the sealants which are applied during the erection of
the waterways. All tapped holes should be degreased
before making connections.
Safe systems of work are adapted for all boiler
maintenance and repair work undertaken on site.
The work undertaken does not effect the electrical
safety of the appliance. In particular the earth
