Important handling instructions
• It is advised that two people are used to carry the carton from the
vehicle to the point of delivery.
• Once the carton is in the property, the outer carton must be opened
whilst taking care not to damage the front cover. Sharp implements
should not be used to open the carton.
• Care should be taken when lifting the appliance from the base and the
proper technique for safe lifting of any heavy object should be strictly
observed.
• Cover the flue opening to guard against any debris entering the boiler.
Removing the front casing
The front casing is secured with two screws which are critical to maintain
the case seal and to prevent unauthorised removal (electrical safety).
▶ Always secure the casing with these screws.
Removing the front cover prior to hanging the boiler is recommended in
order to protect the front from scratches and damage.
▶ Loosen the two screws [1].
▶ Pull the bottom of the casing forward.
▶ Lift off the casing.

Roof space installation clearances
Important!
▶ In order to ensure personal safety when products are installed in roof
spaces, the following criteria should be achieved. Failure to make
proper provision for safe access to and maintenance of the product
may affect the warranty.
Access:
• A permanently fixed, retractable loft ladder is required for safe
access into the roof space.
– The ladder must be installed to comply with the manufacturers
instructions and the fixings used must be capable of safely
supporting the full maximum load capacity of the ladder.
– Step ladders, unsecured or temporarily secured ladders are not
considered to provide safe access.
• Fixed lighting must be provided to ensure safe access to and at the
working area.
Working area:
• The access route and working area must not be used as a storage
space and must be kept completely clear.
– It is not acceptable for anything that could result in an engineer
slipping or tripping or that will obstruct his access to be stored in
the access or working area.
– If the working area does not extend to the loft hatch, any boards
which are provided for access must be securely fixed to the ceiling
joists. The access boarding must be at least 600mm wide. Joints
must be properly supported and must not be overlapped.
• There must be provision for means of preventing accidentally
stepping into the loft hatch.
– Safety guard, handrail or safety chain to prevent accidentally
stepping into the loft hatch.
The same work area and access requirements would be required for any
floor standing equipment such as a cylinder.
