3. INSTALLATION
3.1. UNPACKING APPLIANCE
ATTENTION
Our appliance may require 2 people when lifting the boiler to the installation
site and throughout the installation process when lifting and positioning is
carried out.
Installers should be knowledgeable in safe handling techniques and pay
attention and follow all Health & Safety policies put in place by their
company.
Carefully unpack the boiler unit from it’s box and remove the unit from
the polystyrene packaging and dispose of the boiler packaging to comply
with your local waste management guidance.
3.2. APPLIANCE POSITION
ATTENTION
The surface where the boiler is to be mounted must be flat and rigid and be
able to withstand the appliance total installation weight.
Care should be taken on the appliance position and location to ensure the
correct standards are met for the following:
• Flue terminal position and access to flue joints.
• Condensate discharge.
• PRV discharge and termination.
A visual inspection should be carried out to ensure when positioning the
appliance any drilling of the mounting bracket or pipe clips will damage
any electric cables or pipes.
3.3. WALL MOUNTING TEMPLATE
Please ensure you mount the template level before drilling any holes and
ensure you are drilling the correct holes as per the template guidance.
The wall mounting template should be fixed to the desired position on the
surface where the boiler is to be installed, after fixing the template please
set the flue guide on the template to match your desired flue position.
Drilling of the fixing holes for the mounting bracket can also be done as per
the guidance on the wall mounting template.
The template also displays the
pipe centers and correct pipe
work layout for the correct
installation of the boiler pipe
work.
3.4. PREPARING THE WALL – DRILL FLUE HOLE
ATTENTION
When drilling the flue hole ensure that any falling masonry debris will not
cause an injury to person or damage to property, please make sure both
surfaces when drilled are flat and free of debris.
We recommend using a 125 mm core drill attachment to drill the flue hole,
this will give you some tolerance if required when positioning the flue.
3.5. INSTALLING MOUNTING BRACKET
INFORMATION
We suggest when drilling the holes for the mounting brackets you drill
holes that can accommodate 7.5 mm / 8 mm plastic raw plugs and that the
minimum fixing screws are No 10 x 50mm and ensure when the mounting
bracket is fixed it is level.
Ensure you make a minimum of 2 fixing points to be drilled to ensure
correct fixing of our mounting bracket.
Please ensure the mounting bracket is fixed in the correct orientation with
the two hanging points facing in an upwards direction.

3.6. HANGING THE BOILER
INFORMATION
Ensure that all the plastic safety plugs are removed from the CH and DHW
(for combi boilers only) inlet and outlet connections at the bottom of the
boiler.
Note that the boiler may contain some residual water when the plugs are
removed so care should be taken for this.
Taking all lifting techniques into consideration lift the boiler and locate it
over the two fixing tabs at either side of the mounting bracket.
Make sure the boiler is correctly
located on the mounting bracket
and that the boiler is level and
straight.
