10.11 Customer Handover
The customer/user must be informed
of the correct operation and use of
their Grant Spira wood pellet boiler
installation. This must include the
following information:
• The use of the boiler controls –
how to switch the boiler off and
on, as required. Refer customer to
the User Instructions supplied with
the boiler/s. The use of the heating
system controls – how to set the
programmer, room and cylinder
thermostats, etc.
• The importance of using the
correct type of wood pellet.
• The need to routinely check the
pellet level in the pellet hopper
and how to re-fill it (hopper only
installations)
• The need to routinely check the
pellet level in the bulk pellet store
(bulk pellet store installations only).
The customer must also be made
aware that is can take several days
or longer, depending on the time
of year, before the store can be
re-filled.
• How to turn the boiler off and back
on (bulk pellet store installations
only) prior/after a bulk delivery.
• How to access the ash pan and
the need to periodically empty the
ash pan. Refer to Section 1.5 and
the User instructions.
• The need to have the boiler
serviced either annually or when
‘SERVICE’ is shown on the burner
control panel display (whichever
comes first). Refer to Section 1.5
and User Instructions.
• That servicing should only be
carried out by a Grant trained
installer.
10.12 Commissioning Report
Form
The Commissioning Report form
(supplied with the boiler) must
be completed at the end of the
commissioning process. Refer to
Section 4.15.
For a double boiler installation,
a commissioning form must be
completed for each of the two boilers.
The following information must be
entered on the form:
• Boiler details (model, serial
number, etc.)
• Combustion readings
• Installation details
• Burner settings
• Customer handover details
The completed form must be signed by
both installer and customer/user.
A copy of the completed form must be

• To increase the %CO
2
– decrease
the fan speed using button 5.
• To confirm the change in the
‘POWER MAXIMUM’ fan setting,
press button 4 twice, to exit the
‘SETUP FAN’ and ‘INSTAL’ menus
and return to the normal control
panel display (showing H2o and
SET temperature).
• Monitor the %CO
2
for a few
minutes to see if the maximum and
minimum values are 12% and 10%
as required.
• If necessary make a further
adjustment of the fan speed and
check the resulting %CO
2
as
described above, until it remains
within the required maximum and
minimum limits.
• Record the maximum and
minimum CO
2
values on the
Commissioning Report form. Refer
to Section 10.12.
On double boiler installations, the above
process – as covered in Sections 10.3

NOTE
It is essential to continue to monitor
the combustion chamber draught,
whist adjusting the CO
2
in the flue
gases, and to adjust the draught
stabiliser to keep it within the
required limits. Refer to Section
10.9.
