3.3 Pellet Storage
3.3.1 Pellet Hoppers and Pellet
Feed Auger
All Grant Spira boilers are supplied with
a pellet hopper. Refer to Section 1.4.4
for further details of the hoppers.
All Grant hoppers are supplied with
either one or, on a double boiler
hopper, two 1.2 m pellet feed augers,
to deliver the pellets from the hopper to
the boiler. Refer to Section 1.4.5.
The pellet hopper, along with the boiler
(or boilers) it is supplying, MUST be
installed in a dry indoor environment
free from dampness. The hopper and
boiler(s) must be located on the same
floor level. The hopper must be located
adjacent/between the boiler/s as shown
in Section 2.
If a bulk hopper is to be used, there are
two methods of transferring the pellets
from the bulk store to the intermediate
hopper:
a) Via a bulk pellet feed auger
b) Via the Grant SpiraVac vacuum
pellet feed system
All boiler pellet hoppers are supplied to
accept either of these two pellet supply
systems, as required. Refer to Section
1.4.4 for further details on the hoppers.
The electrical connections to the
boiler(s) are all made to the 4-way
electrical plug on one of the three
factory-fitted ‘flying leads’ at the rear of
the hopper.
Electrical connection for either a bulk
auger or Grant SpiraVac system, if
required, is made using the 6-way
electrical plug and flying lead supplied
factory-fitted on the hopper. Refer to
Section 8 for details.
3.3.2 Bulk Hopper
It is advisable to fit a bulk pellet store
to take advantage of the lower cost of
pellets purchased in bulk.
The pellet hopper (supplied with the
boiler/s) must still be used, situated
between the bulk hopper and the
boiler, as the auger fitted to the hopper
delivers the precise quantity of pellets
required by the burner.
The pellet hopper also allows any
problems with bulk pellet quality to be
isolated and the intermediate hopper
can be used temporarily as the source
of pellets for the boiler. It is essential to only use a bulk storage
unit that is:
a) Waterproof
b) Specifically designed to store wood
pellets
c) Supplied with appropriate
connections for pellet delivery,
which are within the drivers reach
d) Fitted with a vent connection (for
dust extraction) during filling
e) Permanently vented (if located
outside) or unvented (if installed
indoors)
f) Fitted with a rubber arrester mat
(or similar) to limit pellet damage
during filling
g) Is electrically earthed
A range of suitable bulk pellet stores
are available from Grant UK. These are
supplied either pre-assembled or flat
packed for on-site assembly. Refer to
assembly instructions supplied with
each kit. For details of capacities and
dimensions visit our website or contact
Grant UK.
The use of a self constructed wood
pellet storage facility should be pre-
approved by the fuel supplier before
any pellets are delivered and must meet
!
NOTE
Each bulk pellet supplier has clear
guidelines on the requirements
of a bulk storage hopper used
to store their pellets, together
with requirements on positioning,
access, and minimum deliveries.
The information given in this manual
is for guidance purposes only and
you should ALWAYS check with
the pellet supplier you wish to use
BEFORE installing a bulk storage
system.

NOTE
The boiler must be switched off
before the bulk pellet store is
re-filled. The boiler must only be
switched back on again after the
filling is completed.
