relevant building and fire regulations.
The ONORM M7137 standard should
be used as a guideline for DIY bulk
storage units.
A storage unit should not be positioned
where it would result in a fire risk.
The store should be located on a
suitable base (e.g. concrete) capable of
supporting the weight of the store when
full of pellets.
3.3.3 Bulk Pellet Feed Auger
When installing a bulk pellet store with
a bulk pellet feed auger, consideration
must be given to the position of the
store in relation to the hopper as this
will dictate the length of the auger.
The length of the pellet feed auger,
supplying pellets from the bulk store,
is limited to a maximum of 6 metres in
length, as a longer auger can damage
the pellets.
Grant UK offer a range of eight bulk
pellet augers, from 2.5m to 6m in length
in 0.5m steps, as given in the following
table:
To determine the length of auger
required the following factors must be
determined:
•
Difference in height between the
ground/floor level (on which the
store will stand) and the floor level
(on which the hopper will stand).
•
Horizontal distance between the
back of the hopper and the store.
If the store is to be situated outside,
this horizontal distance will be made up
from:
•
The distance from the rear of the
hopper to the inner face of the wall
•
The thickness of the wall
•
The distance to the store from the
outside face of the wall.
