PB-1525 Wood Pellet Burner System: Installation and Operation Manual
Rev 1.0, OCTOBER 2011
Page 15 of 67
1525 pellet feed tube without the use of the supplied
flexible plastic drop tube assembly. This tube acts as a
back-burn safety device and is the only material suitable
for use. Replacing this tube with any other than supplied
by Pellergy voids the warranty and can result in injury,
equipment damage, and even death.
Do not install the conveyor drop tube directly over the PB-
1525 pellet feed tube. Misalignment is intended and acts
as a safety feature.
NOTE
The feed conveyor must not exceed 10 FT in length. Adding to
the length of the feed conveyor will result in burner malfunction.
2.
When positioning the pellet hopper and installing the conveyor into
the pellet hopper:
a.
The conveyor must be installed at an angle between 40-50º
as shown in Figure 2.3 above.
b.
The feed conveyor auger tube must not exceed 10 FT in
length. The feed conveyor may be cut to a desired length
provided that final length is able to meet all other installation
requirements of the conveyor.
3.
Install the overhead anchor and hang the conveyor using an
appropriate chain, cable or anchor as in Figure 2.3 above.
4.
Install the conveyor into the pellet hopper, ensure there is
clearance between the auger spiral and the bottom of the hopper
of at least 1-inch. If the conveyor auger makes contact with the
bottom of the hopper, damage can occur. Refer to Figure 2.4
below.
The auger spiral end should ride on the auger tube ring created by
the cutout on the end of the auger tube. If the auger spiral is cut
too short it may “hop” out of the auger opening and jam. If the
auger spiral is cut too long it may wear through the bottom of the
hopper bottom causing damage to the system and jamming the
auger system.
