5. Required Tools and Critical Tool Characteristics
Equipping the field crew with the right tools is essential for a smooth installation. The GSI Modular
Tower Dryer requires a number of standard tools. Please pay particular attention to the following item
descriptions as the characteristics of the following tools are extremely important information for proper
installation. A comprehensive list of tools required to assemble and install the GSI Modular Tower Dryer
is included later in this chapter.
Critical Tool Characteristics
1. 1-1/8" Hammer drill star bit at least 12" long is REQUIRED. While the anchor bolts are 1" in
diameter, the holes for the anchor bolts MUST be 1-1/8" in diameter to allow room for the required
epoxy. Additionally, anchor bolts must be sunk deep enough so that no more than 2"-3" is above
the plate.
An air compressor hose is needed to blow out the dust from the holes prior to dropping in the anchor
bolts and epoxy. (See Figure 5A.)
2. Air compressor with hose: After drilled the holes for the anchor bolts, an air compressor with hose
is REQUIRED in order to blow all dust and debris out of the holes.
Figure 5A Anchor Bolts Sunk - No More than 3" Remains above Plate
3. Punches: 1/4" Line up punches - at least 8
5/8" line up punches - at least 8
Ideally, during the installation process, crews will work in two (2) person teams with one team working
inside the dryer and one team working outside the dryer. Each crew member should have at least
two (2) punches available to them.
Punches should be long enough to provide significant leverage to the user and should have narrow
and pointed tips to facilitate the initial punch placement. (See Figure 5B andFigure 5C on Page 24.)

4. Socket sets and impact wrenches:
•3/8" Drive 1/2" socket set
•3/8" Drive 9/16" socket set
•1/2" Drive socket set
•15/16" Deep well 1/2" drive sockets
•1/2" Deep well 1/2" drive sockets
•Short 1/2" 1/2" drive sockets
•9/16" Deep well 1/2" drive sockets
•1/2" Impact wrenches
•3/8" Drive extensions (6" to 10") for 9/16" shallow socket
Accessing the bolts that connect sections of the dryer together requires passing through the hole in
the channel as shown in Figure 5D.
When installing, in all possible situations, place the impact on the bolt. Do NOT tighten the nut
as it will not lock down on the ring. Always tighten the bolt. (See Figure 5D.)
Figure 5D Connecting channels often requires the use
of socket extensions. Please plan accordingly.
PNEG-1708 GSI Modular Tower Dryer25
5. Required Tools and Critical Tool Characteristics
5. Laser transit level tool: After placing the unload/base module on the concrete foundation and
establishing its proper orientation to other equipment it must be leveled. GSI strongly recommends using a Laser transit leveling tool to level the unit.(See Figure 5E.) If a Laser transit is not
available, a carpenter’s level may be used.
It is critical to establish the base/unload module as level. Even a minor deviation at this level will be a significantly greater deviation at the top section. Therefore, pay particular attention to
confirming the levelness of the base/unload module. Shims are available to assist with leveling the
base/unload module. (See Figure 5F.)

5. Required Tools and Critical Tool Characteristics
Compression channel ledge
a. Compression channel: Regardless of what leveling tool is used, the prope r reference point f or
leveling the unload module of the dryer is the Compression Channel and NOT the base/leg
plates on the concrete. See Figure 5G for reference.
The Compression Channel is the “ledge” around the unload module of the dryer. Use this as the
reference point for leveling the unit. Do NOT use base plates/feet to determine whether or not unit
is level.

6. Unloading and Staging the Modules
NOTE: Concrete and gravel make the best staging ground.
NOTE: Leave adequate space between modules to attach platforms and catwalks.
1. Place modules on ground that is as solid and level as possible. Soft ground/grass will make
preparation for installation more difficult. Concrete or gravel ground is preferable for pre-installation
work. If no gravel or concrete area is available for staging the modules, consider placing the modules
on 2 x 4’s or other blocking material to prevent the modules from sinking into the ground.
2. Place modules next to sequential modules (i.e. place Module 2 near Module 3 and Module 3 near
Module 4, etc.) to make the stacking and connection of multiple modules easier.
3. Leave at least 4' to 5' of space between each module. Catwalks and/or platforms are attached
to appropriate modules before modules are stacked upon each other and lifted into place.
(See Figure 6A.)
Figure 6A Unload and Staging Considerations
PNEG-1708 GSI Modular Tower Dryer29
7. Placing and Installing the Base/Unload Module
Base/Unload Module Placement Considerations
If the concrete foundation is ready and adequately cured, place the base/unload module on it and take
careful and complete consideration of the surrounding equipment. Be sure to consider any planned
options such as augers and any potential equipment to be added later.
1. Consider the location of the electrical box and control panel. Orient base/unload module so that
personnel will have adequate and safe access to the electrical box and control panel. Remember,
the Vision control box can be remote mounted. (See Figure 7A.)
2. Consider any auxiliary equipment that will be used with the GSI Modular Dryer. One set of X-braces
on the unload may be removed without compromising structural integrity to allow for easier access.
3. Ensure that there is adequate overhead clearance for the entire tower dryer height and that the
clearance between the dryer walls and other equipment is sufficient to allow for catwalks
and/or platforms. (See Figure 7B on Page 31.)
Figure 7A
30PNEG-1708 GSI Modular Tower Dryer
7. Placing and Installing the Base/Unload Module
Figure 7B Consider overhead clearance for the entire height of the dryer.
4. Ladder brackets are not pre-installed on modules. Consider installation location of ladders and
brackets. Note that ladder brackets will be offset at each catwalk and will not line up in a straight line.
(See Figure 7C.)
IMPORTANT: When planning dryer location, ladders brackets will serve as good reference point for
where catwalks and/or platforms will be placed higher up on the dryer. Be sure to
allow for adequate spacing and clearance between the module dryer wall AND the
platforms and/or catwalks that will be attached higher up and any other equipment
in the area.
Figure 7C Ladder Brackets - Indentify location on each
module and surrounding equipment considerations.
PNEG-1708 GSI Modular Tower Dryer31
7. Placing and Installing the Base/Unload Module
CAUTION
While it is normal to encounter rebar on occasion when drilling the holes for anchor
bolts, should this happen more than 3 or 4 times, it is necessary to contact GSI for
splice plates to complete the drilling of the anchor bolt holes. (See Figure 7D.)
Securing the Unload Module
1. After determining the orientation of the unload module, use a 1-1/8" drill bit at least 12" long to drill
holes for the anchor bolts.
NOTE: Anchor bolts are 1" in diameter but the hole for them must be 1-1/8" in diameter to allow for
the required epoxy.
NOTE: It may be necessary to loosen or remove the bolts on the X-braces to gain easier access to
the holes for the anchor bolts. If X-braces are removed or loosened to drill the anchor bolt
holes, be sure to tighten the X-braces again when done.
Figure 7D
2. Use a laser transit to level the unload module.
IMPORTANT: ALWAYS use the compression channel as the point of reference for estab lishing
the levelness of the unit.
(See Figure 7E.)
Never use the feet/anchor plates to determine levelness.
Figure 7E
32PNEG-1708 GSI Modular Tower Dryer
7. Placing and Installing the Base/Unload Module
Do NOT remove more than one set of X-braces on the base/unload module as doing
so may compromise the structural integrity of the dryer . One set may be remove d to
accommodate auxiliary equipment.
NOTE: Shims are provided to assist with leveling if necessary.(See Figure 7F.)
Figure 7F
3. After drilling the holes, all debris and fine material must be removed from the holes.
4. Use a compressed air hose to blow the dust and debris out. Then, drop anchor bolt in holes to confirm
depth is adequate.
5. Once the unit is level, fill anchor bolt holes approximately 1/2" full with the provided epoxy. Press
anchor bolts in holes. (See Figure 7G.)
NOTE: Epoxy should ooze up and out of the hole at the base of the plate. If it does not, add epoxy
and repeat. No more than 2" to 3" of the bolt should remain above the plate. (See Figure 7G.)
6. After all anchor bolt holes have been filled with epoxy and all anchor bolts have been inserted into
the holes to the proper depth, allow epoxy to set for 4 to 6 hours before installing and tig htening nuts
or stacking another module of the dryer on top of it.
CAUTION
Figure 7G
PNEG-1708 GSI Modular Tower Dryer33
8. Assembling Ladders, Platforms and Catwalks
Crate as Work Bench
Because the base/unload module requires the epoxy to set for a MINIMUM of 4 hours before other
modules can be set on top of it, this is an excellent time to begin assembly of the ladders, platforms and
catwalks. Once the crate is empty, use a hammer to pound the exposed nails and/or staples back into the
frame so that the surface is smooth.
The crate makes an excellent work bench for assembling items throughout the installation process.
(See Figure 8A and Figure 8B.)
Figure 8A Crate as Work Bench
Once the modules have been staged, open the crate that shipped with the dryer modules.
The crate contains catwalk and/or platform materials, ladders and safety cages, as well as the hoses for
pipe train.
Optional items such as an auger kit will also ship in crates. Installation instructions for optional accessories
are in separate installation manuals.
Unload the materials from the crate and place them nearby in like-item groups (i.e. gas train pipes
together, catwalk and platform flooring together, etc). (See Figure 8B.)

Overview Catwalk and Platform Assembly
NOTE: This is a basic overview of the process as it relates to the Modular Tower Dryers and is intended
to be a general guide for catwalks and platforms as they are assembled on the GSI Modular
Tower Dryer.
Catwalk and platform parts are shipped in the shipping crate that accompanies the modules. Assemble all
floor planks and kick plates before assembling the dryer or stacking and connecting the modules. Use the
shipping crate as a work bench to assist in the assembly of kick plates, catwalks and platforms.
1. Match longer kick plates to longer catwalk platforms and match shorter kick plates to shorter
catwalk platforms.
2. Attach kick plates to planks with nuts and bolts. For safety purposes, all nuts should be to the inside.
3. Tighten fully with power impact. (See Figure 8M andFigure 8N.)

8. Assembling Ladders, Platforms and Catwalks
Attaching Catwalks and Platforms to Dryer Modules
Catwalks and platforms are attached to the appropriate modules while they are on the ground, before
modules are stacked on other modules or lifted into place on the unload module.
5. Remove four (4) bolts per seam on sections to attach catwalk support braces. Be careful not to push
bolts back into channel between the screens. If bolts are accidentally pushed back into the channel
when installing the catwalk support brackets, the easiest way to remove them is by creating an
extra-long handled wrench. An example of this is shown in Figure 8P. Attach a regular wrench to a
long pole, in this case one of the long safety cage bars was used. A crew member can then access
the bolt from the channel by reaching in with the extra-long wrench. Carpenter’s putty can be placed
on the end to help pick up the bolt if needed. The wrench can then be used to hold the bolt in place
back in the proper hole as it is re-tightened.

11. After attaching the catwalk brace to the catwalk brackets on the dryer wall, attach a catwalk transition
to the top of each catwalk brace. (See Figure 8X.)
IMPORTANT: Note the hole alignment on the catwalk transition. The “five (5) hole” pattern near the
center of the transition MUST be oriented so that the center hole is AWAY from the
dryer wall. (See Figure 8W andFigure 8X.)
Figure 8W
NOTE: Transition must line up on catwalk brace slot to slot. The SLOT indicated in the Figure 8W
must be oriented away from the dryer wall. Do NOT fill the middle hole of the transition.
13. There are two (2) planks between catwalk brace. The longer plank with the kick plate goes farther
away from the dryer wall with the kick plate on the outside and the shorter plank goes closest to the
dryer wall with the kick plate to the inside (to prevent stepping or slipping between the plank and the
dryer). (See Figure 8Y.)
Use nuts and bolts to connect catwalk planks to catwalk transitions.
Note in Figure 8Y only the inside plank has been places. It is located closer to the dyer wall. The
longer plank further from the dryer wall has not yet been placed and connected.
NOTE: Left nut is the middle hole mentioned in previous steps that had to be oriented away from
dryer wall. This is required so that the catwalk floor planks fit correctly. (See Figure 8Y.)
NOTE: Left nut shown in Figure 8Y is NOT in the correct slot.

19. When assembling catwalks and platforms be sure to leave open the area between seams where
ladder brackets are located. Ladders will be installed at these points to connect the platforms
and catwalks.
20. Attach ladder to roof module at this time, BEFORE lifting roof to be connected to other modules.
21. Do not attach other ladders at this time. Ladders for all other modules below the roof module will be
attached AFTER the roof module and/or other modules are lifted and placed.
PNEG-1708 GSI Modular Tower Dryer47
9. Burner/Blower Module - Special Considerations
1. Before lifting and stacking modules, be sure the floor planks are installed for the burner/blower
module. These should be factory installed. The burner/blower module contains flooring to support
the user when entering the dryer to perform cleaning or maintenance duties.
The flooring planks for the burner/blower module are similar to catwalk planks but have “TABS” on
the ends to drop into slots in the burner/blower module. (See Figure 9A.)
Figure 9A
In Figure 9A, one plank has been placed. Note the longer planks will be placed to the outside (closer to
the dryer wall) and the shorter planks to the inside (closer to the burner/blower).
In Figure 9B, multip le flooring planks have been installed along the outer portion (closer to the dryer wall).
The inner planks have yet to be placed.

NOTE: The plank nearest the thermistor housing will need to be cut to allow it to drop into place.
This should be factory installed.
In Figure 9C, the installer is marking the plank so that it can be field cut for proper fit.
Figure 9D shows the marks where the plank needs to be cut for proper fit.
Note the tabs and slots on burner/blower floor planks. This helps differentiate them from catwalk planks.

10. Lifting and Stacking the Modules
Overview for Safety
Before lifting any modules make sure the lifting capacity of the crane is adequate for the total combined
weight of the module or modules, as well as any attached accessories such as catwalks, platforms
and ladders.
•Roof = 2200 lbs.
•Turner = 2550 lbs.
•Heat = 1450 lbs.
•TM-1008 Blower section = 4000 lbs.
•TM-1010 Blower section = 4100 lbs.
•TM-1012 Blower section = 4200 lbs.
•TM-1015 Blower section = 4500 lbs.
•Unload = 6250 lbs.
rd
•Heat section with 15 channels = 1675 lbs. (3
•Catwalks = 1140 lbs.
Module on every dryer.)
NOTE: Section weights do NOT include the additional weight of the catwalk that will be attached to the
appropriate section(s). Catwalk weight is approximately 1140 lbs.
The GSI Modular Tower Dryer is designed for quick and safe on-site installation. In order to maximize
safety, always perform as much work as possible as close to the ground as possible. Use the illustration
guides included later in this section for reference.
All sections of the GSI Modular Tower Dryer come labeled by the factory. Separate labels identify the dryer
sections by name and by their sequential placement in the overall stacking of the Modular Tower Dryer.
To determine the weight of multiple sections when lifting them together, simply add the section weights
together and if applicable, add the weight of the catwalk as well.
NOTE: It is recommen ded to attach ladder to roof module BEFORE lifting roof off of ground. Attach ladder
to section below roof module AFTER roof module is placed upon it.
NOTE: 8' Ladder section will only be able to be attached after the section is stacked on another section.

replace step 4 with connecting Modules 3 and 2, stacking 3/2 on the base and then placing
Roof/4/3 on top of Base/2.
The GSI Modular Tower Dryer is designed to maximize safety and minimize assembly time. All models
will be assembled in similar fashion by: Lifting the roof module, stacking it on to the dryer module to be
directly underneath it and connecting those modules together. Then, the conjoin ed modules are lifted and
stacked on the next highest dryer module and connecting the modules. In this way, the vast majority
of work will be completed no more than ten feet (10') off of the ground. See the following figures on
Pages 52-55 for the specific recommendations for each model of the GSI Modular Tower Dryer.
NOTE: In all instances, six feet (6') lifting straps are recommended.

3. When maneuvering lifted modules across open ground, have personnel beside it to guide it and
minimize sway. When lifting the module on top of another module, be sure personnel have hard hats.
4. Carefully lower the module so that the connecting channels of each module are touching and can be
connected with nuts and bolts, however, do NOT lower fully at this time.
DO NOT REST THE UPPER MODULE(S) ON THE LOWER MODULE(S) AT THIS TIME. KEEP
SOME DEGREE OF TENSION ON THE MODULE FROM THE CRANE. ONLY FULLY LOWER
THE UPPER MODULE(S) ONCE ALL CONNECTIONS ARE MADE AT THE CONNECTING
CHANNELS WITH NUTS AND BOLTS.

5. Use the punches to line up connecting holes so that nuts and bolts can be loosely inserted at this time.
NOTE: Significant hammering and prying to accomplish hole alignment is to be expected.
Figure 10G
Figure 10H
NOTE: Ideally, crews will work in two (2) person teams with one team working inside the dryer and one
team working outside the dryer. Each person should have at least two (2) punches with narrow
pointed tips and long enough to provide significant leverage. Place step ladders and tools INSIDE
modules before stacking for ease of access.

7. Installation should proceed with a team of two (2) working to connect the modules from inside of the
dryer and two (2) working to connect the modules on the outside of the module.
For ease of assembly, place all tools, hardware and step ladders inside the module before stacking
another module on top of it.
Figure 10J shows a team of two (2) working to connect the modules on the inside.

8. On all models of the GSI Modular Tower Dryer, the first two (2) connecting seams - between the
base/unload module and Module 2 and between Module 2 and Module 3 - require a nut and bolt in
EVERY hole of the connecting channel, both INSIDE and OUTSIDE of the dryer.
a. For all other connecting seam after/above the first two (2), every other hole may be bolted.
OUTSIDE of dryer: Two (2) connecting channels between two (2) modules. (See Figure 10K.)
NOTE: Every connecting hole must have a nut and bolt in place.

10. Lifting and Stacking the Modules
14.4 Volt cordless impacts are NOT recommended for installation as they will
not sufficiently torque the bolts. Use electric impact and torque to 45 ft./lbs. If
bolts are not torqued properly, channels will co mpress when filled and bolts will
become loose.
Nut
9. Once all holes (or every other hole based upon which seam of the dryer you are working on at
the time) have a nut and bolt installed and are finger tightened, tighte n with an electric impact: torque
to 45 ft./lbs.
NOTE: When installing, in all possible situations, place the impact on the bolt. Do NOT tighten the
nut as it will not lock down on the ring. Always tighten the bolt. (See Figure 10M.)
NOTE: Accessing the bolts that connect sections of the dryer together requires passing through
the hole in the channel as shown. Narrow 3/8" drive sockets and/or extensions are required.
(See Figure 10L.)

11. Electrical Connections
Vision control panel
Electrical Overview Minimal Connections
One of the most beneficial features of GSI Module Tower Dryers is the fact that much of the electrical
wiring is done at the plant prior to shipping. This is an advantage for the customer as fewer electrical
connections need to be made in field, thereby making is a quicker and safer installation. The connections
to be made in the field by the customer are:
•Air switch
•Flame sensor and ignitor wires (spark plug)
•Bindicator, outside overheat and moisture sensor
•Plenum temperature
•Gas pipe train (natural or LP) overview minimal connections
Adjustable overheat honeywell thermostat capillary is ran up to burner section.
These connections are reviewed in greater detail this section.
Another advantage of the GSI Modular Tower Dryer is the ability of the vision control box to be remote
mounted. The control box can remain on the unload module as shown and shipped or if the customer
prefers, it can be remote mounted in a more convenient location for user access or to allow auxiliary
equipment access to the tower dryer.
If the vision control panel remains mounted on the unload module of the GSI Modular Tower Dryer,
the protective rain shield should be installed as shown in Figure 11A to help protect it from the elements.

12. Gas Pipe Train Overview
Gas Pipe Train (Natural or LP) Overview Minimal Connections
Another beneficial feature of the GSI Modular Tower Dryer is the fact that the gas pipe train comes
pre-fitted and pre-assembled from the factory. This minimizes the connections that need to be made in the
field. The result, is a quicker and simpler installation process.
Only three (3) connections need to be made in the field to complete the gas train. (See Figure 12B.)
Figure 12A
The three (3) connecting hoses for the gas train are for:
•Liquid in
•Vapor out
•Return to burner
All three (3) are shown in the Figure 12A and ship in the crate along with catwalks, platforms and
other hardware.
Each hose has unique fittings and can only be installed in the proper location.

13. Finishing Touches: Removing Wrinkles and Dents from Screens
During the installation process it is common for screen to “dent” or “wrinkle” from the pressures and
stresses of assembling. Examples of “denting” and “wrinkling” in the screens are circled in the Figure 13A.
They are often most visible in bright, reflective sunlight. Removing (or grea tly minimizing) these dents and
wrinkles is one of the final steps in the installation process. When removing wrinkles, work from the
top down.
1. Using all proper safety equipment and precautions, crew members should loosen the nuts on the
nearest columns one at a time until the “dent/wrinkle” literally “pops” out. Then, the nut(s) can
be re-tightened.
In Figure 13A, the columns in which the nuts should be loosened are between the arrow marks.
2. On occasion, it may be necessary to loosen the nuts connecting modules together. If this is the case,
ALWAYS re-tighten with impact when “wrinkle/dent” has “popped” out.
NOTE: In Figure 13A, the circles area highlights the wrinkle or dent in the dryer screen. The arrows
indicate the seams on which the nuts/bolts should be loosened to “pop” it out.
NOTE: New dryers ship with corrugated sheets.
