Roof Damage Warning and Disclaimer
CAUTION!
Excessive vacuum (or pressure) may
damage roof. Use positive aeration
system. Make sure all roof vents are
open and unobstructed. Start roof
fans when supply fans are started.
Do not operate when conditions exist
that may cause roof vent icing.
DC-969
GSI does not warrant any roof damage caused by excessive
vacuum or internal pressure from fans or other air moving
systems. Adequate ventilation and/or “Makeup Air” devices
should be provided for all powered air handling systems. GSI
does not recommend the use of downward flow systems (suction).
Severe roof damage can result from any blockage of air
passages. Running fans during high humidity/cold weather
conditions can cause air exhaust or intake ports to freeze.
DC-1224
Rotating flighting will
kill or dismember.
Flowing material will
trap and suffocate.
Crusted material will
collapse and suffocate.
Keep clear of all augers.

3. Heater Installation
Machine to Earth Ground
It is very important that a machine to earth ground rod be installed at the fan. This is true even if there is
a ground at the pole 15'away. This ground needs to be as close to the fan as possible, but no more than
8'away. The ground rod should be connected tothe fancontrol panel withat least a#6 solidbare copper
ground wire, or in accordance with local requirements. The machine to earth ground provides additional
safety if there is a short. It also provides the grounding necessary for long life and operation of the solid
state circuit boards used on control circuits and the electronic ignition systems.
Figure 3A
Dig a hole large enough to hold one (1) or two (2) gallons of water. Work the ground rod into the
earth until it is completely in the ground.
Proper Installation of the Ground Rod
(Ground rods and wires are not supplied by Airstream). It is recommended that the rod notbe driven into
dry ground. The following steps ensure proper ground rod installation:
1. Dig a hole large enough to hold one (1) to two (2) gallons of water.
2. Fill hole with water.
3. Insert rod through water and jab it into the ground.
4. Continue jabbing the rod up and down, the water will work its way down the hole, making it possible
to work the rod completely into the ground. This method of installing the rod gives a good
conductive bond with the surrounding soil.
