INSTALLATION. FAILURE
TO DO SO MAY CAUSE
SERIOUS INJURY OR
DEATH
Fuel Warning

they have been purged according to procedures of the National L. P. Association.
Be sure fuel supply system complies with all local codes for L. P. gas installations.
DO NOT USE FLAME FOR LEAK TESTING.

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 feet away. This
ground needs to be as close to the fan as possible,
but no more than 8 feet away. The ground rod
should be connected to the fan control panel with
at least a #6 solid bare 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 neces-
sary for long life and operation of the solid state
Machine to Earth Ground
Dig a hole large
enough to hold 1
or 2 gallons of
water. Work the
ground rod into
the earth until it
is completely in
the ground.
It is recommended that previ-
ously installed units be checked
to see that a machine to earth
ground has been installed by an
electrician.
(Ground rods and wires are not supplied by GSI
). It is recommended that the rod not be driven
into dry ground. The following steps ensure proper
ground rod installation:
1. Dig a hole large enough to hold 1 to 2 gal-
lons of water.
2. Fill hole with water.
Proper Installation of the Ground Rod
5. Connect the bare copper
ground wire to the rod with
the proper ground rod clamp.
6. Connect the bare ground wire
to the fan control boxes with
a grounding lug. See Figure
3
7. Ground wire must not have
any breaks or splices. Insu-
lated wire is not recom-
mended for grounding.
Figure 1: Use a #6 or approved size bare copper ground wire.
Install a 5/8" diameter 8' long copper-clad ground rod, 2' away
from the foundation and 1' below the surface of the ground or in
accordance with local requirements.

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 com-
pletely into the ground. This
method of installing the rod
gives a good conductive bond
with the surrounding soil.
