GASEOUS
FUEL
Check with your supplier for local regulations cover-
ing the use and handling of gaseousfuel supplies and
equipment. Seal gas line connections with shellac or
some other compound approved for use in gaseous
fuel systems. Thread-sealing compounds with a lead
base are not satisfactory. Engines with electric con-
trols may require a solenoid primer and
a
shut-off
valve.
Install a manual shut-off valve as the first component
in the supply line. Install a “dry gas” filter and fuel
solenoid valve if recommended by your gas supplier
or local code. Install the demand-type regulator
according to the instructions supplied. Use shortest
.
possible hose between the regulator and carburetor
for best starting. See Figure

OIL
DRAIN EXTENSION
For service convenience, install an oil drain extension
in the
1/2
inch pipe-tapped oil drain hole in the oil
base. Use standard
112
inch pipe and fittings.
BATTERY
Mount the battery on a wooden or metal rack near the
engine. Air circulation around the battery is essential.
Use battery cables of proper length to limit voltage
drop. Coat connections on the battery with vaseline
or grease to prevent corrosion.

BATTERY CONNECTIONS
On engine with flywheel alternator, ground the
negative terminal of the batteries to the engine.
Failure to ground the battery negative ter-
minal will result
in
destruction
of
the selenium
rectifiers.
Connection of battery .positive terminals depends on
the type of starting
motor used for cranking, as
follows:
1.
Bendix (standard on cranking models):
Connect
positive from a suitable source of DC to start
switch. Connect negative
to
a good ground on
engine.
2.
Solenoid Shift (optional on cranking models):
Connect positive from a suitable DC source to
B+
terminal on start solenoid. Connect negative to a
good ground on engine.
3.
Auto-cycle (optional on cranking models):
12
volt
DC and
120
volt AC starters have
2
wire connec-
tions through a sensing device for automatic
starting.
