8. CHECkING PRESSURE WITH A MANOMETER
This check should only be done when the HSB and ATS have been
installed, properly inspected and ready for testing.
A Manometer is a general term for any device that measures
pressure. A gas manometer (1) measures gas pressure. It's
important to make sure the correct amount of fuel is being
delivered to the HSB when it starts and at full load usage, the
Manometer provides the ability to check the fuel pressure
throughout the operation of the HSB. A Manometer port should be
placed in the fuel supply pipe line.
Remove the plug, install the Manometer. Open the gas
supply valve check to make sure the pressures are within the
specified values for NG or LPG. This is always a good starting
point for evaluations related to poor performance.
After all appliances have been turn on, start the HSB. If the
Manometer stays within 5 -7 inches of water column for NG,
10 -12 inches of water column for LP, with full load applied to a
proper running HSB, the installation is good.
If the Manometer reading falls below the listed inches of water
column for either specific gas rating while the HSB engine is
starting or running. It may be an indication that the gas meter or
primary regulator is undersized.
If the Manometer reading stays within the specific gas rated
inches water column, but the HSB engine will not start, run erratic,
it may indicate insufficient fuel volume due to long fuel supply pipe
line, incorrect full pipe diameter. Recheck you initial calculations to
ensure where the problem might exist. Champion HSB units have
been run and tested at the factory. They do not require any type of
break-in period.
9. BATTERY REQUIREMENTS, INSTALLATION & SERVICE
Battery sizing is a topic that is discussed and debated for a
number of reasons. The battery size, cold cranking amps (CCA),
starting cycle or deep cycle are all items for consideration. The
following will assist you to better understand the battery, the
codes and the purpose of the battery. It is extremely important
to follow all cautions and warnings per the battery manufacturer
concerning installation, service, maintenance and replacement
procedures.

CAUTION
Battery Council International (BCI) is an association of battery
industry companies whose members establish policy and
standards for the industry.
Battery Size is the physical dimensions of a battery. BCI assigns
letters and numbers for North American battery size types.
Cold Cranking Amps (CCA) is a rating that is used to define
the batteries ability to start an engine under low-temperature
conditions. BCI defines it as "the number of amps a lead-acid
battery at 0 degrees F can deliver for 30 seconds".
Starting (cranking) Cycle Battery is designed to deliver large
bursts of power for a short time, as needed to start an engine.
Starting batteries are intended to have a low depth of discharge on
each use.
The starting system is a 24-volt DC system. The two 12-volt
batteries MUST be wired in series to achieve the correct
voltage.
Damage will result if the battery connections are made in
reverse, refer to owner manual or installation manual for
typical installation. Dielectric grease should be applied on
battery posts to aid in prevention of corrosion. Cables supplied
with the HSB.
This HSB is equipped with an automatic float type battery trickle
charger powered by utility power, to maintain full battery power
while in standby (non-running) mode. This trickle charger will not
recharge a fully discharged or defective battery.
When doing any work on the batteries always make sure the HSB,
ATS and transfer switch from utility are in the "OFF" position
or sparking may occur at the battery posts as the cables are
attached and cause an explosion.
Battery Requirements
For battery installation, maintenance, and safety requirements
refer to battery manufacturer's battery installation and safety
manual.
14-kW (Model 100515)
Two (2) 12-volt Group U1L batteries. Battery size: 7 3/4 L x 5 3/16
W x 7 5/16 H inches (196mm L x 131mm W x 185mm H). Purchase
batteries locally.
The recommended battery type for typical use is 350 CCA. This
is based on testing in extreme cold and heat -22° F (-30° C) to
104° F (40° C). However, a 300 CCA shown in the "Recommended
Battery Type" chart may be used for typical use, if in regularly
warmer climates.
