Verify that the current gas meter is capable of
providing enough fuel flow to include
household appliances and other loads
including the addition of the HSB. Check the
NG primary regulator, connected at the NG
meter output. The correct primary regulator is
set at 6 to 8 inches water column. The existing
primary regulator may be undersized once the HSB is
added.
The HSB engine can run on either NG or LPG. The HSB comes equipped from
the factory to run on NG. If your installation requires the engine to run on
LPG, orifices in the master mixer assembly (carburetor) MUST be changed.
The LPG orifices are shipped with HSB. Refer to “Converting to LPG” in this
manual or the “Installation Manual” for your specific HSB model.
10 wires from gen to ATS with a minimum rating of 300 volts.
This is a quick installation guide that is designed to assist in the installation of a
Champion Power Equipment Home Standby Generator, please always refer to the
installation manual of the unit you are installing and comply with local code.

Champion recommends using a mixture of pea gravel and sand or crushed stone for
placement of the mounting pad. The mounting pad MUST be level. The gravel mixture
or crushed stone is to permit water runoff, drainage and reduce ponding of water
around the HSB.
Dig an area 5 inches (12.7 cm) deep that is 6 inches (15.2 cm) longer and wider
than the foot print of the HSB. The HSB is 49 inches long X 28 inches wide
(124.5 cm long X 71 cm wide).
Cover the dugout area with a weed barrier
or landscape cloth if desired.
Fill the area with pea gravel and sand
mixture or crushed stone. Final stone level
must be 2 or 3 inches higher than the
original ground level to ensure water
run-off and drainage. Compact the fill, this is to provide a firm base for the HSB.
Remember the final stone level must be 2 or 3 inches higher than the original ground
level to ensure water run-off and drainage.
A concrete pad can be poured and the HSB secured to it. In some areas a concrete
pad is required due to high wind potential. Check local codes to see what type of
mounting base is required. If a concrete pad is required, all federal, state and local
codes should be followed. Unless mandated by federal, state or local code,
a concrete pad is not required.
Compliant with clause (2) of section 4.1.4 of NFPA 37 for installation of a minimum
distance of 450mm (17.7 in) from a combustible wall.
