CAUTION
Check for leaks by spraying all connection points with
a soap solution made of dishwashing soap and water. If
you see soap bubbles, this would be an indication of a
leak and it should be corrected. Check each connection
point, there should not be a visible bubbling with the
soap solution applied. Refer to the “Fuel Pipe Sizing
Chart” contained in this manual or the Installation
Manual for your speci
fi
c HSB model. Installed
piping must be properly purged and leak tested, in
accordance with applicable codes and standards.
Champion HSB units have been run and tested at the factory
prior to shipment. They do not require any type of break-in
period.

tted with a dual Master Mixer Assembly
(carburetor system), which allows the HSB to run on either NG or
LPG. It has been con

gured at the factory to run on NG. If your
installation requires to run on LPG, an ori
fi
ce in the Master Mixer
Assembly (carburetor system) must be changed. The LPG ori
fi
ces
are shipped with the HSB.

3. Install the LPG ori
fi
ces (jets) in the mixing valve clockwise.
Tighten the low speed ori
