4. LPG VAPOR PIPE SIZING
The HSB leaves the factory set up for NG. If you are going to fuel
the HSB with LPG you MUST change the Master Mixer Assembly
(carburetor system) for LPG usage. The HSB will not perform on
LPG if the carburetor system is not changed from NG to LPG.
Refer to "Converting to LPG" in this manual or the Installation
Manual of your specific HSB model. If your installation requires
the engine to run on LPG, a set of orifices in the Master Mixer
Assembly (carburetor system) MUST be changed. The LPG set of
orifices are enclosed (shipped) with the HSB.
The following LPG information is provided to assist the fuel
installer. This information should not be deemed to be all
inclusive or to conflict with local dry fuel codes. Consult your
local fuel supplier or Fire Marshall for final answers on proper
local codes and installation. All piping must comply with NFPA
54 and related codes. Gas line connections should be made by a
certified plumber familiar with local codes.
DANGER
!
LPG is highly explosive. Even the
slightest spark can ignite and cause
an explosion, which could cause
burns or fire resulting in serious
injury, property damage or even
death. No leakage is permitted.
Safety is important.
Gas pipe sizing is critical to the proper operation of the HSB. The
HSB fuel inlet size has no bearing on the proper gas pipe size
running to the HSB. Gas supply and pipe MUST be sized at 100%
load Btu rating.
Pipe sizes are measured by inside diameter (ID) to include any
fittings, valves, elbows, tees or angles. Add 2.5 feet (.76 m) per
any bend, tee or angle in the pipe to the overall distance. For
each 90 degree elbow, add 8 ft. (2.4m) to the measurement.
Use a pipe sealant or joint compound for use with LPG/NG on all
threaded fitting to assure zero leakage.

INSTALLATION
The LPG must be a vapor withdrawal system. The HSB will not
work on a liquid withdrawal system. Gas line connections should
be made by a certified plumber familiar with local codes.
New LPG tanks and existing LPG tanks already located at the
installation site, have a primary fuel regulator set and intended
for home heating and cooking. This regulator might not be
properly sized to accommodate the addition of the HSB. Contact
the local LPG supplier to properly size the fuel regulator. Make
sure the tank is sized large enough to provide the required Btu's
for the HSB and all connected appliances.
The LPG fuel tank must have a dedicated primary fuel regulator
mounted at the tank fuel outlet point and set for 6 ounce
pressure, 10 -12 inch water column. A direct, dedicated fuel
line connected directly to the HSB mounted secondary regulator,
also set at 6 ounce pressure, 10 -12 inch water column. When
sizing the secondary regulator for LP applications be sure to note
the maximum individual load capabilities. This could impact HSB
starting performance if sized to small. It is not recommended
to reduce the fuel supply line pipe exiting the secondary
regulator unless to accommodate the flexible fuel line required
to install and shipped with the unit. The may result in starting or
performance issues with the HSB.
Make sure fuel supply line pipe includes an on/off external
manual full flow shut off gas valve at both the LPG tank and at
the point of connection to the HSB.
A sediment trap should be installed into the fuel supply pipe line
to drain any condensation.
FLEXIBLE FUEL LINE
A flexible fuel line (enclosed with the HSB) is to be installed
between the stationary fuel supply line pipe and the fuel inlet
pipe to the HSB. The purpose of the flexible line is to ensure
that vibration from the HSB does not cause a gas leak at one of
the connection points. The flexible fuel line is not to be installed
underground, in contact with any enclosure parts or contact
with the ground. The entire fuel line must be visible for periodic
inspection and must not be concealed within not contact nor run
through any wall, floor, partition or fence. Never bend a flexible
fuel line to avoid using an elbow. Bending the flexible fuel line
decreases its ability to absorb vibrations and could constrict the
actual fuel flow. Because the HSB engine is prone to vibration, a
flexible piping connection to the gas supply is required. Connect
the HSB to the gas supply piping with an approved flexible gas
line according to local codes. The flexible gas line also protects
against settlement between the HSB pad and the ridged gas
supply piping.
