WARNING
Fuel presents the hazard of explosion or fire which can result in severe
personal injury or death. Do not use an open flame to check for leaks. Do not
smoke or allow any flame, spark, pilot light, arc-producing equipment, switch
or other ignition sources around fuel or fuel components. Keep multi-class
ABC fire extinguishers handy.
NOTICE
Follow any local codes and standards, as they may require a different
method or documentation of a leak test.
After assembly, and before initial operation, all fuel system connections, hose,
valves, regulators and fittings must be tested and proven free of leaks using a soap-
and-water (or equivalent) solution while the system is under gas or air pressure of at
least 1.5 times the supply pressure or 3 psi (20.7 kPa) minimum.
1. [Copied from GSBB Manual] Energize the fuel solenoid from a separate 12
VDC source before testing the fuel system.
2. Pressurize the system to a minimum of one and a half times the required fuel
supply pressure.
3. Spray the soap-and-water solution on all of the joints.
4. Inspect all of the joints and monitor the line pressure. If bubbles appear, there is
a leak.
5. If a leak is found, tighten the joints, recheck for leaks, and repair or replace
component(s) as needed.
4.3 Engine Exhaust
The exhaust system for this generator set is complete and was designed specifically
for this generator set. Do not modify or add to the exhaust system of this generator
set.
WARNING
Exhaust gas is deadly. Make sure that the exhaust system terminates away
from building vents, windows, doors, and sheltered spaces that may not
have ample fresh air ventilation.
WARNING
Engine discharge air and exhaust carry carbon monoxide gas (odorless and
invisible) which can cause asphyxiation and death. Never use engine
discharge air or exhaust for heating a room or enclosed space.
