6. Check all connections for gas leaks using approved
gas leak detectors. Gas leak testing is performed as
follows:
• Check all pipe connections, hose connections, fittings,
and adapters upstream of the gas control with approved
gas leak detectors.
WARNING
Fire and Explosion Hazard
■ Do not use open flame (matches, torches,
candles, etc.) in checking for gas leaks.
■ Use only approved leak detectors.
■ Failure to follow this warning can lead to fires
or explosions.
■ Fires or explosions can lead to property
damage, personal injury or loss of life.
-- In the event a gas leak is detected, check the
components involved for cleanliness and proper
application of pipe compound before further
tightening.
-- Furthermore, tighten the gas connections as
necessary to stop the leak.
-- After all connections are checked and any leaks are
stopped, turn on the main burner.
-- Stand clear while the main burner ignites to prevent
injury caused from hidden leaks that could cause
flashback.
-- With the main burner in operation, check all
connections, hose connections, fittings and joints as
well as the gas control valve inlet and outlet
connections with approved gas leak detectors.
-- If a leak is detected, check the components involved for
cleanliness in the thread areas and proper application
of pipe compound before further tightening.
-- Tighten the gas connection as necessary to stop the
leaks.
-- If necessary, replace the parts or components involved
if the leak cannot be stopped.
-- Ensure all gas leaks have been identified and repaired
before proceeding.

for the application. A regulator must be connected
to the gas supply so that gas pressure at the inlet of
the gas valve is regulated within the range specified
on the dataplate at all times.
• The Commander heaters does not come standard
with a second stage regulator.
• Contact your gas supplier, or the L.B. White Co.,

the temperature sensor probe can fail. The
temperature sensor failure may result in an
underheating condition. If the probe fails, the
Temperature Controller will set the modulating
valve to 5VDC to continue to provide some heat to
the space. The sensor should be tested to ensure
the setpoint and the discharge air temperature are
within a temperature differential of ±3°F (±1.5°C).
