performed as follows:
WARNING
Fire and Explosion Hazard
■ Do not use open fl ame (matches, torches,
candles, etc.) in checking for gas leaks.
■ Use only approved leak detectors.
■ Failure to follow this warning can lead to fi res
or explosions.
■ Fires or explosions can lead to property dam-
age, personal injury or loss of life.
-- Check all pipe connections, hose connections,
fi ttings and adapters upstream of the gas control
with approved gas leak detectors.
-- In the event a gas leak is detected, check the
components involved for cleanliness and proper
application of pipe compound before further
tightening.
-- Further 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 fl ashback.
-- With the main burner in operation, check all
connections, hose connections, fi ttings 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 leak.
-- If necessary, replace the parts or components
involved if the leak cannot be stopped.
-- Ensure all gas leaks have been identifi ed and
repaired before proceeding.
