Do not hold the gas safety valve plunger in (open) for
more than 30 seconds. If the burner does not ignite
within 30 seconds, wait at least five minutes before
attempting to relight the burner. Holding the gas safety
valve plunger in (open) for more than 30 seconds will
allow propane gas to pocket in and around the burner.
An LP gas pocket in the burner area can cause a fire
or explosion which can result in extensive property
damage, burn injury and/or death.
