No LP to the stove top.

Appliances that utilize propane are at times difficult to fire up, particularly when propane supply has been turned off for extended periods of time. Under this scenario in many cases air needs to be purged from LP supply lines before appliances will ignite. After turning on propane at tank, I turn burners on let air in lines purge lighting stove when I detect propane coming from burners, doesn't take long.
