Q: Stove top burners lite but only about half flame when set to high. Hot water heater is about the same – low flame. The furnace will light but immediately go out.
A: This happens most commonly for this reason: There is a part of the propane regulator subsystem that controls amount of propane in the event of a rupture of one of the propane lines and will slow down the flow or stop it completely. Try this before doing anything else: Shut off the propane valve, make sure all propane appliances are turned off, then SLOWLY open the propane valve. Check your stove to see if that resolved your issue.
