Starting the Pro - You depress this gas button to allow
gas to flow into the burner box to allow the unit to start. It is after
the unit is running and heat is generated that the gas valve will stay open
on its own and you can release is slowly.
Safety Valve - If the Pro overheats and it reaches a certain temperature
the gas valve will close and stop the flow of gas and shut off the Pro. (WARNING:
This gas valve should not be bypassed. Bypassing this valve can and will result
in damage to the Pro and would not be covered by the warranty.
