Abstract
A gas burner includes a gas reservoir, a combustion device, and a tilt safety device fluidly connecting to one another. The tilt safety device includes first and second seats including first and second gas passages respectively, an elastomer disposed on the second seat and including a section defining a stop, a control mechanism including a lever adjacent to the elastomer and including a first contact area and at least one second contact area selectively engaging with a pusher which engages with the stop, and a gas flow channel connecting to the second gas passage and a hole extending through the elastomer and the first gas passage and including the first and second ends thereof including the stop disposed therebetween. The first and at least one second contact areas space from the elastomer at first and second heights respectively. The second height is less than the first height.
