A forced-draft gaseous pre-mix power gas burner having a shaped and perforated burner plate wherein the hole sizes are related to the plate thickness and the holes are formed in a unique pattern, all of which prevent flashback and noise or screech while at the same time flame stability is greatly improved. The burner plate is easily installed and removed, is essentially free from stresses which would distort it, and readily fits positively and accurately within the burner assembly without resorting to welding or other special fasteners. A novel ignition-improving device for effecting a stagnant flow at the ignition arc location provides for quick and reliable ignition of the gas at all times.
