This low pressure cast iron burner puts out approximately 56,500K BTU. Designed to work at 11" WC of pressure for LPG and 7" WC for NG, it can burn either natural gas or LPG propane. It includes a shutter for air mixture control. Rather than concentrating all of the heat in one place like jet and ring burners, this burner spreads the heat out over a larger area. It is very quiet (you almost can't hear it when it's burning natural gas) and is very heavy duty: it weighs an amazing 15 1/2 pounds!

• Accepts a 1/4" MPT orifice or orifice/valve. (Not included, see related items)
• Heavy Duty cast iron (15 1/2 lbs!)
• 4 mounting lugs spaced every 90º, 11" across the lugs

What is WC Pressure?  WC stands for Water Column and is measured in inches.  It is a measurement of pressure under 1 PSI.  Most gas companies deliver gas to your home at between 7" to 11" WC.  27.7" WC is equal to 1 PSI.
