SunPak 22004-1 (22004 1) Infrared Burner Assembly for all SunPak S25 heaters. If your SunPak S25 heater makes a loud bang and/or a helicoptering noise, the chances are you will need a new burner assembly. These burners will last longer if the SunPak heater is not tilted over 30 degrees from straight down. In other words the heater needs to point more down than sideways. If your S34 heater is too hot (as installed) you can order this burner with an orifice and convert it to an S25.
