The Suburban 010799 is the OEM replacement burner assembly for the SF-42, SFV-42, SH-42, and SHD-2542 series of Suburban propane-fired RV furnaces. The burner is the core combustion component — it mixes propane and combustion air and sustains the flame that heats the heat exchanger. Over time, burners can accumulate corrosion, rust, or carbon deposits, or suffer physical damage, leading to ignition failures, incomplete combustion, or erratic flame behavior. Replacing the burner assembly restores proper combustion and heating efficiency.
This is a direct OEM replacement manufactured by Suburban Manufacturing. Dimensions are 8.5" L × 2.8" W × 1.2" H, weight is 1 lb.
The burner access door gasket is not included with the 010799 burner assembly and must be ordered separately. Two gasket versions exist depending on your furnace's serial number — confirm your serial number before ordering a gasket: Gasket 070811 (new p/n 525010): For furnaces with serial numbers below 094101431. Gasket 071263 (new p/n 525031): For furnaces with serial numbers above 094101431. Suburban serial numbers manufactured after January 1990 are nine digits. The first two digits indicate the year of manufacture, the next digits indicate the week, and the remaining digits are the serial number. The serial number label is located on the furnace unit itself.
Suburban furnace model numbers include letter suffixes that indicate configuration. All suffix combinations of the SF-42, SFV-42, SH-42, and SHD-2542 use the same 010799 burner assembly.
