Description
The Laars Heating Systems RW2013400 is an OEM replacement Flame/Sensor Gasket engineered to maintain a secure, leak-free seal around the flame sensor assembly in compatible Laars boilers and water heaters. Proper sealing at the flame sensor port is critical to safe and efficient combustion — a worn or damaged gasket can allow flue gas leakage, compromise sensor accuracy, and trigger nuisance lockouts. Replacing this gasket during routine maintenance or sensor service restores the integrity of the combustion chamber and helps ensure reliable ignition and flame-proving performance.
Key Features
- OEM Laars Heating Systems replacement part (SKU: RW2013400)
- Designed to seal the flame sensor port on compatible Laars boiler and water heater models
- Helps prevent flue gas bypass and maintains accurate flame-sensing operation
- Supports reliable ignition sequencing and reduces nuisance lockouts
- Recommended replacement during flame sensor service or combustion chamber maintenance
Application
- Compatible with select Laars Heating Systems boilers and water heaters — consult your equipment manual or Laars parts documentation to confirm fitment for your specific model
Why Replace Your Flame/Sensor Gasket?
Over time, gaskets exposed to high-temperature combustion environments can harden, crack, or compress, losing their ability to form an effective seal. Replacing the RW2013400 gasket at the first sign of wear — or as part of a scheduled tune-up — helps protect equipment longevity, maintain combustion efficiency, and keep your system operating safely within manufacturer specifications.
