Laars Heating Systems RS2109100 Gasket Set
The Laars Heating Systems RS2109100 Gasket Set is a critical replacement component for NeoTherm series boilers and volume water heaters. This OEM Laars gasket kit is engineered for high-temperature environments, providing a gas-tight seal for the NeoTherm burner door, ignitors, and flame sensors. Maintaining a proper seal is essential for preventing combustion gas leaks and ensuring optimal condensing boiler efficiency. This set is specifically designed for NeoTherm NTH and NTV models ranging from 80 to 850 MBTU/h, including NTH-150, NTH-210, NTH-285, NTH-399, NTH-500, and NTH-600. Using genuine RS2109100 gaskets during annual maintenance prevents the common issues of heat exchanger fouling and irregular combustion patterns associated with degraded sealing surfaces.
Key Benefits- Comprehensive Sealing: Includes the burner gasket, ignitor gasket, sensor gasket, and burner door gasket for a complete combustion chamber overhaul.
- Precise Fitment: Engineered specifically for Laars NeoTherm NTH and NTV series to maintain factory air-to-fuel ratios.
- High-Temperature Durability: Constructed from professional-grade materials capable of withstanding the thermal cycling of high-efficiency condensing heating systems.
- Improved Safety: Eliminates the risk of carbon monoxide bypass and flue gas leakage at the burner assembly.
Is the burner door gasket rubber or fiber?
The RS2109100 kit typically includes the specialized rubber door gasket designed for the NeoTherm's sealing groove, though components may vary based on specific model year updates. Always cross-reference your specific MBTU size.
Can I reuse my existing gaskets if they look intact?
Standard service protocol for Laars Heating Systems dictates that gaskets should be replaced whenever the burner door is opened for heat exchanger cleaning. Distorted or compressed gaskets will not provide the 0.0" w.c. to positive pressure seal required for safe operation.
Which NeoTherm sizes does this kit fit?
This NeoTherm gasket set is compatible with residential and commercial models. It is the standard service kit for units from 80 MBTU/h through 850 MBTU/h, though larger commercial units (750-850) should verify the part number for technical revisions.
