Laars Heating Systems RW2001800 Pilot Assembly

The Laars RW2001800 Pilot Assembly is a precision-engineered Natural Gas pilot designed specifically for the Laars Mighty Therm and Pennant series boilers and water heaters. As a direct OEM replacement part, this assembly ensures consistent electronic ignition and reliable flame rectification for atmospheric heating systems. The heavy-duty construction is built to withstand high combustion chamber temperatures, preventing premature thermal fatigue of the pilot burner and electrode. For contractors performing preventative maintenance or emergency repairs, this assembly simplifies the restoration of stable millivolt signals and proper main valve sequencing. Integrating this genuine Laars replacement maintains the original equipment’s UL/CSA certification and ensures the flame sensor operates within the manufacturer's specified microamp range. Accurate alignment of the pilot orifice and electrode gap minimizes nuisance lockouts, providing the long-term reliability required in light-commercial and residential hydronic heating applications.

Technical Specifications and Benefits

• Direct OEM Compatibility: Verified for use in Laars Heating Systems models, ensuring exact mechanical fitment and gas flow rates.
• Simplified Field Installation: Pre-configured pilot tube connection and electrode positioning reduce labor time during HVAC service calls.
• Reliable Igniter Performance: Engineered for consistent spark-to-pilot ignition, preventing delayed ignition cycles and combustion rumble.
• High-Temperature Durability: Robust metallurgy prevents warping of the pilot head under high-fire conditions.

Common Installation Questions

Is the RW2001800 compatible with Propane (LP) units?
No, this specific assembly is calibrated for Natural Gas applications. Using this in an LP configuration will result in improper combustion and potential safety hazards.

Does this assembly include the high-voltage ignition lead?
Yes, the Laars RW2001800 typically includes the integrated electrode and lead wire required for connection to the ignition module.

What are the signs that a pilot assembly needs replacement?
Persistent boiler lockout codes, visible carbon buildup on the thermopile or sensor, and inconsistent spark intensity are primary indicators that the assembly has reached its service life limit.
