Robertshaw 1819-001 Drop-Out Pilot

Professional contractors and service technicians rely on the Robertshaw 1819-001 Quick Drop-Out Pilot for demanding LP gas applications where immediate safety response is mandatory. As a critical component of the Robertshaw 1800 Pilot Series, this assembly is engineered specifically for systems that require the rapid deactivation of the safety magnet upon loss of the pilot flame. This OEM-quality pilot assembly features a Type 4 hood configuration and comes equipped with 18-inch electrode leads and a 24-inch two-lead thermopile for versatile installation within a combustion chamber. The inclusion of an 18-inch Lo-Mass ODS thermocouple ensures high-precision sensing and quick thermal response times. When troubleshooting inconsistent ignition or safety circuit failures in liquid propane heating equipment, replacing the gas furnace pilot light assembly with this high-performance unit ensures the fuel supply is secured instantly if the flame is compromised, maintaining the integrity of the safety shut-off string.

Key Benefits for Contractors

• Optimized for LP Gas: Engineered to handle the specific combustion characteristics of liquid propane systems.
• Rapid Safety Response: Designed for quick dropout of safety magnet to prevent gas accumulation.
• Comprehensive Lead Lengths: Features 18-inch and 24-inch leads to accommodate various HVAC pilot assembly mounting positions.
• Enhanced Flame Sensing: Utilizes a Lo-Mass thermocouple for faster cooling and quicker millivolt drop-out signals.
• Standardized Compatibility: Direct fit for Robertshaw 1800 series configurations, reducing field modification time.

Common Technical Questions

What is the primary function of a "quick drop-out" pilot?
In high-safety LP applications, a standard drop-out time may be too slow. This assembly ensures the safety magnet releases the gas valve seat almost immediately after flame failure to mitigate hazard risks.

Which millivolt output components are included in this assembly?
The Robertshaw 1819-001 includes both a two-lead thermopile (750mV) and a Lo-Mass thermocouple (30mV) to power the safety circuit and the main operator simultaneously.

Can this pilot assembly be used for Natural Gas?
This specific model is calibrated for LP gas applications. Using it with natural gas would require an orifice change to maintain the correct BTU input and flame pattern.
