Hydrotherm 70-6700 Ignitor Assembly

The Hydrotherm 70-6700 Ignitor Assembly is a high-performance direct spark ignition component engineered specifically for Hydrotherm KN-2 boilers and various gas-fired heating systems. Designed for heavy-duty commercial and residential applications, this assembly features a durable ceramic insulator and high-temperature alloy electrodes that withstand the taxing environment of a gas combustion chamber. By replacing an aged or fouled boiler ignitor, technicians ensure rapid, consistent flame establishment, which is critical for maintaining fuel efficiency and preventing delayed ignition cycles that can lead to system lockouts.

This OEM replacement part serves as a direct substitute for the Hydrotherm 70-6700, integrating seamlessly into existing burner configurations without the need for extensive field modifications. Its precision-gapped electrode design facilitates a robust spark across the pilot or main burner, optimizing the combustion system performance. For contractors performing preventative maintenance or emergency repairs, this assembly provides a reliable solution to common ignition failures, ensuring the heating system operates at peak safety and reliability throughout the peak heating season.

• Precision Engineered: Specifically tuned for the Hydrotherm KN-2 series, ensuring exact alignment and electrode spacing.
• High-Temperature Durability: Constructed with materials designed to resist thermal shock and oxidation in high-BTU burner environments.
• Improved Efficiency: Facilitates instantaneous spark ignition, reducing fuel waste associated with delayed start-ups.
• Reliable Operation: Minimizes nuisance service calls by providing a consistent discharge across all operating cycles.

• Is this compatible with the KN-2 boiler series? Yes, this specific assembly is the designated part for the Hydrotherm KN-2 models and related gas-fired units.
• Does this include the high-voltage lead? This assembly typically consists of the ceramic block and electrodes; verify your existing lead condition during installation.
• Can this restore a system from a "No Flame" lockout? If the controller is sending voltage but the burner fails to light, replacing a worn or cracked 70-6700 ignitor often resolves the issue.
