The Hydrolevel 45-348 Wire Harness is a specialized electrical interface designed to facilitate a direct communication link between a Safgard Model 1100 Low Water Cut-Off (LWCO) and the United Technologies (UTC) Integrated Boiler Control Module. This heavy-duty harness is essential for HVAC technicians installing 24V residential boiler safety controls, providing a plug-and-play solution that eliminates the need for field splicing or complex terminal wiring. By utilizing the secondary port on the UTC controller, this harness ensures that the burner circuit is properly interrupted during a low water condition, maintaining system safety in accordance with modern boiler codes. This OEM-spec boiler wire harness is engineered specifically for atmospheric boiler applications and is not for use with induced draft models. The Hydrolevel 45-348 features high-quality Molex-style connectors that ensure a secure, vibration-resistant connection within the tight confines of a boilerÆs low-voltage wiring panel. Whether you are replacing a damaged harness or adding a 1100 series LWCO to an existing UTC-equipped system, this component ensures the low water cut-off installation remains reliable and technically compliant. Key Benefits Efficient Integration: Enables rapid connection of the Safgard Model 1100 directly to the UTC Integrated Control Module secondary port. Safety Compliance: Ensures immediate burner circuit interruption during low water events to protect the heat exchanger. Reduced Labor: Eliminates manual wire stripping and crimping, reducing the potential for field wiring errors. Professional Construction: Utilizes factory-standard connectors for a secure fit that matches internal boiler wiring. Common Questions Is the Hydrolevel 45-348 compatible with Honeywell controls? Yes, this specific harness is designed for use on boilers equipped with either the United Technologies (UTC) or specific Honeywell Integrated Boiler Control Modules. Can I use this harness on an induced draft boiler? No, this part is strictly intended for atmospheric boiler configurations. Forced or induced draft systems require different wiring configurations. Does this include the Low Water Cut-Off? No, this is the standalone wire harness. The Safgard Model 1100 LWCO must be purchased separately if you are performing a new installation.
