Utica Boilers DXL820503240303 Hot Water Gas Boiler 205 Mbh

Product Description

The UTICA BOILERS DXL820503240303 is a mid-efficiency, atmospheric-combustion, gas-fired hot water boiler built around a proven cast iron heat exchanger. Rated at 205 MBH input capacity with 84% efficiency, it is designed for residential and light-commercial hydronic heating systems. The boiler ships with a circulator pump, ASME relief valve, combination temperature/pressure gauge, and a 3/4-inch drain valve already installed. Electronic ignition with a 24-volt intermittent pilot control and a motorized vent damper contribute to energy savings over standing-pilot designs. Installation and service access are simplified by a low-profile integral draft diverter and a pull-out burner drawer with a removable burner tube tray.

This boiler is suited for forced hot water heating applications vented through an existing masonry or listed chimney vent. The internal Hydrolevel operating control modulates water temperature based on system demand, reducing unnecessary burner cycles. A built-in low water cutoff (LWCO) protects the heat exchanger from low-water conditions. The unit is factory-wired with a complete gas control system including stainless steel burners, an automatic redundant combination gas valve, and a combination pilot burner, electrode, and sensor assembly. Licensed HVAC and plumbing contractors typically handle installation and commissioning.

Key Features

• Cast iron heat exchanger with dry leg end sections for long service life
• Pull-out burner drawer and removable burner tube tray for fast field service
• Low-profile integral draft diverter reduces installation height by up to 30% versus models with external diverter hoods
• Internal Hydrolevel operating control adjusts water temperature to match heating system demand
• Built-in LWCO protects against potentially dangerous low-water conditions
• Flame roll-out safety shut-off and manual reset, plus blocked vent safety shut-off
• 20-year non-prorated limited warranty on the heat exchanger

Compatibility

Designed as an OEM-style atmospheric hot water boiler for chimney-vented residential and light-commercial hydronic heating systems requiring a 205 MBH input capacity at mid-efficiency.

Installation Notes

Installation must be performed by a licensed HVAC contractor or plumber in accordance with local codes, the International Fuel Gas Code (IFGC), and the boiler manufacturer's installation manual. Shut off gas supply and electrical power before servicing any components. The chimney vent connector and flue must be properly sized and inspected prior to operation. Do not modify the factory-installed gas train, LWCO wiring, or relief valve piping.
