Noritz NORNRC661-DV-LP Lp Tankless Water Heater

Product Description

The NORITZ NORNRC661-DV-LP is an indoor, direct-vent, liquid propane tankless water heater designed for residential installations. It delivers on-demand hot water by heating only when a fixture calls for flow, eliminating standby heat loss associated with traditional tank-style units. The unit is configured for liquid propane fuel and uses a direct-vent system that draws combustion air from outside and exhausts flue gases to the exterior, making it suitable for tight or unventilated mechanical spaces. Licensed plumbers and HVAC technicians handle installation and commissioning.

This unit is intended for indoor residential use in single-family or multi-unit dwellings where liquid propane is the available fuel source. The direct-vent configuration allows installation in interior utility rooms, closets, or mechanical spaces that do not have access to ambient combustion air. It is a demand-fired appliance, meaning flow activation triggers the burner assembly, and no energy is consumed during idle periods.

Key Features

• Liquid propane fuel configuration for homes without natural gas service
• Direct-vent design draws outdoor combustion air and exhausts independently of indoor air
• On-demand heating eliminates standby energy losses from stored hot water
• Indoor-rated enclosure suitable for interior mechanical rooms and utility closets
• Residential-class unit sized for whole-home or supplemental hot water supply

Compatibility

Designed as an OEM-style replacement or new-installation tankless water heater for residential liquid propane systems requiring an indoor direct-vent appliance.

Installation Notes

Installation must be performed by a licensed plumber or qualified technician in accordance with local plumbing codes, the appliance manufacturer instructions, and NFPA 54 or applicable LP gas codes. Shut off the propane supply at the service valve and depressurize the line before making any gas connections. Vent termination must comply with clearance requirements for combustion air intake and exhaust outlets. Do not attempt to convert this unit to natural gas; it is factory-configured for liquid propane only.
