Operating Instructions

This section covers the basic operation of your Noritz NRCB199DV-LP combination boiler.

Control Panel Overview

The boiler features a digital display and control buttons for adjusting settings. Refer to the detailed operating manual for specific button functions and menu navigation.

Setting Domestic Hot Water (DHW) Temperature

Use the control panel to set your desired hot water temperature. The boiler will maintain this temperature for domestic use. Typical settings range from 100°F to 120°F (38°C to 49°C).

Setting Space Heating Temperature

The space heating temperature is typically controlled by an external thermostat connected to the boiler. Set your desired room temperature on the thermostat. The boiler will modulate its output to meet the heating demand.

Operating Modes

Your boiler may have various operating modes, such as:

  • Heating Only: Provides space heating without prioritizing DHW.
  • DHW Only: Provides domestic hot water without space heating.
  • Combi Mode: Prioritizes DHW when there is a demand, then switches to space heating.
  • Standby: The unit is powered on but not actively heating.

Consult your full operating manual for instructions on how to select and adjust these modes.
