Niagara Industries supplies each heater with a mounting kit containing four sheet metal screws and two supporting brackets. These brackets can be attached to the back of the heater, allowing the installer to secure the heater to the wall without needing to open the front cover.

Make sure to only use the brackets and screws provided in the mounting kit. The use of longer screws may damage the unit.

The units are designed to be installed using copper pipes with 1/2″ or 3/4″ dimensions depending on the model. Follow these guidelines:

1. Excessive heat from soldering on copper pipes near the heater may cause internal damage to the unit.

2. Always flush all water lines before connecting the unit to the copper pipes.

3. After the unit is installed, open each hot water faucet slowly to allow air to vent from the water heater and piping.

4. Do not use Teflon tape or plumbing paste on compression fittings.

5. Install a shut-off valve in both the inlet and the outlet of the unit for ease of service.

6. Secure the unit to the wall utilizing only the brackets and compression fittings provided.

7. The unit requires vertical installation only.

When using any type of plastic pipe like PEX or CPVC, you must install 36 inches of copper pipe to both the inlet and outlet of the unit. Do not connect any plastic pipe directly to the unit. Additionally, when using plastic pipes, you must install a pressure relief valve on the inlet.

Before beginning any work on the electric installation, ensure the main breaker panel switch is “OFF” to avoid electric shock. All mounting and plumbing must be completed before proceeding with the electrical hook-up. As with any electric appliance, failure to electrically ground the unit may result in serious injury.

The breaker should be of the same size as the energy consumption of the model being installed. Make sure that all connections are tight and do not forget to install the ground wire to the main breaker panel.

Before you energize the unit, allow water to circulate for approximately 20 seconds to make sure the unit doesn’t work dry, which may damage the heating elements. Do not turn on the power with the shutoff valves closed.

Locate the water heater in a clean, dry area as near as practical to the area of greatest heated demand. Do not install the water heater in outdoor, unprotected areas. The water heater must be installed in a visual area with easy access to the water shutoff valves and the power disconnect box. A minimum of 12 inches clearance must exist from the top of the unit to the ceiling and from the bottom to the floor.

The Mode (white) button switches between 3 or 4 modes depending on the model:

Voltage: This is the default mode and shows the voltage being consumed and the percentage it represents from the total voltage. When the voltage is at 100%, the heater is working at full capacity.

Current: Shows the current being used and the percentage it represents from the total current. Displayed in Amps (A).

Power: Shows the amount of energy being consumed (Voltage x Current). Displayed in Kilowatts (KW).

Temperature: Available only on the Titan N-160, this shows the temperature coming out of the water heater in Fahrenheit (F).

Use the Red Button to increase the temperature of the water. Use the Blue Button to decrease the temperature of the water. Note that the water has to be running through the unit in order to adjust the temperature. The lower the setting, the greater the savings in energy and operating costs.

It is highly recommended that the heater be installed in an area that provides sufficient water drainage to prevent damage to walls, baseboards, appliances, and other fixtures. If no floor drainage is available, a drip pan with a minimum depth of 1 inch should be installed below the water heater and connected to a suitable drain. Alternatively, a proper leak detection system and shut-off components should be incorporated into the installation.
