Tools and Materials Needed

Gather these essentials before starting:

  • Adjustable wrench
  • Pipe cutter
  • Voltage tester
  • Teflon tape
  • Wire strippers
  • 1/2″ NPT fittings
  • 8 AWG copper wire (for 13kW+ models)

For electrical work, consider hiring a licensed electrician if you’re unfamiliar with high-voltage wiring.

Step-by-Step Installation Guide

1. Choose the Right Location

Select a mounting spot that meets these requirements:

  • Within 50 feet of main electrical panel
  • Protected from freezing temperatures
  • Accessible for maintenance
  • Near water supply lines

Black and Decker units like the BD-POU-13HD model need at least 6″ clearance on all sides.

2. Mount the Unit Securely

  1. Locate wall studs using a stud finder
  2. Mark mounting holes from template
  3. Drill pilot holes
  4. Secure with provided screws

Ensure the unit is level before tightening completely.

3. Connect Water Lines

Follow these plumbing steps:

  1. Shut off main water supply
  2. Install isolation valves on both sides
  3. Connect cold water inlet (marked blue)
  4. Connect hot water outlet (marked red)
  5. Use Teflon tape on all threaded connections

For hard water areas, consider installing a descaling system to prolong heater life.

4. Electrical Wiring

Warning: This involves high voltage (240V). Turn off power at the breaker first.

Model Breaker Size Wire Gauge
7kW 2x 30A 10 AWG
13kW 2x 60A 6 AWG
18kW 2x 80A 4 AWG

Connect wires to corresponding terminals (L1, L2, Ground). Follow National Electrical Code for proper conduit installation.

5. Final Checks and Testing

  1. Open water supply valves slowly
  2. Check for leaks at all connections
  3. Turn on power at breaker
  4. Set desired temperature (typically 120°F)
  5. Test hot water at nearest faucet

Troubleshooting Common Issues

No Hot Water

Check these potential causes:

  • Tripped breaker
  • Insufficient water flow (minimum 0.5 GPM)
  • Faulty flow sensor

Water Not Hot Enough

Solutions include:

  • Increase temperature setting
  • Check for crossed hot/cold connections
  • Verify proper voltage supply

For persistent issues, consult the manufacturer’s support or a professional.

Maintenance Tips

Extend your heater’s lifespan with these practices:

  • Flush annually with vinegar solution
  • Inspect electrical connections yearly
  • Clean inlet filter every 6 months
  • Check for error codes regularly

Proper installation ensures your Black and Decker tankless water heater provides reliable, energy-efficient hot water for years to come.
