To install a Titan water heater, first turn off power and water, then connect the water lines and electrical wiring according to the manufacturer’s instructions.
Installing a Titan tankless water heater requires careful attention to plumbing and electrical connections. This guide covers everything from mounting to final testing, ensuring a safe and efficient installation.
Tools and Materials Needed
Before starting, gather these essential items:
- 7/8″ wrench
- Drill with appropriate bits
- Level
- Pipe cutter
- 6AWG or 8AWG copper wire (depending on model)
- 1/2″ or 3/4″ copper/CPVC pipes
- Shut-off valves
- Sediment filter
- Pressure relief valve
Mounting the Water Heater
Choosing the Location
Select a spot near your main water lines and electrical panel. The Titan SCR-2 series requires vertical mounting with screws spaced 6 1/2 inches apart.
Installation Steps
- Mark screw locations on wall using the unit as a template
- Drill pilot holes
- Secure unit with provided screws
- Use a level to ensure proper alignment
Plumbing Connections
Pipe Requirements
Titan heaters work with 1/2″ or 3/4″ copper or CPVC pipes. The best tools for HVAC technicians include pipe cutters that ensure clean connections.
Connection Process
- Install shut-off valves on both inlet and outlet
- Connect cold water inlet (marked blue)
- Connect hot water outlet (marked red)
- Add sediment filter on inlet side
- Install pressure relief valve
Important: Never use Teflon tape on connections. Tighten nuts with a 7/8″ wrench to avoid damage.
Electrical Wiring
Wire Specifications
SCR-2 series models require:
| Model | Wire Size | Breaker Size |
|---|---|---|
| Titan N-120 | 6AWG | 60A |
| Titan N-85 | 6AWG | 50A |
Wiring Steps
- Turn off main power
- Run appropriate gauge wire from panel to unit
- Connect ground wire to breaker panel
- Install proper breaker (match unit requirements)
- Consider adding a disconnect box near unit
According to USA Tankless, improper wiring is the most common installation error.
Initial Startup and Testing
Water Flow Check
- Open cold water supply valve
- Open hot water faucet nearest unit
- Let water run for 20 seconds to purge air
- Check all connections for leaks
Power Activation
- Ensure unit has water flow
- Turn on power at breaker
- Set desired temperature (105-120°F recommended)
- Test multiple faucets to confirm operation
Maintenance Tips
Regular maintenance extends your Titan’s lifespan:
- Clean sediment filter monthly
- Check pressure relief valve annually
- Inspect wiring connections yearly
- Consider HVAC coil cleaner for mineral buildup
Troubleshooting Common Issues
No Hot Water
Check power supply, water flow, and reset button. The Titan’s digital microprocessor samples temperature 21 times per second for consistent performance.
Fluctuating Temperatures
Adjust flow rate or power mode. As noted on Tankless Water Heater, medium flow (1 GPM) provides optimal temperature control.
Safety Considerations
- Never weld pipes near installed unit
- Avoid excessive solder paste
- Don’t open unit casing (voids warranty)
- Install drip pans if required by code
The Titan’s 10-year warranty on water-carrying components makes it a reliable choice when properly installed.
