Frequently Asked Questions - ECF19i50 Rinnai
Can the Rinnai ECF19i50 be installed outdoors?
No, the ECF19i50 is designed for indoor installation only. It requires a suitable exhaust vent to the outside. For outdoor models, consider a Rinnai Infinity outdoor series.
What is the minimum water pressure needed?
The ECF19i50 works with a minimum 15 psi water pressure. Ensure your mains supply meets this requirement for proper flow detection.
How do I turn on the water heater?
Simply open a hot water tap. The heater automatically ignites when it detects water flow. The digital display shows the current temperature. To adjust, press the up/down buttons on the control panel.
What maintenance does the unit require?
Regular maintenance includes cleaning the water inlet filter and periodically flushing the heat exchanger to remove scale buildup. It is recommended to have a professional service the unit every year.
Does this heater work with solar pre-heated water?
The ECF19i50 is designed for cold water input, but it can handle pre-heated water up to 60°C from a solar system. However, this may reduce the temperature rise capability.
How do I reset the heater after a shutdown?
If the unit shuts down, turn off the power supply, wait for 5 minutes, then restart. If the error code persists, consult the manual for specific error diagnostics.
What temperature is recommended for safe bathing?
For household use, a setting of 40-45°C is recommended to prevent scalding. The heater can be adjusted from 35°C to 60°C.
Can I use an external recirculation pump?
Yes, the ECF19i50 is compatible with external recirculation pumps. Consult the installation manual for proper configuration and sizing.
What does the warranty cover?
Rinnai offers a 5-year warranty on the heat exchanger and a 2-year warranty on other parts. Labour costs are not included. Register your product to activate the warranty.
How do I descale the heat exchanger?
Descaling should be done by a qualified technician using a descaling pump and vinegar solution. The process involves connecting the pump to the service ports and circulating the solution.
