User Manual for Drija 17L Gas Water Heater

Quick guide from the manual

The Drija 17L Gas Water Heater (Model CLT17L) is a forced-type gas water heater designed for residential hot water supply. Important: Installation must be performed by a registered gas installer. The unit requires a well-ventilated area, a reliable grounding device for the electrical connection, and proper flue pipe installation to exhaust waste gas outdoors. Always ensure the gas type matches the rating label (LPG: 2800Pa).

Safety Precautions

• Do not install in bedrooms, basements, living rooms, or bathrooms without proper ventilation and flue pipe exhaust.
• If a gas leak is detected, close the main gas valve, open windows and doors, and do not operate electrical switches.
• Keep flammable materials at least 250mm away from the heater.
• Always check hot water temperature by hand before showering to avoid scalding.
• Do not touch the flue duct during or immediately after operation.

Main Components

The unit features a control panel for temperature settings, a water flow adjustment knob, and clearly marked inlets/outlets for water and gas. The exhaust vent is located at the top of the unit.

Installation

Installation must be done by a registered gas installer. Key requirements include:

• Location: Well-ventilated room with a floor drain. Avoid installation in bedrooms, basements, or living rooms unless specific distance requirements are met.
• Mounting: Fix the heater vertically to the wall with screws, maintaining at least 10mm distance from the wall.
• Piping: Ensure the flue pipe is installed to discharge exhaust outdoors. The gap between the pipe and the wall should be sealed with a 1° leaning angle to prevent water backflow.
• Connections: Confirm gas inlet, water inlet, and water outlet connections are secure and leak-free.

Operation Instructions

1. Ensure the gas supply is on and the gas regulator is qualified.
2. Open the main gas valve and the water inlet/outlet valves.
3. Plug the unit into a grounded electrical outlet.
4. Open the hot water tap; the heater will ignite automatically.
5. Use the control panel to set the desired temperature (35°C to 65°C).
6. Adjust the water flow volume using the knob at the bottom if necessary.
7. Close the hot water tap to turn off the flame.

Maintenance

Regular maintenance ensures safe operation:

• Before maintenance, close the gas and water valves and unplug the power.
• Wipe the exterior with a soft towel and kitchen cleanser (do not use benzene or thinner).
• Regularly remove and clean the filter at the water inlet using a toothbrush.
• Check for any abnormal sounds or changes in appearance during operation.

Troubleshooting

If the heater does not operate correctly, check the gas and water supply valves first. If the indicator light is off, check the power connection. If the water is not warm enough, adjust the water flow or temperature settings. The unit features an LED display that shows error codes for specific malfunctions (e.g., E0 for probe malfunction, E1 for ignition failure, E3 for overheat protection).
