1
Identify when the gas smell occurs
Pay attention to timing and pattern::
- Does the smell appear only when hot water is running?
- Is it stronger near the heater or gas pipe?
A smell that appears during operation often points to internal heater issues, while a constant smell may indicate gas pipe or joint problems.

Look, but don’t touch
From a safe distance, look at:
- The gas pipe and joints
- Any rust, stains, or damage
These usually point to internal components overheating or burning.

3
Check how the heater behaves
Pay attention if:
- The heater takes longer to start
- You hear unusual sounds
Automatic gas heater shutdown often happens when the heater detects unsafe conditions.
-
4
Check the ventilation area
Look around the heater:
- Is the exhaust pipe loose or blocked?
- Is the area stuffy or poorly ventilated?
Poor airflow can cause gas-related smells to build up.
⚠️ Important: ❌ Do not open the heater. ❌ Do not touch gas connections
