How To Check Water Heater For Carbon Monoxide: A Simple Guide

Carbon monoxide (CO) is a colorless, odorless, and toxic gas that can be fatal if inhaled. It’s often associated with gas appliances, including water heaters. Knowing how to check your water heater for carbon monoxide is crucial for your safety and well-being.

Why Check Your Water Heater for CO?

Water heaters can produce CO if they’re malfunctioning or not properly maintained. Symptoms of CO poisoning include headaches, nausea, dizziness, and confusion. In severe cases, CO can lead to loss of consciousness, brain damage, or even death.

Signs of a CO Leak

Before checking your water heater, be aware of the potential signs of a CO leak:

• A yellow or orange flame on your water heater
• Soot or black marks around the water heater
• A musty or stale odor
• Condensation on windows or walls
• Frequent headaches or nausea in your home

Tools You’ll Need

To check your water heater for CO, you’ll need:

• A carbon monoxide detector
• A screwdriver or wrench
• A flashlight

Step-by-Step Guide to Checking Your Water Heater for CO

1. Place the Carbon Monoxide Detector:

• Position the CO detector within 10 feet of your water heater.
• Ensure it’s at least 5 feet above the ground and away from any obstructions.

2. Turn on the Detector:

• Switch on the CO detector and allow it to warm up for a few minutes.
• The detector should emit a beep or flashing light to indicate it’s working.

3. Inspect the Water Heater:

• Use a flashlight to examine the water heater for any signs of damage or corrosion.
• Check the flue pipe and exhaust vent for any blockages or leaks.

4. Check the Flame:

• Remove the access panel on the water heater to reveal the burner assembly.
• Turn on the water heater and observe the flame. It should be blue and steady. A yellow or orange flame indicates a potential CO leak.

5. Tighten Loose Connections:

• Use a screwdriver or wrench to tighten any loose fittings or connections on the water heater.
• Ensure all gas lines and fittings are secure.

6. Clean the Burner:

• If the flame is not blue, it may be clogged with dust or debris.
• Use a soft brush or vacuum to gently clean the burner.

7. Check the Exhaust Vent:

• Inspect the exhaust vent outside your home to ensure it’s clear and unobstructed.
• Remove any leaves, debris, or snow that may be blocking the vent.
