How to Adjust a Natural Gas Pool Heater

Easy Steps to Adjust Your Natural Gas Pool Heater for Optimal Performance

Adjusting a natural gas pool heater is an essential task that every pool owner should know how to do. A well-adjusted pool heater ensures that your pool water is at the desired temperature, making it comfortable to swim in. In this step-by-step guide, we will show you how to adjust a natural gas pool heater.

Step 1: Turn off the Heater
Before you start adjusting your natural gas pool heater, you need to turn it off. Locate the on/off switch on your heater and turn it off. Make sure that the heater has cooled down before you start adjusting it.

Step 2: Locate the Thermostat
The thermostat is the device that controls the temperature of your pool water. It is usually located on the side of the heater. Once you have located the thermostat, turn it to the desired temperature. Most pool owners prefer to keep their pool water temperature between 78 and 82 degrees Fahrenheit.

Step 3: Adjust the Gas Valve
The gas valve regulates the flow of gas to the heater. If the gas valve is not adjusted correctly, it can cause the heater to produce too much heat or not enough heat. To adjust the gas valve, locate it on the side of the heater and turn it clockwise to increase the gas flow or counterclockwise to decrease it.

Step 4: Adjust the Air Shutter
The air shutter controls the amount of air that enters the combustion chamber. If the air shutter is not adjusted correctly, it can cause the heater to produce too much carbon monoxide or not enough heat. To adjust the air shutter, locate it on the side of the heater and turn it clockwise to decrease the air flow or counterclockwise to increase it.

Step 5: Check the Burner Flames
The burner flames should be blue and steady. If the flames are yellow or flickering, it indicates that the heater is not burning the gas properly. This can cause the heater to produce carbon monoxide. If you notice any issues with the burner flames, you should contact a professional to service the heater.

Step 6: Turn on the Heater
Once you have adjusted the thermostat, gas valve, and air shutter, it's time to turn on the heater. Locate the on/off switch and turn it on. Wait for a few minutes for the heater to start producing heat.

Step 7: Monitor the Temperature
Monitor the temperature of your pool water to ensure that it reaches the desired temperature. If the temperature is not increasing, you may need to adjust the gas valve or air shutter again.

In conclusion, adjusting a natural gas pool heater is a simple task that every pool owner should know how to do. By following these steps, you can ensure that your pool water is at the desired temperature and that your heater is functioning correctly. If you encounter any issues, it's best to contact a professional to service your heater.
