How to Light Pilot Light on Modine Gas Heater?

A pilot light is a small, continuously burning flame that is used to ignite the main burners of a gas appliance, such as a furnace or water heater. It is an important safety feature that helps to prevent the build-up of gas in the appliance and ensures that it can be safely and easily ignited when needed.

However, if the pilot light goes out, the gas appliance will not be able to operate properly. In this case, it is necessary to relight the pilot light to restore the appliance to proper working order.

When lighting the pilot light on a Modine gas heater, it is important to follow proper safety precautions and carefully follow the manufacturer’s instructions to ensure a safe and successful process.

Preparation

Before beginning the process of lighting the pilot light on your Modine gas heater, it is important to prepare the area and ensure that you are following proper safety precautions. The first step is to turn off the gas supply to the heater.

This can usually be done by turning a valve located near the gas meter or by pressing a button on the control panel of the heater. It is important to make sure that the gas is completely shut off before proceeding.

Next, you should make sure that the area is well-ventilated. This is especially important when working with gas appliances, as gas can be harmful if inhaled in large quantities. Open windows and doors to allow fresh air to circulate, and avoid using lighters or other open flames while working on the heater.

Once you have taken these precautions, you can proceed to the next step of locating the pilot light opening.

Locate the Pilot Light

To locate the pilot light on your Modine gas heater, you will need to look for the pilot light opening at the bottom of the heater. This opening is usually located near the gas valve and is covered by a small panel or access door. Depending on the model of your heater, you may need to remove a panel or access door to access the pilot light opening.

If you are having trouble finding the pilot light opening, you can refer to the manufacturer’s instructions or the label on the gas valve for guidance. You can also try looking for a small, glowing flame inside the opening, as this is a good indication that the pilot light is already lit.

Once you have located the pilot light opening, you can proceed to the next step of setting the gas controller to the pilot setting.

Set the Gas Controller to the Pilot Setting

To set the gas controller on your Modine gas heater to the pilot setting, you will need to refer to the manufacturer’s instructions or the label on the gas valve for guidance. The gas valve is usually located near the pilot light opening and is responsible for controlling the flow of gas to the pilot light and main burners.

To set the gas controller to the pilot setting, you will need to locate the appropriate setting on the gas valve. This may be labeled as “pilot,” “set pilot,” or something similar. Once you have found the correct setting, you can move the gas controller to this position.

If you are having trouble finding the pilot setting or are unsure of how to properly set the gas controller, you can refer to the manufacturer’s instructions or consult a qualified technician for assistance. Once you have set the gas controller to the pilot setting, you can proceed to the next step of lighting the pilot light.

Light the Pilot

To light the pilot light on your Modine gas heater, you will need to hold down the gas knob and use a lighter or match to ignite the pilot flame. The gas knob is usually located near the gas valve and is used to control the flow of gas to the pilot light.

To light the pilot light, follow these steps:

• Hold down the gas knob and press it inward to open the gas valve.
• Use a lighter or match to ignite the pilot flame. You may need to hold the lighter or match close to the pilot light opening for a few seconds to get the flame to catch.
• Keep the gas knob pressed down for a minute or two to allow the pilot to fully ignite. This will ensure that the pilot light stays lit and does not go out.
• If the pilot light does not stay lit, you may need to repeat this process until the pilot light remains lit.

Once the pilot light is lit and stable, you can proceed to the next step of returning the gas controller to the ON position.

Return the Gas Controller to the on Position

To return the gas controller on your Modine gas heater to the ON position, you will need to release the gas knob and set it to the ON position. The ON position is usually located on the gas valve and is used to allow the main burners to operate.

To return the gas controller to the ON position, follow these steps:

• Release the gas knob and allow it to return to its original position.
• Set the gas controller to the ON position. This may be labeled as “on,” “ignite,” or something similar.
• Once the gas controller is set to the ON position, the main burners should ignite within a few seconds.

If the main burners do not ignite, you may need to check the pilot light to make sure it is still lit and stable. If the pilot light is not lit, you may need to follow the steps for lighting the pilot light again.

Once the gas controller is set to the ON position and the main burners are ignited, you can proceed to the next step of testing the heater.

How Do I Reset My Modine Heater?

If your Modine heater is in lockout mode, there are two ways to reset it. The first method is to wait for the lockout to automatically reset after 1 hour. The second method is to manually reset the lockout by removing power from the control or removing the thermostat call for heat.

To manually reset your Modine heater, follow these steps:

Remove Power From the Control

Turn off the power to the heater at the circuit breaker or disconnect the heater from the electrical source. Wait for more than 1 second before restoring power to the heater

Remove the Thermostat Call for Heat

If removing power from the control does not reset the lockout, you can try removing the thermostat call for heat. This means turning off the thermostat or disconnecting it from the heater. Wait for more than 1 second and less than 20 seconds before restoring power to the thermostat

Restore Power to the Control and Thermostat

After waiting the specified time, turn the power back on at the circuit breaker or reconnect the heater to the electrical source. Then turn the thermostat back on or reconnect it to the heater

Check the Heater

Once power has been restored, check the heater to ensure that it’s functioning properly. If the heater is still in lockout, you may need to consult the manufacturer or a professional HVAC technician for further assistance

It’s important to note that the exact process for resetting a Modine heater may vary depending on the model and type of heater. Before attempting to reset the heater, it’s a good idea to consult the manufacturer’s instructions or a professional HVAC technician for specific guidance.

In conclusion, if your Modine heater is in lockout mode, you can reset it by either waiting for the lockout to automatically reset after 1 hour, or by manually resetting the lockout by removing power from the control or removing the thermostat call for heat. Before attempting to reset the heater, it’s a good idea to consult the manufacturer’s instructions or a professional HVAC technician for specific guidance.

Final Words

Taking off the panels should expose the pilot tube and thermocouple. Be sure to follow proper safety precautions when working with gas appliances, including turning off the gas supply and ensuring that the area is well-ventilated. If you are unsure of how to properly access or work on the pilot light and other components of your Modine heater, it is best to consult the manufacturer’s instructions or a qualified technician for assistance.
