Staying warm during the colder months can be a challenge, but with a Comfort Glow propane heater, you can enjoy cozy comfort in your home or office. However, properly lighting and operating this type of heater requires some knowledge and attention to safety. In this comprehensive guide, we’ll walk you through the step-by-step process of lighting a Comfort Glow propane heater, along with essential technical specifications, maintenance tips, and troubleshooting advice to ensure your heater operates safely and efficiently.

Preparing to Light the Heater

Before you begin the lighting process, it’s crucial to ensure the area is well-ventilated and free of any open flames or sparks. Propane heaters require proper airflow to function safely, so make sure there are no obstructions or potential ignition sources nearby.

Next, locate the manual shutoff valve, which is typically found on the propane tank or gas line. Ensure this valve is fully open, allowing the gas to flow freely to the heater.

Igniting the Pilot Light

  1. Turn the Control Knob: Locate the control knob on your Comfort Glow heater and turn it clockwise to the “Light” or “Pilot” position. This will allow the gas to flow to the pilot light.

  2. Ignite the Pilot: Most Comfort Glow heaters are equipped with an igniter button or switch. Press and hold the igniter button while slowly turning the control knob counterclockwise to the desired temperature setting. You should hear a click and see a spark, indicating the pilot light has been ignited.

  3. Maintain the Flame: Continue holding the igniter button for about 20-30 seconds to allow the thermocouple to heat up and maintain the gas flow to the pilot light. This ensures the pilot light stays lit and the heater can operate safely.

  4. Adjust the Flame: If the pilot light goes out, repeat the ignition process. Once the flame is stable, you can adjust the heat output by turning the control knob counterclockwise to increase the heat or clockwise to decrease it.

Technical Specifications

Comfort Glow propane heaters come in a range of BTU (British Thermal Unit) outputs, typically ranging from 10,000 to 40,000 BTUs per hour. The specific BTU output of your heater will depend on the model you have.

Many Comfort Glow heaters also feature a built-in thermostat, allowing you to precisely control the heat output and maintain your desired temperature. This can be particularly useful for energy-efficient heating and consistent comfort.

In addition to the thermostat, Comfort Glow heaters often include safety features such as an automatic shutoff in case the pilot light goes out, and a tip-over switch that turns off the heater if it is knocked over. These features help ensure the safe operation of your propane heater.

Maintenance and Troubleshooting

To keep your Comfort Glow propane heater running smoothly, it’s essential to perform regular maintenance tasks. This includes:

  1. Checking for Leaks: Regularly inspect the propane tank and gas line for any signs of leaks. You can use a soap and water solution to check for bubbles, which indicate a leak.

  2. Cleaning the Heater: Over time, dust and debris can accumulate on the heater, affecting its performance. Regularly clean the heater according to the manufacturer’s instructions to maintain optimal efficiency.

  3. Replacing the Pilot Assembly: If the pilot light frequently goes out or the heater is not working properly, it may be time to replace the pilot assembly. This is a relatively simple DIY task that can be done with a few tools and a new pilot assembly, which can be purchased from a home improvement store or online.

By following these maintenance and troubleshooting steps, you can ensure your Comfort Glow propane heater continues to provide reliable and efficient heating for your home or office.


Lighting a Comfort Glow propane heater may seem daunting at first, but with the right knowledge and attention to safety, it can be a straightforward process. By following the step-by-step instructions, understanding the technical specifications, and performing regular maintenance, you can enjoy the cozy warmth and convenience of your Comfort Glow heater all season long.

Remember, safety should always be your top priority when working with any gas-powered appliance. If you have any doubts or concerns, it’s best to consult a professional for assistance.
