Have a Propane Gas Heater? Learn How to Maintain it Here


In the garage, on the patio, at a job site, and even camping in the wild, propane gas heaters have a wide variety of uses.

Economical, earth-friendly and effective, they can warm large spaces and even provide comfort outdoors when the weather turns cold.

If you've recently purchased a propane gas heating unit, or you're thinking about it, you may be wondering what you need to do to keep them working properly and extend the life of your unit.

Here is a basic guide to keeping yours operating in peak condition.

REMEMBER: All units come with an owner's manual. Be sure to read it thoroughly for specific safety and maintenance guidelines.

Checking for Leaks

Propane, also called Liquefied Petroleum or LP gas, is a byproduct of natural gas processing and crude-oil refining. It's non-toxic, colorless and odorless, but manufacturers add an unpleasant scent to it so you can detect a leak should one occur.

Your local propane supplier can provide a scratch and sniff card so that you can learn to recognize the smell. If you smell something that reminds you of rotten eggs, skunk, or dead animal, it means there's a leak in your unit's canister, hose or connector.

IMPORTANT: If you smell gas, do not attempt to light the unit or operate any electrical switches in the vicinity. Evacuate the area and notify your local propane supplier and the fire department immediately.

Regularly checking your heater for leaks is the best way to avoid serious injuries or health problems. Follow these simple steps every time a hose or tank is connected to your heater.

Next, check for faulty connections and leaks:

If you identify a leak, close the propane tank's valve. It might be possible to correct the leak by tightening the connectors or screws. Be careful of over-tightening, however, as you could damage the connector. If you're not sure, the best thing to do is contact your propane supplier to arrange a repair or replacement.

Checking the Burner

When using propane heating, it's a good idea to regularly inspect the pilot flame and burner flame. The pilot flame should be blue. If it burns with a yellow flame or an irregular flame, or you can see significant amounts of soot, then it probably needs cleaning.

Regular Cleaning

Keeping these heaters clean is the easiest way to prevent problems. It's recommended to clean the exterior every month, being especially careful to clear the air vents. The inside of these heaters should be thoroughly cleaned at the beginning of each winter season, or whenever it has gone unused for long periods of time.

Safety Warnings


Carbon monoxide is the odorless byproduct of burning propane and can be toxic to humans. Before using your heater indoors, make sure you have chosen a unit that is approved for indoor use and that adequate ventilation is provided.

Even when used under proper safety guidelines, it's important to regularly maintain your unit. If the pilot or burner has irregular flame, it might indicate that the gas is not burning completely, a situation that can lead to the creation of carbon monoxide.

Symptoms of carbon monoxide poisoning include headaches, dizziness, loss of muscular control, vomiting, and watering of the eyes. If you experience any of these symptoms while using your heater, turn off the unit, open a window and remove yourself from the location immediately.

These heaters are not difficult to properly maintain. Ensuring they are clean and everything is functioning as it should be it will operate safely and efficiently.

However, if you should determine that maintenance or repairs beyond those described in this article are needed, it is recommended that you contact the manufacturer or see a certified heater technician.
