1. Schedule Annual Professional Inspections

Your gas fireplace is a complex appliance, and even if it seems to be working perfectly, hidden issues can arise. For residents in Southern MD, scheduling an annual professional inspection is the most crucial step you can take.

A certified technician, like the experts at SJ Johnson Company, will check:

Venting and Chimney: Ensuring clear exhaust and proper drafting.

Gas Lines and Connections: Looking for leaks or corrosion.

Pilot Light and Thermocouple: Testing for reliable ignition.

Burner Assembly: Cleaning and adjusting for peak efficiency.

This yearly service not only keeps your family safe by identifying potential hazards but also ensures your unit is operating at maximum efficiency, saving you money on your gas bill.

2. Clean Glass Doors Regularly

The glass doors on your gas fireplace can accumulate a white, hazy film, which is often a deposit from the gas combustion process. While primarily an aesthetic issue, excessive buildup can slightly impede the viewing and, over time, can make proper inspection of the burner difficult.

Safety Tip: Never clean the glass when the fireplace is hot. Always follow the manufacturer’s instructions for cleaning. Use a specialized gas fireplace glass cleaner—avoiding abrasive cleaners or ammonia-based products—and gently wipe to restore clarity.


3. Check for Gas Leaks with Soapy Water

While professional inspections are key, you can perform a simple check for small leaks where the gas line connects to the unit.

How to Check:

Mix a solution of dish soap and water.

With the pilot light off (consult your manual), brush the mixture onto the gas connections near the fireplace.

If bubbles form, it indicates a gas leak.


If you detect a leak or smell gas, immediately turn off the gas supply and call SJ Johnson Company or your local gas company. Do not operate the fireplace.


4. Keep Vents Clear of Debris

Gas fireplaces draw in combustion air and exhaust fumes through vents. If you have a direct-vent unit, the outdoor vent termination (usually a metal cap on the exterior wall) must remain unobstructed.

Make it a habit to:


  • Clear away leaves, snow, ice, or landscaping debris around the vent.
  • Ensure that children or pets cannot block the vent opening.
  • A blocked vent can cause combustion byproducts to backdraft into your home, posing a serious health risk.


5. Test Carbon Monoxide Detectors Monthly

The most important layer of safety is your carbon monoxide (CO) detector. CO is an odorless, colorless gas, making a functioning detector essential.


Action Item: Test your CO detectors monthly by pressing the "Test" button. Ensure you have detectors placed on every level of your Southern MD home, especially near sleeping areas and your fireplace. Replace the batteries twice a year, or the entire unit according to the manufacturer's suggested lifespan (typically 5-7 years).


Article Take-Aways

Following these five simple, expert tips is the best way to keep your gas fireplace operating safely and efficiently. For homeowners in Calvert, St. Mary's, and Charles Counties, prioritizing maintenance means enjoying the cozy warmth without worry. The most important step is scheduling your annual service with a trusted local provider to ensure your system meets all safety standards.
