How do you light a gas fireplace log?

Lighting a gas fireplace log can seem intimidating at first, but it’s actually a very straightforward process once you know the steps. In this comprehensive guide, we’ll walk through everything you need to know to safely and easily light your gas fireplace log every time.

Step 1: Check Your Gas Supply

Before lighting your gas log, it’s crucial to ensure you have proper gas supply and pressure. Here’s how:

• Make sure the gas line shut-off valve is open. This valve is typically located beside the fireplace.
• Check that the gas tank has enough propane, if your fireplace runs off propane.
• Inspect the gas line and fittings for leaks, damage, or obstructions. Fix any issues before proceeding.
• Test the gas pressure using a manometer. Pressure should measure between 7-14 inches of water column for natural gas or 11-14 inches of water column for propane.

If you detect any problems with your gas supply, call a professional to service the fireplace before use. Safety first!

Step 2: Clear the Fireplace

Before igniting the flame, the fireplace chamber and surrounding hearth need to be cleared of any debris. Here’s a checklist:

• Remove all logs, grates, and decorative media from inside the fireplace, if installed.
• Clear away all ashes, soot, and combustibles from the firebox.
• Clean out ember beds, log grates, and burner compartments.
• Vacuum the entire fireplace interior to remove dust, cobwebs, pet hair.
• Ensure the chimney flue damper is fully open to vent smoke.
• Double check that no combustible materials are within 36 inches of the fireplace.

Properly clearing the chamber prevents unwanted ignition and allows air flow for clean, efficient combustion.

Step 3: Examine the Burner Assembly

Gas log sets utilize a burner assembly that must be in good condition for safe functioning. Inspect yours closely:

• Check burner tubes and intake areas for cracks, blockages, or damage.
• Ensure grate bars, log supports, and ember bed covers are installed correctly.
• Verify the ignition source – a pilot light or electronic igniter – is present and operational.
• Examine all gas lines, valves, and connections for leaks using a soapy water test.
• Make sure burner surfaces and ventilation ports are clean and unobstructed.

Repair or replace any compromised burner components. A improperly functioning burner can cause dangerous backdrafting of gases into the living space.

Step 4: Arrange Decorative Media

For a visually appealing flame, decorative media like lava rock or glass crystals can be arranged around the burner. Position them carefully:

• Only use media approved for your particular gas log model.
• Place media in specified areas, like the ember bed compartment.
• Don’t overload media or block any burner ports, tubes, or ventilation areas.
• Leave spaces between pieces to allow proper air flow.
• Take care not to obstruct the pilot light or electronic igniter.

When in doubt, use media sparingly. Too much can restrict combustion and create a suffocation hazard.

Step 5: Install the Gas Logs

It’s time to put the decorative gas logs in place. Follow the log set’s placement instructions carefully:

• Use only the logs made for your specific gas fireplace make and model.
• Arrange logs according to diagram, without forcing or bending them.
• Align log undersides with burner ports beneath them.
• Leave recommended space between logs for flame travel.
• Keep logs away from walls, glass doors, log grate edges.

Balancing realism and proper spacing is key for gas logs. Well-situated logs ignite pleasing fire patterns.

Step 6: Turn On Gas Supply

Once everything is properly in place, you’re ready to turn on the gas:

• Confirm the gas line shut-off valve is in the open position.
• Bleed any trapped air from the gas line by igniting the pilot light briefly.
• Wait 5 minutes for any gas to dissipate, then smell for leaks.
• Turn the fireplace burner valve or switch to the “on” position.
• For propane units, very slowly turn on the gas at the tank.

Opening gas lines slowly prevents surges that could blow out a pilot light. With gas flowing, you can now ignite the fireplace.

Step 7: Light the Pilot Light

Standing adjacent to the fireplace, ignite the pilot light according to your burner’s specifications:

• Push the ignition button if you have an electronic igniter.
• Hold a long match or lighter wand near the pilot hood opening if manual.
• Continue holding the ignition source 30-60 seconds after the pilot light ignites.
• If the flame goes out, repeat while allowing more gas time to reach the pilot.
• Adjust the pilot light flame height as needed for proper ignition power.

A properly lit pilot provides a consistent flame to ignite the burner when called for. Never leave a pilot light unattended until stable.

Step 8: Turn on the Burner

With the pilot lit, you can now engage the main burner system:

• Turn wall switch or remote control to “on” to activate the burner valve.
• If using a manual valve, rotate it counterclockwise to allow gas flow until lit.
• Ensure the burner ignites evenly across all ports and tubes.
• Adjust valve or flame height to desired warmth and aesthetics.
• Turn off and re-light if any section fails to ignite promptly.

Observe the flame pattern closely the first few times, making adjustments as needed. The burner should ignite fully and burn cleanly along its entire length.

Step 9: Adjust the Flame Appearance

Part of the beauty of gas logs lies in the flame’s appearance. You can customize this by:

• Raising or lowering the gas pressure according to your appliance’s rating.
• Opening or closing the air shutter on the burner tubes.
• Spreading decorative media like lava rock for a fuller look.
• Adding fireplace glass crystals, log chunks, or colored glass for more color.
• Installing log sets with more realism and light-reflecting qualities.

Experiment to find your ideal balance of color, movement, and ambiance. Just take care not to sacrifice proper combustion.

Step 10: Extinguish the Fire

When it’s time to extinguish your gas logs, follow these shutdown steps:

1. Turn off the main burner by setting the valve, switch, or remote to “off.”
2. Close the main gas supply valve if the fireplace will be unused for an extended time.
3. For pilot lights:
   • Rotate the pilot valve to “off” to cut off the gas supply.
   • When cool, use a plastic or soft cover to cap the pilot opening.
4. For electronic igniters, simply turn off the ignition system.
5. Let embers cool completely before touching or cleaning them.

Allowing the firebox ample time to cool prevents burns and allows for cleanup. And remember to close the flue damper when the fireplace is not in use.

Gas Log Safety Tips

Lighting and maintaining your gas logs safely requires diligence. Keep these precautions in mind:

• Have your fireplace inspected annually by a professional.
• Clean the firebox, flue, and chimney regularly to prevent buildup.
• Always supervise children and pets around a hot fireplace.
• Use a fireplace screen to prevent accidental contact with the flames.
• Refrain from wearing loose clothing that could ignite.
• Allow fireplace components adequate time to cool before handling.
• Make sure the fire is completely extinguished before leaving the house.
