If you’ve ever noticed a dark, velvety film creeping across the glass of your gas fireplace, you’re likely dealing with sooting. For owners of a Majestic Ruby gas insert, this isn’t just a cleaning nuisance—it’s a sign that your log set is out of alignment.

Here is a quick guide on why “close enough” isn’t good enough when it comes to log placement.

Why Precision Matters
The Majestic Ruby series is designed for complete combustion. This means the flame is engineered to dance around the logs without actually “impinging” (touching) them directly for extended periods.

The Science of Soot: If a log is shifted even a half-inch out of place, it can intercept the flame. This cools the flame down before it can burn the gas completely, resulting in carbon deposits (soot) that bake onto your glass.

Airflow Obstruction: These units rely on specific air-to-fuel ratios. Misplaced logs can block ports on the burner, causing the flame to “starve” for oxygen and turn smoky.

The “Golden Rules” for Your Ruby Set
1. Locate the Pins and Tabs
Majestic designs their burners with specific locating pins or notches. Each log has a corresponding hole or groove on the bottom. If the log isn’t seated firmly on that pin, it is incorrect. Never “free-hand” the placement.

2. Mind the “Glow” Path
The glowing embers (rock wool) should be placed thinly over the burner ports. If you pile them too high or use them to prop up a log, you’ll disrupt the flame pattern and end up with a blackened door.

3. Check the “Tine” Alignment
If your model uses a log grate, ensure the logs are tucked behind the grate tines as specified in your manual. A log leaning too far forward will cause ghosting flames that lick the glass directly.

Signs Your Logs Are Misaligned
Dark Spots: Black carbon buildup on specific areas of the logs.

Lazy, Yellow Flames: Flames that look “oily” or unusually smoky rather than a crisp, vibrant orange/blue.

Rapid Glass Fogging: If you have to clean your glass every three days, something is physically blocking the burner’s path.

Pro Tip: Always let the unit cool completely before adjusting. Even a minor tweak to a top “twig” log can be the difference between a crystal-clear view and a soot-covered door.
