1. What Fuel Type Do I Need?

Your gas log set must match your home's existing fuel supply.

• Natural Gas – Connected to a permanent gas line. Common in most suburban and urban homes.
• Propane – Uses a separate tank (above ground or buried). Common in rural homes and outdoor setups.

Important: Natural gas and propane burners are calibrated differently. Using the wrong fuel type can cause improper combustion and unsafe performance.

Most homes use the same fuel throughout the house. If you're unsure, check your utility bill or confirm with your provider before ordering.

2. Which Type of Gas Logs Should I Choose?

This decision comes down to one question:

Do you want maximum realism — or usable heat?

Vented Gas Logs

Designed primarily for appearance and realism.

• Large, natural-looking flames
• Install in open, wood-burning style fireplaces
• Require a working chimney with damper fully open
• Most heat escapes up the chimney

Best for: Homeowners who want the look and ambiance of a traditional wood fire and use the fireplace occasionally for atmosphere.

Vent-Free Gas Logs

Designed for efficient heat output.

• No chimney required
• More heat stays inside the room
• Flames are smaller and more controlled
• Must be installed in an approved vent-free firebox

Best for: Rooms that run cold, basements, large open spaces, or homeowners who plan to use the fireplace regularly.

Outdoor Gas Logs

Designed specifically for open-air environments.

• Built for patios and outdoor fireplaces
• Require stainless steel burners
• Not approved for indoor use

Important: If you have a sealed, fixed-glass direct vent fireplace, standard gas log sets will not work. Direct vent systems require manufacturer-specific components.

3. What Ignition System Should I Use?

This determines how your fire turns on, how convenient it feels, and how much gas it uses between burns.

• Manual Safety Pilot – Standing pilot with simple knob control. Reliable and straightforward.
• On/Off Remote – Push-button convenience.
• Variable Flame Remote – Adjust flame height from your chair.
• Electronic Ignition (Intermittent Pilot) – Pilot only lights when needed. More fuel-efficient.
• Thermostat Remote (vent-free only) – Maintains your desired room temperature automatically.

Most Popular Choice: Remote-controlled systems offer the best balance of convenience and control.
