1. What Fuel Type Do I Need?

Good news: most homes already have the answer.

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

The two options:

• Natural Gas: Common in most urban homes; connects to a permanent natural gas line.
• Propane: Uses a separate tank; common in rural areas or outdoor setups.

Quick reassurance:
Most homes use the same fuel type throughout the house. If you're unsure, check your utility bill or ask your gas provider.

2. Which Type of Gas Logs Should I Choose?

The right gas logs depend on where they'll be installed and how you want to use your fireplace.

Here's the simple breakdown: 

Vented Gas Logs

Designed primarily for appearance

• Produce large, realistic flames
• Require a working chimney or open flue
• Less heat output because heat escapes through the chimney

Best if you want the look of traditional wood fire, have a functioning chimney with an open flue, and prefer ambience over heat. 

Vent Free Gas Logs 

Designed to provide efficient heat.

• No chimney required
• Produce more usable heat for the room
• Must be installed in an approved firebox with proper clearances

Best if heating the room is a priority and your fireplace meets vent-free requirements.

Outdoor Gas Logs

Designed specifically for outdoor use

• Built for patios and outdoor fireplaces
• Must be paired with weather-resistant stainless steel burners
• Not intended for indoor use

Best for outdoor living spaces and open-air fireplaces

⚠️ Important Note About Direct Vent Fireplaces

Direct vent fireplaces are sealed systems and do not use standard gas log sets.

Standard vented or vent-free gas logs cannot be installed inside a direct vent fireplace.

Direct vent units require manufacturer-specific components designed for that exact fireplace model.

If you’re looking to replace or update the logs in a direct vent fireplace, American Gas Works works directly with a network of manufacturers and authorized suppliers and can help source and sell the correct replacement components for your specific unit.

If you’re unsure what model you have? Contact us and we’ll help you identify it and guide you through the next steps.

3. What Ignition System Should I Use for Gas Logs?

This is about how you want to control your fire. 

Popular options:

• Manual Safety Pilot – Simple knob control with a standing pilot 
• On/Off Remote – Push a button to turn the fire on or off 
• Variable Flame Remote – Adjust flame height from your remote 
• Electronic Ignition (Intermittent Pilot) – Pilot only lights when needed
• Thermostat Remote – (vent-free only) maintains your desired room temperature

 Quick tip:

If convenience matters, most customers choose a remote-controlled system.
