Gas Log Set Buying Guide

Vent-free or ventless gas log sets are a great choice if you are looking for the highest heating efficiency possible. They’re a superb supplemental heating source when used in an approved vent-free firebox or wood-burning fireplace with the damper closed. Since vent-free gas logs produce moisture, it’s important they’re properly sized for the room you use them in. Download and complete the Air Combustion and Ventilation Worksheet and check with local building codes to make sure a vent-free gas appliance is an appropriate option for your application.

• Use in approved vent-free fireboxes, and factory-built and masonry wood-burning fireplaces
• Do not use in factory-built fireplaces that state unvented gas logs should not be used
• No venting required; however, adequate air must be available for combustion and ventilation
• 9% heat efficiency offers exceptional zone heating capabilities
• Required oxygen depletion sensor (ODS) ignition pilot is included on all vent-free gas log burners that automatically shuts off unit if oxygen levels drop below an 18% safety threshold
• Millivolt control models offer reliable on/off operation with remote control capabilities
• Electronic ignition control models feature gas-saving intermittent pilot ignition (IPI) and seamless battery backup that provides continued operation in the event of a power failure

• Outdoor-specific models with stainless-steel burners and grates are also available

Primarily chosen for decorative applications, vented gas log sets offer the ambiance of a traditional real wood fire with the convenience of gas. Since these log sets are only approved for use in fully vented wood-burning fireplaces that can withstand higher temperatures, they are able to burn with larger, more realistic flames and embers. Electronic ignition models combined with remote controls bring another level of convenience. Vented gas log sets also eliminate the work and mess associated with building, tending and cleaning up after a wood fire.

• For use in fully vented and operational wood-burning fireplaces only
• Fireplace must be operated with glass doors and damper in fully open position
• Used in decorative applications due to low, less than 10% heating efficiency
• Match-light models available for natural gas applications (safety pilot kits required for LP gas)
• Electronic ignition control models feature gas-saving intermittent pilot ignition (IPI) and seamless battery backup that provides continued operation in the event of a power failure
• Wall switch, on/off remote controls and multifunction remote controls are available for easy control of electronic ignition models
• A variety of highly detailed logs available with realistic wood grain textures and colors
• Outdoor-specific models with stainless-steel burners and grates are also available
