RealFyre Peterson 24-Inch Live Oak Gas Log Set – Vented
The RealFyre Peterson 24-Inch Live Oak set is a vented natural gas log set designed for masonry or existing vented fireboxes. The package includes a vented burner, grate, silica sand, glowing embers, a 12″ gas flexline, and damper clamp for installation.
Key performance notes: the set produces up to 90,000 BTU of radiant heat, emphasizing sustained warmth as the ceramic logs retain heat after flames go down. Operation is match-lit and requires an existing key valve. The six hand-painted ceramic logs are reinforced with steel rods, prioritizing durability and a realistic appearance.
Intended use and compatibility: suited for homeowners looking for a high-output, vented solution that preserves chimney draft. The vented design requires an open flue and proper chimney maintenance for safe operation.

Use case: fits homeowners seeking a compact ventless log option that pairs remote convenience with a high-efficiency vent-free burner, suitable for spaces where adding a vent is impractical.
HearthSense MO18HVL Natural Gas Vented Fireplace Logs Set
The HearthSense MO18HVL is a vented natural gas log set producing 45,000 BTU and rated to heat up to 1,650 sq. ft. It includes seven hand-painted Mountain Oak logs made from refractory ceramics, a bag of embers, iron grate, U-burner chassis, vermiculite, and hardware.
Operational notes: as a vented system, the flue must remain open during operation, directing combustion products outdoors. The design targets masonry fireplaces or vented fireboxes with minimum firebox dimensions specified for proper fit and performance.
Heat delivery and aesthetics: its higher BTU output supports larger spaces with radiant heat. The included embers and log arrangement focus on a realistic flame and glow while maintaining vented safety practices.
Dyna-Glo IR30NMDG-1 30,000 BTU Natural Gas Infrared Wall Heater
The Dyna-Glo IR30NMDG-1 is a wall-mounted infrared natural gas heater rated at 30,000 BTU and intended for up to 1,000 sq. ft. It heats by radiating energy to warm objects and people directly, similar to how sunlight warms surfaces.
Performance characteristics: infrared heating can be efficient in large open spaces or garage/workshop settings because it reduces the need to heat entire air volumes. The unit is built for natural gas and specifies that fuel conversion is not permitted.
Installation and clearance: wall mounting and clearance requirements must be observed. This unit is a fixed-installation heater rather than a decorative fireplace, aimed at functional space heating rather than ambiance.
Buying Guide: How To Choose A Natural Gas Fireplace Heater
Selecting the right natural gas fireplace or heater involves examining heat output, venting type, installation constraints, and safety. Below are the primary considerations to compare models effectively.
Vented vs. Ventless vs. Infrared
- Vented Systems: Require an open flue or direct vent; exhaust combustion byproducts outdoors. Typically offer a more traditional fireplace experience and high radiant heat for larger areas.
- Ventless (Vent-Free): Do not require a chimney; release combustion products into the room within regulated limits. Provide high indoor heat efficiency but may be restricted by local codes due to indoor air quality considerations.
- Infrared Heaters: Radiate heat to objects and people, efficient for targeted heating of workspaces or open rooms. Not a decorative fireplace substitute but effective for practical heating.
BTU Output And Coverage
- Match the unit’s BTU rating to the square footage and ceiling height of the space. Higher BTU units suit larger rooms or open-concept areas.
- Consider insulation, windows, and airflow. Manufacturer coverage estimates assume average conditions; verify by calculating heat loss if precise sizing is needed.
Installation Requirements And Compatibility
- Verify whether the product needs a masonry firebox, an existing gas line, or specific venting. Some log sets require a key valve or damper clamp included.
- Dual fuel models offer flexibility between natural gas and propane, which can simplify conversions or future fuel changes.
- Check local building codes and homeowner association rules for restrictions on ventless appliances.
Controls, Safety, And Efficiency
- Controls: Thermostat and remote controls support user convenience and more consistent temperature regulation.
- Safety Features: Look for certifications, standing pilot vs. electronic ignition, oxygen depletion sensors (for ventless models), and clearances required by the manufacturer.
- Efficiency: Ventless units often claim near-total heat delivery to the room. Vented units lose some heat up the flue but may provide better combustion venting and indoor air quality.
Aesthetics And Materials
- Ceramic fiber and refractory ceramic logs provide realistic appearance and heat retention. Hand-painted details and embers enhance realism.
- Consider mantles, surrounds, and finishes if the fireplace is a focal point. Some systems include furniture-grade mantles or brick liners for an integrated look.
Maintenance And Longevity
- Vented systems require chimney inspection and cleaning. Ventless systems need less exterior maintenance but require periodic inspection of burners and pilots.
- Replace or clean embers, check seals, and follow manufacturer service intervals to maintain performance and safety.
Comparison Perspectives
- Heat-First Users: Prefer higher BTU vented log sets or ventless units for maximum room warmth.
- Air Quality Concerns: Vented systems are preferable to minimize indoor combustion byproducts.
- Installation Flexibility: Dual fuel and ventless products reduce structural requirements but may need code approval.
- Decor vs. Utility: If ambiance is primary, hand-painted logs with realistic embers are important. If utility is primary, infrared or high-BTU units may be better.
When evaluating models, weigh installation feasibility, venting requirements, BTU needs, and local regulations. Use the product feature lists to match intended room size and desired operational characteristics before selecting a natural gas fireplace heater or log set.
