Buying Guide
What to consider when choosing an LP gas fireplace insert
BTU needs by room size: larger rooms benefit from higher BTU, but avoid oversizing to prevent overheating. Ventless designs are easier to install but require adequate room ventilation per local codes.
Fuel flexibility: dual-fuel inserts offer a choice between natural gas and LP, useful during fuel supply changes. Confirm gas line compatibility and proper ventilation for your home.
Design and finish: choose between rustic log sets or modern brick liners to match interior decor. Authentic logs contribute to realism, while double doors and brick liners affect visual appeal and maintenance.
Controls and safety: remote controls with LCDs and auto-shutoff features simplify operation. Look for child lock features and thermostat modes for consistent comfort.
Space and installation: zero-clearance or recessed options suit wall-inset installations. Ensure sufficient clearance around the unit and compliance with building codes.
Maintenance: ventless units require periodic checks for gas connections and burner cleanliness. Inspect for soot buildup and test the remote’s responsiveness.
