Frequently asked questions
Vented vs. ventless gas logs — which is right for me?
Vented gas logs require a working chimney/flue (open damper during use). They produce a more realistic, taller flame and expel combustion byproducts outdoors. Ventless (vent-free) gas logs burn cleaner so they don't require a flue — but they release combustion moisture and trace byproducts into the room. Vented = more realistic look + fully outdoor exhaust. Ventless = higher heat efficiency + flexible install but check local codes (some jurisdictions restrict ventless).
Are ventless gas logs safe?
Ventless gas logs sold in the US must include an oxygen depletion sensor (ODS) by design — the unit shuts off automatically if room oxygen drops below safe levels. Most also include built-in carbon monoxide protections. To use safely: install a CO detector in the room, follow the BTU sizing limits for your room volume, crack a window if running for extended periods, and don't run continuously for more than the manufacturer's stated maximum (typically 4 hours). Some states and municipalities do not permit ventless installation — check your local code.
Can I use gas logs in my wood-burning fireplace?
Yes — vented gas logs are designed to drop into a working masonry or pre-fab wood-burning fireplace. The chimney/flue must be inspected and verified working (open damper during use). You'll also need a gas line run to the firebox if one isn't already there. Always have a licensed gas plumber install the line and have a hearth professional install and test the burner.
How do I light gas logs?
Most modern gas log sets use a millivolt valve with a wall switch or remote, or a match-light system where you ignite a pilot manually with a match. Check your specific set's manual. For first lighting after install, follow the manufacturer's burn-in procedure (typically 4–6 hours total of staged burns) to cure the logs and burner coatings before regular use.
Free shipping and warranty?
Free freight shipping on all orders, contiguous US. Most gas log sets carry a 5-year warranty on the burner and a limited lifetime warranty on the ceramic logs against defects (warranty terms vary by manufacturer — full details on each product page). 30-day return window on unused, uninstalled gas log sets.
