This burner is certified for use in an existing fireplace with an open damper flue. Vented systems do not burn the gas used cleanly and therefore need to be exhausted through an open chimney - similar to burning wood. A vented burner can only be used in this application. It is not convertible to vent-free operation. A vented burner can be rated up to 75,000 BTUs to create taller flames but is still only rated as a decorative system and is not for use as a heat source and cannot be operated by a thermostat. A vented burner is only available in a manual model and a millivolt model. This is a manual model. The BTU input range is from 40000 (reduced*) - 65000.
The main advantage of a vented burner is the more realistic yellow flame created by the open flue. Unfortunately, to get the more realistic fire-look, the heat goes up the chimney as well.
If you are only looking for a decorative, non-heat source with more realistic fire then a Vented Burner is what you want in a gas log set.
Includes: Slope Glaze Burner, Embers, Lava Rock, Flex Line and Fittings.
