Empire 40" Loft Small Direct-Vent Gas Fireplace Insert (20,000 BTU)

OVERVIEW A Direct-Vent system uses two vent pipes. One draws air in from outdoors to support combustion. The other exhausts the by-products of combustion to the outside. The two vent pipes may be concentric (exhaust pipe within a larger diameter intake pipe) or co-linear (separate pipes of about the same size). Combustion takes place inside a sealed chamber – with a glass front in the 
case of a fireplace. Room air circulates around the combustion chamber, often assisted by a blower, to heat the room. A DV system is often installed along an outside wall to simplify the vent run, 
but can also be installed elsewhere in the home and vented through the roof. Advantages Good efficiency – 60 to 80% Good heat output with thermal transfer through the glass and air circulation Separates room air from combustion air May be used as primary heat source Can operate with a remote or thermostat Most systems can provide life-saving heat during a winter power outage Loft Direct-Vent Inserts A Di
