BTUs British Thermal Unit, the primary heat measurement unit used by the hearth industry. It is the amount of heat required to raise the temperature of 1 lb. of water by 1 degree F.
B-Vent a gas-burning appliance that takes in combustion air from the home and vents products of combustion outside the home. B-Vent is also commonly known as Natural Vent.
Catalytic Combustor a device used on some wood burning stoves to reduce the temperature at which smoke is ignited.
Clearance the distance required by building and fire codes between stove, smoke pipe or chimney and combustible materials such as wood furniture or carpets. Clearances must be obeyed even if the combustible materials, such as wood furniture or carpets, are protected by noncombustible plaster or other masonry materials.
Direct Vent an appliance that draws combustion air from outdoors and exhausts it's combustion products to the outdoors eliminating the need for a standard chimney system. A glass panel in direct vent units is critical to keeping the combustion system sealed from the home, maintaining high efficiency and indoor air quality.
Electronic Ignition requires electricity to start the unit.
EPA Regulations government regulations of wood burning appliances mandating that products sold after July 1, 1992, emit no more than 4.1 grams of particulate matter per hour for catalytic-equipped units and no more than 7.5 grams for non-catalytic-equipped units.
Inserts heating units that retrofit into an existing fireplace (masonry or factory-built). They burn wood, gas or wood pellets and offer superior efficiency.
Manually Controlled control the height of the flame at the unit only.
Pellet Burning are made of 100% wood sawdust with no additives. The sawdust in pellets is a manufacturing byproduct otherwise destined for landfills.
Remote Ready able to turn the unit on and off remotely via a wired or wireless remote. Remote is sold separately. Cannot adjust the height of the flame remotely.
Not recommended for vented gas logs.
Thermostatically Controlled senses the temperature at the unit not of the room. Not as versatile as a remote ready with a thermostat.
Variable Flame Height via the remote can increase and decrease the height of the flame.
Vent-Free gas appliance that has no need for a flue. Units offer high efficiency but may not be permitted in some areas, please check with your local building official.
Zero Clearance Fireplace a factory-built fireplace that is constructed so that it can be placed, safely, close to combustible material.
