Glossary of Terms
Bellows - a popular accessory to help boost combustion in wood fires, feeding air
to the flames as it is forced out of an expandable bladder. Though unnecessary for
a gas hearth where the combustion level is easily controlled with the turn of a knob,
bellows' lovely finish in attractive blends of fine woods with vinyl or leather makes
them a decorative accessory.
BTUs - British Thermal Unit, the primary heat measurement
unit used by the hearth industry. It is the amount of energy required to raise the
temperature of 1 lb. of water by 1 degree F.
Catalytic Combustor - a device used on
some wood stoves to increase combustion efficiency by lowering flue gas ignition
temperatures.
Clearance - the distance required by manufacturers and building codes
between stove, connector pipe or chimney and any combustible materials.
Creosote –
deposits of condensed wood smoke in the chimney and connector pipe resulting from
incomplete combustion. It can ignite and cause a chimney fire.
Direct Vent – an appliance
with a sealed, specifically designed venting system, that draws combustion air from
outdoors and exhausts its 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.
Emissions – unburned gases and
particles as a result of incomplete combustion.
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.
Firebacks - protect fireplace
masonry and mortar, shielding them from extreme heat of the flames. Cast-iron firebacks
store heat from the fire and radiate it into the room after the fire has died down.
Firebacks work just as well in a modern gas fireplace as they do in a traditional
wood burning one.
Fireplace Inserts - heating units that retrofit into an existing
fireplace (masonry or factory-built). They burn wood, gas or wood pellets and offer
superior efficiency.
Flue – the passageway in a chimney for conveying gases to the
outdoors.
Freestanding Stove - a heating appliance normally on legs or a pedestal.
Gas
Logs – an open flame appliance with ceramic or ceramic fiber logs placed over a burner
to provide dramatic realism of a traditional flame. Manufactured log sets have a
burner that uses either natural gas or propane.
Glass Doors – doors attached to a
fireplace to close off the opening of the hearth from the home to prevent heat from
escaping up the chimney and prevent cold air from entering the home when the fireplace
is not being used.
Grate – a metal frame used to hold and contain burning fuel in
a fireplace.
Hearth - traditionally refers to the floor of a fireplace on which a
blaze is built. Today it is also used to refer to all the devices and equipment used
in connection with the fireplace and the stove industry.
Heat Shield - a noncombustible
protector used around appliances, smoke pipes or chimneys to protect combustibles
from heat sources.
Hopper - a container attached to an appliance in which fuel, either
coal, nuggets or wood pellets, is stored and from which the fuel is fed to the burner.
Island
Fireplace - a fireplace that has four sides of glass, for viewing from any angle.
Kindling
- thin, dry wood used to start a fire.
Liquid Propane - liquefied petroleum gas, available
in cylinders, for home use.
Mantle - an ornamental facing surrounding the fireplace
or simply a shelf above a fireplace.
Metal Liner - used primarily with fireplace inserts
and placed inside an existing chimney (usually masonry) to reduce the diameter of
the flue for more rapid exit of smoke and combustion gases. Also used when an existing
chimney is unlimited or deteriorating.
Natural draft (B-vent) Appliances - a gas-burning
appliance that takes in combustion air from the home and vents byproducts of combustion
outside the home.
Natural Gas - clean-burning fossil fuel transported to homes via
an extensive pipeline network.
Pellets - are made of 100% compressed wood sawdust
with no additives. A renewable fuel source made from sawdust or wood chips otherwise
destined for landfills.
Peninsula Fireplace - a fireplace that has three sides of
glass.
Seasoned - refers to cordwood that has been allowed to dry before burning.
Seasoning generally takes six to 12 months. Wood burns much more efficiently when
its moisture content has been reduced.
Unvented or Vent-Free Appliance - an appliance
that draws combustion air from inside the home. The appliance is designed to burn
so efficiently that it eliminates the need for venting.
Zero-Clearance Fireplace -
a factory-built fireplace that is constructed so that it can be placed, safely, with
close clearances to combustible materials.
