BTU (British Thermal Unit) - 
Technically, the measurement used to calculate how much heat is required to raise the temperature of one pound of water by one degree Fahrenheit. This is the term used to describe the heating capacity of a fireplace, stove or log set in order to determine which heating appliance is best suited to the square-footage that requires heating.

Burn Rate - 
The number of pounds of fuel consumed in one hour of combustion.

 - Found in gas stoves and fireplaces, this is the pan or tubes that carry the gas used for combustion. The burner is found underneath the log set or, in contemporary style units, under the glass beads or stones that replace the traditional log set.

 - Also referred to as Natural Vent, a B-Vent fireplace or stove is a gas-fuelled unit that gets its combustion air from the home rather than the outside but vents exhaust from the combustion process to the outside. 


Cast Iron
 - The process of heating iron to a liquid form and pouring it into molds. All Vermont Castings cast iron products are made from recycled and reclaimed cast iron using environmentally friendly sand molds for casting. Vermont Castings cast iron stoves and fireplaces are all handcrafted and proudly made in Vermont, USA.

Direct Vent - 
Direct vent fireplaces, stoves and inserts eliminate the need for a traditional chimney. Direct Vent appliances draw combustion air from the outdoors as well as exhausting to the outdoors using a pipe venting system finished on the exterior with a vent cap. Direct Vent appliances are often vented up through the roof or out to the side or back of the building. Direct Vent units must have a sealed glass door to maintain proper combustion and to ensure efficiency and indoor air quality.


 - The percentage of heat that goes into the room instead of being vented to the outdoors.

Electronic Ignition
 - A burner ignition system that uses an electric current rather than a live spark.

 - The unburned smoke and gases that are left over after the combustion process is complete. Vermont Castings has 6 of the top 10 cleanest burning stoves in the industry.

Trim Kit
 - Decorative bars that are attached to the inside edge of a fireplace to complete the installation and add a stylish accent. Trim kits are available in numerous sizes and finishes to help create a look to match any décor.


 - Vent free or unvented fireplaces, stoves and inserts operate without an exterior venting system. Vent free appliances draw combustion air from inside the home and are designed to burn so efficiently (up to 99.9%) as to eliminate the need for venting. Currently vent free appliances can be installed in most areas of the United Sates. Please check with your local building official for approvals in your area.


Warming Shelves - 
Decorative and functional stove accessories that are attached to the sides of a stove. Each warming shelf contains two mitten racks that are used for warming clothing or other items on the stove.


Zero Clearance Fireplace
 - Zero clearance fireplaces are factory-built gas fireplaces that can be installed where there is no existing fireplace – generally on any inside wall that allows for the proper venting – and are tremendously popular for renovations and new home construction. In fact, adding a zero clearance fireplace to an existing home is a relatively inexpensive way to add value. The term zero clearance refers to that fact that they can be safely installed in direct contact with combustible floors and walls since they are manufactured using multiple layer construction with an inner and outer shell for maximum heat insulation. by JBS Retail - Copyright © 2024 All Rights Reserved
