5 key decisions for designing a Linear Gas Fireplace

Linear Gas Fireplaces have a wide 4′ to 16′ viewing area and normally are not very tall 18″ to 36″. Although, some of our clients want a taller viewing area of up to 48″.

There are five key decisions in designing your custom linear gas fireplace.

1. Linear Gas Fireplaces can be single, see through or multi sided, what fits your commercial building or home the best?

2. How big do you want your viewing area to be? Width and Height and Depth. Remember, this can easily change as we go through the design process with you. The majority of the designers and architects we work with design the linear to be 3-4x wider than tall, therefore an 8′ wide linear is 2′ tall. The rules are not steadfast, many of our 12′-16′ wide fireplaces are 2′-3′ tall.
3. Flame, How big of a flame are you looking to achieve and are you looking for heat? The flame height is variable, however the bigger the flame the more heat generated and the more BTU’s the fireplace will consume. We offer two types of burners:
Option 1: is a single line burner and the media does spread it out a little.
Option 2: is a pan style burner that more evenly distributes the flames.
Heat – If you are not looking to achieve any heat from the fireplace we design a heat relief duct to transfer it outside, you can then have the large flame without having to worry about the heat.
4. Media Selection.  Media is the material used to cover the base of the fireplace and the burner. There are 4 main media styles to choose from and they can be combined, for example the stones on top of glass, and they are:
-Recycled Glass
-Glass Crystal





Recycled Glass for Gas Fireplace
Recycled Glass – available in all colors and are irregular shaped designed for fire in 1/2″ to 3/4″ size


Brown Glass Crystals for Gas Fireplace


Glass Crystals are round and smooth. They are designed to be used with fire, the mirrored reflection from the fire and the radiant heat is great!

5. Glass/ Fronts – we offer three choices a. single pane of glass b. dual pane system with outside air traveling between the panes to keep the glass cooler or c. Open – no glass or front

There are a couple additional installation items
1. How are you going to vent your fireplace? – vertically through your roof, horizontally out the side wall or down in through the floor. All our linear fireplaces use class A insulated stainless steel flue.

2. Combustion Air – all our fireplaces with glass fronts use outside for combustion, this is typically brought in the floor from below the fireplace
3. The fireplace will require a gas line and some require electrical for the ignition of the pilot.
