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!
Stones and Black Glass in Gas Fireplace

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
Gas Fireplace with No Glass


This linear fireplace is open – no glass or front. The view is front and right side.
Listed above are the 5 main decisions required to complete the design of your custom linear gas fireplace
1. number of sides
2. viewing area
3. flame height
4. media
5. glass / fronts
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.

What is the difference between a fireplace and an insert?

Tuesday, November 1st, 2011

There is a lot of confusion about the difference between a fireplace and an insert. The actual definitions vary by region, I will explain the main differences between the two categories.

Category I – Fireplaces

A fireplace is a self operating system that is able to burn fuel. A fireplace will have its own chimney flue system. There are two main types of fireplaces:

1. Factory built fireplace – Acucraft manufactures factory built fireplaces that are pre – engineered systems where the chimney system and combustion air inlets along with controls for both are incorporated. The factory built fireplace is set in the home and built around with framing and stone.

Installed Fireplace

The fireplace installed above  is the completed factory built fireplace. This fireplace has the rustic arched doors with grids.

2. Open hearth fireplace – Open hearth fireplaces are typically built on site by a mason. The firebox is lined with real firebrick. Open Hearth Fireplaces provide alot of ambiance, however, the efficiency is appx -35%. The average open hearth uses very little outside air combustion and appx 300 cubic feet of air per minute is pulled from your home and goes up the chimney flue. Please note: all Acucraft wood burning fireplaces can be operated as an open hearth by simply removing the doors or burning with the doors open, providing your home has adequate make up air.

Open Hearth Fireplace – They will provide some heat for the area around the fireplace, however they are very inefficient and alot of the heated air in your home will go up the flue. Turn up the furnace prior to starting a fire.

Category II – Inserts

Inserts are units that are designed to fit inside an existing fireplace. They are most popular inside the open hearth fireplace because they can help the system burn more efficiently. Custom inserts are very expensive and difficult to design. Many Inserts require a lot of steel around the insert, called flashing, to close off the area between the little insert and the fireplace opening.

Acucraft does not manufacture Fireplace Inserts. Because we design our fireplaces to create more heat than any of our competitors, a traditional flue system will not handle the heat output our fireplaces create. We require a Class A Flue system with our fireplaces to ensure safety.

We hope this post helped explain the difference between a fireplace and an insert. As always, if you have any questions please call us to further identify the perfect solution for your needs. 763.263.3156 and ask to speak with a selection specialist.
