Caring for Prefabs

Fireplace Pre Fab New Construction Firebox12How to Care for Prefabricated Fireplaces

The fireplace has certainly changed since its original design from so long ago. Improving fireplace parts is a constant project. Since the primitive use of fire containing devices, one of the most recent being the factory built or prefabricated fireplace unit. A prefabricated unit, or prefab, is made of metal instead of brick or other masonry materials. A prefab uses insulating pipes which are made by cooling air, and blowers to move the warm air around the house.

These systems are very sophisticated and manufactured and listed for use as a unit. Each part is approved by the Underwriters Laboratory to be used in a certain way under certain conditions with parts that make up the unit. A prefab doesn’t require a cement base for a foundation like a masonry unit due to how much lighter the prefab is. These systems have either cooling spaces in which air pockets act as insulation or actual insulation which allows the units to be closer to combustibles than would be otherwise.

Factory Built Prefabs

Prefabs reduce clearances and can sometimes be housed in wooden chimneys.

When factories build fireplaces, they generally last until a part needs to be replaced but is no longer manufactured. At this time the prefab unit will reach the end of its useful life. This is because it needs specific part in order to operate according to UL standards. The technician should install the stove according to the manufacturer’s instructions. It is not easy to remove in order to conduct an inspection





Safety Tips

Never install a wood stove into a prefabricated unit. You can operate a prefab according to the manufacturer’s instructions exactly. Similarly, it is not safe to burn paper waste in a prefabricated fireplace unit. This is because of how hot these fires get and how quickly they get so hot. (Since it’s close to the holidays, remember that it’s not safe to burn your Christmas tree in a prefab either. It produces a similar effect to a paper waste fire.) Also, when operating your prefab, the damper must be completely open. It should remain open until the fire is completely out. Prefabs require less clearance than other appliances. They’re easy to install in most areas of the home because they are so lightweight.
