This is an aftermarket blower replacement that replicates the UZY4 Blower for several models of BIS wood burning fireplaces. It is worth noting that BIS fireplaces has changed names several times over the years. BIS parts have also been referred to as Security, Lennox , IHP and Astria Fireplaces.
The blower helps circulate the warm air created by the fireplace around the room in a much more efficient manner, resulting in greater overall heat output. This after-market blower is much less money than the original OEM blower from Security, yet maintains a high performance.
This is just the blower replacement- it is not the full kit. Additionally, this is just a SINGLE blower- some of the older BIS models require two blowers. Order two if you need a full replacement.
OEM Part Number: HB-RB67 (UZY4)
Product Technical Details
12.9″ x 4.3″ x 3.6″
Blower wheel: 2.6 x 4.7
BIS OEM replacement parts have been somewhat difficult to access because of the age of the fireplaces . Also, these aftermarket BIS blowers are retrofit to be installed seamlessly within the existing fan mounts and have a higher CFM (will pump out more air) than the factory originals. Another added bonus is that these fans are much more quiet while in use.
These BIS Uzy4 Blowers are in stock and will ship within 1-2 business days
