Ultra quiet operation < 70 DBA
Single Phase Power 115V - minimal electrical energy consumption
UL Listed (Natural Gas)
Controls are CSD-1 Compliant



Advenced Burner Technology

The ClearFire-V's high efficiency is achieved by employing an
advanced Fecralloy burner designedto premix air and fuel for
optimal combustion and low emissions. A varible speed blower motor
provides extended burner turndown capabilty


Patented Heat Tranfer Technology®

The internationally patented Alufer firetube is the latest Claver-Brooks
innovation in advanced heat transfer technology.
The tube is constructed from an inner aluminum alloy finned surface,
die fitted within an outer carbon steel tube providing exceptional
heat exchange characteristics that are attributed to the following factors:
Thermal conductivity of the Alufer insert is significantly greater than
that of carbon steel.
internal finned surface of the Alufer® tube enlarges the heat exchange
surface area threefold
Inner surface of the tube is divided into ten flow channels
to create maximum turbulence and heat transfer.
