Description

Reznor's UDBS gas-fired, separated combustion unit heaters are available in 14 sizes ranging from 30,000 to 400,000 BTUH gas input.  Model UDBS heaters are designed for 82-83% thermal efficiency and are approved for commercial/industrial installations in the United States and Canada by the Canadian Standards Association (CSA).

Note: UDBS separated combustion units require installation of a specially designed combustion air/vent system including the unique concentric adapter box that allows for only one building penetration for both the vent and combustion air.
