Overview
The intent of this manual is to provide information regarding safety, design guidelines, installation,
operation and maintenance of the UH Series gas-fired unit heater. You must read and understand the
instructions and all safety warnings before installing the gas-fired unit heater. This manual is property of

Heater Components
Prior to installation, verify that the heater’s gas type and voltage (as listed on the rating plate) match
that of your application. Also verify that you have received the entire heater contents included with your
unit. Refer to page 56 for a list of the kit contents for your heater. Materials not included with the unit
(e.g. screws, vent material, threaded rod, etc.) are the responsibility of the installer. Notify your product
representative or the factory of any discrepancy of missing items prior to installing the unit.
