REZNOR has over 35 years experience in designing
and refining high efficient gas-fired unit heaters.
The UESA is a condensing gas-fired unit heater and is
designed for up to 104% heat input (Hi).
The units are available in 4 different sizes, from 35 till
102 kW gas output.
Simplicity and ease of use
 Up to 25 % lighter than the previous model and easy to install.
 The unit can be easily suspended from 4 suspen-
sion points.
 All units have a factory installed gas line nipple to the exterior of the cabinet for easy gas service
connection.
 The MacroChannel secondary heat exchanger has a

 The internal security system protects the unit from overload and keeps the flue gas
temperature down in the flue gas circuit.
Main standard features
 The Tcore3TM high efficiency heat exchanger and
single burner combustion system.
 The titanium stabilized aluminized steel primary heat exchanger with extruded aluminium
MacroChannelSM secondary heat exchanger.
 The vibration and noise isolated fan motor.
 The sealed control compartment houses all electrical
components.

Guaranteed high efficiency
A conventional unit-heater does not use all available
combustion heat.
An important part of the heat is still present in the
exhausted flue gases.
The Reznor UESA is able to extract the residual heat by
leading the flue gases through a second heat
exchanger, so they cool down to a temperature below

BALANCED FLUE WALL AND
ROOF TERMINAL
OR
C-type: the allowed length between the unit heater and the flue terminal amounts to 9 m,
a 90° bend offering an equivalent resistance of 1,5m and a 45° bend -0,75m.
Advice: the high efficient balanced roof terminal avoids icicles.

1. Gas Appliance Classifications for Approved Venting Methods based on CEN-report CR1749:2001
2. Height from floor to bottom surface of heater. These are recommendations only. Positioning of unit heaters for proper performance is application dependent. Operation is affected by other air moving equipment in the space, obstructions to the airflow, draughts and/or close proximity to doors or windows, etc… Care should taken to avoid mounting the heaters above these recom-
mendations, unless downturn nozzle options are used, as significant stratification may occur resulting in poor floor coverage and higher energy losses through the roof structure.
