Features
    The Reznor UDAS is the solution to a cold garage or warehouse. With its seperate combustion, it is the perfect unit heater for areas that have a lot of combustible materials such as saw dust. With a 50-60 degree temperature rise range, you can maintain the temperature you desire. Reznor is the world's oldest and largest manufacturer of gas unit heaters so you know you're getting a product you can trust.
  • Easy Installation
  • The UDAS can be hung by either 2 or 4 points using threaded rods. The low voltage terminal strip is located on the outside of the unit to be able to connect control wiring easy. There is a gas line nipple on the exterior panel for easy gas connection.
  • Low Profile Design
  • The compact design of the Reznor UDAS allows for more overhead clearance than your conventional unit heaters.
  • High Efficiency
  • The patented Tcore one piece burner assembly provides you the highest efficiency of any other unit heater in its class. The UDAS is power vented to force exhaust gases through the flue, resulting in a more efficient heater.
  • Extreme Durability
  • The corrosion resistant aluminized steel heat exchangers are titanium stabilized and are designed to provide extreme longevity.
  • Low Noise Operation
  • With its vibration/noise isolated fan and venter motors, the UDAS produces minimal sound.
  • Product Note
    A vent kit is required for installation of this product. Please select a vent kit from the "Recommended Accessories" tab before checkout. The image above may not reflect actual product features. The Reznor UDAS-75 comes with four horizontal louvers.

What is the difference between UDAS/UDAP?
Ray  
from Washington 
August 10, 2016
Answer
The UDAS model has a separated combustion which requires a second pipe for fresh air from the outside. The UDAP model is a standard combustion unit which only requires one pipe for the exhaust.

The UDAP model is fine for most applications, but if you have a space that is tightly sealed, or contains lots of air born contaminants and pollutants, the UDAS may be a better option.

Can you supply this unit with a 2 stage gas valve?
Dennis 
from Washington 
December 18, 2015
Answer
Sizes of the UDAS and UDAP heaters 60,000BTU/hr and up can be special ordered with a 2-stage gas valve. This version will need to be special ordered, so it will cost slightly more and also have a longer lead time. Please contact us for details and to learn about other available options.

How does the UDAS-45 differ from the UDAS-45-AA2? Both appear to be usable with propane.
Russ 
from Colorado 
December 18, 2015
Answer
The -AA2 model is a variation of a UDAS/UDAP unit heater that is set up at the factory for use with liquid propane. The standard UDAS/UDAP model is factory set for natural gas use. With the appropriate conversion kit, you can also adapt the base model for use with propane. Because the -AA2 models must be special ordered, it is usually faster and cheaper to order the standard natural gas model with the appropriate conversion kit, and adapt the unit for use with propane in the field. The appropriate conversion kit can be found listed under the 'Accessories' tab.
