4 Questions Answered
Q: What is the difference between UDAS/UDAP? by Ray from Washington on August 10, 2016
A: 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. by Chris, Product Expert
Q: We recently installed 2 model UDAP150 gas fired heaters. I am trying to set up our ISO 9001 maintenance schedule. I need to know the recommended maintenance that must be performed on these, what should be done and at what intervals. by John from New Jersey on December 18, 2015
A: Reznor recommends annual maintenance for their UDAS unit heaters. This should include cleaning, inspecting, and testing major components and safety devices for proper operation. Details can be found beginning page 28 of the installation manual. by Chris, Product Expert
Q: Can you supply this unit with a 2 stage gas valve? by Dennis from Washington on December 18, 2015
A: 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. by Chris, Product Expert
Q: How does the UDAS-45 differ from the UDAS-45-AA2? Both appear to be usable with propane.
by Russ from Colorado on December 18, 2015
A: 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. by Chris, Product Expert

The heater was exactly what I ordered. It arrived on time and was professionally delivered to the shop door and unloaded.

Best Deal Around
Ordered this one to replace a 15 year old TF60. It seems Reznor has moved production to Monterey, Mexico. There is a 2-3 week wait for them to ship parts. Maybe President Trump can talk them into moving back to Pennsylvania??
That aside, I am happy with this new unit. It runs more quietly and heats my 800 square foot shop up in about 20 to 30 minutes, depending on outside temp.
eComfort is great to deal with - I ordered the unit on Thurs. afternoon, it was delivered to South Jersey on Monday morning.

Super Service, Great Heater
The heater was a replacement for the same model which had rusted out due to being operated at too low return air temperature for extended periods. I bought the same heater because the installation would be easier. I found the heater easily with my first Google search and eComfort was the first result I viewed.
After shopping around I was back to eComfort because their overall price (free shipping) and service (shipped in two days) was the best value. My heater arrived as advertised, was easily installed by me and is working perfect. I now keep the space at 55 degrees to avoid future damage to the unit. The price I found here at eComfort was the best on the internet!

"So easy, see my review above. You showed up at the top of the google search, I viewed your site first, and after shopping around found you had the best price, free shipping, and would ship within two days.
I got the heater quicker even though I'm in OREGON than I could have from several places closer plus I saved money! I would absolutely recommend your business."
Thanks for giving us a chance. We appreciate doing business with you.

Great Warehouse Unit.
Easy to install and works nicely. A little noisier than expected, But I guess that is expected with a big fan.

Great Heaters, Great Price
I just purchased three more of these units, all three are 200,000 BTU, one unit is for a propane application so the conversion kit was ordered for that unit. All three are now installed and working beautifully. The 83% efficiency rating helps reduce the price of these units by 25% because they qualifying for an energy rebate from our utility provider. Quiet, nice finish, great product.

Great Heat, But Extra Noise!
Upon opening the package, I noticed a loose piece of sheet metal inside on the floor of the heat chamber. Upon investigation, this piece belonged vertically placed to possibly stabilize each of the heaters, by fastening with only one sheet metal screw to the top.
I was able to get it in place and fasten the screw from the top outside with a larger screw, since the design one was stripped. All is well except for the noise, that I believe comes from this lone piece of sheet metal fastened in only one place. Still have to investigate it further.

Not Great
Not great... wish I kept my 40 year old one... it worked a hell of a lot better.
Product Expert
Sarita,
I do apologize, it looks as if your installer might have given you the wrong size to purchase from our notes. It sounds like it's too large for the space that it's trying to heat.
This creates a short cycle on the system and can cause the starter and burners to go out. Did you ever receive the warranty sheet that was sent out?
