600 sq ft Apt sized Gas heater suggestions

MultifamilyAptGuy

Greetings.  I have a dilemma for an apt unit of mine that has a gas fired console heater that heats the apartment made by Cozy.  Here is a manual on the product <a href="http://www.cozyheaters.com/pdfs/products/Vented-Console-Room-Heater.pdf">http://www.cozyheaters.com/pdfs/products/Vented-Console-Room-Heater.pdf</a>



I purchased this heater as a replacement to a 17 year old unit approximately 3 years ago.  For 3 years, it worked fine, but this year, whenever its turned on, the pilot flight floats past the assembly.  Pressure was checked (normal), pilot was cleaned, venting is good.  My repair guy could find nothing wrong with it.  Called the manufacturer, who claimed that the unit was installed wrong (overlooking the fact that it worked fine for 3 years).  Then they backtracked and said due to energy efficiency standards, they don't work as well as the old units.  Finally offered to replace the heat exchanger if I bend over backwards and wait 2-4 weeks to fill out all the paperwork.  Obviously can't do that.



So now I am in the search for a similar 30K BTU or so nat gas heating unit that is relatively inexpensive and an easy install.  Or will consider another great suggestion.  This is heat paid for by my tenants.

A 600 sq ft apartment should need far less than 30,000 BTU/hr.  When was the building built?  Where is it located?  What percentage of its wall area is exposed to outside air?  Sizing is important here.
