usually I would say look for the LED diagnostic code display on the furnace, which will give you a sense of what the problem may be and its cause. However, I haven't been able to find an owner's manual or installation manual, which would let me know if there is an LED display and what the codes mean. If you have one, refer to that.

Otherwise, it is hard to know what may be causing intermittent heating, or no heating, from a distance. It could be related to the thermostat or perhaps a safety feature is shutting off the heat or it could be a problem with the heat exchanger.

The best thing to do is call a certified HVAC tech and speak with them about the problem. It is more than likely you will have to call one even if you can find the LED display.

Sorry not to be of more help.

To keep legal happy, let me just say that I am not an HVAC contractor, and you should never even look at your furnace without having a qualified, liability accepting HVAC contractor present.  To keep sales happy, let me just say that you can find an HVAC contractor that's happy to take your money here: http://www.furnacecompare.com/perl/find_contractors.pl.
