A good tech that deals with mobile homes, if that's what you installed it in,, did you replace the roof jack/also if it's a mobile home

What else besides roof jack

If the code reads you have ignition failure that is exactly what it means. Check and test the systems ignition. If it will not ignite then it will not burn. Contact the HVAC contractor that installed your unit since it is new. Most if not all the time the manufacturer will not warranty parts for you they have to be ordered through a coleman dealer who is your contractor.

We cannot test your unit for you since you have to be there to do the testing. Sorry.

Back in the day,and not to long ago,I installed a closed combustion coleman gas furnace, I learned the hard way,I had the same problem the code was tell me ignition failure. Well I checked everything,well when I sat down and carefully read the install instructions, I realized there was one thing I didn`t do,so I went and got a new expandable roof jack installed it ,and it worked perfectly,, this is all I know about the subject,, not that this is going to fix yours,, but,but,but.
