Coleman DGAA056BDTB Getting really hot

[rythmo]

Hi,

I'm an HVAC tech but very limited experience with MH installs. Just installed this unit and the side panels were getting really hot, as well as the lower door. I cut power to the unit. It was getting late in the day and I will return in the am to check some things out. Thinking I will verify gas pressure is correct, it may be over fireing as well as inspect the exhaust and intake for obstructions though I don't expect to find any. Any other thoughts from more experienced people would be appreciated.

Thanks much
