I don't know how you couldn't have a manometer, but I know a company that installs that dosen't, us and them gave a price to install a fireplace insert and o course they were lower. I was doing ductwork on the job on the day they happen to fire it and what do you know it isn't burning well and they wanted me to look at it because the other guy didn't have a manometer to test gas pressure. I wanted to say f you but the customer still owned us money. A simple check found the gas pressure very low. So know the guy is out putting furnaces in and other stuff, and of course can't be setting them up proper.
