I installed a wood stove and the flue piping to the ceiling support. When I started to stack the chimney, I found out that the chimney would be going through the peak of the roof. Is this ok? Will it cause any problems? Is it within code to set it up this way or do I need to find another way to position it?

I am a relatively new homeowner. When we bought the house, we checked the gas fireplace, and it works. I am trying to start it now, and I can't seem to get it on. I have a wall switch, a gas on off valve, a pilot turn switch, and some sort of on/off button. Oh, and a starter The pilot tun valve has a red dot at the bottom of it, and i have to push the switch in to get it to turn to face that red dot. But then it is facing off. I am pushing the starter, and I see a little spark, but I can't get anything else to happen. I've never had a natural gas fireplace before, so I'm a bit lost. I'm hoping to get it on today before the fiancee gets home in several hours. Anyone have experience with this? EDIT: I got the whole system up and running, and a fire going. Can I just turn the wall switch on and off, or do I have to do other steps? Also, how do I clean the glass? I don't see an easy place to just remove it
