High Efficiency Gas Boiler Questions

I had a Triangle High eff. gas boiler installed a while back and it's working well. I have a couple of questions though ...

1 - The PVC vent pipe was run vertically up the old 'tin' flue pipe. It extends a few inches above the old flue cap. There is no elbow installed at the top of the pipe. I was wondering if an elbow should/can be installed to prevent anything from coming in the exhaust pipe.

2 - I have a kick space heater in the kitchen that is the only heat source in that room. It needs 140 degree water to start up. The boiler has an outside temp sensor. There are times when the boiler water is less than 140 due to the outside temp. That causes the kick space heater to not turn on. I disconnected the outside temp sensor so that the kick space heater will always work. Can/will this cause problems with the boiler ?
I think I saw something in the manual about a setting for the min. water temp of the boiler water. I'm thinking that if I raise the min. water temp a little above 140, I could re-hook the outside temp sensor. I'm sort of reluctant to play with any of the boiler settings if I don't have to.

1) If the manufacturers install info allows an elbow or tee then it can be used and is a good idea to keep birds from nesting in it. If they don't then no as it will cause the pressure switches to trip.

2) You should get PM preventative maintenance done yearly and I would ask the installer or one of his techs. Some companies are getting VERY specific about not honoring warranties if no maintenance is done. Read the fine print. It is worthwhile to protect your investment and for efficiency and NRG savings anyway.
