Excellent point Fred! I actually had a nightmare about this very thing. I really
need to get out more....

I used a pneumatic vacuum pump I got from Harbor Freight for about 10 bucks. Just
connect it to the vent line with a vacuum gage "T"ed in. Don't let the
differential pressure get above 1 PSI  !!!!! do the work outside with no sources
of combustion nearby.

Brent
