With the cap off the drain tube could let air into the combustion
chamber and possibly allow dangerous fumes to came out. I doubt that
enough of either would flow to be an issue but I would not leave it off.
The drain pipe tends to get partially or even completely plugged over
the years, so just removing the cap may not let much water or gases
flow. After the cap is off you can push a wire up into the pipe to see
how blocked it is. Don't push anything in more than 12" . A bicycle
spoke may work well.
