power vent appliance flue condensation

Guys-
are there any general rules for avoiding flue gas condensation on pvc piped power vent appliances?
-
I was walking the dog, and i heard some water bubbling from down the block. A neighbor has some type of power vent appliance, and the flue was completely filled with trapped condensate and it sounded pretty loud. (akin to my bong days back in college) I knocked on his door to let him know, but it got me thinking about my direct power vented water heater. Mine leaves the building envelope and goes 7 feet high outside because its above a walkway. Should the piping be insulated? and/or should I have a condensate drain inside? There is definitely a possibility of it being trapped, and there's not much info about condensate in the install manual.

How long have you
had the water heater? If it is fairly old and you have not had a problem then leave it alone. The water heater is not designed to be a condensing system although on cold start there will be some condensing inside the burner area which subsides once the heater heats up.
If there was no requirement for your heater to have any condensate provision then you are all set.0
