Are the things rusting black iron pipe? If so, first, that may not be the best thing for outside, and second, if it is allowed needs to be painted, or like any iron, will rust.

on 8/16/2010 i had a tankless rinnai water heater installed by my gas company and it seems that some of the pipe connections, in and outside of the house look like they are rusting. is this suppose to happen? should i have the gas company look at it.
thanks

The outside pipe looks like it's black with gray paint on it but rust is coming through. the inside rust looks like it's occurring at connection points (these connection don't look black) between pipes and on pipe thread.
Can you attach a picture, 800 pixels or less.?
What connections are rusting the water inlet and outlet or the gas connections? picture is worth a thousand words
here is a picture of connection inside my house. i'll get more up for you to check out
Is this in a humid location? maybe a little oil or paint will slow it down
