    I have to take a state hvac test tomorrow and was hopping that I could get some clarification on a few questions.

    Q: What is the primary cause of rust at the draft hood?
    A: to many 90’s or a blocked chimney?
    A: Back drafting is an answer that I also came up with but this I do not under stand isn’t the draft hood supposed to prevent this?

    Q: what is the acceptable temperature rise for gas or an oil furnace?
    A: I came up with several different ones but am betting on 45-70 degrees is this correct?

    Well thanks in advance I appreciate the help

    I will say

    A blocked chimney is primary cause of rust, and a 70 degree rise for a gas or oil furnace is ok. J.Lockard
