    I have a bunch a practical friends, and we help each other out. We sort of trade hours. I do what I like for them, such as machining and welding.

    Put a high efficiency unit when I built my own house 2 years ago. They do such a god job the exhaust gas is moist...but not really warm. Its common to see a giant glacier hanging from the side of the house.

    Good point, but everything installed around here is a combination with an air conditioner, so we've got the condensate to deal with anyway.

    Very nice. No one around here installs the high-efficiency machines, so I'm still doing everything with B venting.

    The last step was to install the bezel on the outside of the garage addition.

    The next step was to install the PVC piping and the newly fabricated Unistrut support.

    The next step was to fabricate a brace to support the PVC pipes. First I dipped the end of the Unistrut into a container of Hydrochloric acid (Muriatic acid from Home Depot). The acid does a nice job of removing the zinc so you don't generate fumes when you weld it. Next I welded the base to the Unistrut using a Lincoln 210 MP welder.

    4. Removing Zinc with acid
    5. Welding the base plate.

    Last weekend's project is to connect the make-up and exhaust PVC lines to my high efficiency furnace for my garage addition. The first step was to bend a piece of Aluminum to wrap a piece of 3/4" plywood. The wrapped plywood was installed in the Vinyl siding to give me a good mounting surface for the exhaust bezel.
