    roof avalanches

    Watch out for sliding snow. I have been making every effort to put roof penetrations high up near the peak so the big avalanche that WILL come down someday won't shear the vent off or fold it over.

    Vent seperation

    This drawing is from the manual which is printed in Germany (slight loss of translation occurs). We suggest you refer to the "Applications Manual" as that is printed here in the United States. In the Applications Manual it states the exhaust must be a minimum of 12" above the fresh air intake but no greater than 24". We are working on getting this straightened out.
    Don't believe this is creating the "hoar" frost issue. My hypothesis (guess) is that the GB142 burner has shut down due to very little delta T, but the circulator is still flowing water through the heat exchanger. The warm air in the housing on the GB142 is rising out the air intake pipe, condensing on the elbow, and then freezing.

    Have tried posting to this thread two or three time and couldn't - dont know why but trying again.
