Orienting the heat exchanger element

[CapnCuervo]

Hi All, does anyone have any tips on how to properly orient my Northern Lights heat exchanger element when reinstalling? I assume it has to do with the vented opening in the cartridge. Is there a “clock position” I can use to get it right or some other technique? I imagine it’s the same on most models, but mine is a M773LW3.

Thanks!
Andy

(Answering my own question here). I found a video on YouTube from Northern Lights demonstrating how to service the heat exchanger, and it provided the answer. The larger openings on the heat exchanger element go down in the six-o’clock position. Apparently the newer ones have “top” inscribed on the top, but there are no visible markings on mine.

Thanx.
