Snow
In regions with snowfall, snow might build up and freeze between the
heat exchanger and the external plate. This might decrease the
operating efficiency. To prevent this:
1 Remove the knockout hole (a) by tapping on the attachment
points with a flat head screwdriver and a hammer.

2 Remove the burrs, and paint the edges and areas around the
edges using repair paint to prevent rusting.
