Heater Exhaust Cap

In between downpours I managed to cut the hole for the heater intake/exhaust vent and to install the cap that comes with the heater. Ideally, it would be installed on a horizontal surface, but we should get satisfactory results out of this. Many people seem to be concerned about the proximity to the window. However, since the stove has to be hand lit every time we don't have to deal with a constant tiny stream of fumes sneaking in an open window.
I also discovered that the venting doesn't corner very quickly. This means the stove will need to be screwed to a box built several inches out the wall.
