The unit is not a boiler or furnace, it is a "space" heater. See lower right corner of picture.

If the MFG requires a flue vent it is to close to the door and it appears to be a dryer vent did it have the flapper in it also????????

The direct vent in your diagram would be for natgas or propane, would it not?

What would be the US/Mass. requirements for a direct vent oil outlet. Up here in Canada, it's 6 feet (all directions) from any opening window or door plus about 9-10 other provisions for distance from property line, inside corners, driveways/walkways, decks/porches, height above any horizontal surfaces, etc.

Hi Charlie,

Actually, the "dryer" vent housing is a 2 way housing at both sides of the wall. The current owner uses it as his access for his extension cord to the panelbox for his generator.
