Heating with Oil (continued)

There are reasons why a tee might not have been installed:

not physically possible due to space availability.
(Manufacturers have tried to address this issue by re-designing their tees to allow for easier installation.)

installer not aware of necessity.

Typically, homeowners are being given 90 days to comply before oil delivery is halted.

Direct-vent oil appliances

The photo above shows the outside termination of a direct-vented oil furnace. It is a good example of the type of problems associated with this type of venting:

	The termination is right under a window. Under certain wind conditions, toxic fumes can be drawn back into the house (probably the most common complaint with this type of vent).
	The unsightly black circle in the snow is oil soot. It is not uncommon for this type of oil vent to perform poorly, leading to excessive soot buildup. It will certainly kill any plant material in this area.
	Oil soot is very corrosive. It does not show up well in this photo, but the brick immediately above the vent is deteriorating. The vent termination is also corroding. We have installed an ICC Excel manufactured chimney in this home to replace the direct vent.

Incorrect Liner Material

The following photos show what can happen when aluminum is used to re-line a flue for an oil-burning appliance. (Stainless steel is required by code).

While the photo on the left is not very clear, you can see the top of what is left of the aluminum liner. It is down about two feet from the top. The white on the sides is frost.

The photo on the right show severe corrosion of the aluminum top plate, which is supposed to seal the top of the chimney and is part of the support for the flue liner.
