An automatic flue damper is an energy-saving device that closes off or restricts an appliance flue when the appliance is not operating and is in its “off” cycle. It traps residual heat in the heat exchanger after the burners shut off, and prevents the escape of conditioned air up the vent pipe.

Discharge, Loop and Air Gap

The dishwasher discharge hose should be connected to the waste tee or disposer inlet above the drain trap. It is recommended that the drain hose either be looped up and securely fastened to the underside of the counter, or be connected to an air gap.

Many roof problems are caused by issues with the framing and sheathing. In this section, we will focus on the defects that may be viewed from the exterior of the property. This is one of those cases where standing back and taking a good, hard look is better than getting "up close and personal" with the roof.

Chimney Flues

While the inspection of chimney flues is a highly specialized procedure, any obvious deficiencies in the flue should be noted. In particular, pay attention to flues that are damaged, collapsed, or show signs of previous chimney fires. Extra care must be taken when inspecting chimney systems that are being used to vent fossil-fuel appliances, such as boilers, furnaces, water heaters and manufactured fireplaces, as any deficiency in either the liner or the chimney structure could be a potential fire starter, or could allow carbon monoxide into the habitable space within the home. It is now required that any traditional flues being used as vents for these appliances be fitted with continuous metal flue liners to ensure that no noxious gases can find their way into the home.
