PVC damper
Specify a sealed combustion furnace or boiler, which will bring
outside air directly into the burner and exhaust flue gases (combustion
products) directly to the outside, without the need for a draft
hood or damper. Furnaces and boilers that are not sealed-combustion
units draw heated air into the unit for combustion and then send
that air up the chimney, wasting the energy that was used to heat
the air. Sealed-combustion units avoid that problem and also pose
no risk of introducing dangerous combustion gases into your house.
In furnaces that are not sealed-combustion units, backdrafting
of combustion gases can be a big problem.
Other Ventilation Concerns
Some fan-assisted, non-condensing furnaces and boilers, installed
between 1987 and 1993, may be vented horizontally through high-temperature
plastic vent pipe (not PVC pipe, which is safely used in condensing
furnaces). This type of venting has been recalled and should be
replaced by stainless steel vent pipe. If horizontal venting was
used, an additional draft-inducing fan may be needed near the
vent outlet to create adequate draft. Floor furnaces may have
special venting problems because their vent connector exits the
furnace close to the floor and may travel 10 to 30 feet before
reaching a chimney. Check to see if this type of venting or the
floor furnace itself needs replacement. If you smell gases, you
have a venting problem that could affect your health. Contact
your local utility or heating contractor to have this venting
problem repaired immediately.
