8 PC 45 Corn/Pellet Stove
Avoiding Smoke and Odors
Negative Pressure and Electrical Power Failure:
To reduce the probability of back-drafting or burn back
in the appliance during power failure conditions, the
appliance must be able to draft naturally, without opera-
tion of the combustion blower. Negative pressure in the
house may resist this natural draft if not accounted for
during the pellet stove installation.
Heat rises in the house, and leaks out at upper levels.
This air must be replaced with cold air from outdoors,
which flows into lower levels of the house. Vents and
chimneys into basements and lower levels of the house
can become the conduit for air supply, and reverse under
these conditions.
hearth & home Technologies recommends the use
of outside air in all installations, especially lower
level and main floor locations.
Per national building codes, consideration must be
given to combustion air supply to all combustion appli-
ances. Failure to supply adequate combustion air for
all appliance demands may lead to backdrafting of this
and other appliances.
When the appliance is side-wall vented;
The air intake is best located on the same exterior
wall as the exhaust vent outlet, and located lower
on the wall than the exhaust vent outlet.
When the appliance is roof vented;
The air intake is best located on the exterior wall
oriented toward the prevailing wind direction, dur-
ing the heating season.
The outside air connection will supply all of the de-
mands of the appliance. However, consideration must
be given to the total house demand. House demand may
consume the air needed for the stove. It may be neces-
sary to add additional ventillation to the space in which
the appliance is located. Consult with your local HVAC
professional to determine the ventillation demands for
your house.
venting Configurations
To reduce the possibility of reverse drafting during a
power failure, Hearth & Home Technologies strongly
recommends:
● Installing the vent pipe with a minimum vertical rise
of five feet, preferably terminating above the roof line.
● Installing outside air with the intake located below
the exhaust termination.
To prevent soot damage to exterior walls of the house,
and to prevent re-entry of smoke, soot, or ash into the
house:
● Maintain specified clearances to windows, doors,
and other air inlets, including air conditioners.
● Vents should not be placed below ventillated sof-
fits. Whenever possible, run the venting above the roof
line.
● Avoid terminating the vent in an alcove location.
● Vents should not terminate under overhangs, decks
or onto covered porches.
● Maintain a minimum clearance of 12" from the vent
termination to the exterior wall. If you see deposits devel-
oping on the wall, you may need to extend this distance
to accomodate your installation conditions.
Optional battery back-up
Hearth & Home Technologies supplies an optional
battery back up system to operate the appliance dur-
ing a loss of electrical power. Whether you experience
frequent power failures or not, this back up system is
recommended.
hearth & home Technologies assumes no respon-
sibility for, nor does the warranty extend to, smoke
damage caused by reverse drafting of appliances
during a power failure condition.
