A . Design, Installation & Location Considerations
WARNING! Risk of Fire Damaged parts could impair safe
operation.DoNOTinstalldamaged,incompleteorsubstitute
components.
1. Appliance Location
NOTICE: Check building codes prior to installation.
• Installation MUST comply with local, regional, state and
national codes and regulations.
• Consult insurance carrier, local building inspector, re
ofcials or authorities having jurisdiction over restrictions,
installation inspection and permits.
It is a good idea to plan your installation on paper, using exact
measurements for clearances and oor protection, before
actually beginning the installation. Location of the appliance
and chimney will affect performance.
Consideration must be given to:
• Safety, convenience, trafc ow
• Placement of the chimney and chimney connector and to
minimize the use of chimney offsets.
• Place the appliance where there will be a clear passage
for a Listed chimney through the ceiling and roof (vertical)
or through exterior wall (horizontal).
• Installing the required outside air kit will affect the location
of the vent termination.
When locating vent and venting termination, the ideal loca-
tion is to vent above roof line when possible. This minimizes
the affects of wind loading.
CAUTION! Ifburningshelledeldcorn,youmustuseap-
proved venting specically designed for corn to prevent
corrosion or degradation. Follow the instructions from the
venting manufacturer.
Since pellet exhaust can contain ash, soot or sparks, you
must consider the location of:
• Windows
• Air Intakes
• Air Conditioner
• Overhang, softs, porch roofs, adjacent walls
• Landscaping, vegetation
• Horizontal or vertical vent termination
2. Floor Support
The supporting oor under the appliance must be able
to handle the weight of the appliance, fuel load and the
weight of the chimney.
Ensure that your oor will suport these weights prior to in-
stallation. Add sufcient additional support to meet this
weight requirment prior to installation. The weight of the
appliance is 9 lbs.

E. Pre-Use Check List
1. Place the appliance in a location near the
nal installation area and follow the proce-
dures below:
2. Open the appliance and remove all the parts
and articles packed inside the Component
Pack.
Inspect all the parts and glass for shipping
damage. Contact your dealer if any irregulari-
ties are noticed.

All labels have been removed from the glass
door.
11. Plated surfaces have been wiped clean, if
applicable.
12. Wall Control Thermostat has been installed.
13. A power outlet is available nearby.
14. A good quality surge protectory is highly recom-
mended to protect the electronics.
B. Thermostat Wall Control Location
The thermostat wall control’s location will have some affect
on the appliance’s operation.
• Maximum wire length from appliance is 100 feet (0.8m)
continuous unspliced wire. Recommended 0 gauge wire,
solid copper .
• When located close to the appliance, it may require a
slightly higher temperature setting to keep the rest of the
house comfortable.
• When located in an adjacent room or on a different oor
level, you will notice higher temperatures near the appli-
ance.
CAUTION! The wall control is an integral part of the appli-
ance. No other wall control or thermostat can be substi-
tuted.
D. Inspect Appliance and Components
WARNING! Risk of Fire! Damaged parts could impair safe
operation. DoNOTinstall damaged,incomplete orsubstitute
components.
• Open the appliance and remove all the parts and articles

NOTICE:
Termination must exhaust above air inlet elevation.
• It is recommended that at least 60 inches (1.5m) of vertical
pipe be installed when appliance is vented directly through a
wall. This will create a natural draft, which will help prevent
the possibility of smoke or odor venting into the home during
a power outage.
• It will also keep exhaust from causing a nuisance or hazard
by exposing people or shrubs to high temperatures.
• The safest and preferred venting method is to extend the
vent vertically through the roof or above the roof.

NOTICE:
Do NOT Terminate Vent:
• In any location that will allow ue gases or soot from enter-
ing or staining the building
• In any location which could create a nuisance or hazard
• In any enclosed or semi-enclosed area such as a carport,
garage, attic, crawl space, under a sun deck or porch,
narrow walkway
• Closely fenced area, or any location that can build up
a concentration of fumes such as a stairwell, covered
breezeway, etc.

B. Avoiding Smoke and Odors
Negative Pressure, Shut-Down and Electrical Power
Failure
To reduce the probability of back-drafting or burn-back in
the pellet appliance during power failure or shut down con-
ditions, it must be able to draft naturally without exhaust
blower operation.
Negative pressure in the house will resist this natural draft
if not accounted for in the pellet appliance installation.
Heat rises in the house and leaks out at upper levels. This
air must be replaced with cold air from outdoors which
ows 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.
Outside Air
An outside air kit is recommended in all installations. The
Outside Air Kit must be ordered seperately.
Per national building codes, consideration must be given
to combustion air supply to all combustion appliances.
Failure to supply adequate combustion air for all appli-
ance demands may lead to backdrafting of those and other
appliances.
When the appliance is roof vented (strongly recommended):
The air intake is best located on the exterior wall ori-
ented towards the prevailing wind direction during the
heating season.
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.
The outside air supply kit can supply most of the demands
of the pellet appliance, but consideration must be given to
the total house demand.
House demand may consume the air needed for the appli-
ance. It may be necessary to add additional ventilation to
the space in which the pellet appliance is located.
Consult with your local HVAC professional to determine the
ventilation demands for your house.
Vent Congurations
To reduce probability of reverse drafting during shut-down
conditions Hearth & Home Technologies strongly recom-
mends:
• Installing the pellet vent with a minimum vertical run
of 5 feet (1.5m). Preferably terminating above the
roof line.
• Installing the outside air kit at least  feet (1.m)
below the vent termination.
To prevent soot damage to exterior walls of the house and
to prevent re-entry of soot or ash into the house:
• Maintain specied clearances to windows, doors and
air inlets, including air conditioners.
• Vents should not be placed below ventilated softs.
Run the vent above the roof.
• Avoid venting into alcove locations.
• Vents should not terminate under overhangs, decks
or onto covered porches.
• Maintain minimum clearance of 1 inches (05mm)
from the vent termination to the exterior wall. If you
see deposits developing on the wall, you may need
to extend this distance to accommodate your installa-
tion conditions.
CAUTION
• DO NOT CONNECT THIS UNIT TO A CHIMNEY FLUE
SERVICING ANOTHER APPLIANCE.
• DO NOT CONNECT TO ANY AIR DISTRIBUTION DUCT
OR SYSTEM.
Optional Battery Back-Up
Hearth & Home Technologies supplies an optional battery
back-up system that operates the appliance during power
failure conditions to prevent smoking. In shutdown mode,
the battery back-up will not prevent smoking. See Section
8 for details.
Hearth & Home Technologies assumes no responsibility for,
nor does the warranty extend to, smoke damage caused
by reverse drafting of pellet appliances under shut down or
power failure conditions.
