. Design, Installation & Location Considerations
Warning! Risk of Fire
Damaged parts could impair safe
operation. Do NOT install damaged, incomplete or substitute
components.
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, fire
officials or authorities having jurisdiction over restrictions,
installation inspection and permits.
Since pellet exhaust can contain ash, soot or sparks, you
must consider the location of:
• Windows
• Air Intakes
• Air Conditioner
• Overhang, soffits, porch roofs, adjacent walls
• Landscaping, vegetation
When locating vent and venting termination, vent above
roof line when possible.
NOTICE:
Locating the appliance in a location of
considerable air movement can cause intermittent smoke
spillage from appliance. Do not locate appliance near:
• Frequently open doors
• Central heat outlets or returns

B. Draft
Draft is the pressure difference needed to vent appliances
successfully. When an appliance is drafting successfully, all
combustion byproducts are exiting the home through the
chimney.
Considerations for successful draft include:
• Preventing negative pressure
• Location of appliance and chimney
To measure the draft or negative pressure on your appliance
use a magnahelic or a digital pressure gauge capable of
reading 0 - .25 inches of water column (W.C.).
The appliance should be running on high for at least 15
minutes for the test.
With the stove running on high you should have a negative
pressure equal to or greater than the number given in the
chart.
Figure 23.1
If you have a lower reading than you
find on the chart, your stove does not have adequate draft
to burn the fuel properly.
C. Negative Pressure
WARNING! Risk of Asphyxiation!
Negative pressure can
cause spillage of combustion fumes and soot.
Negative pressure results from the imbalance of air avail-
able for the appliance to operate properly. It can be stron
-
gest in lower levels of the house.
Causes include:
• Exhaust fans (kitchen, bath, etc.)
• Range hoods
• Combustion air requirements for furnaces, water heaters
and other combustion appliances
• Clothes dryers
•
Location of return-air vents to furnace or air conditioning
• Imbalances of the HVAC air handling system
• Upper level air leaks such as:
- Recessed lighting
- Attic hatch
- Duct leaks
NOTICE:
Hearth & Home Technologies assumes no
responsibility for the improper performance of the
chimney system caused by:
• Inadequate draft due to environmental conditions
• Downdrafts
• Tight sealing construction of the structure
• Mechanical exhausting devices

B. Draft (Cont’d)
Correct low draft or low vacuum problems by doing one of
the following:
• Thoroughly clean the exhaust path and venting. See
Maintenance Section
page 14
.
• Inspect for worn or broken gaskets. Repair any gaskets
suspected of leaking.
• Refer to Section 5 starting on
page 23
for recommen-
dations on locating your appliance and chimney and for
causes of and minimizing negative pressure
