PLEASE READ AND UNDERSTAND THESE INSTRUCTIONS
BEFORE BEGINNING YOUR INSTALLATION
Questions To Ask Local Building Official
A correct installation is critical and imperative for reducing fire hazards and
perilous conditions that can arise when wood pellet burning appliances
are improperly installed. The installer must follow all of the manufactur-
ers’ instructions.

NOTE: DIAGRAMS & ILLUSTRATIONS ARE NOT TO SCALE

CAUTION
The body of these appliances are very heavy. The
use of a heavy duty escalara (stair step hand truck)
is recommended for lifting the appliance body.
WARNING
Electrical grounding instructions: This appliance is
equipped with a three-prong (grounding) plug for
your protection against shock hazard and should
be plugged directly into a properly grounded three-
prong receptacle. Do not cut or remove the ground-
ing prong from this plug. Do not route power cord
under or in front of appliance.
Surge Protectors
A surge protector is recommended to ensure the stove’s electrical com-
ponents are not damaged due to a surge in the electrical supply. Only
highqualityprotectorslistedtoUL1449shouldbeused-lowquality
protectors do not provide the protection needed.
Smoke Detectors
Since there are always several potential sources of fire in any home, we
recommend installing smoke detectors. If possible, install the smoke
detector in a hallway adjacent to the room (to reduce the possibility of
occasional false activation from the heat produced by these appliances).
If your local code requires a smoke detector be installed within the same
room, you must follow the requirements of your local code. Check with
your local building department for requirements in your area.
Installation / Maintenance Standards
National Fire Protection Association – The primary NFPA standard that
refers to installation and maintenance of pellet appliances and venting
is NFPA 211 – Latest Edition: Chimneys, Fireplaces, Vents, and Solid
Fuel appliances.
This appliance requires noncombustible floor protection (the hearth pad
or alternate floor protection material does not require a thermal rating).
A noncombustible floor protector must fully cover the area beneath the
appliance as illustrated in Figure 1.
If the floor protection is to be stone, tile, brick, etc., it must be mortared
or grouted to form a continuous noncombustible surface. In Canada, if a
chimney connector / venting extends horizontally over thefloor, protection
must also cover the floor under the connector / venting and at least 2”
(51 mm) to either side (recommended but not required in the US). See
ClearancesandHearthProtectionshowninFigure 1.
The design of your home and where you place your stove will determine
its value as a source of heat. This type of appliance depends primarily on
air circulation (convection) to disperse its heat, and therefore, a central
location is often best. There are other practical considerations, which
must be considered before a final selection of locations is made. Some
of which includes:
SELECTING A LOCATION
FLOOR PROTECTION
NEGATIVE PRESSURE WARNING
This appliance is not designed to be operated in a negative pressure envi-
ronment. In very airtight homes with large kitchen exhaust fans, furnace
cold air returns, fresh air exchange systems and any other air system in
close proximity to the heating appliance may create a negative pressure
in the same room as the heating appliance. This can create dangerous
condition, drawing combustion by-products into the home. Be sure your
home has adequate makeup air to eliminate negative pressures caused
by the above-mentioned sources. Outside air connected to the appliance
probably will not resolve such a problem as the stove is not the source
of negative pressure. IHP accepts no liability for damages resulting from
negative pressures described here.
VentilationRequirements- Provide adequateair for combustion. The fresh
air requirements of this appliance must be met within the space where it
will be installed. Ventilation is essential when using a solid-fuel-burning
heater. In well insulated and weather tight homes, it may inhibit the rate
the exhaust flows through the venting system (caused by a shortage of
air in the home). The lack of air is caused by many common household
appliances which exhaust air from the home (such as a furnace, heat
pump, air conditioner, clothes dryer, exhaust fans, fireplaces, and other
fuel burning appliances). Also, the combustion process of this heater
uses oxygen from inside the dwelling. If the available fresh air delivery
in the dwelling is insufficient to support the demands of these appli-
ances, problems can result (i.e. excessive negative pressure will result
in performance problems. To correct this problem it may help to open
a window (preferably on the windward side of the house) or install an
outside combustion air duct to the appliance.

Damper Location and Adjustment
The damper is a plate that helps control the amount of airflow supplied
for combustion. With the damper pulled out all the way, the airflow is
at its maximum. As the damper is pushed in, the amount of air that is
allowed to flow is reduced.
It is very important to preset your damper prior to burning your pellet
stove. The damper rod is located on the right side of the stove as shown in
Figure 7. The damper should be pulled all the way out to the full open
position during initial operation. It may need to be manually adjusted
inward depending on the type of pellet fuel being burned. Adjustin1/4”
increments until optimum combustion air flow is achieved. The damper
control adjusts the amount of combustion air to the UltraGrate™. When
the damper has been correctly adjusted, you will observe a brisk, yellow-
to-whitish flame. Fuel should not “pile-up” in the grate. The proper air
settings will vary from stove to stove due to installation, altitude, and
the fuel being burned.

soot at the top of the flame, the damper will need to be adjusted to deliver
more combustion air (see Figure 7). If the flame is “short” at the higher
burn rates and appears to burn the pellets out of the UltraGrate™ faster
than they can be resupplied, or there are significant variations of flame
height within a single burn setting, the damper may need to be adjusted
to deliver less combustion air.
After the damper is adjusted, re-evaluate the appearance of the flame. It
may be necessary to continue adjusting the damper in increments until
proper combustion is achieved (the flame should become a brighter
yellow and begin to “dance”).
Once the damper has been properly set, and if the routine maintenance
is performed as needed, the damper should not require re-adjustment
unless you are changing from a premium grade pellet to a standard or
high ash pellet, in which case the damper may need to be moved outward
to help prevent the accumulation of ash or clinkers in the UltraGrate™.
Damper Adjustment Guideline
Lack of Combustion Air: By opening the damper, this will increase com-
bustion air delivery. Symptoms of insufficient combustion air include;
unburned fuel, lazy smoky or red / orange flame, excessive ash or soot,
excessive buildup on glass, fuel may “pile-up.“
Contributing factors:
• HighAltitude–Lackofoxygen
• Restrictive Venting (elbows, horizontal runs, cold external
chimneys, etc.).
• Dirty/PoorQualityFuel.
• LackofMaintenance
NOTE: Excessive amounts of Fly-ash built-up in the grate, clinkers
in the grate or leakage of air (if the grate is not properly seated) will
starve the fire for air. See Routine Maintenance, on Pages 20 through
24 for information on cleaning requirements.
Excessive Combustion Air: Adjusting the damper to a more closed posi-
tion will reduce the combustion air delivery. Symptoms of excessive air
include; fuel burns too quickly (results in smoking or smoldering pellets),
white to yellow flame, etc. If the damper is open too far, the burning pellets
will lift off the grate and fly up into the air much like popping corn does.
Another flame characteristic of a damper that is open too far is a flame
that has significant variation in height on any single burn setting.
NOTE: Excessive combustion air reduces efficiency.
Contributing factor:
•· Ventingsystemprovidingexcessivedraft.
• Dry,hotburningfuel
CorrectCombustion Air /Proper Burn Characteristics:When the damper
is correctly set, the burning pellets should move (wiggle) around slightly
and the flame should be bright yellow.
Outside Air Installations
Connecting the Cascade™ pellet stove to outside combustion air is
optional, except in manufactured (mobile) home installations and when
requiredbylocalbuildingcodes.Thestove’sairintakewillaccept1-5/8”

It is recommended that only an IHP dealer install your pellet stove. The
specified installation requirements must be followed to ensure conformity
with both the safety listing of the appliance and local building codes. All
clearances, installation instructions and precautions specified by the vent
manufacturer must be followed.
Selecting a Location
Review the appliance clearance requirements before installing the
venting system (see Page 5). Position the appliance far enough away
from walls to allow adequate room for servicing. Choose the appliance
location with the least amount of interference with the house framing,
plumbing, wiring, etc.
Preferred Vent Configuration
For the best performance, we recommend a vent run design which runs
vertically and terminates above the roof line. This design will allow natural
draft to improve the flow of flue gases and will aid in combustion and
stove performance.
Type of Pipe
This stove is approved for venting with Type L and Type PL pellet vent
pipe(sometimesreferredtoas“L-Ventpelletvent”,listedtoUL641or
ULCS609).Connect the pellet vent pipe or the “tee” to the flue collar
using a minimum of three screws and seal as specified in “Pipe/Liner
Joint Requirements” on this page. Do not use class B gas chimney or
single wall chimney as a substitute.
Size of Pipe
These pellet appliances are approved for use with the following vent sizes:
3”(75mm)standard,or4”(100mm),seePage 13 - for determining

“tee” - available from vent manufacturer.
Offsets
In every installation, a single or double clean-out “tee” is recommended
for every ninety-degree offset (this tee will help collect ash residue and
will allow for routine cleaning without the need to disconnect sections
of pipe).
Pipe Clearances/Requirements
See pipe manufacturers instructions forinstallation of venting components
and clearances. Follow pipe manufacturers installation precautions for
passing pipe through a combustible wall or ceiling (i.e. use an approved
thimble).
NOTES:

the exhaust flow and performance of the stove.

Pipe/Liner Joint Requirements
Silicone sealant and three screws are required to secure the first vent
connection to the appliance flue collar. Secure the remaining vent sec-
tions using (3) three screws minimum per section, unless otherwise
specified by vent manufacturer's instructions. ALL horizontal joints
must be sealed gas-tight (air tight, sealed connection). Use RTV high
temperature silicone or Interam, if necessary, to provide a complete seal
between vent sections.
Connection to Masonry Chimney through a Wall
Be sure to verify the construction of a masonry chimney, as it may have
combustible framing.
Approved liner when relining Masonry or Factory Built Fireplaces is
2100HT(degreeF.)linerlistedtoUL1777orULCS635.
Connection to an Existing Class A Chimney

existing UL chimney system. Verify with the pipe manufacturer that your
pipe brands will interconnect.
Horizontal Vent Installations
On all horizontal vent installations (short, horizontal runs with no vertical
pipe); care should be taken when choosing a location for terminating the
vent. It is not recommended to directly vent the exhaust on the prevailing
wind side of the house. It is recommended that when an appliance is
venteddirectlythroughawall,aminimumof8feet(2.5m)ofvertical
pipe should be installed to create some natural draft. This will reduce
the possibility of smoke or odor entering the dwelling during appliance
shutdown or loss of power.
Vent Termination
Do not terminate vent in an enclosed or semi-enclosed area such as:
carports, garage, attic, crawl space, under a deck, porch, narrow walkway,
closely fenced area, or any location that can build up a concentration of
fumes such as a stairwell, covered breezeway etc.
Vent surfaces can get hot enough to cause burns if touched. Adults
should supervise children when they are in the area of a hot stove.
Non-combustible shielding or guards may be required.
Termination Cap
The termination of the outside chimney of the pellet stove shall be located
in accordance with the following:
A.Higherthan3feet(.92m)aboveanyforcedairinlet(airconditioner,
etc.) located within 10 feet (3 m).
B.Notlessthan4feet(1.2m)below,4feet(1.2m)horizontallyfromor

flue gases could reenter the dwelling.
C.Notlessthan2feet(.6m)fromcombustiblematerialssuchasan
adjacent buildings, fences, protruding parts of the structure, roof
overhang, plants and shrubs, etc. and not less than 7 feet (2.1 m)
above grade when located adjacent to the public sidewalks (access).
The final termination of the exhaust system must be configured so that
flue gases do not jeopardize the safety of people passing by, overheat
combustible portions of nearby structures or enter the dwelling.
D. The distance from the bottom of termination to grade is 12” (305 mm)
minimum unless otherwise specified by the vent manufacturer. This
is conditional upon plants and nature of grade surface: Be careful to
choose a location for the vent termination which does not expose
people or shrubs to high heat from the exhaust gases. The exhaust
gases are not hot enough to ignite grass, plants and shrubs located
in the vicinity of the termination although they should be a minimum
of3feet(.92m)away.Thegradesurfaceundertheterminationmust
not be a lawn.
E. Since sparks may escape from the exhaust pipe of any stove, use
caution when positioning the vent pipe. Refer to vent Manufacturer’s
instructions when installing and terminating the exhaust. The vent pipe
should be horizontal and never run the pipe in a downward direction
(recommenda1/4”[7mm]riseperfoothorizontal).

Standard Horizontal Vent Installation
Installing the Cascade™ Pellet Stove
This stove is approved for venting with Type L and Type PL pellet vent
pipe listed to UL 641 or ULC S609.
1. Locate the proper position for the listed type “PL” wall thimble. Avoid
cutting wall studs when installing your pipe. Use a saber saw or keyhole
saw to cut the proper diameter hole through the wall to accommodate
the wall thimble. Use extreme caution to avoid cutting into power lines
within the wall of the home. The hole size will depend on the brand
of pellet vent that you are using. Install the wall thimble in the hole.
2. ALL INTERLOCKING PIPE CONNECTIONS MUST BE SEALED GAS-
TIGHT AND SECURED TOGETHER PER VENT MANUFACTURER
INSTRUCTIONS.
Position the stove approximately 12” (305 mm) from the wall on the
floor pad. Push the “PL” pipe through the wall thimble. Squeeze a
bead of high temperature silicone (RTV) sealer around the end of the
machinedportionofthe3”(76mm)pipeconnectoronthebackof
the stove. Firmly push on a section of “PL” pipe until inner pipe liner
pushes into the bead of RTV sealer.
3. Push the stove with pipe attached towards the wall (the pipe will go
through the wall thimble). Do not position the back of the stove closer
than 1” (25 mm) from the wall (see Clearances, Page 5).
4.Installlistedtype“PL”45degreeelbowwithrodentscreenorcapon

NOTE: DIAGRAMS & ILLUSTRATIONS ARE NOT TO SCALE
Fuel Specifications - Using the Ultragrate™ burn system, this appliance
has been designed to burn wood residue pellets only (with up to 2% ash
content). Agricultural pellets (i.e. corn, alfalfa etc.) are not permitted to
be burned in the stove. Dirty fuel will adversely affect the performance of
the stove. The pellet fuel should meet P.F.I. (Pellet Fuel Institute) standards
for standard grade or premium grade residential pellet fuel. If the pellet
fuel meets these standards, it will be printed on the bag. Any questions
regarding pellet fuel can be answered at the Pellet Fuels Institute (PFI),
www.pelletheat.org.
Pellet Feed/Pellet Size - The pellet feed system is designed to handle a
widerangeofpelletsizesuptoamaximumof5/16”diameter.Different
pellets may feed at considerably different rates. You may notice a differ-
ence in the burn if you change pellet fuel sizes. The longer the pellet, the
slower it will feed and vice versa. If the stove will not stay burning at the
minimum fuel feed setting, those particular pellets may not be feeding
fast enough. If this happens, reduce the amount of combustion air by
adjusting the damper. See Page 8 before adjusting the damper.
Clinkering - Silica (or sand) in the fuel, along with other impurities, can
cause clinkering. A clinker is a hard mass of silica formed in the burning
process. Clinkering is a function of the fuel, (not the stove), but adversely
affects the performance of the stove by blocking off the air passages in
the grate. Even P.F.I. approved pellet fuel may tend to clinker. A clinker
can be removed from the UltraGrate™ and placed in the ash pan with
the use of the grate scraper/ash pan tool furnished with your stove. See
Routine Maintenance (on Pages 20 through 24)for more information
on cleaning.

CAUTION
The use of unapproved, dirty, wet and / or high salt
content fuel will void the warranty!
Filling the Hopper
To fill the hopper when stove is off:
1. Lift the hopper lid to it's full opened position.
2. Fill the hopper with pellets.
3. Check to make sure there are no remaining pellets on top of the
hopper that may prevent the hopper lid from fully closing.
4. CloseHopperlid.
To fill the hopper when stove is in operation:
1. Repeatsteps1thru4above.
2. When finished, check the red Auger “On” Light on the control panel
to verify that the stove is still in normal heating mode. The Auger
“On” Light indicates when there is power to the auger motor. Under
normal operation, this light will blink on and off.
3. If the Auger “On” Light on the control panel is off, the hopper lid
has been open too long and unit has gone into shut-down mode. To
relight, follow lighting instructions on Page 17.
CAUTION: Failure to ensure pellets in the UltraGrate remain
burning after re-fueling may result in smoke escaping from
the unit.

Automatic Safety Features
Power Outage: During a power outage, the stove will shut down safely.
Itwillnotautomaticallyrestartwhenthepowerisrestored.However,a
momentary power interruption may not shut your stove down.
A small amount of smoke may leak from the top of the window glass,
the hopper and from the combustion air intake, if the stove is vented
horizontally with no vertical pipe. This will not persist for more than 3
to 5 minutes and will not be a safety hazard. It may set off your smoke
alarm. To re-light the stove, follow the normal procedure for starting
your stove.

Ash - The frequency of removal of the ash and maintenance performed
on the stove is directly proportional to the ash content of the fuel and the
operation duration of your pellet stove. Low ash fuel may allow longer
intervals between cleaning, however, a stove burning high ash fuel may
need to be cleaned as often as everyday.
Fuel Feed Rates - Different brands of pellets will feed at varying rates
due to their size and density (length and diameter). This may require a
slight adjustment in the damper control (see Page 8) or the fuel feed
trim to compensate (see Page 18).
NOTE: SeeFuelDeliveryRateonPage 18 for burn times.
PLEASE NOTE: IHP has no control over the manufacturing of pellet
fuel and will not be held responsible for poor stove performance or any
damage caused by poor quality pellet fuels.
Pellet Fuel Storage -
• Store your wood pellets in a dry place to prevent them from absorbing
excess moisture.
• Do Not store your wood pellets within the clearance zone of the
stove.
• Do Not store your wood pellets in a place that would block removal
of the ash pan or block access to refueling the hopper.
Wood pellets manufactured to the pellet fuels institute (P.F.I.) certification
standard are available in two grades, Standard and Premium. The primary
difference between the two is the ash content of the pellets.
The P.F.I. specification for standard grade and premium grade residential
and commercial pellet fuel is as follows:
• CHLORIDES (Salt): Less than 300 p.p.m. to avoid stove and vent

ROUTINE MAINTENANCE
IMPORTANT CAUTIONS:
• UNPLUG POWER CORD AND ENSURE APPLIANCE IS COLD
BEFORE PERFORMING ANY MAINTENANCE WORK.
• Some brands of pellets produce more ash and clinkers than
others. Therefore the frequency of performing the following
cleaningproceduresdependstoagreatdegreeonthequality
of the pellets burned.
• Not cleaning this unit will cause it to burn poorly and will
void your warranty for this appliance.
• When removing ash build-up, use an approved ash vacuum
only.A cleaning brush can be used to loosen any ash build-up
before vacuuming. DO NOT USE A STANDARD HOUSEHOLD
VACUUM OR “SHOP VAC” AS THE FILTERS WILL LEAK THE
FINE PARTICLES OF ASH INTO THE HOME.
NOTES:
•Cleaning schedule will vary depending on quality of pellets used.
Burning high ash pellets will require more frequent cleaning.

UltraGrate™(Burn Grate)
(Recommended Frequency of 1 – 2 days*)
Inspect the UltraGrate periodically so that the air holes don't clog with ash
or clinkers. The UltraGrate can easily be cleaned with the grate scraper
tool, or it can be removed. It is very important to monitor the ash build up
under the UltraGrate, as too much of ash will block combustion air from
entering the grate, causing pellets to pile-up in the grate. A clogged grate
will reduce the overall performance of the stove, cause dirty glass and
if not cleaned may lead to smoke escaping the stove. The ash build-up
under the grate is easily dumped into the ash pan by pulling out the ash
slides weekly (see AshSlidePlate,Figures 23 and 25).
