ThreePronged Plug (Grounded)
A grmmded electrical cord is supplied with this applicmcc.
The power cord should be connected to a standard I 15
volt A. C., 60 heriz electrical outlet (power requirements
are 240 watts). Be careful that the electiical cord in not
trapped under the appliance. Keep it clear of any hot
areas, and sharp edges.
Control Board
The control board is located on the left side panel of the
stove. It manages tl1e rate of combustion (combustion
fan), heat output (fuel delivery) and heat circulation (room
air fan).
Auger
Pellet fuel is fed to fue frrepot by means of an auger. 11us
auger is chiven by a high torque gear motor. The auger is
capable of doing seiious harm to fingers. Keep pellets in
hopper at all tinles and keep fingers away from auger.
The auger can start unexpectedly when the stove is
nummg.
Optional BrassDoor/Ash Tray/Legs
The brass should be cleaned thoroughly before fue stove
is
burned. Do not clean brass with an abrasive cleaner.
Apply the brass cleaner only when stoveis cold and clean
and wipe offany excess brass cleaner after use or the brass
may discolor. Any oils or fingerprints left on the brass
could become permanent blemishes if the stove is brnned
prior to their removal.
Firepot
The pellet Firepot is where the fuel is bW11ed. (see page
17 for cleaning requiremenL<;).
Hopper .
The Hopper is where the pellet fuel is loaded and stored
before the pellets are fed into fue firepot.
Ash Pan
1l1e Ash Pan located Wlder tl1e exteiior ash lip is designed
to mak~ cleatling easier by containing the ashes in a
removable pan. It is accessed by turning the screws
coWlter clockwise on tl1e ash pan door to release the
spring latches. Do not operate the stove unless the ash
pm1 door is sccw·cd. Replace ga<>kct material as necessary
to ensure a tight seal.
*Optional Remote Thermostat
One \Vay to ma'{imize the efficiency and converuence of
yom stove is to install a remote Thennostat. One
recommendation out of mat1y is aHoneywell model
T87F, 24 volt thennostat (see page 16).
*Optional Ceramic Log Set
Although the logs me quite durable, they should be
hat1dled carefully, as tl1ey retain heat for a considerable
period of
time, at1d ifdropped c.:111 break. Place the
ceratnic log set uptight atld as far forwat-d on the
secondaty air tube mat1ifold as possible. Be sure log set
does not interfere with flatne or cover firepot.
Glass
1l1e Glass is a super heat resistant ceramic that withstands
continuous temperatures
up to 1390°F. 111is temperature
is well beyond tl1e temperatmes in which you operate
your stove.
This appliance is designed to provide a flow of air over
the
inside of the glass, which along with high heat helps
keep it clean. When operating the stove on low for
extended peliods of time, the glass may get dirty. A
commercial glass cleat1er designed for stove glass is
recommended for cleaning.
1l1e glass should be cleat1ed fuoroughly witl1 glass cleat1er
and a soft cloth BEFORE the stove is burned.

INTRODUCTION (Continued)
HOW IT WORKS
The Control Board manages the rate of combustion (<.Iran fan), fuel delivery/heat output (auger gear
motor), and heat circulation (room air fan).
Draft Fan Operation )
The draft fan pulls air into the appliance by
extracting the exhaust out
of the firebox. This
creates a negative pressure.
It first enters through a
flexible hose to a plenum behind the fire chamber,
then through a tube to the back
of the firepot and
through the bottom and sides
of the firepot
combustor plate out into the fire area. Some air
also comes through the secondary air manifold.
During combustion the.super heated exhaust
rises
in the fire chamber. It is drawn out at the top of the
fire chamber through a penthouse box.
It then
moves downward through a channel behind the fire
chamber. The hot combustion air is drawn out by
the draft fan
and is then forced along through the
inner pipe of a double duct system and exits
through the flue at the top back
of the stove.
Though not shown, air is also forced across the
window (at the top and bottom
of the front door
opening) to inhibit the buildup
of soot. An optional
exhaust plate adapter allows the stove to be fitted
to
an existing 6" stove pipe chimney system, or 3 "
pellet vent pipe. A 4" outlet
is standard.

Room Air Fan Operation
Room air is drawn through the slot openings in each side panel by the room air fan and is forced through
the outer pipe
of the double duct system. The room air is pushed upwards at the back of the fire chamber
through it's own manifold
to the top of the stove. The air passes around the super heated penthouse box,
picking up more heat as it flows. Then the air is forced out
of the front of the stove through I0 holes.

INSTALLATION
Selecting a Location
The design of your home and where you place ymrr stove
will determine its value as a source of heat. Practical
considerations may be most important in selecting a
location:
Existing Chimneys
Room Traffic
Proximity
to combustibles
Aesthetic Considerations
Electrical Wiring
RoofDesign (rafter locations & roof pitch)
Do not install stove in abedroom
Once your options are determined, consult with your
local building official regarding any potential problems.
If you plan to vent your stove into any existing masonry
chimney, have it inspect by a local fire marshal or
qualified installer. A stoves performance is heavily
influenced by the chimney.
Suggestions: Locate this appliance in a large and open
room centrally located in the dwelling to optimize heat
circulation.
For optimwn perfom1a..nce the manufacturer
recommends a Top Vent installation with pellet vent
chimney pipe rw1 up through the eave as opposed to a
Direct Vent installation. A Direct Vent installation is
where the vent tenninates on an outside wall directly
behind the stove with no vertical pipe. In the event ofa
loss of power, when installed as aDirect Vent, natural
draft is not present and may allow smoke back into the
dwelling.
Assembly
TI1e Model PF-70 comes with apedestal, or four legs or
can
be iristalled as an insert. To assemble leg or pedestal
based units:
1. Remove metal pedestal (or legs) from the box.
2. Remove the box from the appliance.
3. Place the appliance on top of the pedestal (or support
the stove while you attach each leg).
4. Secure the stove and pedestal (or legs) by fastening
them to the bottom of the stove using the screws
supplied (4) 5/16-18x3/4" for pedestal, or (4) 1/2-13x
1 1/4" for legs.
Remove ash lip from box. Install below door opening to
the two (2) corresponding threaded holes in the stove
front, using the two (2) 5/16-18 x 3/4" socket (allen) head
screws provided. This will require the use of a size 1/4"
Allen wrench tool, not provided.

INSTALLATION
Pre-Installation Procedure
Note: Before unit is installed it is recommended
that it be pre-burned to verify the operation. This
will also allow
it to bum off sub-surface oils that
may be present, and
to help cure the paint. The
"Pre-Installation Procedure" should be done in a
well ventilated
ar~a as follows:
I. Plug the stove into a grounded outlet (using a
circuit tester, verify the electrical outlet for
proper ground and polarity
where the unit will
be installed. failure to do so could result in
damage to the electrical components and void
the warranty).
2. Switch on power by pressing OFF/ON switch
(lower rocker switch) upward to the "ON"
position. The LED (light emitting Diode) light
will come
on and glow red (early production
models
glow green). The Draft Fan will come
on.
3. Look down into the Hopper and make sure
nothing is obstructing the auger. Pour
114 bag
of pellets in the Hopper.
4. Set Feed
Rate Control Switch to low or
medium-low setting.
5. Press auger Jog/Start switch (upper rocker
switch)
downward to initiate 12 minute start
cycle. The
LED lamp will now appear orange
during this 12 minute period. This will bypass
the
low temperature limit disc (snap switch) and
allow the
auger to feed pellets to firepot at the
feed rate setting selected.
6.
Apply nonvolatile lighting material to the pellets
and light
it with a match. Let the fuel burn for
five minutes leaving the
door slightly ajar.
7.
If the stove has not warmed sufficiently after the
12 minutes (LED will revert back to red glow-
earlier models glow green) to keep auger
dropping pellets
(low limit thermostat will not
have reached set temperature to close contacts
and complete the auger circuit), merely repress
rocker
switch to restart 12 minute cycle.
During this
time the feed rate should become
automatic.
8. Pressing Auger/Initiate switch upward will
manually engage auger.
This can occur only
after start cycle is started
or stove is at operating
temperature. This would be used to more
quickly get the
auger to start pellets dropping
when hopper is refilled after running out
of
pellets.
8. Set Fuel rate switch to desired heat output by
turning the
knob clockwise. This will increase
the burn rate from low to
medium-low to
medium-high to high.
9. Once ru1ming, observe the stove operating for
15-30 minutes.
1
0. J\s the stove temperature rises, the Room J\ir
Fan will automatically be engaged.
11. Once the stove is operating properly, complete
filling the
Hopper and run the unit for 30
minutes.
Paint Cure-In Period
Your stove finish is a high temperature paint that
requires time and temperature for the silicon resin
in the paint to completely cure. Depending on your
use, this may take a few hours
or a few days. The
paint manufacturer recommends you ventilate the
house during the initial burns.
Although the
emission is primarily Carbon Dioxide, there are
other components emitted
which make it smell bad
and may irritate
some people. Do not place
anything on the stove surface until the paint is
completely cured, as it will
become soft during this
process.
Do not attempt to repaint the stove until
the paint is completely cured.
If the surface later
becomes stained
or marred, it may be lightly
sanded and touched
up with spray paint from the
same paint manufacturer:
Paint is available at your
local dealer.
KEEP YOUR HOUSE WELL VENTILATED.
DURING
THE CURING PROCESS. THE
CHEMICAL SMELL AND BLUISH HAZE
EMITTED
BY THE CUIUNG PAINT CAN BE
QUITE NOTICEABLE AND MAY SET OFF A
SMOKE DETECTOR.

INSTALLATION
Vent Termination Requirements
Do not terminate vent in an enclosed or
semi-enclosed area such as: carports, garage, attic,
crawl space, under a sun 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 by children. Non-combustible shielding or
guards may be required.
It is recommended that when an appliance is vented
directly through
a wall, a minimum of five feet of
vertical pipe should be installed to create some
natural draft. This will prevent the possibility
of
smoke or odor entering the dwelling during
appliance shutdown or loss
of power and to keep
exhaust from causing a nuisance or hazard and
exposing people or shrubs to high temperatures. In
any case, the safest and preferred venting method
is
to extend the vent through the roof.
The termination
of the outside chimney of the
pellet stove shall be located in accordance with the
following:
1. Higher than 3 ft. above any forced air inlet (air
conditioner, etc.) located within I0 ft.
2.
Not less that 4 ft. below, 4 ft. horizontally from
or 1 ft. above any gravity air inlet (door,
window, etc.).
3.
Not less that 2ft. 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
ft.
above grade when located adjacent to the public
sidewalks (access).
4. Not less that 3 ft. below an eave or any
construction that projects more that 2" from the
plane
ofthe wall.
5. Distance from bottom of termination and grade-
12 inches minimum. This is conditional upon
· plants and nature of grade surface: The exhaust
gases are not hot enough
to ignite grass, plants
and shrubs located in the vicinity
of the
termination. The grade surface must not be a
lawn.
Connection To A Masonr·y Chimney
Through A Wall
Be sure to verify the construction of a masonry
chimney, as many have combustible framing.
The usc
of single wall flex or rigid 24 gauge
galvanized or stainless steel pipe as a liner is
approved.
Connection To An Existing Class A
Chimney
A chimney adapter can be used to make the
cmmection from 3
", 4", or 6" pellet vent pipe to
existing UL chimney system. Verify with the pipe
manufacturer that your pipe brands will
interconnect.
The use of single wall flex or rigid 24
gauge galvanized or stainless steel pipe as a liner is
approved.

INSTALLATION
Horizontal ExhaustThrough Wall
I. Position appliance on noncombustible hearth pad.
Locate the center of the exhaust pipe on the
appliance. Extend that line to the wall. Once you
have located that center point on the wall, use a saw
to cut a 7"/175mm diameter hole (for 3"/75mm
vent), 8"/200mm (for 4"/IOOmm vent) or
12"/300mm (for 6"/150mm vent). Now you are
ready to install the wall thimble (PL type). Use either
Ryder or Dura- Vent pellet vent pipe.
2. (Optional) Locate and cut a hole for combustion air
pipe using step one procedure.
3. Install a length of pipe approximately 12"/300mm into
the wall thimble and seal pipe joints.
4. Push the lll1it lll1til the pipe connects to the wall
thimble. 1l1e pipe should pass easily through the
wall thimble.
5. If necessary,. bring another pipe length (PL type) to the
outside of the home and connect it to the first section.
1l1e pipe must extend at least 12"/JOOmm away from
the building.
6. Install vertical pipe or if all requirements for direct
venting are met, install vent termination. 1l1e
stainless steel cap tennination supplied by the
Pellet-Vent manufacturer is recommended.
However, if the vent tenninates several feet above
Non-Combustible
Hearth.Pad Cmnbustible
grow1d level and there are no trees, plants, etc. within
several feet, a 45° elbow can be used as a
tennination. the elbow must be tW11ed down to
prevent rain from entering.
Direct Vent
This appliance can be converted to a Direct Vent by
transferring the top flue outlet to the rear vent position,
then follow the directions listed above (Horiwntal
Exhaust 1brough Wall). Although a Direct Vent flue
configuration is an approved installation, the
manufacturer recommendeds that as a minimum, the
appliance be vented directly through a wall, <md at least
five feet of vertical pipe installed to create some natural
dmfl. This will prevent the possibility of smoke or odor
entering the dwelling during appliance shutdown or loss
of power. 'J11is will also keep exhaust from causing a
nuisance or hazard by exposing people or shrubs to high
exhaust temperatures.

INSTALLATION
The models PF70FI and PF70FIB pellet fired wood heaters are approved for installion into a masonry
fireplace or an approved factory-built zero clearance fireplace. Although the minimum venting requires
only a starter section that protrudes past the damper assembly and is sealed at that point, the manufacturer
reccommends that a full3", 4" or 6" liner (listed PL type) be installed from the appliance to termination.

fNSTALLATION
Mobile Home Installation Requirements
Installation· of this appliance into manufactured
housing must follow the instructions for residential
installation, with the following supplemental
requirements
per OAR 9I8-520-0I0 through
918-520-110:
I. Secure the appliance to the floor.
2. Do not disturb the structural integrity of the
home. The chimney must provide for a section
joint so that any parts extending above
13' 6"
from ground level can be removed for
transportation
of the mobile structure.
3. The stove must be grounded to the mobile
home trailer frame-with a No. 8 (minimum)
solid conductor.
4. The combustion air must communicate to the
outside air.
5. Floor protection beneath the unit is required, 4"
in front, 0" on sides and back.
6. Structural members such as
roof trusses or floor
joists cannot be cut
or modified while making
the installation.
Outside Air Provision
Although this section applies to a mobile home
installation, it may also be required by local codes
in standard residential installations.
When connecting to an outside fresh air source, be
sure that the material is not PVC or plastic pipe.
Only
2" inside diameter flexible metal ducting or
flexible high-temperature material should be used.
Steel, aluminum
or copper pipe could be
substituted.
To provide sunicient combustion air, keep the
number
of bends in the pipe to a minimum. If there
is to
be several bends in the fresh air pipe or if it is
to be an extended length. then 2 114" or larger
ducting
is recommended.

OPERATION
ControlPanel Functions
A. Off/On PowerSwitch
The main powerswitch has two positions:
up - OFF
down - ON
B. AugerI InitiateSwitch
Pressing the rocker switch upward will cause the
auger motor to nm as long as you hold the switch in
this position. This will shorten the time needed to get
pellets to drop into the frrepot, particularly after
filling the hopper when it was entirely out of pellets.
Pressing this switch downward starts a 12 minute
cycle which bypasses the snap discs. ·n1e L.E.D.
lamp will change to a light orange color for this
duration.
C. L.E.D. (light emitting diode) Lamp
When this light is on, it indicates that the stove is
operating in the following mode.
Green: Power ON
Red: Cool Down
Orange: Start Mode (12 minute cycle)
D. Fuel Rate S""itch
This rotary switch has four bum rate positions:
clockwise for higher feed rates, cow1ter- clockv.~se
for lower feed rates.

many tmilc; available that is recommended.
Follow the m<mufacturer's installation instructions using
18/2 stat wire. Install \\~re to appliance by cutting the
transparent jwnper wire leads on the control board, then
connect leads to wall thennostat. Once you have
installed the thennost.at, the fuel rate will automatically
be on low when there is no heat demand. When the

MAINTENANCE
ROUTINE INSPECTION REQUIREMENTS
DISCONNECT POWER BEFORE DOING ANY MAJOR MAINTENANCE ON THIS STOVE
The following areas should be inspected periodically to ensure
that the appliance is operating at its
optimum
and giving you excellent heat value:
Firepot I Burner Plate
Inspect the Firepot and Burner Plate periodically to
verify the holes are not blocked with impurities.
If
necessary, clean by removing the burner plate from
the firepot and scrape the surfaces until the holes
are clear. Inspect inner holes
ofFirepot that they
are free
of obstructions (buildup). Remove Firepot
and empty when buildup occurs. The cleaning
frequency will be dictated
by the quality and
quantity of the fuel burned. The following is the
suggested schedule to establish a minimum:
Between 2 days and 2 weeks, depending on the ash
content in the fuel burned. Ash content can vary
from .25% to 1%. Using dirty fuel affects the
cleanliness
of the bum and maintenance frequency.
Remove clinkers or carbon build up as necessary.
Clinkers are a byproduct
of the fuel. Silica (or dirt)
in the fuel, along with other impurities can fuse
under heat and cause clinkering. Clinkering
is a
function
of the fuel, not the stove.
Ash Pan Gasket and Door Gas){et
CAUTION: MAINTAIN GASKETS IN GOOD
CONDITION. DO
NOT LEAVE STOVE
BURNING WITH
DOOR OR ASH PAN DOOR
OPEN
OR AJAR. It is important to maintain
gaskets for an air tight seal. If the Ash Pan Gasket
or Door Gasket become loose over time, glue it
back into position using high temperature (RTV)
silicone sealer as an adhesive.
If the gaskets should
become frayed
or damaged they should be replaced.
Gasket material can be purchased from your dealer
or some hardware stores. Use same size and type
as original.
Door Gasket: 3/4" rope, medium density.
Ash Drawer: 3/8" rope, medium
or light density.
Ash }Jan
This is located under the exterior ash lip (below
door) and
is locked with two spring latches (with
slot heads). Loosen the two slot heads on the ash
pan with a straight blade screw driver by turning
both screw heads counterclockwise. This will
release the spring latches.
Ash Removal and Disposal
CAUTION: BE SURE THE FIRE IS OUT AND
STOVE
IS COLD BEFORE REMOVING ASHES!
NEVER BURN STOVE
WITJ-I ASH PAN DOOR
OPEN.
Ashes can hold live embers for several days, and
must be disposed
ofwith care. Be certain the fire is
out and stove is cold before removing Ash Pan.
I. Brush ashes into Ash Pan.
2. Remove ash pan and dump ashes into a metal
container with tight fitting lid. Store container
away from appliance.
3. Clean and replace Ash Pan and tighten the spring
loaded screws.
The closed container holding ashes should be
stored on a noncombustible surface, away from
combustible materials. Keep ashes in the container
until you are certain all the cinders have completely
cooled. NEVER place ashes in a cardboard box or
any other combustible receptacle. Store pellet fuel
at least 36" away from appliance.
