and
Model
71. The Model 70 Heater meet:; the U.S. Environmental Protection Agen-
cy's Emission limits for catalyst equipped wood heaters sold between July 1, 1990, and
July 1, 1992. Under specific test conditions, the Model
70
heaters have been shown
to
deliver heat at rates ranging from 9800 to
31,100
BTU/Hr. The Model
71
Heater meets
the U.S. Environmental Protection Agency's Emission limits for catalyst equipped wood
heaters sold after July 1. 1992. Underspecific test conditions, the Model
71
heaters have
been shown to deliver heat at rates ranging from 13,100
to

CATALYST EQUIPPED
This wood heater contains a catalytic combustor, which needs periodic inspection and
replacement for proper operation. It is against the law to operate this wood heater in a
manner inconsistent with operating instructions in this manual, or
if
the catalytic element
is deactivated
or
removed.
CATALYST WARRANTY
The combustor supplied with the Model
70
is a set (2) of corning
2"
x

x
7"
x
25
cell
long life combustors. The combustor supplied with the Model
71
is a set

See enclosed catalyst warranty for instruction
on
proper packaging for return shipment.
PROPER FUEL SELECTION
This heateris designed to burn natural wood only. Higherefficiencies and lower emissions
generally result when burning air dried seasoned hardwoods, as compared to softwoods
or
to green
or
freshly cut hardwoods.
DO
NOT BURN:
·Treated Wood
·coal
•Garbage
•cardboard
•Solvents ·Trash
·colored
Paper
Burning treated wood, garbage, solvents, colored paper
or
trash may result in release of
toxic fumes and may poison or render ineffective the catalytic combustor.
Burning coal, cardboard,
or
loose paper can produce soot. or large flakes of char
or
fly
ash that can coat the combustor, causing smoke
spilla~e
into the room and rendering the
combustor inellec.tive.
ACHIEVING CATALYTIC LIGHTOFF
The temperature in the stove and the gases
enterin~J
til'.:· combustor must be raised
to
be-
tween 500 deg. F to 700 deg. F for catalytic activity
to
be initiated. During the start up
of
a cold stove
••
'·
)1urn
to high firing rate must be maintained for about 20 minutes. This
ensures that the stove, catalyst. and fuel are all stabilized at proper operating temperatures.
Even though it is possible
to
have gas temperatures reach
600
deg. F within two
to
three
minutes alter a lire is started, if the fire is allowed to die down immediately it may
go
out
or the combustor may stop working. Once the combu5'or starts working, heat generated
in it by burning the smoke will keep it working.
4
ACHIEVING CATALYTIC LIGHTOFF-
WHEN REFUELING
During the refueling
and
rekindling of a cool lire, or a fire that has burned down
to
the char-
coal phase, operate the stove at a
medium
to
high
firing rate
lor
about
10
minutes to ensure
that the catalyst reaches approximately 600 deg.
F.
CATALYST
MONITORING
It is important to periodically monitor
the
operation
of
the catalytic combustor
to
ensure
that it is functioning properly and to determine when it needs to be replaced. A non-
functioning combustor will result
in
a
loss
of heating efficiency, and an increase in creosote
and emissions. Foflowing is a list
of
items
that should
be
checked on a periodic basis.
'Combustors
should
be
visually Inspected at least three times during the heating season
to determine
if
physical degradation
has
occurred. Actual removal of the combustor is not
recommended unless more detailed inspection is warranted because of decrease in per-
formance. If
any
of
these conditions exist, refer to Catalyst Troubleshooting section
of
the
owner's manual.
'This
catalytic heater is
equipped
with
the
means
to instafl a temperature probe to
mon
itor
catalyst operation. Properly functioning combustors typically maintain temperatures
in
ex-
cess
of
1000 deg.
F.
Ifcatalyst temperatures are not in excess of 500deg.
F.
refer to Catalyst
Troubleshooting section
ol
this owner's
manual.
You
can get an indication
of
whether the
catalyst isworking bycomparing the amount
of
smoke leaving the chimneywhen the smoke
is going through the combustor and catalyst light-off has been achieved to the amount
of
smoke leaving the
chimney
when
the smoke is not routed through the combustor (bypass
mode).
Step 1 - Light stove
in
accordance with instructions.
Step 2 •
With
smoke routed through the catalyst.
go
outside and observe the
emissions leaving the chimney.
Step 3 - Engage
the
bypass mechanism and again observe the emissions leaving
the
chimney.
Significantly more smoke should
be
seen when the exhaust
is
not routed through
the
com-
bustor (bypass mode). Be careful not to confuse smoke.with steam from wet wood.
A CAUTION AGAINST OVERFIRING
Do
Not
Overfire
This
Heater.
Attempts to achieve heat
output
rates that exceed heater design specifications can result
in
permanent damage to the heater
and
to the catalytic combustor.
MAINTAIN PROPER DRAFT
Draft isthe force
which
moves airfrom the appliance
up
through
the
chimney. The amount
of draft in your
chimney
depends
on the length
of
the
chimney, local geography,
nea
rby
obstructions, and other factors. Too much draft may cause excessive temperatures
in
the
applianceand
may
damage
the
catalytic combustor. Inadequatedraft
may
cause backpuff-
ing
into
the
room and
"plugging"
of
the
chimney
or the catalyst.
Inadequate draft will cause the appliance to
leak
smoke into
the
room through appliance
and chimney connector joints.
An
uncontroflable burn ora glowing red stove part or chimney connector indicates excessive
draft.
5
ASH REMOVAL
Whenever ashes bui
ld
up
in
the firebox and when tne fire has burned do
wn
and cooh
r
em
ove excess ashes. Leave an ash bed approximately 1inch deep on the firebox
bott<
to help maintain a
hot
charcoal bed.
Ashes should be placed in a metal container with a tight fitting li
d.
The closed contair
of ashes should be placed
on
a noncombustible floor
or
on
the ground, away from all cot
bustible materials, pending final disposal. The ashes should be retained in the closed
cc
I
atn
er until all cinders have thoroughly cooled.

INSTALLATION PRECAUTIONS
Extensive field and laboratory testing has shown that catalytic stoves perform best as
fireplace inserts when:
1.
A positive sealing direct connect kit
is
used to connect the stove exhaust outlet
directly to the masonry flue
of
the fireplace when flue liner size is approximately the
same size
as
the heater flue gas exit. A rain cap is also recommended
to
keep flue dry
thus allowing a hotter draft.
NFPA211 Code: The National Fire Protection Association code requires all fireplace
insert heaters
to
be positively connected from the heater to the flue liner.
2. An equivalent sized oval flue liner is installed when the flue liner size is larger than
the heater flue gas exit. Connection must be from stove exhaust outlet extending the
lull height
of
the chimney and must include a rain cap.
3.
Height of the chimney is at least 15 feet tall.
4. Location
of
chimney is interior (not on an outside wall).
Satisfactory results have been reported with installations other than as listed above.
However, as all chimneys draw differently, problems with performance may be encountered
ifsteps are not taken to keep the chimney hot. Adraftbetween .03 and .06 inches of water
is recommended for proper catalytic operation.
Use the following
to
complete the installation of the unit as an insert:

Minimum Clearances:
The Model 70 and
71
Fireplace Inserts are intended for installation
in
accordance with the
standard for chimneys, fireplaces, vents, and solid-fuel burning appliances, NFPA-211 Code.
This model is not intended for installation intofactory-built metal fireplaces or lor use with
a metal chimney.
1. The hearth must
be
of masonry construction and must extend a minimum
of
16"

POSITIONING THE HEATER
When positioning the heater, the
following conditions MUST be
met! (See Figure
3)
1. The front
of
the damper open-
ing must be positioned BEHIND
the rear edge of the lintel
to
ensure proper draft.
(See Figure 3)
2. The vertical plane of the fire-
place front must fall BEHIND
the side cold air vent on top of
the unit. (In other words, it is
possible to have the heater too
far in
as
well asnot farenough.)
3. Center the heater
in
the fire·
place opening.
MOUNTING THE TRIM PANELS
Alter the unit is positioned, as
shown in Figure
3,
mark
the
mounting position
of
the trim
panels as follows:
1. Set the top (long) trim panel
in
place on top of the
un
it. The
panel should be flat against the
outside face of the fireplace,
and standing vertically. Mark
along the loweredge of thetrim
panel with a pencil to make a
reference line for mounting.
2. Set the side trim panels in
place, again flat against the
lace
of the fireplace. Mark
downthe inside edge of the trim
panel
to
make
a
vertical
reference line.
NOTE: For short depth
(17"
to
19112") see Figure 7.
3.
Slide the unit out
of
the fireplace far enough to work behind the trim panel reference
lines.
4. CAUTION: If optional fireplace trim kit brass will be used on the trim panels. set the
trim panels out 5116"
to
allow for brass overhang.
5. Mount the side trim panels. (See Figure 4)
a.
Position the trim panel on the reference line.
b. Drill Mounting Holes in center
of
trim panel mounting brackets to allow for
adjustment in and out if necessary.
c. Mount the trim panel using the self-tapping screws provided.
6.
Mount top trim panel to side panels with screws provided
as
indicated
in
Figure
4.
7.
Ifdesired obtain optional brass trim from box and assemble using
an
"ell"
bracket in each
corner where the top and side trim joins. Tighten set screws joining trim together.
8.
Next slip the brass trim over the top edge of the trim panels and slide all the way
down until sides and tops interlock. Obtain screws provided and lock brass trim in place.
(See Figure
5).
9. Slide the unit back
into
the fireplace. Check to be sure that the trim panels (and brass)
are properly positioned and lie flat against the front ofthe fireplace. Ifone or more of the
panels is out of position, slide the unit out and reset by loosening the mounting screws
and repositioning in the slot. (See Figure
6)
.
NOTE: If side and top panels gap due to unevenness of fireplace (normally on rock
faced fireplaces). you will need to drill a
5/32"
hole through both side and top panels
near where the panels intersect and install a #10 self threading screw to eliminate the
gap (paint screws to match).

4. Plug the power cord into a
115
VAC outlet.
5. Place crumpled pieces of newspaper in the stove. Light it and close the doors.
Ensure that the stove draws properly through the primary drafts.
6. Check for smoke leaks around the doors.
7. Open the doors and check for smoke escaping from the front of the stove. Smoking
usually indicates a defective or poorly positionud chimney. Some chimneys with a
marginal draft can be preheated by lighting newspaper and holding it near the open
damper
w1th
a poker or fire tong. Once the chimney heats up, a proper draft can
usually be obtained.

A INSTALLATION PRECAUTION
Extensive field and laboratory testing has shown that calalytic stoves perform best as
freestanding stoves when vented into a masonry chimney when:
1. A rain cap is installed
on
the chimney.
2. Height
of
chimney is at least 15 feet tall.
3.
location
of chimney is interior (not on an outside wall).
4. In a high pitch
or
chalet ceiling, use a minimum amount of single wall pipe but never
run more than five
(5)
feet.
long
lengths of single wall pipe will result in rapid cooling
of
the flue gas and heater draft and performance will be affected.
NOTE: Certain types of double wall pipe (close clearance) also cause a substantial drop
in flue
gas
temperature.
If
a double wall pipe connector is being contemplated. check with
the pipe manufacturer to ascertain that the use of their product will not affect the flue gas
temperature. Do not use double wall pipes which reduce flue gas temperatures.
Satisfactory results have been reported with installations otherthan listed above. However.
draft problems are possible if a hot chimney is not maintained.
•Use pedestal kits as follows:
Model 70

FINAL CHECK
1.
Recheck the specified clearances.
2. Remove all foreign material from the firebox area.
3. Open the primary air drafts and damper bypass.
4. Plug the power cord into a 115 VAC outlet.
5. Place crumpled pieces of newspaper in the stove. Light it and close the doors. Ensure
that the stove draws properly through the primary drafts.
6. Check for smoke leaks around the doors.
7. Open the doors and check for smoke escaping from the front of the stove. Smoking
usually indicates a defective
or
poorly positioned chimney. Some chimneys with a
marginal draft can be preheated by lighting newspaper and holding it near the open
damper with a poker or fire tong. Once the chimney heats up, a proper draft can
usually be obtained.

SECTION V
WOOD HEATER SAFETY
Certain safety hazards are inherent in
any
wood heater installation. You should be aware
of these so that a safe and proper installation can be made.
1. FAULTY CHIMNEY:
An
older masonry chimney should be thoroughly checked to be
sure there are no holes
or
weak spots which could allow sparks
or
hot gasses to
escape.
2.
HEAT CONDUCTION:Placing combustible materials too close to a heater or chimney
can be a fire hazard.
By
keeping these particular hazards in mind as you install and use your room heater
you can ensure a safe, reliable installation.
SAFETY PRECAUTIONS
For your protection, read and follow these safety precautions closely:
1. Use a spark arresting shield
(3/8"
mesh) on top of the chimney. Check monthly as
this is a code requirement
in
some areas.
2. Use smoke detectors around the heater as well as in sleeping areas.
3. Keep a fire extinguisher rated for Class
"A"
fir&s near the heater.
4.
Check with your insurance company
to
be sure your policy covers the installation
and use
of
a wood fired room heater.
5. Creosote-Formation and Need for Removal: When wood isburned slowly, it produces
tar and other organic vapors, which combine with expelled moisture to form creosote.
The
creosote vapors condense in the relatively coot chimney flue of a slow-burning
fire. As a result, creosote residue accumulates on the flue lining. When ignited this
creosote makes an extremely hot fire.
Theconnectorand/orchimneyshould be inspected at least once a monthduringthe heating
season to determine
if
a creosote buildup has occurred.
If
creosote has accumulated, it should be removed
to
reduce the risk of a chimney fire.
6. Locate furniture and any other combustible away from the heater.
7. Store firewood at a safe distance from the heater.
8. Disposal
of
Ashes:
Ashes should
be
placed in a metal container with a tight fitting
lid. The closed container of ashes should be placed on a noncombustible floor
or
on the
ground, well away from all combustible materials. pending final disposal. If the ashes
are disposed of byburial in soil or otherwise locally dispersed, they should be retained
in the closed container until all cinders have thoroughly cooled. Ashes can ignite
up to 72 hours afer removal.
9. Always exercise caution when using your heater. Be particularly careful when there
are children around an operating heater.
CAUTION!! A NEVER use gasoline, gasoline-type lantern fuel, kerosene, charcoal
lighter fluid
or
similar liquids
to
start
or
"freshen
up"
a fire in the heater. Keep all such
liquids well away from the stove when
it
is in use. All fluids
of
this type give off volatile
fumes and can and
WILL
EXPLODE!! Don't take a chance with the safety
of
your home
and family.
