Keep the manual available for future reference. The manual is
an important part of your stove. If your stove is sold, deliver the
manual to the new owner along with the stove.
The quality of the installation (especially the chimney connector
and chimney), and the quality of the fuel being burned will affect
the performance of your stove, but the most important factor
is the way you operate the stove. With the help of this manual,
you will learn how to effectively heat and cook with your stove.
Be sure to read it entirely, including the terms of reference and
function.
In addition, your own experience will help you to learn the role
that the chimney plays in stove performance. The Oval &
Sweetheart have been tested and are listed by Underwriters’
Laboratories of Canada and Underwriters’ Laboratories in the
U.S. The test standards are ULC S-627 and UL 1482.

Before removing the oval stove from the skid, the flu body must
first be attached tothe stove back. Follow the instructions
below.
1) unscrew the flu body from the skid and set aside.
Warning: The stove is very heavy. Since the legs may dig into
a soft floor, do not locate the stove, or even set it to rest, on a
surface that could be imprinted.
We recommend that 3 or 4 persons be available to assist in the
lifting of the stove, and that gloves should be worn to protect
hands from cuts.
2) unscrew 3 sheet metal screws (2 along the bottom of the
oven at the bottom and 1 along left side - see illustration)
3)Remove the first level only of nuts and washers from the
screws extending out the back of the stove (7pcs)
4) place flu body on back of stove so that the nuts on the
screws fit inside the holes in the flange on each side of the flu
body.
5) while holding the flu body in place, attach the flu to the stove
by putting on a washer and nut on each screw, hand tight only.
6) install the sheet metal screws along the bottom and side of
the flu body, and tighten up.(3)
7) tighten up the remaining nuts (7)
back of stove
1) First, remove the screws that are holding the flu body to
the skid and remove the flu body.
2) Next, unscrew the two lag bolts which are securing the
front and back of the firebox base. Lighten the stove by
removing the keyplate and lids.
3) Look under the oven and note that the stove must be lifted
up, over the wooden brace located there.
4)With 2 persons on the heavier, firebox side (left), and one
person on the other side, lift the stove up, off of the skid and
onto its new location.

SweetHeart
Warning: The stove is very heavy. Since the body frame may
dig into a soft floor, do not locate the stove, or even set it to rest,
on a surface that could be imprinted.
The Sweetheart is resting on a pad of styrofoam on the skid.
It consists of the range and a base assembly package.
The base assembly should be assembled and in position prior
to lifting the stove off of the skid; the base assembly instructions
follow below.
Base Assembly (Sweetheart only)
1.Unpackage the base sections, legs and hardware package
which are are located in a carton fastened to the skid at
rear of the range(it would be a good idea to check for any
damage that may have occured during shipping).
2. Screw the base levelling bolts (with teflon glider attached)
into each of the four legs. The levelling bolts are located in
the hardware package. When installing the levelling bolts,
the teflon glider should
extend
beyond the bottom of the
leg by approximately 1/8"-1/4". Adjusting levelling bolts
in too far will cause the leg to drag on the floor potentially
causing damage to flooring. (see figure 1 ) . Check that
gliders and floor are free of any debris, this will ensure you
do not scratch your floor.
Painted section goes to the rear
3. Assemble base to legs using the nuts and bolts provided.
The shorter base sections are the sides. The longer
sections are front and rear.(the black painted section goes
to the rear, see fig. 1).
4.Hand tighten the nuts and bolts until the base is completely
assembled. Ensure that all base sections are installed
with the body mounting flange up.
5. Adjust base sections to the most upper position and
tighten up the nuts and bolts.
Assemble Stove to Base
1. The range body rests directly on the base - no bolts are
required. We recommend that 3 or 4 persons be available
to assist in the lifting of the stove, and that gloves should
be worn to protect hands from cuts.
2.Do not lift the stove by the nickel trim. With 2 persons
on the heavier, firebox side (left), and one person on the
other side, lift the stove up, off of the skid and onto the base
assembly. If possible, have a fourth person remove the
skid while the others lift.
3.In order not to damage the nickel trim lift the range from the
front and the rear . The person at the front can first open
the oven door and use the oven opening for a hand hold.
The rear of the oven body at the bottom can be used to lift
from the back.

4. Lift the range off the pallet and onto base, making sure the
range is sitting square and level on base. The stove sits
over the lip of the base assembly. Helpful hint: Instead of
trying to square the entire stove over the base, put one side
or back on first then slowly lower the other side into
position.
5.To level the stove, simply adjust the
levelling screws with teflon pads located
at the bottom of each leg (the ones you
assembled in step 2). Using a 5/16 (8
mm) open end wrench turn the adjusting
1/8"- 1/4"
screw clockwise to raise up the corner,
and counter-clockwise to lower the
corner. (Don't forget the teflon glider
should
extend
beyond the bottom of the
leg by approximately 1/8"-1/4")

The handle should be able to pivot freely from this point.
Tighten the nut securely, so it can't work loose under
normal use.
2. The three pronged tool holder (#1440) is used to hang the
lid lifter, poker and scraper.
To mount the holder, locate the two 1/4” holes on the
firebox side of the warming cabinet back. Fasten with the
bolts supplied.
3. A pipe damper installation is optional depending on your
installation and chimney configuration. Your dealer can
supply you with a damper.
The damper installation should be done before final assembly
of the chimney.
a) Open the front cabinet door.
b) Mark the spot for drilling in the back of the pipe by
pushing the sharp end of the damper rod into the back wall
of the pipe before drilling.
Cabinet Assembly
See the manual entitled "Cabinet Assembly Instructions for
Gas,Electric,Combination and Wood Stoves" which is
included in the cabinet box.
(Oval and SweetHeart)
c) Drill a 1/4” hole in the middle of the smoke pipe
through the centre of the hole in the back of the cabinet.
:
d) Follow the instructions that came with the damper and
install the damper inside the cabinet with the handle of the
damper also inside the cabinet.
e) Make sure the damper disc rotates freely inside the
pipe.

Installation
Be sure to read the sections on clearances, floor protection
and chimneys before actively starting the installation. Contact
local building or fire officials about restrictions and
installation in your area.
Clearances
A woodburning stove radiates heat in all directions. Heat
directed toward living areas in front of the stove is usually very
welcome.
However, heat radiating in other directions will not be as
welcome if it results in overheating nearby walls, ceilings and
floors.
An important part of planning a safe installation is to be sure
that combustible material located near your stove does not
overheat.
Clearance is the distance between your stove and stovepipe
and nearby walls, ceilings and floors.
If there is adequate clearance, then the nearby surfaces will
not overheat.
The clearance distance should be empty except for noncombustible heat shields.
Do not fill the empty space with any insulating material.
If you plan to install a Fresh air Kit with your stove, be aware
of the greater clearances required. See page 9 "Chart ofClearances" and page 12 "Fresh Air Kit" for more information
Be aware that as wood is exposed to continuous heat it dries
out, eventually lowering the temperature at which it will start on
fire.
Maintain the clearances outlined in this manual, particularly
with respect to nearby combustable surfaces.
Your Heartland cookstove has been tested for safe operation
providing that these guidelines are followed.
Clearances must be maintained to
all combustible material. These
include doors, trim, furniture, drapes,
newspapers and clothes.
Air flowing between the stove and stovepipe and nearby
surfaces carries away heat.
An optional heat shield kit is available
for our woodstoves for reduced
clearances. See page 11 on "Heat
Shield Kit"

A chimney approved to ULC standard S629 in Canada or UL 103HT in the U.S. must be used to connect the smokepipe
at the top of the cabinet to maintain the 2" clearance to combustibles. The approved chimney must extend 1" below the heatshield.

Clearance Reductions
There are many alternate decorative methods to reduce
clearances to combustible materials. See your dealer, or local
fire or building official to ensure the appropriate standards are
being met with these alternatives. In Canada, refer to the
Installation Code for Solid Fuel Appliances and
Equipment. CAN3-B365-M84. In the U.S., refer to the National
Fire Protection Association Standard 211,
Floor Protection
The chimney ‘drives’ the system by producing the draft that
draws in combustion air and exhausts smoke and gases to
outdoors.
When installing a new woodburning system or upgrading an
existing one, give as much attention to the chimney as you do
to the appliance that it serves.
The Oval and Sweetheart can be installed in a masonry
chimney which is in compliance with the appropriate standard
or a prefabricated chimney approved to
in Canada and UL 103HT in the U.S.
ULC Standard S629
When installing this cookstove on a combustible floor, a
noncombustible floor protector is required under the stove. The
floor pad is to protect the floor from hot embers that may fall
from the loading door. The floor pad must be continous
noncombustible surface. Floor tiles with grouting between
them or sheet metal pads are acceptable. The pad must
extend 450 mm (18") beyond any side with a loading door and
200 mm (8") beyond the other sides and rear. (See page 7
"Oval Rough-in Dimension Diagram" or page 8 "SweetHeartRough-in Dimension Diagram".) Floor pads may be fabricated
from non-combustible materials. (see page 26 "Formula for
Equivalent Hearth Extension")
Chimneys and Draft
The chimney is the most important element of successful
stove operation. (see also page 23 "Flue Pipes")
Performance of your woodburning system depends more
on the chimney than on any other single component.
Follow the chimney manufacturer’s directions for installation.
We recommend that prior to installing your stove into a
masonry chimney, you have the chimney inspected by a
qualified mason. An unlined masonry chimney should not be
used without the installation of a liner.
The chimney and installation will have to be inspected by your
local building inspector.
Recommended Chimney Clearances
The chimney must:
•extend at least 14 ft. above the collar of the stove;
•extend at least 3 ft. above the point where it passes
through the roof;
•be at least 2 ft. above anything within a 10 ft. radius of the
top of the pipe.
Good draft in a cold chimney should be between 0.01" and
0.15" “water column” (your dealer may be able to check this
for you).

Stovepipe Chimney
Connection Requirements
1. The stovepipe chimney connector should be made of 24
gauge or thicker sheet metal and should be 6” in diameter.
2. The last section of the chimney connector starting from
the stove should be screwed to the flue collar of the stove.
Individual sections of the chimney connector must be
screwed together with at least three sheet metal screws.
The last section should be securely attached to the
chimney. Be sure there are no “weak links” in the system.
3.The crimped ends of pipe sections should point downward
toward the stove so that any soot or creosote that falls
from the inside of the pipe will be funnelled into a clean out
or fall into the stove.
4.The chimney connector should be at least the height of the
warming cabinet before a 90 degree turn is installed, with
no more than two 90 degree turns.
5.A horizontal run of stovepipe should be no longer than 4 ft.
A vertical run of stovepipe to a prefabricated metal chimney
should be no longer than 8 ft.
Optional Accessories
Accessories may be obtained from your dealer or call us direct
at 519-650-5501. Our office hours are from 8:30 a.m. to 5:00
p.m. est
Heat Shield Kit
A space saving heat shield kit enables you to install your
cookstove as close as 2" (51mm) to a combustible wall!
Installation is Easy
The heat shield kit is available for both Oval and Sweetheart
cookstoves and mounts directly on the rear of the stove. The
main section of the shield covers the firebox and oven of the
cookstove, while the upper section covers the flu pipe to the
height of the warming cabinet.(See illustration, Fig. 4.)
An installation and operating manual is packed with every Oval
and Sweetheart heat shield kit. Extra copies may be obtained
from your dealer or by contacting Heartland Appliances Inc.
6. Do not pass the stovepipe chimney connector through a
combustible wall if it can be avoided. If this cannot be
avoided, follow the recommended in CSA B365 in Canada
and NFPA 211 in the U.S., recommendation on Wall
Pass-Throughs.
7. Do not use single wall smokepipe as an outside chimney.
8. Never pass stovepipe chimney connector through a
combustible ceiling.
9. The whole chimney connector should be exposed and
accessible for inspection and cleaning.
10. Galvanized stovepipe should not be used. When exposed
to the temperatures reached by smoke and exhaust
gases, galvanized pipe may release toxic fumes.
11. Horizontal runs of chimney connector should slope upward
1/4” per foot going from the stove toward the chimney.
12. During a chimney fire, the chimney connector may vibrate
violently. The connector must be securely attached to the
pipe and chimney, and individual sections must be securely
attached together.
13. This stove is not to be connected to an air distribution duct.

Fresh Air Kit
Installation is Easy
A fresh air kit enables you to use outside air, instead of room
air to fuel the fire. Using an outside source for combustion air
has its advantages. If your home is tight and well insulated,
then the fire in the stove may be “starved” of combustible air,
it will be difficult maintaining a fire, and you may have back
drafting problems.
During the heating season, cold air, (which is more dense than
warm air), will cause the fire to burn a little hotter, resulting in
more BTU’s from your wood, and less creosote build-up.
Figure 5
Illustration of Oval with
fresh air kit
Fresh air kit
The water jacket can be installed in the stove in less than a
minute using only a slot screwdriver. The water jacket is a
hollow baffled chamber that fits in the firebox. Two pipes and
a pump installed from the water jacket to the electric or gas
water heater, circulate heated water from the stove to the
storage tank. (See illustration, Fig. 6.)
Installation is Easy
Mounting holes and airways are all pre-punched on all new
Oval and Sweetheart cookstoves.(see figure 5)
Simply remove the cover plates (right side of firebox on the Oval
and, bottom of the firebox on Sweetheart). Now you are ready
for installation. A complete set of diagrams and instructions
are included with each fresh air kit.
Please note that some States require a fresh air source to be
installed with wood burning appliances. Please check your
local, and state, building codes.
Water Jacket
The average family spent about one quarter of their utility bill
to heat water last year. By installing the water jacket in your
cookstove, you can reduce or virtually eliminate your hot water
utility bill.
Figure 6
A Sample Oval Water Jacket Installation
This is an illustration of an active or pumped
circulating hot water system.
You can expect from 8 to 10 gallons or more hot water per hour
(about 10,000 BTUs) from your oval water jacket, OR 6 to 8
gallons (about 8,000 BTUs) from your Sweetheart water
jacket.
Because cold water cools the water jacket in the firebox,
creosote will be attracted to its cool surface, like humidity
being attracted to a cold window. These deposits will quickly
burn off thus reducing creosote formation in the stove and
chimney.
An installation and operating manual is packed with every Oval
and Sweetheart water jacket. Extra copies may be obtained
from your dealer or by contacting Heartland Appliances Inc.

Understanding Combustion
Water: Up to half the weight of
freshly cut logs is water. After proper
seasoning only about 20% of the
weight is water. As the wood is
heated in the firebox, this water
boils off, consuming heat energy in
the wood, the more heat energy is
consumed. That is why wet wood
hisses and sizzles while dry wood
ignites and burns easily.
Smoke (or flame): As the wood heats
up above the boiling point of water, it
starts to smoke. The hydrocarbon
gases and tars that make up the
smoke are combustible if the
temperature is high enough and
oxygen is present. When the smoke
burns, it makes the bright flames that
are characteristic of a wood fire. If the
smoke does not burn, it will condense
in the chimney forming creosote or
exit the chimney as air pollution.
figure 7
Charcoal: As the fire progresses
and most of the gases have vaporized,
charcoal remains. Charcoal is almost
100% carbon and burns with very
little flame or smoke. Charcoal is a
good fuel that burns easily and
cleanly when enough oxygen is
present. Of the total energy content
of the wood you burn, about half is in
the form of smoke, and half is
charcoal.
Break-in Fires for New Stoves
If this is your first fire, OR you have installed a replacement set of brick, read the procedure for break-in fires.
Proper seasoning ensures longer stove life.
Fuel
Woodburning
The firewood you use will make an important contribution to successful operation. You will achieve the best performance and
overall efficiency by burning firewood that has been split, stacked and air-dried undercover from rain for at least one year. Burning
improperly seasoned or “green” wood can be a frustrating experience leading to poor performance, smoky fires and a build-up
of creosote. Do not burn saltwater driftwood refuse, rubber tires, etc. Use of improper fuels can cause a fire hazard and lead to
a premature deterioration of the stove components, voiding the warranty. (See Fig. 7 Understanding Combustion.)
Burn dry wood because:
•it gives up to 25% higher efficiency;
•it produces less creosote;
•it ignites faster and smokes less;
•valuable heat is lost in the fire as it dries out wet wood.

Getting Acquainted
The Sweetheart and Oval cookstove are time proven heating
and cooking appliances. Take your time to acquaint yourself
with the principles on which your new stove operates as a
heater and cooking stove.
Understanding the primary principles of the air intake controls,
the oven damper, the flame path for the fire and the relationship
to the chimney will give you a very comprehensive understanding
of what you are trying to accomplish with the stove.
Before starting the stove, lift the key plate handle and rest the
arm in the top hook of the cabinet bracket. Open both the top
loading and ash pan doors. The doors open by lifting slightly
over the hook and pulling towards you. Always use the lid lifter
to open doors and bell dampers and when adjusting the oven
damper.
In the Oval, looking into the firebox through the top you see
cast iron liners, these liners rest on an oval refractory firebrick.
In the Sweetheart, looking into the firebox through the top you
will see firebrick liners on the left and right side of the firebox.
At the bottom of the firebox is the wood grate, looking in
through the ash pan door, you will see the wood grate pull—
slide it back and forth and looking down into the firebox you will
see the slots open and close.
You will notice that with the ash door closed the ash flap may
be lifted to access the wood grate pull without having to open
the door.
Burning skid wood or construction materials with nails is not
recommended as anything in the firebox that will not burn has
the potential to get caught in the grate.
The ash pan is directly below the grate.
Starting the Stove
Good safety practices:
Educate your family members:
•before burning the stove, have each family member read
this manual and be aware of safety practices;
•keep children, clothing and furniture away from the stove;
•the stove is HOT while in operation – DO NOT TOUCH the
stove, contact may cause burns;
•open the firedoor, ash pan door, woodgrate pull, bell
dampers and oven damper with the 1415 lid lifter only—
these surfaces get hot; (see figure 8)
The stove is burned with the slots open which allows the
wood grate pull
slots open and close
combustion air to enter underneath the fire. As ash and coals
build up on the grate these slots fill and will require the
occasional “shaking”.
It is a good policy to shake the grate or stir the coals with the
poker before loading a new charge of wood.

Break-In Fire
(Refer to page 13 figure 7)
Flu Gases
The firebox of your stove is made of superior materials—cast
iron and firebrick lining.
Both materials could be broken by a sharp blow or thermal
shock. A little extra care and thoughtfulness during the breakin period will help promote a long life for your stove.
The cast iron and firebrick will have picked up moisture during
shipping and storage.
During the break-in period it is important to let the cast iron and
firebrick slowly dry out and avoid thermal shock, caused by
strong hot fires.
•Build a small kindling fire (following the instructions below
for the first fire) and add small pieces of kindling. Let the
stove burn for approximately one hour on the first firing.
•Let the stove cool keeping the doors closed.
•Repeat the process for a few days or until you have had six
break-in fires. You may notice some smoke or “burnoff”
during your initial firing. This is normal and is caused by
the curing of the paint finish.
Oven Damper
Figure 9 - shows oven damper open
Lighting the ‘charge’ is of your personal preference. One
method is to roll a piece of newspaper into a torch, lighting
one end and using it to start the paper.
Light the paper at the bottom of the load and then light the
paper at the top, shut the key plate immediately. You may
find it helps to hold the key plate open just slightly for a few
seconds to give some extra air and establish the fire.
Your First Fire
It is advisable to read and understand this section thoroughly
before starting the fire (Refer to page 12 figure 7)
1. Open the oven damper (see Fig. 8 and 9) and air intake
controls (bell dampers). On damp cold days, it may help
to open the ash door slightly until a good draw develops in
the chimney.
2. To kindle a fire. Lift the key plate lift handle and rest it in
the top slot of the closet bracket. Crumple six to eight
single sheets of newspaper into loose balls and place
them on the wood grate. Cut 10-15 pieces of kindling into
strips approximately 1/2” by 1/2” by 10” long.
Place the kindling on the newspaper. Place 2 or 3 more
pieces of crumpled newspaper on top of the kindling.
Ensure that the wood grate slides are open.
3. To Fuel the Fire. After a couple of minutes lift the key plate
or open the front loading door slowly. When the kindling is
established add larger pieces, perhaps 2”x2”x10” long.
Continue this process until the fire is established when
split logs can be added.
Dampering the stove. Tighten the bell dampers to
approximately 1/4” opening. This will slow the fire down.
Wait momentarily and close the oven damper.
The smoke and heat is now being routed around the oven.
Remember, by closing the oven damper resistance has
been put on the system.
If the stove/chimney is not yet heated enough or there is
too much volume of fire going through, this additional
resistance will cause backpuffing.
Close the oven damper slowly (Fig. 9) to allow the oven flue
chamber to absorb the smoke and heat.
15
4. Reloading the stove—Stove tending time will be greatly
reduced if you reload your stove while the system is still
hot and there is plenty of hot embersl to rekindle the fire
quickly. Including some smaller pieces of wood in the new
fuel load will help the stove regain temperatures quickly.
When reloading, open the oven damper and wait
momentarily—if loading from the top—slowly lift the key
plate or if loading from the front, open the door slowly.
Load wood—smaller, split pieces first.
Close the door or key plate.
Open the bell dampers slightly.
Sweetheart:
To use the summer position in the SweetHeart you will need
to purchase the optional #4271 summer grate support. Call
your dealer to order, or call direct to Heartland
1.Remove the wood grate from the lower firebox position by
pulling the grate up, back end first, and out of the firebox.
2. Remove the wood grate slide from the wood grate. Place
the "summer position wood grate stand" at the back of the
firebox on the firebox extension.
3. Place the fire grate so the back of the fire grate rests on
the stand, and the front rests on the top of the front brick.
The stove must rebuild its thermal momentum before
closing the oven damper.
As you become more experienced you will gain knowledge
on what settings of bell dampers and oven dampers can be
used at the different stages of the woodburning cycle (see
Combustion Process, page 13 figure 7).
Summer Burning
Both Oval and Sweetheart stoves feature a utility which allows
you to use your stove during the summer months with less
heat radiating from the firebox.
Oval:
1. Slide the wood grate from the lower firebox position and
remove the wood grate slide.
2. Set the wood grate on top of the firebrick. You are now
ready for summer cooking.

Coal Burning
Do not burn coal on the wood grate. An optional coal grate kit
is available for the Oval (#1500) and the SweetHeart (#4500) to
burn coal. An installation and operating manual is packed with
every Oval and Sweetheart Coal Kit. Extra copies may be
obtained from your dealer or by contacting Heartland Appliances
Inc. Below is a brief description of the coal kit installation
Sweetheart Coal Grate Installation
To install the optional coal grates, remove the lift handle, the
key plate and lids. Lift the wood grate out through the top of the
firebox and replace it with the coal grate. Remove small front
brick in firebox by unscrewing bolt & nut that holds brick in
place. (Please note that older models require front fire brick to
be installed with the groove facing away from the firebox and
towards the front of the stove).Replace with large brick in coal
kit. Gently tap the coal grate down until it fits snugly into the
steel track. Replace the key plate, lift handle and lids. Then
proceed with firedoor damper installation.

Starting Up a Coal Fire
A chimney 6" in diameters is imperative for the Coal Burning
process. On chimney larger than 6" in diameters will cause
poor ignition of the coal due to inadequate draft.
It is possible to burn coal with a large diameter chimney , but
banking a new bed of coals will require a greater mix of wood
to create and maintain an adequate draft.
Oval Coal Grate Installation
To install the optional coal grate package, remove the wood
grate through the ash pan door and replace with the coal grate.
Remove the key plate over the firebox and slide the coal liners
#1470 in the front and #1475 in the back of the firebox.Replace
the key plate, lift handle and lids. Then proceed with firedoor
damper installation.
Oval and Sweetheart Firedoor Damper
(Coal burning only, see illustration on next column)
The firedoor damper comes with each coal kit and must be
installed. Remove the nickel firedoor frame from the firedoor.
Loosen the three screws that hold the cover plate over the
damper holes. Replace the cover plate with the coal damper,
lettered side out. Tighten screws just enough to hold the
damper plate on but also allow it to slide freely back and forth.
Lock screws in position with a nut on each screw thread.
A wood “break in” fire should be done before attempting
to burn coal (see page 13).
The minimum draft required to maintain an oven temperature
of 350 ºf is around .04" on a water column. For drafts under .04"
on a water column, closing the oven draft damper more than
half way, will cause back puffing.
During the recharge phase of a new bank, a draft of .08" should
be maintained for at least 10-15 minutes or until a substantial
bed of red embers is built up.
We recommend burning anthracite coal, which is relatively
clean to handle, burns evenly with a low flame, has a low
sulphur content and produces relatively little smoke.
Use a “chess nut” or “nut” size of coal, which is 1 3/16 to 1 5/
8 in diameter. However, other coal, such as bitumious, can be
burned, but is inferior to anthracite.
To Start a Coal Fire:
1. Use paper and dry wood kindling to start the fire.
2.Add small, compact pieces of hardwood when the kindling
is burning hot. Keep the primary damper controls fully
open to establish a hot fire quickly.
17
The ash door also may be opened during start-up to
accelerate the initial burn.
3.When a substantial bed of red embers is built up, start
adding coal – small amounts at a time. Keep the draft control
open.
4. Continue adding small amounts of coal until there is a
solid bed of
time. Allow sufficient time between each small loading (at
least five to ten minutes), so that each loading has time
to ignite thoroughly before the next load is put in.
When a substantial bed of burning coals has been
established, fill the stove to the highest possible level, no
higher than the bottom of the firedoor – be careful not to
overload!
A deep bed of coal will always burn more satisfactorily
than a shallow bed.
5. When most of the wood is burned and the coal is
completely ignited (usually five to ten minutes or less
after filling the stove), the draft control should be turned
down to the proper operating level.
(If the ash door has been opened, it
prevent overfiring, which can severely damage the stove.)

NOTE: When burning coal, the firedoor damper must be
kept open. The secondary air is required to aid in
burning off coal gases. The coal damper is not required
when burning wood and should be kept closed when
burning wood.
Coal grates are not to be used in upper (summer)
position. Do NOT fill firebox with coal higher than the
bottom of the firedoor opening.
Disposal of Ashes (wood and coal)
Do not remove the ash pan when the stove is hot. Carry
the ash pan with one hand on the handle in the upright position
and the other on the front handle to balance the pan.
Improper disposal of ashes is the most common cause of
wood stove related fires.
Empty the ash pan before ashes build up over the top.
Recharging the Fire
If the fire is burning hot and there is a deep bed of coals, add
coal a hand full at a time.
Allow enough time between each addition for the combustion
process to start. As the bank becomes larger, the amount of
coal added at a time can be increased.
If the coal bed is under 5" before a recharge is started, it may
be necessary to add kindling wood to increase the combustion
level so that more coal can be added.
1. Coal never should be added unless there is a reasonably
hot fire. The coal bed should be bright and vigorous.
2. If the fire is burning hot and there is a deep bed of coals,
full loads of coal can be added at any time. However, if
there is not a deep bed of coals, it is best to add small
amounts of coal at first.
Use Caution:
•don’t carry hot ashes through the
house;
•even though the stove may be cool,
the ashes in the pan may still be hot;
•never place the ash pan on a
combustible floor;
•never leave the ashes near
combustible material or
combustible liquids;
•always disposeof ashes in a closed
metal container with a tight fitting
lid—if an unexpected gust of wind
fan the the ashes, a fire could result.

Using the Oven and Cooking Surface
Stove top cooking
The cast iron top provides an excellent large cooking area for
griddling, frying, basting and simmering.
Some users report griddling directly on the cooking surface,
although this is not recommended, as it usually creates quite
a mess. A cast iron cooking vessel with a flat bottom is
recommended. As you inspect your new oval, you may find the
edges of your keyplate sitting slightly above the cooking
surface. This is caused by the stiff new gasket under the
keyplate. As the gasket compresses over time, the keyplate
will drop to a position even with the rest of the cooktop.
To allow for normal settling, we have purposely created a slight
upward warp at the middle of your oval
keyplate. As the keyplate heats and
cools it will eventually settle to a flat
position. The time period for settling
will be different for each stove
depending on usage. Please allow a
full season of use as a minimum.
When getting used to cooking on the
stove top remember that the surface is
cast iron and like cast iron cookware,
once heated retains the heat for a long
time.
Successful stove top and oven cooking
will not result from trying to fire the
stove up immediately but by having a
heated stove and ‘banking’ the fire to
retain the temperature required.
The temperatures established on both the cooking surface and
in the oven are determined by three primary things:
1. The amount of draft the chimney has. As the bell dampers
are opened more air gets in the firebox and is drawn
through the stove and chimney, resulting in a faster, hotter
fire.
2. The position of the oven damper. With the oven damper
closed, the heat is channeled under the entire cooking
surface (heating it up) and around the oven (heating it up).
When the oven damper is open, the heat will be routed
directly up the chimney.
Damper Closed

xhaust
The left hand side of the cookstove top
will be the hottest as the fire burns
directly beneath it. The surface will get
cooler the further you go to the right.
The oven damper can be used to help
control the heat on the cooking surface.
To have the entire cooking surface
warm, the damper will need to be in the closed position. This
funnels the heat under the entire cooking surface, therefore
heating it (see figure 10).
Figure 10

the combustion process it is at.

Oven Cooking
Learning how to most effectively control the oven temperature
takes some time and experience. As a general rule, the stove
should be at the charcoal stage of the combustion process
before the oven is ready for cooking.
Important Note: The oven door thermometer registers the
temperature at the door only. For accurate oven temperatures,
refer to this interior oven thermometer.

cooking from a cold start.
7. Always load a new charge of wood to a glowing hot coal
bed about 4” deep. Waiting too long to load a new charge
means that the dampers will have to opened, to get the
new charge burning well. This results in extreme
temperature swings and will make cooking difficult. Your
objective is to maintain the coal bed and a constant heat.
8. Occasional ‘tending’ or stirring may be required. Keeping
these principals in mind and with a little experience, you
will find cooking to be easy and trouble-free.
9. Woodstove cooking methods are as diverse as their
owners—there is no right or wrong way, only, in time, your
way.
Ovens vary in temperature from top to bottom and side to side.
The only accurate check on oven temperature is an oven
thermometer placed alonside food being roasted or baked.
See page 26 if your door thermometer needs adjustment.
1. You will find that once the stove has about 4” of red hot
coals in the firebox, it will have reached ‘equilibrium’.
2. Equilibrium means that the entire stove and chimney
system is heated and running at a fairly constant
temperature.
3.At this point, you may load a new charge of wood following
the procedure for ‘reloading’. Allow the stove to regain its
momentum—igniting the new charge. Keep bell dampers
dampered down to allow a steady slow flame.
4. The oven temperature can be controlled by moving the
oven damper slide. In the closed position, the oven will get
warmer, and cooler when you open it.
10. Remember by opening the oven damper there is less
resistance on the flue and a hotter faster fire will result. The
cooking surface directly over the firebox will typically get
hotter in this configuration.
11. Always open the oven damper before opening any firebox
doors or lifting the key plate. Wait momentarily before
opening the doors to allow the smoke in the oven chamber
to be drawn up the chimney to avoid backpuffing.
Maintain your stove properly. The benefits in superior
performance and safety are well worth the time.
Water Reservoir
This section pertains to the water holding tank on the side of
the stove and applies only to reservoir models .
5. Remember the effects of the changes in the damper
position are not instantaneous on the oven temperature.
6. Ideally your stove will perform best if it is left running
constantly, keeping the entire system warm. Depending
on your wood and chimney conditions it would typically
take three or four charges of cord wood to establish a good
base for oven cooking, meaning 1 1/2 to 2 hours before
The reservoir has a porcelain enamel top and lid. The lid lifts
open and will rest at an open position, or can be removed
entirely.
20
The tank in the reservoir is made of copper, for easy cleaning
and the seams are soldered with lead free solder.The tank has
a 5 gallon capacity with a spigot mounted on the side, for easy
access to the water.
Water must be added manually, the tank is not connected to
your plumbing.
To route heat around the reservoir, open the reservoir damper
(turn handle to the right). Vertical position of the handle means
that the reservoir damper is closed, and no heat is passing
under the copper tank. Horizontal position of the handle means
that the reservoir damper is open and more heat is circulating
under the copper tank.
The water in the reservoir can be heated from luke warm to
boiling hot depending on how you are burning the stove, the
position of the water reservoir and the oven dampers.
The reservoir damper is ‘downstream’ from the oven damper
which means that if the oven damper is open, the flu gases are
not circulating around the oven and therefore not past the
reservoir either, so the water in the reservoir will not get as hot
as when the oven damper closed.
The cold water will tend to absorb the heat that you are
attempting to use to heat the chimney to start the stove. Close
the reservoir damper during this period.
The same theory applies when heating the oven. If the water
reservoir damper is open, the valuable heat you are trying to
heat the oven with will be absorbed by the mass of cool water
in the reservoir. Close the water reservoir damper during this
period.
Woodstove heat is very dry and the water in the reservoir will
add much needed moisture to your home. The warm water can
be used for bathing, dishes or other clean up needs.
Always ensure water is in the tank when the stove is in
operation.
If the reservoir runs dry the soldering may melt
away from the joints, resulting in leakage.
Caution: The water reservoir is a naturally cooler area of your
stove, so creosote and fly ash will tend to build up on and
around that side of the stove. Because of the potential for
blockage and or ignition of the creosote,
frequent inspection
of this area is very critical and clean out must be performed
more often.
Helpful Hint: When lighting your stove from cold or when the
stove is relatively cool remember the water in the reservoir will
be at the same temperature.

Chimneys and Draft
T rouble Shooting
The performance of your woodburning system depends more
on the chimney than on any other single component. The
chimney ‘drives’ the system by producing the draft that
draws in combustion air and exhausts smoke and gases to
outdoors. Give as much attention to the chimney as you do
to the appliance that it serves.
How Chimneys Work
It is well known that hot air rises. This principle is at work
inside chimneys and is the key to understanding how
chimneys function.
The hot exhaust gases from the appliance are lighter than the
outside air. This buoyancy causes the gases to rise in the
chimney. As they rise, a slight negative pressure is created
inside the appliance. Air rushes into the appliance through
any available openings to balance this negative pressure.
The force caused by the rising gases is called draft. Draft is
created by the difference in temperature between the gases
in the chimney and the outside air. Greater temperature
differences produce stronger draft.
Factors That Affect Draft
There are several factors that interfere with draft and most
woodburning systems have one or more of these features. It
is usually a combination of conditions that make a chimney
fail to function properly.
Here are the main factors that influence draft:
poorly. Ideally, the liner should have the same internal area as
the flue collar of the appliance.
Chimney Height
Taller chimneys tend to produce stronger draft. We recommend
that the top of the chimney should be at least 36" (900 mm)
higher than the highest point at which it contacts the roof and
24" (600 mm) higher than any roofline or obstacle within a
horizontal distance of ten feet (three metres). These figures
produce the minimum allowable chimney height. Chimneys
higher than this are often needed for performance reasons. A
chimney serving a cookstove located on the main floor of a
single-storey house or cottage may not be tall enough to
perform well, even though the minimum heights in the building
code have been followed. A good rule of thumb to use states
that the top of the chimney should be at least 16 feet (4.9
metres) higher than the floor on which the cookstove sits.
Negative Pressure in the House
The draft produced by chimneys is a weak force that can be
influenced by pressures inside the house. A woodburning
cookstove acts as an exhaust ventilator by removing air for
combustion from the house. A typical house may have several
other exhausts, clothes dryer, gas or oil furnace, fireplace, or
central vacuum system. When one or more of these other
exhaust ventilators is running, it may compete for the same air
that the woodburning appliance needs for combustion. This
competition for air supply can make a fire slow to kindle or
cause a stove to smoke when its door is opened. Chimneys
are often blamed for this type of performance.
Cold Chimney Liner
An uninsulated chimney that runs up the outside of a house
and is exposed on three sides is chilled by outside cold. This
means that the flue gases give up their heat rapidly to the
liner. As they cool, they lose their buoyancy and draft is
reduced. Insulation between the liner and the chimney shell
can help to reduce the heat loss, but a chimney that is
enclosed within the house is preferable.
Large Liner
Chimney liners that are much larger than the flue collar of the
appliance allow flue gases to move too slowly. This slow
movement gives the gases more time to cool and lose their
buoyancy. Oversized liners are the reason that many fireplace
inserts vented through fireplace chimneys tend to perform
Stack Effect in houses
In winter, the air in houses is much warmer and, therefore,
more buoyant than the outside air. The warm air in the house
tends to rise, creating slightly negative pressure in the
basement and slightly positive pressure at higher levels. This
negative pressure in the basement can compete with chimney
draft to a stove or furnace located there.
CHECKING AN EXISTING CHIMNEY
Before an existing chimney is used to vent your new cookstove,
a thorough inspection should be done to determine its suitability.
The inspection should be performed by an experienced
professional because of the many factors that must be
considered. A reputable chimney sweep or retailer can give
you good advice on the suitability of an existing chimney.
22
Masonry chimneys should be checked for deterioration
including damaged bricks, crumbling and missing mortar,
cracks in the drip cap at the top of the chimney, and loose
flashings at the roof line. The liner should be checked for
cracks and mis-alignment, and its size should be 6".
An existing factory-built metal chimney needs a careful
inspection. Your new cookstove should be connected only to
factory-built chimneys approved to ULC Standard S629 in
Canada and UL 103HT in the U.S. Possible problems with an
older metal chimney can include a warped or buckled liner
caused by the heat of a chimney fire, corrosion of the outer
shell, a loose flashing, and a lack of proper support. Any
discolouration of the metal shell near a joint indicates that the
insulation has settled. A damaged metal chimney should be
replaced with a new approved chimney which will be safer and
will perform better.
Safety Practices
What To Do If You Have a Chimney Fire
Here is a checklist to follow when installing or checking a flue
pipe assembly. It is based on the requirements found in the
Canadian Standards Association’s Installation Code for Solid
Fuel Burning Appliances and Equipment (Standard B365).
1) Single-wall flue pipe assemblies must not exceed
3 metres (10' ) in overall length.
2) The assembly should be as short and direct as possible.
3) A single-wall flue pipe assembly must have no more than
two 90 degree elbows; use 45 degree elbow, wherever
possible.
4) Do not use galvanized flue pipe because the coating can
vaporize at high temperatures, emitting poisonous gases
and leaving the pipe thin and weak.
5) Flue pipes for woodburning appliances need to be thicker
than those used for other fire-burning appliances; 24
gauge for 150 mm (6") .
6) Joints between pipes should overlap at least 30mm
(1 1/4").
7) Each joint should be secured with three sheet metal
screws.
1) Close all the combustion air dampers on the appliance.
2)
Call the fire department immediately.
3) Be prepared to get everyone out of the house in case the
fire spreads
4) Go outside and check to see that hot ashes do not ignite
shingles.
5) Watch anything near the chimney that could catch fire and
burn.
6) After the fire has run its course and the chimney has
cooled,
have the chimney thoroughly inspected to
determine if it sustained any damage.
7) Resolve to inspect and clean the chimney more often to
prevent another chimney fire.
Flue Pipes
Flue pipes carry the exhaust gases from the appliance flue
collar to the chimney. The flue pipe assembly is an extremely
important part of a woodburning systems and should be
carefully planned and installed.
8) The assembly should be constructed to allow for expansion.
Elbows in an assembly allow it to expand; straight flue
pipe assemblies should have one section left unscrewed
and secured with an inspection wrap clamped around the
joint.
9) The pipes should slope up towards the chimney at least
20 mm/metre (1/4 in/ft).
10) One end of the flue pipe assembly must be securely
fastened to the flue collar of the appliance and the other
end fastened to the chimney.
11) There must be provision for the cleaning and inspection of
the pipes by removal of the pipe. The removal of the pipes
should not require moving the appliance.
12) The crimped ends of the pipes should point towards the
appliance so that condensation drains to the appliance
and does not leak out.
13) A flue pipe must never pass through a combustible floor or
ceiling, or through a concealed attic, roof space, or closet.
Flue pipe assemblies should be stable and secure. To check
the stability of a flue pipe assembly, grasp it at its mid-point
and give it a good shake. If it is properly constructed, it will have
little or no movement.
23
Maintenance
Oven Flue Passage
As heat, smoke and gases travel around the oven, fly ash and often creosote are left behind. The frequency of cleaning of the
oven flue will depend on your use, burning habits and the wood you burn. If a ‘fly ash’ which is very fine and light in colour, is
what is left behind in the oven flue chamber, it is a good indication you are burning your stove well.
If a sticky black ash is what you observe, you are burning wood which is too wet or the stove is not burning hot enough as a
result of a poor chimney. Your dealer can help you correct this.
Follow this procedure when cleaning around the flue passage:
1) Clean the oven flue chamber by removing the top lids and scraping the ash to the sides.
2) Then scrape the sides so the ash falls to the bottom.
3) All the ash may then be scraped into a metal container through the ash cleanout door with the ash scraper.
4) Follow the procedure for ash disposal when cleaning the oven flue chamber, and chimney connector system.
Creosote buildup in the oven flue chamber can lead to rusting, a bad odour, and chimney fires. Check for creosote regularly and
clean it out upon discovery.Caution: The water reservoir is a naturally cooler area of your stove, so creosote and fly ash will
tend to build up on and around that side of the stove. Because of the potential for blockage and or ignition of the creosote,
inspection of this area is very critical and clean out must be performed more often.
Creosote is a tell tale condition of burning wet wood, a practice which should immediately be discontinued.

Flue Boot Inspection
Remove the cover plate on the flue boot, located at the back
of the range. Inspect for soot or creosote buildup, scrape and
clean as much as possible, and remove debris through the
clean out door with the ash scraper.
Oven Damper
The oven damper may stick from time to time because of a
buildup of ashes or creosote in the damper track. To free up the
damper, scrape out the buildup or spray with a creosote
remover, let sit for about 1/2 hour and clean out debris.
(Caution: Never use any remover or cleaner on a hot stove.)
Chimney Maintenance
Chimney serving woodburning appliances must be checked
regularly for creosote build-up. The rate of build-up depends
cookstove and chimney characteristics, the type of fuel used,
and on how the system is operated.
Until you are familiar with the rate of creosote build-up in the
system, check it often - every couple of weeks. Well-designed
woodburning systems tend to have a slower rate of build-up in
the spring and fall when heat demand, and therefore firing rate,
is lower.
the condition of the chimney. Referrals are the best way to
select a chimney sweep. Check with your neighbours to see
if they are satisfied with the sweeping services they have
received.
Cooking Surface
After the initial firing, your stove top will start to turn colour. This
is normal and eventually the stove top will have a uniform blue
finish.
The stove tops and lids are highly polished untreated cast iron.
To minimize the potential for permanent stains, always
maintain the top with cooking oil. During periods of
heavy use, a light coating is sufficient. When you will not
be using the stove for a week or more, give the top a
heavier coat and re-apply as needed. Always remove
food, water or rust stains as quickly as possible. If such
stains are left unattended, a permanent mark can result.
To help remove stains, use a medium/fine aluminum
oxide abrasive sanding block, available at most
hardware stores, or a metal cleaner such as Flitz, in
conjunction with fine (000) steel wool. Do not be afraid
to use elbow grease.
Creosote may be in the form of dry, flaky deposits clinging to
the liner, or a shiny, glazed coating that looks like black paint.
Glazed creosote is the most dangerous kind and indicates
that one or a combination of conditions exist in the system
that can cause the deposits.;
1) a cold liner
2) smouldering fires
3) wet wood
Glazed creosote should never be allowed to exceed 1/8"(3 mm
) in thickness, Dry, flaky creosote should be removed when it
reaches 6 mm (1/4") in thickness.
Chimney Cleaning Equipment
Brushes and rods are the most common chimney cleaning
equipment. Plastic brushes are normally used in metal
chimneys and steel brushes are used for masonry chimney.
The brush should fit snugly in the chimney so that enough
friction is produced to remove deposits. Most chimney cleaning
rods are made from fibreglass with threaded couplings at each
end. Several passes with the brush are needed for a thorough
cleaning.
Many homeowners prefer to contact the services of a chimney
sweep rather than climbing on their roofs to clean the chimney.
An experienced chimney sweep can complete the job quickly
and will leave no mess behind. The sweep will also report on
Stove top and/or keyplate may expand during heating and
use - this is normal and slight gaps may appear around key
plate. The natural expansion and contraction of the
keyplate during heating is not unusual.
At the end of the heating season, especially in a seasonal
location, apply a coat of cooking oil to keep the top from
rusting.

Nickel Trim
Nickel trim may be cleaned with any non-abrasive metal polish
and a soft cloth.
Porcelain
Never clean porcelain while the stove is hot. Porcelain is glass
and sudden changes in temperature may cause cracking.
Clean porcelain surfaces with glass cleaner or polish and a soft
cloth. Oven stains may be removed with household oven
cleaner.
Please Note: The spilling of acids like vinegar or lemon juice
on the porcelained reservoir could leave a permanent stain.

Door Gaskets
Oven Thermometer Adjustment
The rope gasket around the oven door, firedoor, ash pan door
and ash door flap, should be periodically inspected for a good
seal.
If the gasket comes loose but is still usable, it can be reseated
using a good high temperature silicon. Replacement gasketing
and adhesive can be ordered from Heartland or your dealer.
Gasketing is sold by the foot. Refer to the gasket listing below.

temperatures, refer to the interior oven thermometer.
An adjustment can be made to the oven door thermometer
to allow a more representative temperature reading (most
thermometers are adjusted to provide accurate readings in
the 300F to 400F temperature range). After the
adjustment, the low and high end of the temperature
spectrum will not be accurate. To make temperature
adjustments please follow the instructions below:
1) Begin by removing the screws on the inside oven door
panel. Remove panel.
2) The back of the thermometer is exposed ready for
adjustment.(see figure 11)
3) With fine nose pliers, adjust the “L” bracket of the
thermometer, moving indicator needle to desired position.
4) Replace the oven door panel and screws.
5) Re-test thermometer and adjust again if necessary
For accurate oven
Firebox
Periodic cleaning and inspection of the firebox is recommended.
On the SweetHeart and Oval cookstove there is a gasket on
the top under the keyplate. This gasket should be inspected
and replaced if it fails to seal.
Check for condition of side castings (Oval only) and smooth
operation of wood grate.
Some cracking of the firebrick is normal and may be sealed
with stove cement.
The firebrick, grate and cast liners are replaceable parts. You
will prolong the life of these parts by:
1. Following the procedure for break in fires;
2. Avoiding impacting these parts when loading firewood;
3.Burning seasoned firewood.

Formula for Equivalent Hearth Extension
Hearth extension may be fabricated from non-combustible
materials as long as the materials are at least 1/2" thick and
have a thermal conductivitey factor "K" of 0.43 or lower.
Formula: Units of K = btu/ft/h/F/in
Example for determining thickness of equivalent material:
("K" of equivalent material)x 0.5 = thickness required
.043
The thermal conductivity of "K" of equivalent material can
usually be obtained from the manufacturer of the material.

Terms of Reference and Function
Backpuffing—The momentary emission of smoke through
openings in the stove when oxygen is admitted to an oxygenstarved fire. When a door or the bell dampers are opened, the
sudden charge of air may not be immediately absorbed by the
chimney system, resulting in a backpuff of smoke.
To help eliminate this problem ensure that the oven damper is
open before opening the ash pan or firedoor. Open the doors
slowly to allow the smoke to clear from the chimney system.
Warming Cabinet—The storage and warming area mounted
to the base of the stove. Provides overhead storage and
warming for plates and foods. May also be referred to as
warming closet.
Oven Damper—The shutoff for routing the heat smoke and
gases either directly out through the flue or around the oven.
When ‘open’ the smoke, heat and gases will exhaust directly
out the flue. This is the position used during the initial firing of
the stove.
When ‘closed’ the smoke, heat and gases will be routed
around the oven heating the oven, cooking surface and more
of the stove mass. When the oven damper is ‘closed’ more
resistance is put on the chimney system.
Opening any doors or lifting the key plate with the oven damper
closed will result in backpuffing. Always open the oven damper
before opening the ash pan door, firedoor or key plate.
Oven Flue Passage—The air space around the oven (between
the oven top and the cooking surface, the right side of the oven
and the right side of the stove, and the bottom of the stove and
bottom of the oven) through which heat, smoke and gases
travel.
This resulting travel heats the oven when the oven damper is
in the ‘closed’ position.
Backdrafting—The emission of smoke and/or air through the
stove when a flow reversal occurs in the chimney, caused by
wind conditions or negative pressure within the building.
Bank (the fire)—Loading the firebox with fuel (wood or coal)
to produce a long burn cycle. Banking can only be
accomplished on a good bed of coals.
Key Plate—The cast iron section on the stove top which is
lifted for fuel loading or to make repairs in the firebox.
Key Plate Lift Handle—The handle used to lift the key plate
to allow access to load the firebox.
Lid—The removable round cast iron disks on the stove top.
Can be removed to allow access to clean the flue chamber
above the oven.
Lid Lifter—The tool used to remove the lids, open and close
the firebox doors, and adjust the bell and oven dampers (see
figure 8).
Oven Rake—The tool used to scrape creosote and ash from
the flue chamber around the oven.
Oven Cleanout Door—The door under the oven that is
removable to allow access to scrape ashes out of the flue
passage around the oven.
Water Reservoir—The water holding tank on the side of the
stove. Water must be added manually. The tank is not
connected to your plumbing.
Woodstove heat is very dry and the water in the reservoir will
add much needed moisture to your home. The warm water can
be used for dishes and other clean up needs.
Water Jacket—A hollow collector which is installed in the
firebox through which water flows is heated and is circulated
to a storage tank, either by convection flow or by a small pump.
This system may be used for domestic hot water or baseboard
heating. Installation should be carried out only by a qualified
plumber. Ask your dealer, or call or write us for an installation
guide.
Creosote—When wood is burned slowly, it produces tar and
organic vapours, which combine with expelled moisture to
form creosote.
Creosote vapours condense in the relatively cool chimney flue
of a slow burning fire resulting in creosote residue accumulating
on the flue lining. When ignited, this creosote makes an
extremely hot fire.
Establish a routine for the fuel, wood burning and firing
technique.
Check daily for creosote buildup in the pipe and chimney until
experience shows how often you need to clean to be safe.
The hotter the fire and/or the drier the wood, the less creosote
is deposited. We recommend burning your stove with all the
combustion air dampers open for at least an hour each day.
Weekly cleanings may be necessary in mild weather; monthly
cleanings may be enough in the coldest months.
27
Overfiring — Caution!
Overfiring of your woodburning appliance represents a serious fire hazard.
Overfiring can also warp your stove, break welds, permanently discolour the
plating and cause premature burnout of your stove. Repeated overfirings will
void the warranty of this appliance
To prevent overfiring:
1. If the air intake has little effect on dampering the fire, excessive chimney draft is
the probable cause (especially on chimneys in excess of 20’). Normal chimney
draft is approximately 0.05". Install a smoke pipe damper in the pipe approximately
5’ from the floor. NOTE: Open damper before opening door to prevent smoking.
2. Install a magnetic thermometer on the top of your stove near the flue collar or a
probe-type thermometer in the smoke pipe.
To prevent creosote buildup in the pipes, the stove should be run between 800°F
and 900°F for 30-45 minutes each burning day.
.
3.Except for the initial period after lighting (5-10 minutes), do not operate your stove
with the door open.
4. Ensure the ash pan door is tightly closed during operation. An open ash pan door
will allow excess draft through the firebox, causing overfiring. When emptying
ashes, clean thoroughly behind the ash pan to allow complete closure.
5. Clean your chimney regularly to remove creosote buildup. A chimney fire is a fire
hazard and will overfire your stove. See page 23, "What to do if you have a
chimney fire"
6. During operation, if any parts of the stove or pipe begin to glow the stove is
overfired. Do not add fuel. Close all doors, dampers and draft controls completely
until glowing is eliminated and safe temperatures are restored. If overfiring
conditions persist on subsequent burnings, contact your dealer for remedial
action.
