Warning: Thestove is very heavy. Sincethebody frame may
diginto a softfloor,do notlocatethe stove,oreven set itto 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.
Thebase assembly should beassembled and inpositionprior
tolifting thestove offof theskid; thebase assemblyinstructions
followbelow.
BaseAssembly(Sweetheartonly)
1. Unpackagethebasesections,legs andhardwarepackage
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. Screwthe base levellingbolts(with teflon glider attached)
intoeachof the four legs.Thelevelling bolts are locatedin
thehardware package. Wheninstalling the levellingbolts,
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
glidersandfloor are freeofany debris, this willensureyou
do not scratch your floor.

Gas,Electric,Combination and Wood Stoves" which is
included in the cabinet box.
Once the cabinet has been assembled and installed, follow
these few remaining steps:
1. Insert the lift handle( #1361) through the bracket and bolt
it through the hole in the cooking surface with the screw
and locknut.
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. Thethree 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.
Thedamperinstallationshouldbedonebeforefinalassembly
of the chimney.
a) Open the front cabinet door.
b) Mark the spot for drilling in the back of the pipe by
pushingthe sharp endof the damperrodinto thebackwall
of the pipe before drilling.
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.

Installation
Be sure to read the sections on clearances, floor protection
andchimneys beforeactivelystarting theinstallation. Contact
local building or fire officials about restrictions and
installation in your area.
Clearances
A woodburning stove radiates heat in all directions. Heat
directedtowardliving areas in front ofthestoveis 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
notoverheat.
The clearance distance should be empty except for non-
combustible heat shields.
Air flowing between the stove and stovepipe and nearby
surfaces carries away heat.
(continued on page 10)
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 of
Clearances"andpage12"FreshAirKit"for moreinformation
Be aware that as wood is exposed to continuous heat it dries
out,eventually loweringthetemperature atwhichit willstarton
fire.
Maintain the clearances outlined in this manual, particularly
with respect to nearby combustable surfaces.
YourHeartlandcookstovehasbeen 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.

for our woodstoves for reduced
clearances. See page 11 on "Heat

Dimensions A, C, G, and H remain the same with or with-out a heat shield.
Dimensions A and C are taken from the reservoir on reservoir models.
When two or more clerances to combustible walls contradict each other,
the clearance with the greater numerical value must be maintained.

Figure 3
Illustration showing minimum heights required,
depending on the locaton of chimney
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
chimneywhichis in compliance withtheappropriate standard
or a prefabricated chimney approvedto ULCStandardS629
in Canada and UL 103HT in the U.S.
Followthechimneymanufacturer’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.
Thechimneyand installation will have tobeinspected by your
local building inspector.
Recommended Chimney Clearances
The chimney must: (see figure 3 below)
•extend at least 14 ft. above the collar of the stove;
•extend at least 3 ft. above the point where it passes
throughtheroof;
•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
foryou).
24" (600mm)
10'
(3 metres)
36" (900 mm)
Clearance Reductions
There are many alternate decorative methods to reduce
clearancesto combustible materials. Seeyour dealer, or local
fireorbuilding official to ensure theappropriatestandardsare
being met with these alternatives. In Canada, refer to the
Installation Code for Solid Fuel Appliances and
Equipment.CAN3-B365-M84.IntheU.S.,refertotheNational
Fire Protection Association Standard 211,
Floor Protection
When installing this cookstove on a combustible floor, a
noncombustiblefloorprotectorisrequiredunderthestove.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
extend450mm (18") beyond any side with aloadingdoor and
200 mm (8") beyond the other sides and rear. (See page 7
"OvalRough-inDimensionDiagram"or page8"SweetHeart
Rough-inDimensionDiagram".)Floorpadsmaybefabricated
from non-combustible materials. (see page 26 "Formulafor
Equivalent Hearth Extension")
Chimneys and Draft
The chimney is the most important element of successful
stove operation. (see also page 23 "Flue Pipes")
Performanceofyourwoodburningsystemdependsmore
on the chimney than on any other single component.

Fresh Air Kit
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
draftingproblems.
Duringthe heating season,coldair, (whichismore densethan
warm air), will cause the fire to burn a little hotter, resulting in
more BTU’s from your wood, and less creosote build-up.
Installation is Easy
Mounting holes and airways are all pre-punched on all new
OvalandSweetheartcookstoves.(see figure 5)
Simplyremovethecoverplates (rightsideoffireboxon theOval
and,bottomof the firebox on Sweetheart). Nowyouareready
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 canreduceor virtuallyeliminateyour hotwater
utility bill.
Installation is Easy
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.)
Youcan expect from8to 10 gallonsor more hotwaterper 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.

Charcoal: As the fire progresses
andmostofthegaseshavevaporized,
charcoalremains.Charcoalisalmost
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
ofthe wood you burn,about half is in
the form of smoke, and half is
charcoal.
Water: Up to half the weight of
freshlycut logsis 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.
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
overallefficiency by burningfirewood that hasbeen split, stackedand air-dried undercoverfrom rain forat least oneyear. 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.
figure 7
Understanding Combustion
Smoke(or flame): Asthe woodheats
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 brightflamesthat
arecharacteristic ofawood fire.Ifthe
smokedoes notburn, itwill condense
in the chimney forming creosote or
exit the chimney as air pollution.

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
recommendedasanythingin 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
Goodsafetypractices:
Educate your family members:
•before burning the stove, have each family member read
this manual and be aware of safety practices;
•keepchildren,clothing and furniture awayfromthestove;
•thestove is HOTwhile in operation–DONOT TOUCHthe
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)
•keep a fire extinguisher nearby and have a clearly
understood plan on how to extinguish a fire.

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.
Understandingthe primary principlesof the airintake controls,
theoven damper,the flamepath forthe fireand therelationship
tothechimneywillgiveyouaverycomprehensiveunderstanding
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
overthehook and pulling towardsyou.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
castironliners, these linersreston an oval refractoryfirebrick.
IntheSweetheart, looking into the fireboxthroughthe top you
willsee firebrickliners onthe leftandright 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—
slideit back andforthand looking downintothe firebox youwill
see the slots open and close.
The stove is burned with the slots open which allows the
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)
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.Alittle extra care and thoughtfulness during thebreak-
in period will help promote a long life for your stove.
Thecastiron and firebrick will have pickedupmoistureduring
shippingandstorage.
Duringthe break-in perioditis important toletthe cast ironand
firebrick slowly dry out and avoid thermal shock, caused by
strong hot fires.
•Buildasmall kindling fire (followingtheinstructions 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.
•Repeatthe processfora fewdaysor untilyouhave hadsix
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.
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
toopenthe ash door slightly untilagood 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.
Lighting the ‘charge’is of your personal preference. One
methodisto roll a pieceofnewspaper into a torch,lighting
one end and using it to start the paper.
Lightthepaperatthebottom of the load and then light the
paperatthetop, shut the key plate immediately. Youmay
findithelps to hold thekeyplate open just slightlyfora few
seconds to give some extra air and establish the fire.
3. ToFuel the Fire. Afteracouple of minutes lift thekeyplate
oropenthe front loading doorslowly.Whenthe 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.
Thesmoke and heatisnow beingroutedaround 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.

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 piecesof wood in thenew
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.
The stove must rebuild its thermal momentum before
closing the oven damper.

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.
Theminimumdraftrequiredto maintain an oven temperature
of350 ºf isaround .04"on awater column.Fordraftsunder.04"
on a water column, closing the oven draft damper more than
half way, will cause back puffing.
Duringthe rechargephaseof anewbank, adraft 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/
8indiameter. However, other coal, such asbitumious,canbe
burned, but is inferior to anthracite.
To Start a Coal Fire:
1. Use paper and dry wood kindling to start the fire.
2. Addsmall, compactpiecesof hardwoodwhenthe kindling
is burning hot. Keep the primary damper controls fully
open to establish a hot fire quickly.
