CLEARANCES TO COMBUSTIBLES
Floor protector must be 3/8 (10mm) thick minimum
noncombustible material or equivalent, extending
beneath heater and to the front/sides/rear as indicated
in the Floor Protection (See Figure 5).
Note 1: 6" (152mm) diameter single wall, minimum
24 MSG black or blued steel connector pipe with a
listed factory-built type HT chimney suitable for use
with solid fuels or a masonry chimney.
Note 2: 6" (152mm) diameter double wall air cooled
connector pipe with listed factory-built type HT chim-
ney or a masonry chimney. (Mobile home venting sys-
tem must be equipped with a rain cap and spark ar-
restor.) For installations with a preexisting class A
chimney system, a listed stainless steel chimney liner
should be installed, or the existing chimney exam-
ined by a chimney sweep for acceptable further use.
Note 3: Alcove specifications: Maximum depth of al-
cove shall be no more than 48" (1219mm). For addi-
tional alcove information and clearances, refer to
clearances to combustibles above.
NOTE: Unit is approved for use with listed double wall
air-insulated chimney connector or elbows.
When locating your stove consider safety, conve-
nience, traffic flow, and the fact that the stove will need
a chimney and chimney connector.
NFPA 211: Use a noncombustible material with 1
(25mm) ventilated air space to reduce clearances.
However, this is not to exceed 50% of WS-150s (or
WS-250s) specified clearances.
NOTE: Must follow NFPA 211 spacing and materials
to qualify. It is also subject to local jurisdiction.
AVOID FIRE: Maintain the designated clearances to
combustibles. Insulation must not touch the chimney.
You must maintain the designated air space clear-
ance around the chimney. This space around a chim-
ney is necessary to allow natural heat removal from
the area. Insulation in this space will cause a heat
buildup, which may ignite wood framing.

SAFETY LISTING
The WS-150 AND WS-250 are approved for mobile
home installations with outside combustion air in the
U.S. (See page 14 for further details). For residential
installations in Canada without an outside combus-
tion air kit, a source of fresh air into the room must be
provided.
INSTALLATION MATERIALS NEEDED
FOR YOUR SAFETY
CHIMNEY CONNECTOR (also known as flue pipe
or stove pipe): The chimney connector joins the stove
to the chimney (see page 11). It should be 6" (152mm)
minimum diameter 24 MSG black or blued steel, or
an approved air-insulated double wall venting pipe.
THIMBLE: A manufactured or site-constructed
device installed in combustible walls through
which the chimney connector passes to the chim-
ney (see pages 11-12). It is intended to keep the
walls from igniting.
CHIMNEY SYSTEMS
A. APPROVED MASONRY (see specifications on
pages 12-13) with at least 5/8" (16mm) fire clay
lining joined with refractory cement or other listed
system suitable for use with wood stoves.
B. PREFABRICATED 6" (152mm) listed high tem-
perature (UL 103HT or ULC 629M) chimney. Com-
ponents required by manufacturers for installa-
tion such as the chimney support base, firestop
(as appropriate), attic insulation shield, insulated
tee, etc., are necessary to assure a safe chim-
ney installation. Use only components manufac-
tured for the chimney. Chimney installation should
meet NFPA 211 standards.
FIRE SAFETY: To provide reasonable fire safety, the
following should be given serious consideration:
1. Install at least one smoke detector on each floor
of your home to ensure your safety. They should
be located away from the heating appliance and
close to the sleeping areas. Follow the smoke
detector manufacturers placement and installa-
tion instructions, and be sure to maintain regularly.
2. A conveniently located Class A fire extinguisher
to contend with small fires resulting from burning
embers.
3. A practiced evacuation plan, consisting of at least
two escape routes.
4. A plan to deal with a chimney fire as follows: In
the event of a chimney fire:
A. Notify fire department
B. Prepare occupants for immediate evacuation.
C. Close all openings into the stove.
D. While awaiting fire department, watch for ig-
nition of adjacent combustibles from over-
heated stove pipe, hot embers or sparks
from the chimney.
VENTING SYSTEM
The venting system consists of a chimney connector
and a chimney. These get extremely hot during use.
In the event of a creosote fire, temperatures inside
the chimney may exceed 2000°F (1100°C). To pro-
tect against the possibility of a house fire, the chim-
ney connector and chimney must be properly installed
and maintained. An approved thimble must be used
when a connection is made through a combustible
wall to a chimney. A chimney support package must
be used when a connection is made through the ceil-
ing to a prefabricated chimney. These accessories
are absolutely necessary to provide safe clearances
to combustible wall and ceiling material. Follow vent-
ing manufacturers clearances when installing vent-
ing system.
This stove may be connected to a lined masonry
chimney or a listed high temperature prefabricated
approved metal chimney. Do not connect it to a chim-
ney serving another appliance. To do so will affect the
safe operation of both appliances.

CHIMNEY CONNECTOR
The chimney connector must be 6" (152mm) diam-
eter with a minimum thickness of 24 gauge. Do not
use aluminum or galvanized steel. They cannot prop-
erly withstand the extreme temperatures of a wood
fire. Do not use chimney connector pipe as a chim-
ney. You must connect your stove to a chimney com-
parable to those illustrated in this manual.
Chimney connector sections must be attached to the
stove and to each other with the crimped end toward
the stove (see Figure 6). This allows creosote to run
into the stove and not onto the outside of the pipe.
Attach the chimney connector to the flue collar with
three sheet metal screws. All joints should also be
secured with three sheet metal screws. Otherwise,
in the event of a creosote fire, the connector may vi-
brate apart.
For proper operation, the chimney connector should
be as short as possible. Horizontal lengths of chimney
connector should have a minimum upward slope from
the stove of at least ¼" per foot.
CHIMNEY HEIGHT/DRAFT
To insure that the stove burns properly, the chimney
draft (static pressure) should be approximately 0.1"
water column (W.C.) during a high burn and .04" W.C.
during a low burn, measured 6" (152mm) above the
top of the stove after one hour of operation at each
burn setting.
NOTE: These are guidelines only, and may vary
somewhat for individual installations.
This stove was designed for and tested on a 6"
(152mm) chimney, 12'-14' (3.66-4.27m) high,
FIGURE 6
measured from the top of the stove. The further your
stack height or diameter varies from this configuration,
the probability of performance problems increases.
In addition, exterior conditions such as roof line,
surrounding trees, prevailing winds and nearby hills
can influence stove performance.
CONNECTION TO A MASONRY
CHIMNEY
1. CHIMNEY:
Should the stove be connected to a masonry
chimney, the chimney should be examined for cracks,
loose mortar, or other signs of deterioration and
blockage. The stove should not be installed until it is
determined that the chimney is safe for use. Since
an oversized flue contributes to the accumulation of
creosote, the size of the flue should be checked to
determine that it is not too large for the stove. The
chimney should also be checked to insure it meets
the minimum standards of the National Fire Protection
Association (NFPA) Standard 211. Following is a list
of the more critical minimum requirements for a
properly constructed chimney.
The masonry wall of the chimney, if brick or modular
block, must be a minimum of 4" (102mm) thick. A
mountain or rubble stone wall must be at least 12"
(305mm) thick.
The chimney must have a fire clay flue liner (or
equivalent) with a minimum thickness of 5/8" (16mm)
and must be installed with refractory mortar. There
must be at least ½ " (13mm) air space between the
flue liner and the chimney wall (see Figure 7). An
equivalent liner must be a listed chimney liner system
or other approved material.
FIGURE 7

9
A chimney inside the house must have at least 2"
(50mm) of clearance to the combustible structure.
A chimney outside the house must have at least 1"
(25mm) clearance to the combustible structure.
Firestops must be installed in the spaces where
the chimney passes through floors and/or ceiling
(Figure 8).
FIGURE 8
Minimum 1
Clearance for
Exterior Chimney
to Sheathing
Remember that insulation must not contact the
chimney. There must be air space around the
chimney. Insulation must be 2" (50mm) or more from
the chimney (Figure 9).
A chimney must be the required height above the
roof or other obstruction for safety and proper draft
operation. The chimney must be a minimum of 3'
(914mm) higher than the highest point where it
passes through the roof, and at least 2' (610mm)
higher than the highest part of the roof or structure
that is within 10' (3048mm) of the chimney, mea-
sured horizontally (Figure 10).

2. THIMBLE:
An approved thimble must be used
when the connection from the stove is
made through a combustible wall to a
masonry chimney. There are several
methods you can use for connection
through a combustible wall, two of
which are illustrated in this manual. For
additional methods, consult local build-
ing authorities or use the standards set
forth in NFPA 211.
Also, listed prefabricated metal
thimbles are available for use with
wood stoves. The manufacturers in-
stallation for the thimbles must be
strictly followed to assure the safety of
the system. Be sure to maintain the
designated clearances to combustible
materials.
A. BRICK CHIMNEY THIMBLE
ASSEMBLY:
Construction of the brick thimble as-
sembly requires 12" (305mm) of
brick around a fire clay liner. Be sure
the point of penetration allows an 18"
FIGURE 11
Chimney
Wall
(457mm) clearance from the connector to the ceil-
ing. For a 6" (152mm) chimney connector, an open-
ing of 30" (762mm) must be cut in the wall to main-
tain the required 12" (305mm) of brick separation
from combustibles. It will be necessary to cut wall
studs and install a header and sill frame to main-
tain proper dimensions and to hold the weight of
the brick (Figure 11).
fire-parts.com

11
Minimum 3 ½" (89mm) [4" (102mm) nominal] thick
solid bricks are to be used. The fire clay liner (ASTM
C35 or equivalent), 5/8" (16mm) wall thickness, must
not penetrate into the chimney beyond the inner
surface of the chimney flue liner and must be firmly
cemented in place. If it is necessary to cut a hole in
the chimney liner, use extreme care to keep it from
shattering. Refractory mortar must be used at the
junction with the chimney liner. After the assembly is
complete, insert the chimney connector into the fire
clay liner. Do not push it beyond the inside edge of
the chimney liner, as this will affect the draw of the
chimney.
B. 6" SOLID PACK CHIMNEY WITH METAL
SUPPORTS AS A THIMBLE:
For the method of installation to a masonry chimney
shown in Figures 13 and 14 , it will be necessary to
purchase a 6" (152mm) inside diameter, 12" (305mm)
long section of prefabricated listed solid pack chim-
INSTALLATION USING MASONRY
OR BRICK CHIMNEY
FIGURE 12
ney to use as a thimble. Purchase a wall
spacer, trim collar and wall band that
are manufactured to fit the chimney
section you purchase. Cut out a 14 ½"
(368mm) diameter opening in the wall.
It may be necessary to cut wall studs
and install a header and sill frame to
maintain the wall support. The hole in
the chimney must have at least a 6"
(152mm) diameter fire clay liner or
equivalent, secured with refractory mor-
tar. If it is necessary to cut a hole in the
chimney liner, use extreme care to keep
it from shattering.
The safety features of this system are
the 2" (50mm) air space between the
chimney section and combustible wall
and the 1" (25mm) air space around the
chimney connector as it passes through
the chimney section to the chimney. The
location of the opening through the wall
to the chimney must leave a minimum
18" (457mm) vertical clearance be-
tween the connector pipe and the ceil-
ing, to prevent the ceiling from catching
fire when using single wall pipe.
First, build the frame for the thimble,
making sure that it is no smaller than
14½" (368mm) diameter, which will
maintain a 2" (50mm) air space around
the chimney section. Attach the wall
spacer to the chimney side of the frame. Then insert
the frame into the opening, toe-nailing it to the wall
studs. Install the wall band in the framing to secure
the chimney section in place. Insert a single section
of chimney connector into the chimney through the
wall band, being sure it does not protrude into the
chimney beyond the edge of the chimney flue lining.
Apply high temperature furnace cement to the end of
the chimney section and install it over the connector,
through the wall band, and through the wall spacer.
Tighten the wall band to hold the chimney section firmly
in place and against the chimney. Install the trim col-
lar on the outside of the opening.
Check to insure there is a 1" (25mm) air space be-
tween the connector and the chimney section. Also,
during installation, always check to insure that a 2"
(50mm) air space is being maintained to the wood
framing. Do not fill this space with insulation. Insula-
tion in this air space will cause a heat buildup which
may ignite the wood framing.

When a metal prefabricated chim-
ney is used, the manufacturers in-
stallation instructions must be fol-
lowed precisely. You must also pur-
chase (from the same manufac-
turer) and install the ceiling support
package or wall pass-through and
T section package, firestops
(where needed), insulation shield,
roof flashing, chimney cap, etc.
Maintain the proper clearance to the
structure as recommended by the
manufacturer. This clearance is usu-
ally a minimum of 2" (50mm), al-
though it may vary by manufacturer
or for certain components.
There are basically two methods of
metal chimney installation. One
method is to install the chimney in-
side the residence through the ceil-
ing and the roof (Figure 15). The
other method is to install an exterior
chimney that runs up the outside of
the residence (Figure 16). This
method of installation requires at a
minimum a wall pass-through de-
vice, a wall support package, insu-
lated T section and roof flashing.
The components illustrated may not
look exactly like the system you pur-
chase, but they demonstrate the ba-
sic components you will need for a
proper and safe installation.
The chimney must be the required
height above the roof or other ob-
struction for safety and proper draft
operation. The chimney must be a
minimum of 3' (914mm) higher than
the highest point where it passes
through the roof, and at least 2'
(610mm) higher than the highest
part of the roof or structure that is
within 10' (3048mm) of the chimney,
measured horizontally (Figure 10).
REMEMBER: Follow the manu-
facturers installation instructions
and maintain the manufacturers
specified clearance distances.

OPERATING AND CLEANING
CAUTION: DO NOT operate stove with ash
removal system door open. Ensure that embers
have cooled completely before removing ash.
1. When stove is cool, open front door and
brush most of the ash into the center of
the firebox. Remember to leave 1/4 to
1/2 (6-13mm) of ash on the firebox floor
to act as a natural grate, allowing air to
flow freely underneath wood .
2. Clean ash down through the ash re-
moval system grate into the drawer be-
low. If there are large pieces in the ashes,
you can remove the grate before clean-
ing the ash into the drawer. Be sure to
replace the grate before operating the
stove.
3. Release latch on side of ash removal
door (see Figure 23).
4. Pull out the ash drawer. Close ash removal door.
(Closing this door avoids ash blowing into the room
in the event of a downdraft.)
5. Empty ashes into metal container. Store container
on non-combustible surface until ashes are cool
enough to dispose.
6. Open ash removal door and replace ash drawer,
making sure handle faces forward.
7. Close ash removal door and fasten latch.

BURNING PROCESS
In recent years there has been an increasing con-
cern about the quality of our air. Much of the blame
for poor air quality has been placed on the burning of
wood for home heating. In order to improve the situa-
tion, we at Heat-N-Glo have developed cleaner burn-
ing wood stoves that surpass the stringent require-
ments for emissions established by our governing
agencies.
Properly operated and maintained your WS-150 or
WS-250 wood stove will obtain the peak efficiency
and lowest emissions possible, resulting in better air
quality for your community and more heat output per
pound of wood. Improper operation and maintenance
may cause any wood burning unit to release more
particulate and adversely affect the environment.
It helps to know a little about the actual process of
burning in order to understand how to operate the
stove for best performance. The first stage of burn-
ing we will call the kindling stage. In this stage, the
wood is heated to a temperature high enough to
evaporate the moisture which is present in all wood.
The wood will reach the boiling point of water (212°F)
and will not get any hotter until the water is evapo-
rated. This process takes heat from the coals and
tends to cool the stove. Fire requires three things to
burn: fuel, air and heat. So, if heat is robbed from the
stove during the drying stage, the new load of wood
has reduced the chances for a good clean burn. For
this reason, it is always best to burn dry, seasoned
firewood. When the wood isnt dry, you must open
the air controls and burn the stove at a high burn set-
ting for a longer time to start it burning. The control on
the right side of the stove is called the primary con-
trol; it is used mainly during the kindling stage of burn-
ing, or when burning the stove at a high burn setting.
It should be closed (pulled outward) for lower burns.
The next stage of burning, the secondary stage, is
the period when the wood gives off flammable gases
which burn above the fuel with bright flames. During
this stage of burning it is very important that the flames
be maintained and not allowed to go out. This will in-
sure the cleanest possible fire. If you are adjusting
your stove for a low burn rate, you should close down
the air to the point where you can still maintain some
flame. If the flames tend to go out, the stove is set too
low for your burning conditions. The air control in the
center of the stove, beneath the ash catcher, is the
one used to adjust the stove for lower burn rates. This
is called the secondary control. Pulling either control
towards you closes it, pushing it in opens it.
The final stage of burning is the charcoal stage. This
occurs when the flammable gases have been mostly
burned and only charcoal remains. This is a naturally
clean portion of the burn. The coals burn with hot blue
flames. It is very important to reload your stove while
enough lively hot coals remain in order to provide the
amount of heat needed to dry and rekindle the next
load of wood. It is best to open the air controls for a
short while before reloading. This livens up the coal
bed. Open door slowly so that ash or smoke does not
exit stove through opening. You should also break up
any large chunks and distribute the coals so that the
new wood is laid on hot coals.
Following these standards for operation and mainte-
nance is a responsible action for the choice to heat
your home with wood. In addition, you will also ex-
tend the life of your wood stove for many years of use
and enjoyment.

SECONDARY AIR SYSTEM
The secondary air enters at the upper
front of the firebox, near the top of the
glass door. This preheated air supplies
the necessary fresh oxygen to mix with
the unburned gases, helping to create
secondary, tertiary and quaternary
combustions. This air is regulated by
the secondary control. For more sec-
ondary air push control in, for less sec-
ondary air pull control out.
PRIMARY AIR SYSTEM
The primary combustion air
enters at the rear of the fire-
box through the primary air
tubes. For more heat push
control in, for less heat pull
control out.

WOOD SELECTION AND STORAGE
Burn only dry seasoned wood! Dry and well-sea-
soned wood will not only minimize the chance of creo-
sote formation, but will give you the most efficient heat
output. Even dry wood contains at least 15% mois-
ture by weight and should be burned hot enough to
keep the chimney hot for as long as it takes to main-
tain particulate (smoke) burning. It is a waste of en-
ergy to burn unseasoned wood of any variety.
Dead wood lying on the forest floor should be consid-
ered wet, and requires full seasoning time. Standing
dead wood can be considered to be about two-thirds
seasoned. To tell if wood is dry enough to burn, check
the ends of the logs. If there are cracks radiating in all
directions from the center, it is dry. If your wood sizzles
in the fire, even though the surface is dry, it may not
be fully cured. Splitting wood before it is stored re-
duces drying time. Wood should be stacked so that
both ends of each piece are exposed to air, since more
BUILDING A FIRE
NOTE: Remove all labels from glass front prior to
lighting the first fire.
Before lighting your first fire in the stove, make cer-
tain that the baffle is correctly positioned. It should
be resting on the rear baffle support so that the hole
in the baffle lines up with the baffle locating pin (see
baffle installation instructions). You will be able to vi-
sually check this alignment.
There are many ways to build a fire. The basic prin-
ciple is to light easily-ignitable tinder or paper, which
ignites the fast burning kindling, which in turn ignites
the slow-burning firewood. Here is one method that
works well:
1. Place several wads of crushed paper on the fire-
box floor.
2. Lay small dry sticks of kindling on top of the paper.
3. Open primary and secondary controls fully.
4. Make sure that no matches or other combus-
tibles are in the immediate area of the stove. Be
sure the room is adequately ventilated and the
flue unobstructed.
5. Light the paper in the stove. NEVER light or re-
kindle stove with kerosene, gasoline, or charcoal
lighter fluid; the results can be fatal.
drying occurs through the cut ends than the sides.
This is true even with wood that has been split. Store
wood under cover, such as in a shed, or covered with
a tarp, plastic, tar paper, sheets of scrap plywood,
etc., as uncovered wood can absorb water from rain
or snow, delaying the seasoning process.
OVERFIRING
Do not overfire. Using flammable liquids or too much
wood, or burning trash in the stove may result in
overfiring. If the chimney connector or stove glows
red, or worse white, the stove is overfired. This con-
dition may ignite creosote in the chimney, possibly
causing a house fire. If any part of the insert starts to
glow, you are in an overfire situation. If you overfire,
immediately close the stove dampers and door, if
open, to reduce the air supply to the fire. OVERFIRING
YOUR STOVE VOIDS THE WARRANTY.
6. Once the kindling is burning quickly, add several
full-length logs 3 (76mm) or 4 (102mm) in di-
ameter. Be careful not to smother the fire. Stack
the pieces of wood carefully: near enough to keep
each other hot, but far enough away from each
other to allow adequate air flow between them.
7. When ready to reload the stove, add more logs.
Large logs burn slowly, holding a fire longer. Small
logs burn fast and hot, giving quick heat.
8. Adjust the primary and secondary air controls;
the more you close down the controls, the lower
and slower the fire will burn. The more open the
controls, the more heat will be produced.
As long as there are hot coals, repeating steps 7 and 8
will maintain a continuous fire throughout the season.
NOTE:The special high temperature paint that your
stove is finished with will cure as your stove heats.
You will notice an odor and perhaps see some vapor
rise from the stove surface; this is normal. We rec-
ommend that you open a window until the odor dissi-
pates and paint is cured.
NOTE: On a cold start-up, you may see a small
amount of smoke coming from the underside of stove
until chimney draft is established. This is normal, and
will stop when the loading door is closed.
