the air controls completely until the glowing has
stopped. OVERFIRING VOIDS WARRANTY.
4. Cool ashes should be disposed of carefully, using
a metal container.
5. Do not burn wet or green wood. Store wood in dry
location.
6. Do not burn garbage, treated wood, or wood with
salt (driftwood, etc.). Burning materials other than
wood (including charcoal) under adverse conditions
may generate carbon monoxide in the home, re-
sulting in illness or possible death.
7. Do not permit creosote or soot to accumulate ex-
cessively in the chimney or inside the firebox.
8. Check your chimney system thoroughly when install-
ing into an existing metal or masonry chimney. Seek
professional advice if in doubt about its condition.

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

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).
