What to Do if You Have a Chimney Fire
If you realize a chimney fire is occurring, follow these steps:
• Get everyone out of the house, including yourself.
• Call the fire department. If you can do so without risk to yourself, these additional steps
may help save your home. Remember, however, that homes are replaceable, lives are
not.
• Close the air controls on the insert.
• Use a garden hose to spray down the roof (not the chimney) so the fire won’t spread
to the rest of the structure.
• Once it’s over, call a CSIA Certified Chimney Sweep to inspect for damage. Chimney
fire damage and repair is normally covered by homeowner insurance policies.
2. Installation
WARNING
IF YOUR HWAM WOOD-BURNING INSERT IS NOT PROPERLY INSTALLED, OPERATED
AND MAINTAINED, A HOUSE FIRE MAY RESULT. FOR YOUR SAFETY, FOLLOW ALL
INSTALLATION, OPERATION AND MAINTENANCE DIRECTIONS.
Pre-Installation Check List
Before you begin an installation, review your plans and check to see that:
• Your insert will be far enough from combustible material to meet all clearance
requirements.
• Thefloorprotectionislargeenoughandisconstructedproperlytomeetallrequirements.
• You have all necessary permits from your local authorities. Your local building official
is the final authority for approving your installation as safe and in determining that it
meets all local and state building and safety codes.
The metal label permanently attached to the back of every HWAM wood-burning insert shows
that it has been tested to current UL and ULC safety standards, and gives the name of
the testing laboratory. Clearance and installation information is also printed on the label.
Local authorities will generally accept the label as evidence that, when the insert is installed
according to the information on the label and in this manual, the installation meets codes and
can be approved.
This wood insert must be installed in a code-approved masonry chimney with a flue liner
or a UL 127/ULC S610 approved factory fireplace. The insert must fit inside the existing
fireplace opening with a gap of at least 3/16” (5 mm) on each side and the top. The
approved masonry or factory fireplace the combustion chamber and chimney of the fireplace
must not be modified by removing bricks, mortar or any metal parts that would affect the
thermal characteristics or safety of the fireplace in any way. If the existing fireplace has
been modified in any way attach the metal tag stating “This fireplace has been altered to
accommodate a fireplace insert and must be re-inspected by a qualified person prior to re-
use as a fireplace “ to the back of the existing fireplace with nails or screws where it will be
seen by anyone removing the insert. In Canada this fireplace insert must be installed with
a continuous chimney liner of 6.0” (153 mm) diameter extending from the fireplace insert to
the top of the chimney. The chimney liner must conform to the Class 3 requirements of CAN/
ULC-S636, Standard for Lining Systems for Existing Masonry or Factory-Built Chimneys
and Vents, or CAN/ULC-S640, Standard for Lining Systems for New Masonry Chimneys.

6
For any unresolved questions about installation in the USA, refer to the national Fire
Protection Association’s publication ANSI/NFPA 211 Standard for Chimneys, Fireplaces,
Vents and Solid Fuel Burning Appliances. For installation in Canada, refer to CSACAN-B365,
Installation Code for Solid Fuel Burning Applications and Equipment. These standards are
the basis for many national codes. They are nationally recognized and are accepted by most
local authorities. Your local dealer or your local building official may have a copy of these
regulations.
WARNING!
CHECK ALL LOCAL BUILDING AND SAFETY CODES BEFORE INSTALLATION. THE
INSTALLATION INSTRUCTIONS AND APPROPRIATE CODE REQUIREMENTS MUST
BE FOLLOWED EXACTLY AND WITHOUT COMPROMISE. ALTERATIONS TO THE
INSERTARE NOTALLOWED. DO NOT CONNECT THE INSERT TOACHIMNEY SYSTEM
SERVINGANOTHER INSERT, APPLIANCE OR ANYAIR DISTRIBUTION DUCT. FAILURE
TO FOLLOW THESE INSTRUCTIONS WILLVOID THE MANUFACTURER’S WARRANTY.
NOTE
Before installing the insert into an existing masonry chimney or approved factory fireplace,
have the fireplace and chimney inspected by a local fire marshal or qualified installer.
Remember that the chimney and its location on the roof will affect the performance of the
insert. An oversized flue may not provide effective draft, and a flue liner may be required.
(Observe draft requirements.) Consult your dealer or qualified installer before final selection
is made.
Room Requirements
There must be a constant supply of fresh air to the room in which the insert is to be installed.
A window that opens or an adjustable air vent should suffice. Please be aware that not all
glass parts are heat-resistant. For this reason, a glass wall should sometimes be treated as a
flammable wall. Contact your local chimney sweep or glass producer to hear at what distance
the insert should be kept from glass.

Hearth and Floor Protection
The hearth and/or floor protection required depends on the height of the insert from the floor.
If this height, “H”, on the accompanying diagram is 14 inches (356 mm) or less there must
be a thermally rated non-combustible hearth/floor protector meeting or exceeding a thermal
rating of k=.42 or equivalent with a listed thickness of 1” (26 mm) minimum. The covering
must extend 12” (305 mm) in front of the insert and 8” (204 mm) to each side (measured from
the edge of the glass door).
If H is greater than 14 inches then only ember protection is required and must extend 18”
(mm) from the front of the insert and 8” (200mm) to each side (measured from the edge of
the glass door).
Using Alternate Material As Floor / Hearth Protection
Thehearthextensionoralternatematerialusedasafloor/hearthprotectormustbeconstructed
of a durable noncombustible material having an equal or better thermal conductivity value
(lower k value) of k =.42
BTU/IN FT2 HR °F or a thermal resistance that equals or exceeds r = 2.38 With these values,
determine the minimum thickness of the alternate material required using the formula(s) and
shown in Table ?.
Note:Any noncombustible material having a minimum thickness of 1”(26 mm) whose k value
is less than .42 or whose r value is more than 2.38 is acceptable. If the alternate material used
has a higher k value or lower r value will require a greater thickness of the material used. In
some cases, if the k value is less or the r value higher, a thinner material may be used.

Methods of determining floor protection equivalents:
To determine the thickness required for the alternate material when either the “k” value or “r”
value is known, use either the k formula or r formula.
Example: If Micore 300 Mineral Fiber Board is to be used for the floor protection, how thick
must this material be?
kM= k value per inch of alternate material
rM= r value per inch of alternate material
TM= minimum thickness required for alternate material
TS= standard thickness of the alternate material
kL = k value per inch of listed material
rL= r value per inch of listed material

Chimney Requirements
The chimney must be of a sufficient height to enable an adequate draft and to prevent smoke
problems. The minimum draft should be: approx. .048 inches of water or 12 Pa.
The chimney must have a minimum opening equivalent to 6.0” or 150 mm.
The chimney opening should always be at least the size of the outlet of the insert.
The chimney should have an easily accessible soot door.
Chimney Height Requirements
The chimney must extend 3 feet above the level of roof penetration and a minimum of 2
feet higher than any roof surface within 10 feet. Check with your local building officials for
additional requirements for your area.
The condition of the chimney and height is very important; we suggest a total minimum height
of 15’ (4.5 m), measured from the floor level on which the insert is installed.
Chimney
The chimney is essential to the functioning of the wood-burning insert. The chimney draft
provides a partial vacuum in the insert. This vacuum removes the smoke from the insert;
provides air for the glass air wash, which keeps the glass free of soot; and brings in air for
primary and secondary combustion.
Thechimneydraft iscreatedby thedifferencesintemperatureinside andoutsidethe chimney.
The higher the temperature within the chimney, the better the draft. It is crucial, therefore,
that the chimney is warmed through properly before closing the air control and limiting the
combustion in the insert (a brick chimney takes longer to warm through than a steel chimney).
On days where the weather and wind conditions create insufficient draft inside the chimney, it
is even more important to warm up the chimney as quickly as possible. The trick is to quickly
get some flames going. Split the wood into extra fine pieces, use an extra firelighter, etc.
If the insert has not been used for a long period, it is important to check that the chimney pipe
is not blocked.
Chimney Sweeping
To reduce the risk of chimney fires, the chimney must be cleaned every year. The flue duct
and the smoke chamber above the baffle plate inside the insert must be cleaned together
with the chimney. If the chimney’s height makes cleaning from above impossible, a cleaning
hatch must be installed in the chimney.

11
Components
Check the Assembly
Before you start using the insert, you must
ensure that all parts are fitted correctly.
• a. Secondary air baffle plate (1)
must lie on the rear plate and on the
slanting side plates. It must fall into
position in the track on the rear plate.
• b. Steel smoke deflector plate (2)
is mounted on two hooks. To mount
the plate, lift it up and lead to the right
until it is hanging on the two hooks.
3D view of the Skamol refractory plates.
Skamol is a very heat-resistant and highly-
insulating material made of processed
vermiculite. This material is capable of
service temperatures up to 1150 C (2101 F).
It is however somewhat fragile. Care should
be used when handling these pieces and
when fueling the insert.

12
Automatic Control
Brilliantsolutionsareoftensimplelittledetails
which nevertheless make a huge difference
in our everyday lives. HWAM’s patented
automatic system consists of a small spring
which automatically regulates the supply
of air to the combustion chamber. Simple,
convenient operation - The automatic system
optimizes the combustion for you. All you
need to do is to light up the insert and enjoy
the flames and the heat to the fullest. When
you add more firewood, the system will
automatically readjust the insert to achieve
the optimum combustion.
HWAM AutomaticTM
The control arm starting point on a cold insert should be 75° above horizontal. It should feel
easy going and bouncy when you push it. The damper plates must be dry and clean and slide
together easily. Control bars and slide gates may be lubricated with WD40 (never oil).
Skamol
SkamolrefractoryplatesaredeliveredinallHWAMwood-burninginserts.Werecommendthat
you treat the Skamol refractory plates with care because it is a delicate material (not covered
by the limited warranty). Small cracks may arise in the Skamol from minor water content,
especially if the insert is overheated during the first fire. These cracks do not influence the
performance of the insert and are not covered by the limited warranty.
Glass
The glass is a heat-resistant ceramic glass that can withstand continuous temperatures up to
1390°F (754°C). This temperature is well above the temperatures at which you will operate
your insert. This insert is designed to provide a flow of air over the inside of the glass.This air
combined with high temperatures helps keep the glass optimally clean. When operating the
insert on low for extended periods of time, the glass may become dirty. A short, hot fire will
help clean off much of the normal soot buildup (see section 5: Troubleshooting). In order to
keep glass soot free, the moisture content of the wood must be between 15 and 18%.
Smoke Detectors
HWAM strongly recommends installing smoke detectors throughout your home. However, do
not install them too close to the insert as the heat can activate them.
Protected Wall Reduced Clearances
Local codes in some areas will allow reduced clearances when the insert is installed adjacent
to a protected wall system. Your local building official must approve the variance. Check your
local building codes or with a qualified installer.

13
Room Ventilation and Combustion Air Supply
Provide for an adequate supply of air for combustion. Proper ventilation is essential when
using a solid fuel-burning appliance. The combustion process uses oxygen from inside the
dwelling, and if there is not adequate make-up air (such as in newer homes which are well
insulated and weather tight), it may be difficult to obtain an adequate draft in your chimney
(caused by a shortage of air in the house). To correct this, it may be necessary to crack a
window on the windward side of the dwelling, or provide combustion air to a nearby floor/wall
vent (fresh air duct), or directly to the insert. Please refer to your local building codes.

Mounting and Connection (Drawing A1-A3)
The HWAM I 30/55 consists of a moveable, external steel case, as well as an inner cassette
that is pushed into place and connected once the external steel case is installed.
1. Mounting and Connecting in an Existing Fireplace (Drawings A1-A3).
• Before mounting the insert in a masonry fireplace, the damper in the existing chimney
mustberemoved,andthesmokeneck,ifany,shouldbewidenedsothattheconnecting
pipe from the insert can be connected directly to the stainless steel chimney liner
(supplied by others).
• In advance, decide with a specialist or the chimney sweep where a soot door (1)
should be placed, so that the chimney can be cleaned from above while the door of
the insert remains closed.
Note: The outer case is not load-bearing. Therefore, stainless steel liners exceeding 6’ or 2 m
in length must be secured (using hangers) to avoid putting any load on the outer case.
2. Attach Connector Tube to Stainless Steel Flue Liner.
• The inside diameter of the flue liner and connector pipe must not be smaller than
6”(153 mm) diameter single wall 24 gauge MSG (0.58 - 0.71 mm) attach the flue liner
to the connector tube or between all sections using 3 sheet metal screws. Insert inner
tube into the flanged end of the connector tube. Orient the inner tube so the handle is
closer to the inside of the connector tube.
Mounting the Connecting Pipe (Drawing A1)
• Trim approximately 3 fireproof batts (supplied by others) 2.0” or 50 mm thick each
(4) so that they fit tightly into the chimney space and cut a hole in the center to fit
tightly around the tube.
• Locate the assembled connecting pipe and liner in the fireplace so that the front of the
insert is in the correct position. Consult the dimensions in drawing A1.

17
Distance a. 15 3/8”(39.1 cm) - Distance from front edge of the brick hole, if the insert must
be flush with the brickwork.
Distance b. 15 7/8” (40.4 cm) - Height from the bottom of the insert to bottom of
connector tube.
• Now push the three batts up around the stainless steel flue liner and press them up
into the chimney, thereby achieving a compact and tight-fitting seal.
3. Installing the Outer Case (Drawing A2)
• Remove inner cassette from outer case.
• Push the outer case (6) into place at the bottom of the fireplace.
• Shim outer case level to the ash lip of the existing fireplace if necessary.
• Level the outer case. Carefully ensure that the outer casing is level and that its front
edge is flush with the brickwork. The three adjustment screws in the bottom of the
casing can be used for fine adjustment so that the casing is completely level.
• Screw the connector pipe to the to the outer case from the inside with the help of the
self-tapping screws supplied.
• If the gap between the fireplace opening and the outer case is to be closed with
brickwork, there must be a minimum distance of 5 mm (3/16”) around the outer case.
Any brickwork above the outer casing must therefore be self-supporting. Attach outer
case to the existing fireplace with 3 screws (supplied by others) through the bottom of
the outside case.

18
4. Install Inner Cassette (Drawing A3)
• Checkthepositionand operation ofthecontrol arm ontheautomaticair controlsystem.
• Remove the secondary air baffle (7) from the inner cassette.
• Remove the smoke deflector plate (8). place 6 mm gasket in groove of the flue outlet.
• Slide the inner cassette inside the outer case. Check the alignment with the connector
tube. Pull the handle of the inner tube down into the smoke outlet bushing so that the
inner tube makes full contact with the gasket.
• Replace the secondary air baffle (7) and the smoke deflector plate (8).
5. Seal the Liner and Chimney
• Seal between the stainless steel liner and chimney on top of the batts using heat-proof
mortar (5). This can be done through the soot door (1) of the chimney, and should
only be done after the insert is assembled. If there is no soot door you must extend
the chimney liner to the top of the chimney where it should be sealed with heat-proof
mortar.
Optional - Connecting External Supply of Fresh Air
The HWAM I 30/55 can be connected to fresh air systems. The fresh air system can be
purchased separately.
6. Install the Door Glass
• Begin by installing the handle to the bottom of the door
with the screws (6 mm x 12 mm) provided.
• Check that the rubber gaskets are in the proper place
in the glass support bracket.
• Slide the glass down into the glass support brackets
that are part of the handle. Be sure the painted side
of the glass is towards the insert. It may help to tip the
glass slightly away from the top of the insert as you
slide it in. Make sure the glass is centered on the door
handle.
• Next, slide the top support brackets over the top edge of the glass and fasten to the
door with the screws provided.
3. Operating the HWAM 3055 Insert
The insert is hot while in operation. Do not touch. Keep children, clothing and furniture
away. Contact may cause skin burns. Use gloves when stoking the fire.
WARNING! DO NOT USE GASOLINE, LIGHTER FLUID, KEROSENE OR OTHER
FLAMMABLE LIQUIDS TO START OR FRESHEN A FIRE IN THE INSERT. KEEP ALL
SUCH LIQUIDS WELL AWAY FROM THE INSERT WHILE IT IS IN USE.
Fueling the Wood-burning Insert
Your HWAM freestanding wood-burning insert is designed for burning dry natural well-
seasoned wood only. Wood should be stored in a dry place for at least two years before being
used for fuel. Some trees have very high moisture content and it is necessary to thoroughly
dry the wood. Cutting and splitting the wood, then stacking it with both ends of the stick
exposed, can speed up the drying process. More drying occurs through the end than through
the sides even when the wood is split. We recommend that the moisture content of the wood

19
be between 15-18%. If your wood sizzles, or you see bubbles coming from the end of the
logs, the wood is not dry.
Green or uncured wood does not work well as fuel, and can cause increased creosote
buildup. The value of green wood as a source of heat is limited. Do not overload, use kindling
wood, or mill ends for primary fuel as this may cause over-firing. Although feeding excessive
amounts of fuel to the insert should be avoided, it is important to supply it with sufficient fuel
to maintain a moderately hot fire (this is particularly important since burning wood produces
volatile substances).
Do not store wood within the installation clearances or within the space required for refueling
or ash removal.
WARNING! BURNING MATERIALS OTHER THAN NATURAL DRY WELL-SEASONED
WOOD MAY SHORTEN THE LIFE OF YOUR INSERT AND POSSIBLY LEAD TO A
DANGEROUS OVER-FIRING CONDITION. DO NOT BURN GARBAGE, PARTICLE
BOARD, SCRAPS OR PRESSED LOGS USING BONDING AGENTS BECAUSE THEY
CAN PRODUCE CONDITIONS, WHICH WILL DETERIORATE METAL. OVER FIRING THE
INSERT MAY CAUSE PAINT DISCOLORATION. A WHITE GLAZE ON THE GLASS IS AN
INDICATION OF OVER FIRING.
When you light up for the first time, the insert must be heated gradually. This is very important.
Failure to do this may cause cracks to appear in the Skamol or problems with the paint. Do
not build the fire too close to the glass. Keep the wood at least 2” (51 mm) away from the
glass. Build a very small fire with small sticks weighing a total of 1 to 1.5 lbs. Let the fire
go completely out. Then build a slightly larger fire with up to 2.5 lbs of wood and let the fire
go out again. You may then proceed to fire the insert at a rate not to exceed 5 lbs per hour.
The coating on the insert will cure the first time the insert is fired. Open the door carefully;
otherwise there is a risk that the gaskets will stick to the paint. Ensure adequate ventilation
while the odor is present.
WARNING IF YOU TOUCH BURNING WOOD OR ASHES WITH YOUR GLOVE BE
SURE TO PLACE THE GLOVE ON A NON-COMBUSTIBLE SURFACE AFTER USE.
LIVE EMBERS CAN STICK TO THE GLOVE AND CAUSE COMBUSTIBLE SURFACES
TO CATCH FIRE RESULTING IN INJURY, PROPERTY DAMAGE OR LOSS OF LIFE.
Approved Fuel Types
The insert is approved for combustion of wood only. It is recommended to use dry wood
with a water content of a maximum of 20%. Stoking a fire with wet wood results in soot,
environmental problems, and less efficient fuel economy.
Recommended Wood Types
All types of wood, for instance, birch, beech, oak, elm, ash, conifers, and fruit trees can be
used as fuel in your insert. The great difference is not in the fuel value, but in the weight of
the wood types per cubic meter. Since beech weighs more per cubic meter than, for instance,
common spruce, it will take more common spruce to produce the same amount of heat that
you would get from a cubic meter of beech.
Banned Fuel Types
Do not stoke a fire with the following:
• Printed matter

20
• Plywood, plastic
• Rubber
• Fluid fuels
• Rubbish such as milk cartons, lacquered wood or impregnated wood
• Coal, briquettes and coke
The reason that you should not apply any of the above is that during combustion they develop
substances that are health hazardous and harmful to the environment. These substances
can also damage your insert and chimney, rendering the product warranty void.
Opening and Closing The Up-Swing Door on Model 04111
Always hold the handle in the middle when opening and closing the door to avoid putting
uneven pressure on the door lift mechanism.
Please note that it is important not to let go of the handle when opening and closing the door.
The glass could be damaged if the door is allowed to open or close on its own.
Controlling the Combustion
Primary air control (1) is located behind the glass. The automatic air control function is set to
maximum when the adjustment bar is set to the right-most position, and minimum when the
bar is set to the left-most position.
Starting the Insert
• Do not elevate the fire on a grate. Build fire directly on the hearth inside the insert.
• Push the primary air control all the way to the right to set the automatic control to maximum
effect.
• Put split kindling, corresponding to two to three pieces of wood (about 4 lbs/2 kg),
into the insert.
• Put two fire lighters in between the kindling. Light them and allow the flames to spread
slowly. Keep the door ajar until no more condensation forms on the glass (for a
maximum of 5 min.). Close the door.
