C. Fuel
1. Hardwood vs. Softwood
Your replace’s performance depends on the quality of
the rewood you use. One species of wood varies very
little to the other in terms of energy content. All sea-
soned wood contains about 8,000 BTU’s per pound.
Hardwoods have a greater density than softwoods; a
piece of hardwood will contain about 60% more BTU’s
than an equal size piece of softwood. A cord of sea-
soned oak (hardwood) would contain about 60% more
potential energy than a cord of seasoned pine (soft-
wood).
Most softwoods are coniferous. These are trees with
needle-like leaves that stay green all year and carry
their seeds exposed in a cone. Examples of conifer-
ous trees are Douglas r, pine, spruce and cedar. Soft-
woods, being more porous, require less time to dry,
burn faster and are easier to ignite than hardwoods.
Hardwoods are deciduous trees, broadleaf trees that
lose their leaves in the fall. Their seeds are usually
found within a protective pod or enclosure. Some ex-
amples of deciduous trees are oak, maple, apple, and
birch. However, it should be noted that there are some
deciduous trees that are denitely not considered hard-
woods such as poplar, aspen and alder. Hardwoods
require more time to season, burn slower and are usu-
ally harder to ignite than softwoods. Obviously, you will
use the type of wood that is most readily available in
your area. However, if at all possible the best arrange-
ment is to have a mix of softwood and hardwood. This
way you can use the softwood for starting the re, giv-
ing off quick heat to bring the replace up to operating
temperature. Add the hardwood for slow, even heat and
longer burn time.
WARNING! For use with solid wood fuel only.
Otherfuelsmayoverreandgeneratepoisonousgases(i.e.
carbon monoxide).

WARNING! Risk of Fire!
• DO NOTburnwetorgreenwood.
• Wet, unseasoned wood can cause accumulation of
creosote.
2. Moisture content
The majority of the problems replace owners expe-
rience are caused by trying to burn wet, unseasoned
wood. Freshly cut wood can be as much water as it is
wood, having a moisture content of around 50%. Imag-
ine a wooden bucket that weighs about 8 pounds. Fill it
with a gallon of water, put it in the rebox and try to burn
it. This sounds ridiculous but that is exactly what you
are doing if you burn unseasoned wood. Dead wood
lying on the forest oor should be considered wet, and
requires full seasoning time. Standing dead wood can
be considered to be about two-thirds seasoned, if cut at
the dry time of the year.
Burning wet, unseasoned wood will produce less heat
output because it requires energy in the form of heat
to evaporate the water trapped inside. This is wasted
energy that should be used for heating your home. This
moisture evaporates in the form of steam which has
a cooling effect in your rebox and chimney system.
When combined with tar and other organic vapors from
burning wood it will form creosote which condenses in
the relatively cool rebox and chimney.
Even dry wood contains at least 15% moisture by
weight, and should be burned hot enough to keep the
chimney hot for as long as it takes to dry the wood out
- about one hour. 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 re, even though the surface is dry, it may
not be fully cured.
3. Seasoning
Seasoned rewood is nothing more than wood that is
cut to size, split and air dried to a moisture content of
around 20%. The time it takes to season wood varies
from around nine months for soft woods to as long as
eighteen months for hardwoods. The key to seasoning
wood is to be sure it has been split, exposing the wet
interior and increasing the surface area of each piece.
A tree that was cut down a year ago and not split is
likely to have almost as high a moisture content now as
it did when it was cut.
To season wood:
• Cut logs to size
• Split to 6 in. (152 mm) or less
• Air dry to a moisture content of around 20%
- Soft wood - about nine months
- Hard wood - about eighteen months
NOTICE: Seasoningtimemayvarydependingondrying
conditions.
4. Storing Wood
Splitting wood before it is stored reduces drying time.
The following guideline will ensure properly seasoned
wood:
• Stack the wood to allow air to circulate freely around
and through the woodpile.
• Elevate the woodpile off the ground to allow air
circulation underneath.
• The smaller the pieces, the faster the drying process.
Any piece over 6 in. (152 mm) in diameter should be
split.
• Wood should be stacked so that both ends of each
piece are exposed to air, since more 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. Avoid
covering the sides and ends completely. Doing so
may trap moisture from the ground and impede air
circulation.

WARNING! Risk of Fire! Keep combustible materials,
gasolineandotherammablevaporsandliquidsclearof
thereplace.
DO NOT:
• storeammablematerialsclosetothereplace
• use gasoline, lantern fuel, kerosene, charcoal lighter
uidorsimilarliquidstostartor“freshenup”areinthis
replace.
E. Lighting Instructions
NOTICE: Youmustestablishagooddrafttopreventsmoke
spillageintotheroom.
The rst three or four res should be of moderate size to
allow the oils and binders to be burned from the replace
and the refractory and paint to cure. You may notice an in-
dustrial odor the rst few res. This is considered normal.
Use well-seasoned wood.
• Open the ue damper to a fully open position.
• Place crumpled or twisted paper under the replace
grate.
• Loosely arrange kindling or small pieces of wood to form
a ‘tent’ on the replace grate.
• Pre-warm the ue to establish a draft to help reduce
smoke spillage during start-up. Hold a rolled up piece
of burning newspaper under the ue damper for a few
moments.
• Light the crumpled paper to ignite the kindling.
• Add small pieces of wood until a hot bed of embers has
been established.
• Add a minimum of three average size pieces of split
rewood, placed to allow combustion air and ames
between them.
5. Burning Process
Fire requires fuel, air and heat. If heat is robbed from
the replace during the drying stage, the new load of
wood has reduced the chances for a good clean burn.
Always burn dry, seasoned rewood.
6. Creosote Formation
When wood is burned slowly, it produces tar and other
organic vapors which combine with expelled moisture
to form creosote. The creosote vapors condense in
the relatively cool chimney ue of a newly-started or
a slow-burning re. As a result, creosote residue ac-
cumulates on the ue lining.
When ignited, creosote creates an extremely hot re
which may damage the chimney or even destroy the
house.
The chimney shall be inspected at least annually be-
fore lighting, or once every two months during heating
season.
When creosote has accumulated it shall be removed to
reduce the risk of a chimney re.
7. Processed Solid Fuel Firelogs
Manufactured relogs may be used with this replace.
Vermont Group recommends the use of UL Classied
processed fuel relogs. Follow the manufacturer’s light-
ing and safety instructions.
Using relogs may require more frequent chimney in-
spections and cleaning.
Do not poke or stir the logs while they are burning. Use
only relogs that have been evaluated for the appli-
cation in manufactured replaces and refer to relog
warnings and caution markings on packaging prior to
use.
D. First Fire
Before lighting your rst re in the replace, make certain
that:
• refractory is in place
• all labels have been removed

5 Troubleshooting
Start Fire Problems Possible Cause Solution
Can’t get re started
Excessive smoke or spillage
Burns too slowly
Smolders, sizzles
Not enough kindling/paper or no
kindling/paper
Use dry kindling, more paper. Arrange kindling & wood for
air movement.
Damper closed/not fully open Open damper.
Not enough air for re to ignite Check for restricted cap/shroud.
Open air kit (if installed).
Check for ue blockage.
Pre-warm ue before starting re (refer to starting re
section).
Check for adequate vent height (refer to chimney
assembly section).
Open window below the replace towards the wind.
Wood condition is too wet, too large Use dry, seasoned wood (refer to wood fuel section).
Bed of coals not established before
adding wood
Start with paper & kindling to establish bed of coals (refer
to starting re section).
Flue blockage such as birds’ nests
or leaves in termination cap
Have chimney inspected for creosote and cleaned by a
certied chimney sweep.
Down draft or negative pressure
Competition with exhaust devices
Do not use exhaust fans during start-up (refer to negative
pressure section).
Open window below the replace towards the wind.
Fire burns too fast Extremely dry or soft wood Mix in hardwood.
Mix in less seasoned wood after re is established (refer
to wood fuel section).
No glass doors Add glass doors to slow down air ow.
Overdrafting Check for correct vent height; too much vertical height
creates overdrafting.
Check location of vent termination (refer to chimney
assembly section).

A. FAQs
If smoke spillage occurs from a replace opening when
the door is open, there is either a leakage in the ue, a
blockage in the ue, or some condition is affecting draft
Understanding and differentiating the conditions which
can cause each of these kinds of spillage problems is
essential to their solution.
• Flue Leakage
Check for improperly connected flue joints or a
damaged ue joint in the chimney system. Such
leakage would reduce draft (air would be drawn in
through the leaks rather than through the replace).
The result might be difficult start-up and smoky
res that might spill if other adverse draft conditions
accompany this problem.
• Flue Blockage
The damper should be open.
Check for objects that may have fallen down the
chimney.
Be sure you have air available for combustion and that
your rewood is dry and well seasoned. Build your res
properly and according to the instructions given in op-
erating instructions, “Starting a Fire”. Be sure your ue
system is installed correctly and that it is the proper di-
ameter and height. Check for the following:
• All chimney sections are properly installed.
• The chimney is clean and free of creosote or soot
buildup.
• Make sure overhanging trees and branches are cut
back within ten feet of the top of the chimney and the
chimney is free of debris from animals.
• Ensure the chimney cap is clean and free of any
buildup of soot or creosote if cap is equipped with a
spark arrestor screen.
• The wood being used in dry and well seasoned.
If you still suspect you have a low draft problem it may
be necessary to increase the volume of air in your
ue system. Since the diameter of your ue system is
matched with the size of the ue collar and should not
be changed, then the height of the system must be in-
creased. Add chimney sections one at a time until the
draft improves.
In some cases, regardless of what you do, it can still be
difcult to establish the proper ue draft. This is espe-
cially evident when using an exterior factory-built chim-
ney or exterior masonry chimney. Try holding a burning
rolled up newspaper as close to the ue outlet as pos-
sible for a few minutes, then light the paper under the
kindling. The heat generated from the burning rolled up
newspaper should help get the draft established.
Still other factors can affect how well your ue system
performs. Neighboring structures, high winds, tall trees,
even hillsides can affect air currents around the chim-
ney. Well designed chimney caps are available that can
help. Your replace dealer is the local expert in your
area. He can usually make suggestions or discover
problems that can be easily corrected allowing your
replace to operate correctly as it has been designed,
providing safe and economical heat for your home.
Flue draft is measured as negative pressure in the
chimney. The amount of negative pressure determines
how strong the draft is. The draft is important because
it draws the combustion air into the replace and pulls
the smoke out of the chimney.
There are three basic criteria essential in establishing
and maintaining ue draft:
• availability of combustion air
• heat generated from the re
• diameter and height of the ue system
These three factors work together as a system to create
the ue draft. Increasing or decreasing any one of them
will affect the other two and thus change the amount of
draft in the entire system.
If the re is hard to start and smoke spills out of the re-
place, or you nd it difcult to establish and maintain a
moderately high burn rate, then the ue draft is too low
and corrective measures must be taken.
Vermont Castings Group assumes no responsibility
for the improper performance of the replace system
caused by inadequate draft due to environmental con-
ditions, down drafts, tight sealing construction of the
structure, or mechanical exhausting devices which
will create a negative air pressure within the structure
where the replace is located.

tion regarding operation and troubleshoot-
ing. Visit www.vermontcastingsgroup.com
