Operating Instructions
FIRST START
When rst installed, the chimney, rebricks and steel are cold and it usually takes several hours on a fairly
high burn for them to become hot and dry enough for the stove to function well. We recommend during
the unit’s rst burn that a door and window are opened to vent the smoke and fumes created from the
unit’s paint curing. The paint will smell a little for the rst burn or two as it cures.
DISPOSAL OF ASHES:
If you let the ashes accumulate two or three inches on the oor they tend to burn themselves up.
Ashes should be placed in a metal container with a tight tting lid. The closed container of ashes should
be placed on a noncombustible oor or on the ground, well away from all combustible materials, pending
nal disposal. If the ashes are disposed of by burial in soil or otherwise locally disposed, they should be
retained in the closed container until all cinders have thoroughly cooled. Other waste shall not be placed
in this container.
FAN OPERATION:
All models have been approved for operation with the fans supplied by the manufacturer. On medium or
high burns, using a fan will increase the heat transfer slightly. Route the electrical cord along the oor in
front of the surround panel. There are cutouts in the castings to tuck the cord under.
1. Plug the fan assembly into a standard three (3) prong grounded electrical receptacle.
2. The fan is controlled by a rotary dial located at the lower left side of the unit. The dial rotation is as
follows: OFF>HIGH>LOW
3. If the dial is in any position in the high to low range, the fan will automatically turn on once the
stove has reached operating temperature (roughly 25 mins from a cold start). When the unit cools
down, the fan temperature sensor will shut the fan off automatically. The fan can also be turned off
manually at any time by rotating the dial to the off position.
REPLACING THE GLASS:
Never strike or slam the door, hit the glass or let burning wood rest against it. If the glass cracks when
the re is burning, do not open the door until the re is out and do not operate the stove again until
the glass has been replaced. If the glass is damaged in any way, a factory replacement is required (see
“
Parts List”). To replace the glass, remove the steel retaining clips and all loose glass. Replace only with
Neoceram 5 mm glass 16.61” (422 mm) x 10.63” (270 mm) and wrap the edges with 0.125” (3.2 mm) x
0.5” (13 mm) self-adhesive berglass gasket.
Wear gloves when handling damaged glass door assembly to prevent personal injury. When the glass
door assembly is being transported, it must be wrapped in newsprint and tape and/or a strong plastic bag.
The glass must be purchased from an ENVIRO dealer. No substitute materials are allowed.
FIRE EXTINGUISHER AND SMOKE DETECTION:
All homes with a solid fuel burning stove should have at least one re extinguisher in a central location
known to all in the household and a smoke detection device in the room containing the stove. If it sounds
the alarm, correct the cause but do not deactivate. You may choose to relocate the smoke detection
device within the room; DO NOT REMOVE THE SMOKE DETECTOR FROM THE ROOM.

Operating Instructions
CREOSOTE - ITS FORMATION AND NEED FOR REMOVAL:
When wood is burned slowly, it may produce tar and other organic vapors, which combine with expelled
moisture to form creosote. The creosote vapors condense in the relatively cool chimney of a slow-burning
re. As a result, creosote residue accumulates on the ue lining. When ignited this creosote makes an
extremely hot re. The chimney connector and chimney should be inspected bi-weekly during the heating
season to determine if a creosote buildup has occurred. If creosote has accumulated (3mm or more) it
should be removed to reduce the risk of a chimney re.
MAINTENANCE:
At the end of each heating season clean the chimney and the smoke pipe. If soot has accumulated above
the top bafe bricks, remove, clean, and then replace them. If a secondary air tube is badly corroded,
replace it. Replace worn door gaskets and broken bricks as needed.
FAILURE TO INSPECT AND CLEAN YOUR CHIMNEY SYSTEM REGULARLY CAN RESULT IN A
CHIMNEY FIRE, WHICH COULD DAMAGE THE CHIMNEY OR CAUSE A HOUSE FIRE.
CHIMNEY OR RUN AWAY FIRE:
1. Call local re department (or dial 911)
2. Close the draft fully
3. Examine the ue pipes, chimney, attic, and roof of the house, to see if any part has become hot
enough to catch re. If necessary, spray with re extinguisher or water from the garden hose.
4. Do not operate the stove again until you are certain the chimney and its lining have not been
damaged.
Building Your Fire:
Proper operation of your stove will help to ensure safe, efcient heating. Please take a few moments to
review these simple operating procedures.
IMPORTANT: Please be aware when loading your stove that the air tubes in the rear are lower.
1. Fuel Selection:
This stove is designed to burn natural wood only. Higher efciencies and lower emissions generally result
when burning air-dried seasoned hardwoods, as compared to softwoods or too green or freshly cut
hardwoods. DO NOT BURN the following: treated wood, coal, garbage, solvents, colored papers or trash.
Burning these may result in the release of toxic fumes and may poison or render the secondary air tubes
ineffective. Burning coal, cardboard or loose paper can produce soot, or large akes of char or y ash that
can coat the combustor, causing smoke spillage into the room, and rendering the combustor ineffective.
2. Building/Maintaining a Fire:
a) Open the primary air slide by pulling it all the way to the right.
b) Place a base of crumpled uncolored newspaper in the bottom of the stove. Lay pieces of kindling on
top of the newspaper and light it.
CAUTION: “Never use gasoline, gasoline-type lantern fuel, kerosene, charcoal lighter uid,
or similar liquids to start or “freshen up” a re in this heater. Keep all such liquids well
away from heater while it is in use.
c) As the kindling begins to burn, add several larger pieces of wood until the re is burning well. At this
point, regular size logs may be added.
5
Operating Instructions
NOTE: Until the re is burning well, leave the air controls fully open.
d) Regulate the heat output of the stove by adjusting the air controls to allow a larger re and vice versa.
A short period of experimentation with the control settings will allow you to regulate the heat output
to keep your home comfortable.
Do not use a grate or elevate the re. Build wood re on the stove rebox hearth oor.
3. Refueling the Stove:
Use a long pair of gloves (barbecue gloves) when feeding the re because these stoves burn at the front.
They are clean and efcient but they are also very hot and gloves are useful. Keep a small steel shovel
and whisk nearby for moving a log or lifting a fallen ember and for keeping the hearth clean.
a) Before attempting to add fuel to the stove, OPEN the damper control fully by pulling it all the way out.
This allows the chimney to carry away the additional smoke, which occurs when the door is open.
b) DO NOT OVERLOAD THE STOVE. Normally, three or four logs will provide heat for several hours.
Never operate this stove where portions glow red hot.
c) DO NOT OVERFIRE. If the heater or chimney connector glows, you are overring. Overring could
ignite creosote in the chimney and cause a house re.
d) CAUTION: DO NOT PLACE FUEL OR COMBUSTIBLE MATERIAL WITHIN SPACE HEATER INSTALLATION
CLEARANCES OR WITHIN THE SPACE REQUIRED FOR CHARGING AND ASH REMOVAL. LOGS SHOULD BE
KEPT IN A BIN OR CONTAINER TO REDUCE THE RISK OF LOGS ROLLING INTO THE UNIT’S CLEARANCES.
e) KEEP THE ASH LIP CLEAR OF EMBERS AND ASH. If the door is closed with debris in the way,
the door gasket seal could be compromised.
4. For Maximum Efciency:
When the stove is hot, load it fully to the top of the door opening and burn at medium low settings. When
the fuel is mostly consumed, leaving a bed of red coals, repeat the process. Maximum heat for minimum
fuel occurs when the stove top temperature is between 250°F (120°C) and 550°F (290°C). The most
likely causes of dirty glass are: not enough fuel to get the stove thoroughly hot, burning green or wet
wood, closing the draft until there is insufcient air for complete combustion, or a weak chimney draw.
Indeed, the cleanness of the glass is a good indicator of the stove operating efciently.
Helpful Hints Worth Repeating
1. Helpful advice on the correct way to start your re.
a) You will need small pieces of dry wood, called kindling, and paper. Use only newspaper or paper
that has not been coated or had other materials glued or applied to it. Never use coated (typically
advertising yers) or coloured paper.
b) Always open the door of the wood stove slowly to prevent suction and drawing smoke into the
room.
c) Crumple several pieces of paper and place them in the center of the rebox and directly onto the
rebricks of the wood stove. Never use a grate to elevate the re.
d) Place small pieces of dry wood (kindling) over the paper in a “teepee” manner. This allows for good
air circulation, which is critical for good combustion.
e) Light the crumpled paper in 2 or 3 locations. Note: It is important to heat the air in the stovepipe for
draft to start.
f) Fully open the air controls of the wood stove and close the door until it is slightly open, allowing for
much needed air to be introduced into the rebox. Never leave the door fully open, as sparks from
the kindling may y out of the stove, causing damage or injury. As the re begins to burn the kindling,
6
Operating Instructions
some additional kindling may be needed to sustain the re. DO NOT add more paper after the re has
started.
g) Once the kindling has started to burn, add some smaller pieces of seasoned, dry rewood. Note:
Adding large pieces at the early stages will only serve to smother the re. Continue adding small pieces
of seasoned dry rewood, keeping the door slightly open until each piece starts to ignite. Remember
to always open the door slowly between placing wood into the re.
h) Once the wood has started to ignite and the smoke has reduced, close the wood stove door fully. The
reduction of smoke is a good indication that the draft in the chimney has started and good combustion
is now possible. Larger pieces of seasoned, dry rewood can now be added when there is sufcient
space in the rebox. Adjust the air control setting to desired setting. Note: The lower the air control
setting, the longer the burn time of your rewood.
2. What type of wood is best to use as rewood?
Both hardwood and softwood burn well in this stove. Both woods contain about 8,000 BTU/lb (18,570
KJ/Kg), but hardwood is generally more dense, will weigh more per cord, and burns a little slower and
longer. Cutting rewood so that it will t horizontally, front to back, makes it easier loading and less likely
for the fuel to roll on the glass. Except for a cold start, there is no need to crisis-cross the logs. Ideal
length for the logs used in the 1200-C would be about 16“ (381 mm) but it can burn pieces up to 18”
long. Ideal length for the logs used in the 1700-C would be about 18“ (381 mm) but it can burn pieces
up to 20” long logs. Burn only dry, seasoned wood. It produces more heat and less soot or creosote.
Freshly cut wood has about 50% moisture. A 10 pound (4.5 Kg) log contains 5 pounds (2.3 Kg) of water.
To season rewood, split and stack it so that air can get to all parts of the wood. Burn beach wood only
if its salt content has been washed away in a season of rain and then the wood dried. To prevent smoke
spillage when refueling, open the door slowly.
3. What does dry, seasoned wood mean?
Wood that has been dried for a period of one year in a well-ventilated and sheltered area would be
considered dry, seasoned wood. Wood from slow-growing trees is generally considered better than wood
from fast-growing trees. To season rewood, split and stack it so that air can get to all parts of the
wood.
4. Will following the above-listed steps for starting a re mean perfect results every time?
The quick answer is ‘most of the time’. There are many variables that may affect your success when
starting a re. Most of those variables and how to deal with them will be learned through experience.
Your ability to start a good re will signicantly increase with time and patience. Some of the reasons for
poor stove performance will be covered in the next section of these instructions.
5. Why can’t I get the re lit?
Damp or wet wood and poor drafts are the main reasons for poor results in starting a re. Always use
dry, seasoned wood for your re. Even wood dried for two years will be difcult to ignite if it has become
wet.
6. Is it normal for soot to cover the glass at the beginning of a re?
Your stove has been built with an air-wash system that will help keep the glass clear when the rebox
has reached a good operating temperature and has a good draft. Normally, a hot stove will keep the glass
7
Operating Instructions
clean, but if you must clean the glass, use a soft cloth with no abrasive and clean only when the unit is
cold. Cold rebox temperature and poor draft cause sooting of the glass. Once the rebox temperature
and the draft increase, the soot will burn off.
7. What is draft?
Draft is the ability of the chimney to exhaust or draw smoke produced during the normal combustion
process. Too much draft may cause excessive temperatures in the appliance and may damage the
appliance. Inadequate draft may cause backpufng or “plugging” of the chimney. There is a certain
amount of draft that is required to allow for your stove to function at its’ highest efciency. A water
column gauge can be used to reference this amount.
8. What can cause a poor draft?
The most common factors for poor draft are:
a) Air supply
b) Environmental conditions
c) Cold chimney temperature
d) Poor chimney installation and maintenance
e) Atmospheric pressure
a) Air supply – Inside the home, normal household appliances such as clothes dryers and forced-air
furnaces compete for air, resulting in air starvation to the re. This creates a condition in the house
known as negative pressure. When a house experiences negative pressure, the combustion gases
can be drawn from the chimney and into the house. This condition is commonly referred to as downdrafting. Increased amounts of insulation, vinyl windows, extra caulking in various places and door
seals can all keep heat in but may also make a home too airtight. An easy way to stop negative
pressure in a home is to crack a window in the room containing the stove.
b) Environmental Conditions - High trees, low-lying house location such as in a valley, tall buildings or
structures surrounding your house and windy conditions can cause poor draft or down-drafting.
c) Cold Chimney Temperature - Avoid cold chimney temperatures by burning a hot re for the rst fteen
to forty minutes, being careful not to over-re the stove. If any part of the chimney or parts of the
stove start to glow, you are over-ring the stove. Where possible, install a temperature gauge on the
chimney so temperature drops can be seen.
d) Chimney Installation and Maintenance - Avoid using too many elbows or long horizontal runs. Too short
a chimney can cause difcult start-up, dirty glass, back smoking when door is open, and even reduced
heat output. Too tall a chimney may prompt excessive draft, which can result in very short burn times
and excessive heat output. If in doubt, contact a chimney expert and/or chimney manufacturer for
help. Clean chimney, rain caps and especially the spark arrestor regularly, to prevent creosote buildup, which will signicantly reduce chimney draw and possibly a chimney re.
Note: These instructions are intended as an aid and do not supercede any local, provincial or state
requirements. Check with ofcials or authorities having jurisdiction in your area.

Specifications
air control:
The primary air is controlled by the rod located on the right side of the unit. To increase your air, pull the
rod out and to decrease, push the rod in. All the units have a secondary air that ows through the tubes
at the top of the rebox, just below the bafes.
Pull this control all the way out when rst starting the
stove. Once the re has been established you may
adjust this control to set the burn rate of the re. For
optimal efciency, use a low to medium setting. If this
damper is closed at rst start-up, the re will burn very
slowly and could soot the appliance.
When shutting down the stove, fully open the air
control. This allows the chimney temperatures to
remain as high as possible for as long as possible. Cold
chimney temperatures create creosote.
