Safety Precautions
FOR SAFE INSTALLATION AND OPERATION OF YOUR “ENVIRO” WOOD
STOVE, PLEASE CAREFULLY READ THE FOLLOWING INFORMATION:
● Please read this entire manual before you install and use your new woodstove. Failure to
follow instructions may result in property damage, bodily injury or even death. Be aware
that local Codes and Regulations may override some items in this manual. Check with your
local inspector.
● If this appliance is not properly installed, operated and maintained, a serious house re could result.
Do not use any makeshift materials during installation, maintenance, or replacement.
● Never place wood, paper, furniture, drapes or other combustible materials near the stove. Do not let
children or pets touch it when it is hot.
● Operate only with the door and ash pan tightly closed and burn wood directly on the stove hearth. Do
not operate if the door glass is broken or a gasket is missing or damaged. Do not alter the combustion
air control valves. Dangerous overring could occur which could ignite creosote in the chimney or
cause a house re.
● At least 12 square inches (77.4 cm2) of fresh outside air should be admitted into the room or directly
to the stove through a 4 inch (10.16 cm) diameter pipe. For the stove to operate combustion-air must
be supplied through either the bottom or the back of the pedestal.
● Do not burn coal or charcoal as there is danger of carbon monoxide being produced. Do not use
chemical uids to start or re-fresh the re. Do not burn garbage or ammable uids such as gasoline,
grease, naphtha or engine oil. Never let the stove become hot enough to get any part red or glowing
red.
● Burning wet, unseasoned wood could cause excessive creosote accumulation in the ue pipe. When
ignited, it could cause a chimney re that could result in a serious house re.
● Do not use grates, andirons or any other methods to support or raise the re up off the hearth of the
appliance.
● This appliance is tested to ULC-S627 Standard for Space Heaters for Use with Solid Fuel, ULC-S628
Standard for Fireplace Inserts, & UL 1482 Standard for Safety for Solid-Fuel Type Room Heaters.
● Both the 1200 & 1700 Fireplace Inserts are approved for installed into a zero-clearance replaces in the
U.S. In Canada refer to local building or re ofcials for restrictions and installation inspection
● In Canada the existing chimney must be lined to the termination for all masonry installs.
IMPORTANT: The following must be done
to ensure proper operation. Failure to do so
will cause extreme overheating and possible
personal injury or property damage:
• If an outside air supply has not been added to
this appliance, please ensure that the 4” inch
fresh air outlet on the back of the pedestal is
removed.
• Ensure that the ash dump grate and cover
plate are installed over the ash dump hole.

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.
FANS:
All models have been approved for operation with or without the optional fans supplied by the
manufacturer. On medium or high burns, using a fan will increase the heat transfer slightly. Route the
power supply cord along the oor behind the stove where it will remain cool.
DISPOSAL OF ASHES:
If you let the ashes accumulate two or three inches on the oor they tend to burn themselves up.
The replace insert models do not have and ash drawer so the ashes will need to be scooped into a metal
container with a tightly tting lid. Place the closed container on a non-combustible oor, well away from
combustible materials.
The freestanding models are equipped with a small tap door in the rebox and an ash drawer. Open
4
the trap door located on the oor of
the unit. Push the ashes that have
accumulated into the hole were the
ashes would drop into the ash pan.
Ensure that the trap door is closed
properly before relighting the unit.
When the ash drawer is ready to be
emptied lift the front of the drawer up
then slowly pull the drawer straight out
and close the lid on the ash drawer
(see Figure 1); this is to prevent
making a mess with the ashes when
transporting the ash drawer through
the house. When re-installing the ash
drawer ensure that the lid is open and
line up the rails on the bottom of the
ash drawer with the notches in the
opening on the pedestal (see Figure 2).
Slide the drawer into place, the front of
the drawer will drop a bit when it is all
the way in.
If the ashes are to be buried in soil or
otherwise locally dispersed, keep them
in a closed container until all cinders
have cooled. Small amounts of cold
wood ash can be used in the garden
or compost.
Open Closed
Figure 1: Ash Drawer Lid Open and Close.
Figure 2: Installing Ash Drawer.

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 remove the door, open and lift. 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.
CLEANING THE PLATED SURFACES:
Painted faces should be wiped with a damp cloth periodically. If a plated door has been purchased, it
should be unpacked carefully to avoid getting anything on the surface of the nish, including cleaners,
polish and nger prints. It is important to note that ngerprints and other marks can leave a permanent
stain on plated nishes. To avoid this, give the face a quick wipe with denatured alcohol on
a soft cloth BEFORE lighting the replace. Never clean the door when it is hot. Do not use other
cleaners as they may leave a residue, which can become permanently etched into the surface.
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 devise 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
devise within the room; DO NOT REMOVE THE SMOKE DETECTOR FROM THE ROOM.
CREOSOTE - ITS FORMATION AND REMOVAL:
When wood is burned slowly, it may produce tar and other vapors that, combined with moisture, form
creosote. These vapors condense in the relatively cooler chimney ue of a slow burning re and, if
ignited, make an extremely hot re. Therefore, the smoke pipe and chimney should be inspected bi-
weekly during the heating season to determine if a build-up has occurred. If creosote has accumulated
it should be removed to reduce the risk of a chimney re.
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.

Operating Instructions
MAINTENANCE:
At the end of each heating season clean the chimney and the smoke pipe. If soot has accumulated above
the top bafe bricks, remove, clean, and then replace them. If the secondary air tube is badly eroded,
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.
BUILDING YOUR FIRE:
Proper operation of your stove will help to ensure safe, efcient heating. Please take a few moments to
review these simple operating procedures.
1. Fuel Selection:
This stove is designed to burn natural wood only. Higher efciencies and lower emissions generally
result when burning air-dried seasoned hardwoods, as compared to softwoods or to 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 catalytic 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.
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 efcient 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.

Operating Instructions
c) DO NOT OVERFIRE. If the heater or chimney connector glows, you are overring.
d) CAUTION: DO NOT PLACE FUEL WITHIN SPACE HEATER INSTALLATION CLEARANCES OR WITHIN
THE SPACE REQUIRED FOR CHARGING AND ASH REMOVAL.
4. For Maximum Efciency:
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 insufcient air for complete combustion, or a weak chimney draw.
Indeed, the cleanness of the glass is a good indicator of the stove operating efciently.
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,
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 sufcient
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

Operating Instructions
length for the logs used in the 1200 would be about 16“ (381 mm) but it can burn pieces up to 18” long.
Ideal length for the logs used in the 1700 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 signicantly 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 difcult 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
clean, but if you must clean the glass, use a soft cloth with no abrasive and clean only when 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 backpufng 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 efciency. 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

9
Operating Instructions
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 down-
drafting. 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 difcult 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 build-
up, which will signicantly 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 ofcials or authorities having jurisdiction in your area.
AIR CONTROL:
The air wash and pilot air (control the amount of air to the re) are 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 bafes.
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. 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.

Decrease air - push rod in
