VENTING
This model must have a vent opening in the rear of the unit. Confirm this and also
check that the label on the right side panel door states "Vented Room Heater".
WARNING: THIS APPLIANCE HAS BEEN DESIGNED TO OPERATE BY DRAWING COMBUSTION AIR
AND DILUTION AIR FROM THE ROOM. THE DRAFT HOOD LOCATED IN THE SAME ATMOSPHERIC
PRESSURE ZONE AS THE COMBUSTION AIR INLET TO THE APPLIANCE. IT IS ALSO DESIGNED TO
DRAW ROOM AIR FOR PROPER HEAT CIRCULATION FROM THE REAR OF THE UNIT. BLOCKING OR
MODIFYING THE LOUVERS IN ANY WAY CAN CREATE HAZARDOUS SITUATIONS, EITHER THROUGH
POOR VENTING OR BY OVERHEATING. IT IS IMPORTANT THAT THIS UNIT HAS SUFFICIENT AIR
CIRCULATION FOR PROPER VENTING AND COMBUSTION THUS PROVISIONS MUST BE MADE FOR THE
SUPPLY OF ADEQUATE COMBUSTION AND VENTILATION AIR.
WARNING: Operation of this heater when not connected to a properly installed and maintained venting
system or tampering with the vent safety shutoff system can result in carbon monoxide (CO) poisoning
and possible death.
THE APPLIANCE CANNOT BE CONNECTED TO A CHIMNEY FLUE SERVICING A SEPARATE SOLID FUEL
BURNING APPLIANCE.
FLUE GAS SPILL SWITCH
NOTE: THIS HEATER MUST BE PROPERLY CONNECTED TO A VENTING SYSTEM. THIS HEATER
IS EQUIPPED WITH A VENT SAFETY SHUTOFF SYSTEM DESIGNED TO PROTECT AGAINST
IMPROPER VENTING OF COMBUSTION PRODUCTS. THIS SAFETY SWITCH IS LOCATED ON THE
REAR OF THE APPLIANCE CLOSE TO THE DRAFT HOOD RELIEF OPENING.
IF THE SWITCH TRIPS MORE THAN ONCE, THE CHIMNEY SHOULD BE INSPECTED BY A
QUALIFIED SERVICE TECHNICIAN FOR POSSIBLE BLOCKAGE OR SEVERE DOWN DRAUGHT
CONDITIONS
This stove should be vented by certified 4" Type B Gas Vent or a flexible gas vent liner, which may be encased in
6” decorative, stove pipe. The flue collar of the appliance will fit inside of standard vent and may be fastened
directly to the vent.
The ENVIRO incorporates its own internal draft hood, so no additional external draft hood is required.
Check periodically that the vent is unrestricted and an adequate draft is present when the unit is in operation.
The venting system should be assembled and installed according to the vent manufacturer's instructions and the
local, state/provincial or national codes. Two basic venting configurations are shown as rough guidelines only.
Follow national and local codes for other installation options.
6

A. USING AN EXISTING CHIMNEY
• Measure the height of the chimney beforehand and purchase the
appropriate kit. Never attempt to over stretch a flexible liner to
accommodate the height of the chimney.
• Any flue damper must be removed or locked permanently in the
open position.
• The chimney must be clean, in good working order and constructed
out of non-combustible materials.
• Make sure that all chimney clean-outs are tightly fitting and will not
permit air to leak into the chimney.
• Make all gas connections and check for leaks.
See vent manufacturer's instructions for vent system clearances to
combustibles and vent terminal clearance from roof.
MANUFACTURERS GENERAL VENTING
GUIDELINES
This information is compiled by the manufacturer as a very general rule for
single appliance venting of the EG 28 gas stove with 4" Type B gas vent.
Venting code and regulations may vary from area to area, please check with
the local, state/provincial codes regarding the suitability of your application.
For other special venting requirements, please refer to the local, state/provincial or national codes.
For best venting performance, we recommend total vent height of 10
ft (3m) to 30 ft (9m). Total horizontal length depends on the number
of elbows used. The venting
Should never slope down. 1/4" rise per 2' horizontal is
recommended.
If practical, it is best to locate the appliance to permit the use of
shorter horizontals and fewer elbows.
-Two 90°elbows, maximum total horizontal length of 20 ft (6m).
-Three 90°elbows, maximum total horizontal length of 13 ft (3.8m).
-Four 90°elbows, maximum total horizontal length of 6 ft (1.9m).
-Five 90°elbows, maximum total horizontal length of 0 ft (0m).
If 45°elbows are used, one 90°elbow is equivalent to two 45°
elbows.
Venting rise should be a minimum of 1 ft (.31m).from the top of the
unit before any horizontal run.
The bottom of the vent cap shall extend at least 2 ft. (.6m) above the
highest point of the roof where it passes through and at least 2 ft
(.6m) higher than any portion of the roof within a horizontal distance
of 10 ft. (3m).

INSTALLATION OF LOG SET and EMBERS
INSTALLING THE GLOWING EMBERS
A bag of Rock Wool embers is provided for use on the burner tray.
CAUTION: Use only the type of ember material supplied with this appliance. Due to the irregular size of the
ember material there may be more than required.
If over time, through cleaning and servicing, these embers require replacement, contact the nearest ENVIRO
dealer for replacement embers.
Remove the ember material from the plastic bag.
Cover the shaded areas in the diagram shown beside.
Totally fill these areas with glowing ember material
Do not pack embers down on burner. Leave embers
loose.
CAUTION: NEVER OPERATE THIS APPLIANCE WITH THE DOOR REMOVED
INSTALLING THE LOGSET
Carefully remove logs from box. Check to ensure there is no damage. It is very important to install the logs in their
proper position to insure safe, optimum operating conditions.
1. Open the front door.
2. Place each piece of the log set into
the firebox resting the pins in the
holes in the logs.
3. Close the door and tighten securely.
Upon the first light up, watch for ignition to
all burner ports. If a long delay is noted:
a) First, wait for the appliance to cool
down
b) Open the front door of the appliance.
(See adjusting the venturi section to adjust air for proper flame).
IMPRTANT NOTE: When the unit is turned on for the first time, it should be turned onto high without the fan on for the
first 4 hours. This will cure the paint, logs, gasket material and the other products used in the manufacturing process. It is
advisable to open a window or door, as the unit will start to smoke and can irritate some people. After the unit has gone
through the first burn turn the unit off including the pilot, let the unit get cold then remove the glass door and clean it with a
good gas fireplace glass cleaner, available at your local ENVIRO dealer. (See page 10 glass cleaning.

MAINTENANCE AND TECHNICAL
Annually check to ensure that your
Venting system is clear.
Periodically check the pilot and burner. Check to
see that all the burner ports are clean and clear.
Check the pilot head for blockage. Check to ensure
the pilot flame is blue with small yellow tips.
CLEANING OF GLASS
Do not clean glass when hot
It will be necessary to clean the ceramic glass
periodically. During a cold start up, condensation
will sometimes form on the glass; this is a normal
condition with all gas fireplaces and stoves.
However, this condensation can allow dust and lint
to cling to the glass surface. Initial paint curing of the
appliance can leave behind a slight film on the glass.
This is a temporary problem. It is therefore
recommended that the glass be cleaned initially after
about the first two weeks of use.
After that, depending upon the amount of use,
cleaning should be required no more than two or
three times per season.
To clean the door, use a mild glass cleaner and a
soft cloth. Abrasive cleaners will damage the glass
and gold surfaces.
OPENING THE DOOR
Turn unit off and wait until the appliance has cooled
down.
1. Open the right hand hinged side flap, which will
expose a door fastener. Using a 1/2" wrench,
loosen the fastener.
1. Due to the shape of the bay window door. You
must also open the left-hand side flap before
attempting to open the door.
3. Ensure the door is properly fastened after
cleaning before attempting to re-light the appliance.
TO REPLACE DOOR AND GLASS ASSEMBLY
The glass in this appliance is an integral part of the
door assembly. If the glass is damaged or broken a
replacement door assembly including glass must be
fitted.
To Replace:
• Open door fully
• Lift door vertically so that hinge pins lift out of
hinge receivers.
• Return the door assembly to dealer.
The door and glass assembly must be replaced
as a complete unit. By your ENVIRO Dealer.
No substitute materials are allowed.
Use extreme caution cleaning up broken glass. Use
thick gloves and broom to brush glass up.
FOR CLEANING THE INSIDE OF THE FIREBOX
Remove the logs carefully from the firebox. Gently
remove the embers and place on a piece of paper
towel, until ready to replace.
Vacuum the firebox thoroughly. Carefully clean off
any dust on the logs and remove any lint from the
main burner and pilot burner.
After carefully replacing the log and embers in their
correct positions, and the door has been resealed,
re-light the pilot, following the instructions on the
attached label.
CLEARANCES MUST BE SUFFICIENT TO ALLOW
