SAFETY PRECAUTIONS
FOR SAFE INSTALLATION AND OPERATION OF YOUR "ENVIROGAS" ROOM HEATER, PLEASE, CAREFULLY
READ THE FOLLOWING INFORMATION:
• All "ENVIROGAS" gas-fired appliances must be
installed in accordance with these instructions.
Carefully read all the instructions in this manual first.
Consult the building authority having jurisdiction to
determine the need for a permit prior to commencing
the installation.
• NOTE Failure to follow these instructions could
cause a malfunction of the fireplace that could result
in death, serious bodily injury, and/or property
damage.
• Failure to follow these instructions may also void
your fire insurance and/or warranty.
GENERAL
• Installation and repair should be done by a
qualified service person. The appliance
should be inspected before use and at least
annually by a qualified service person. More
frequent cleaning may be required due to
excessive lint from carpeting, bedding
material, etc. It is imperative that control
compartments, burners and circulating air
passageways of the appliance be kept clean.
• Due to high temperatures the appliance
should be located out of high traffic areas
and away from furniture and draperies.
Children and adults should be alerted to
hazards of high surface temperatures and
should stay away to avoid burns or clothing
ignition.
• Young children should be carefully
supervised when they are in the same room
as the appliance.

dangerous operation. Verify proper operation after servicing.
FAN INSTALLATION
OPTIONAL FAN
Efficiency and heat output of the unit increases with the operation of the fan.
• This appliance is equipped with a three-prong (grounding) plug for your protection against shock hazard, and should be plugged
directly into a properly grounded three-prong outlet. DO NOT cut or remove the grounding prong from this plug.
The appliance, when installed with optional blower , must be electrically connected and grounded in accordance with local codes or in
the absence of local codes, with the current CSA C22.1 CANADIAN ELECTRICAL CODE Part 1, SAFETY STANDARDS FOR

7. GAS LINE CONNECTION AND TESTING
WARNING: Only persons licensed to work with gas piping can make the gas connections to this appliance.
This appliance is equipped with a 3/8” stainless steel flex line from the valve. This line may be routed through the hole in the rear
of the pedestal, or on inserts, routed through the fire box sides. An adapter plate is available for installations that do not allow flex pipe
through cabinetry.
NOTE: Consult your local authorities and in CAN. the CAN/CGA-B149 (1 or 2) Installation Code, For USA gas installations follow either
local codes or the current edition of the National Fuel Gas Code ANSI. Z223.1.
The appliance and its shutoff valves must be disconnected from the gas supply piping system during any pressure testing where the
pressure exceeds 1/2 PSIG (3.45 kPa) or damage will occur to the valve.
The appliance must be isolated from the gas supply piping system by closing its individual manual shutoff valve during any pressure
testing of the gas supply piping system at test pressures equal to or less than 1/2 psig (3.5 kPa).
Always check for gas leaks with a soap and water solution or an approved manner after completing required pressure tests.

8. VENTING
WARNING: THIS APPLIANCE HAS BEEN DESIGNED TO OPERATE BY DRAWING COMBUSTION AIR AND
DILUTION AIR FROM THE ROOM. IT IS ALSO DESIGNED TO DRAW ROOM AIR FOR PROPER HEAT
CIRCULATION FROM THE SIDES 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. PROVISIONS MUST BE MADE FOR THE SUPPLY OF ADEQUATE COMBUSTION AND
VENTILATION AIR. THESE OPENINGS MUST NOT BE BLOCKED.
THE APPLIANCE MUST NOT BE CONNECTED TO A CHIMNEY FLUE SERVICING
A SEPARATE SOLID FUEL BURNING APPLIANCE.
AUTOMATIC 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 VENTING SHOULD BE INSPECTED BY A QUALIFIED
SERVICE TECHNICIAN FOR POSSIBLE BLOCKAGE OR SEVERE DOWN DRAFT CONDITIONS
This stove can be vented with aluminum or stainless steel flex vent and/or certified 4" Type B Gas Vent. The
flue collar of the appliance will fit inside of a standard 4” vent and may be fastened directly to the vent.
Check periodically that the vent is unrestricted and an adequate draft is present when the unit is in operation.
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.
A. VENTING FIREPLACE INSERTS
The ENVIROGAS 828 insert may be installed and vented into
any solid fuel fireplace that has been installed in accordance
with the National, Provincial/State and local building codes and
has been constructed of non-combustible materials.
An approved 4" chimney liner, throat connector, and rain cap
must be installed, to ensure a tight seal, top performance,
safety
and efficiency. Carefully follow the manufacturers instructions
which accompany the chimney liner kit.
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.
Install sealed throat connector to prevent leakage of room air
through chimney.
Any flue damper must be removed or blocked permanently in
the open position.
The chimney must be clean, in good working order and
