INTRODUCTION
Take note that this furnace uses the same wood burning technology as a high efficiency
EPA certified wood burning furnace. This applies to the lighting, the ember bed, and the
minimum combustion air intake which was calibrated to burn good seasoned cordwood.
This model line is certified as meeting the emissions limits in 40 C.F.R. part 60, section
60.532 (B) per EPA methods 28 and 5G-3, February 1991.
Emissions: 6.6 g/h or 0.229 g/MJ
Average efficiency: 76 % (LHV) / 71% (HHV)
To optimize the efficiency of your furnace, here is some advice that you should follow
when installing or operating your Tundra furnace:
Respect the local codes (when in doubt, consult your local dealer);
Check the specifications on the certification label about the clearances. Make sure that
they correspond to those included in the instruction manual.
Make sure your furnace is installed according to the instructions on the certification
label;
The furnace is fully assembled at the factory and no electrical connection is required
other than plugging the power cord into an outlet. It does not include automatic variable
speed control of the fan. Factory connection is on speed 2 (medium-low) but can be
modified. The blower speed must conform to the recommendations of the Warm Air
Heating and Air Conditioning National Association and should respect the static
pressure ranges in the warm air plenum of the furnace (see section 2.1.2, General
technical data.
We recommend that our woodburning hearth products be installed and serviced by
professionals who are certified in the United States by NFI (National Fireplace
Institute®) or in Canada by WETT (Wood Energy Technical Training) or in Quebec by
APC (Association des Professionnels du Chauffage).

PART A - OPERATION AND MAINTENANCE
Please see Part B for installation instructions.
1 Safety information
1.1 Summary of operation and maintenance cautions and warnings
HOT WHILE IN OPERATION, KEEP CHILDREN, CLOTHING AND FURNITURE
AWAY. CONTACT MAY CAUSE SKIN BURNS. GLOVES MAY BE NEEDED FOR
FURNACE OPERATION.
USING A FURNACE WITH CRACKED OR BROKEN COMPONENTS, SUCH AS
GLASS OR FIREBRICKS OR BAFFLES MAY PRODUCE AN UNSAFE CONDITION
AND MAY DAMAGE THE FURNACE.
OPEN THE AIR CONTROL FULLY BEFORE OPENING FIRING DOOR.
OPERATE ONLY WITH DOOR FULLY CLOSED. IF DOOR IS LEFT PARTLY OPEN,
GAS AND FLAME MAY BE DRAWN OUT OF THE OPENING, CREATING RISKS
FROM BOTH FIRE AND SMOKE.
THIS FURNACE IS NOT DESIGNED TO BE USED WITH THE DOOR OPEN. THE
DOOR MAY BE OPEN ONLY DURING LIGHTING PROCEDURES OR RELOADING.
DO NOT LEAVE THE FURNACE UNATTENDED WHEN THE DOOR IS SLIGHTLY
OPENED DURING IGNITION. ALWAYS CLOSE THE DOOR AFTER IGNITION.
NEVER USE GASOLINE, GASOLINE-TYPE LANTERN FUEL (NAPHTHA), FUEL
OIL, MOTOR OIL, KEROSENE, CHARCOAL LIGHTER FLUID, OR SIMILAR
LIQUIDS OR AEROSOLS TO START OR ‘FRESHEN UP’ A FIRE IN THIS
FURNACE. KEEP ALL SUCH LIQUIDS OR AEROSOLS WELL AWAY FROM THE
FURNACE WHILE IT IS IN USE.
DO NOT STORE FUEL WITHIN HEATER MINIMUM INSTALLATION CLEARANCES.
BURN ONLY SEASONED NATURAL FIREWOOD.
DO NOT BURN:
oGARBAGE OF ANY KIND,
oCOAL OR CHARCOAL,
oTREATED, PAINTED OR COATED WOOD,
oPLYWOOD OR PARTICLE BOARD,
oFINE PAPER, COLORED PAPER OR CARDBOARD,
oSALT WATER DRIFTWOOD, OR
oRAILROAD TIES.
DO NOT ELEVATE THE FIRE BY USING A GRATE IN THIS FURNACE.

DO NOT INSTALL AN AUTOMATIC FEEDER ON THIS FURNACE.
DO NOT INSTALL A MANUAL DAMPER ON THIS FURNACE.
THIS APPLIANCE SHOULD BE MAINTAINED AND OPERATED AT ALL TIMES IN
ACCORDANCE WITH THESE INSTRUCTIONS.
1.2 Smoke detector
We highly recommend the use of a smoke detector. It must be installed at least 15 feet
(4.57 m) from the appliance in order to prevent undue triggering of the detector when
reloading.
1.3 Chimney fire
A Chimney fire will happen when the flame from an uncontrollable fire ignites the sooth
and creosote deposits in a neglected venting system. It will often happen when burning
cardboard, branches or small dry pieces of wood. The first signs of a chimney fire are:
1. A rumble.
2. Smoke pipe becomes extremely hot.
3. Sparks or even flames shoot out of the chimney
In the event of a chimney fire, first call your local fire department and water the roof
in the vicinity of the chimney.
Make sure that the furnace door and the air intake damper are closed (if need be, lower
the thermostat setting and CLOSE the barometric draft damper manually if one is installed.
In the event of uncontrollable fire (caused by wrongful operation or excessive chimney
draft), follow the same procedure as in a chimney fire but you must then OPEN the
barometric draft damper manually if one is installed.
1.4 Prolonged power outage
To reduce the risk of overheating during a prolonged power outage (more than 10
minutes), it is recommended damper is closed. If your furnace is equipped with the
optional filter, remove the air filter to improve the circulation of air around the combustion
chamber of the Tundra furnace. Do not load the furnace more than 50 percent of its
capacity to prevent the risk of overheating,
