SAFETY INFORMATION
!WARNING
If the information in these instructions are not followed
exactly, a fire or explosion may result causing property
damage, personal injury or death.
Please read entire manual before you install and use your
heater.
- This heater can be very hot when burning.
- Combustible materials such as firewood, wet clothing, etc.
placed too close can catch fire.
- Children and pets must be kept from touching the heater when
it is hot.
- The chimney must be sound and free of cracks. Before
installing this unit, contact the local building or fire or other
authority having jurisdiction and follow their guidelines.
- Operate only with the doors tightly closed.
- Do not use an elevated grate or otherwise raise the fire.
- This heater is designed to burn natural wood only. Higher
efficiencies and lower emissions generally result when
burning air dried seasoned hardwoods, as compared to
softwoods or to green or freshly cut hardwoods.
- Do not start a fire with chemicals or fluids such as gasoline,
engine oil, etc.
- Do not burn treated wood, coal, charcoal, coloured paper,
cardboard, solvents or garbage.
- Do not let the heater become hot enough for any part to glow
red.

WARNING
• THIS APPLIANCE IS HOT WHEN OPERATED AND CAN CAUSE SEVERE BURNS IF CONTACTED.
• Do not operate appliance before reading and understanding operating instructions. Failure to operate appliance
according to operating instructions could cause fire or injury.
• Risk of burns. The appliance should be turned off and cooled before servicing.
• Do not operate without fully assembling all components.
• Do not install damaged, incomplete or substitute components.
• Risk of cuts and abrasions. Wear protective gloves and safety glasses during installation. Sheet metal edges
may be sharp.
• Young children should be carefully supervised when they are in the same room as the appliance. Toddlers,
young children and others may be susceptible to accidental contact burns. A physical barrier is recommended if
there are at risk individuals in the house. To restrict access to an appliance or stove, install an adjustable safety
gate to keep toddlers, young children and other at risk individuals out of the room and away from hot surfaces.
• Clothing or other flammable material should not be placed on or near the appliance.
• Due to high temperatures, the appliance should be located out of traffic and away from furniture and draperies.
• Ensure you have incorporated adequate safety measure to protect infants/toddlers from touching hot surfaces.
• Even after the appliance is out, the glass and/or screen will remain hot for an extended period of time.
• Check with your local hearth specialty dealer for safety screens and hearth guards to protect children from hot
surfaces. These screens and guards must be fastened to the floor.
• Any safety screen or guard removed for servicing must be replaced prior to operating the appliance.
• It is imperative that the control compartments, burners and circulating blower and its passageway in the appli-
ance and venting system are kept clean. The appliance and its venting system 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. The appliance area must be kept clear and free from combustible
materials, gasoline and other flammable vapors and liquids.
• Under no circumstances should this appliance be modified.
• Do not use this appliance if any part has been under water. Immediately call a qualified service technician to
inspect the appliance and to replace any part of the control system and any gas control which has been under
water.
• Do not operate the appliance with the glass door removed, cracked or broken. Replacement of the glass
should be done by a licensed or qualified service person.
• Do not strike or slam shut the appliance glass door.
• Only doors / optional fronts certified with the unit are to be installed on the appliance.
• Keep the packaging material out of reach of children and dispose of the material in a safe manner. As with all
plastic bags, these are not toys and should be kept away from children and infants.
• If the appliance is not properly installed, a house fire may result. Do not expose the appliance to the elements
(ex. rain, etc.) and keep the appliance dry at all times. Wet insulation will produce an odour when the appliance
is used.
• The chimney must be sound and free of cracks. Clean your chimney a minimum of twice a year and as re-
quired.
• The appliance is designed to burn natural wood only. Do not burn treated wood, coal, charcoal, coloured paper,
cardboard, solvents or garbage. This appliance has not been tested with an unvented gas log set. To reduce
risk of fire or injury, do not install an unvented gas log set into the appliance.
• Do not start a fire with chemicals or fluids such as gasoline, engine oil, etc.
• Operate only with the doors tightly closed.
• Do not let the appliance become hot enough for any part to glow red.
• Higher efficiencies and lower emissions generally result when burning air dried seasoned hardwoods, as com-
pared to softwoods or too green or freshly cut hardwoods. Burning wet unseasoned wood can cause excessive
creosote accumulation. When ignited it can cause a chimney fire that may result in a serious house fire.
• Do not use elevated grate or otherwise raise the fire.
• Do not store the wood within appliance installation clearances or within the space required for re-fueling and
ash removal.
• Your appliance requires periodic maintenance and cleaning. Failure to maintain your appliance may lead to
smoke spillage in your home.

WEAR GLOVES AND SAFETY GLASSES FOR PROTECTION.
KEEP HAND TOOLS IN GOOD CONDITION, SHARPEN CUTTING EDGES AND MAKE SURE TOOL HANDLES ARE
SECURE.
DO NOT USE MAKESHIFT COMPROMISES DURING INSTALLATION. DO NOT BLOCK OR RESTRICT AIR. DO NOT
IMPEDE AIR MOVEMENT ZONES MARKED “CLEARANCE TO COMBUSTIBLES”.
3.1 LOCATION AND CLEARANCES
For detailed clearance to combustibles, see Section 6.0 for plenum and consideration of venting location.
DO NOT INSTALL INTO ANY AREA HAVING A HEIGHT LESS THAN 7 FEET.
THIS APPLIANCE, CONFIGURED WITH ALL MODULES, WEIGHS 600 LBS (270 KG). ENSURE THERE IS
ADEQUATE FLOOR SUPPORT FOR THE APPLIANCE.
THE VERTICAL HEIGHT OF THE AIR INTAKE LINER MUST NOT BE GREATER THAN ⅔THE HEIGHT OF
THE CHIMNEY.
3.2 OUTSIDE COMBUSTION AIR
DO NOT DRAW AIR FROM GARAGE SPACES. EXHAUST PRODUCTS OF GASOLINE THE
COMBUSTION ENGINES ARE HAZARDOUS.
DO NOT DRAW AIR FROM ATTIC SPACES, BASEMENTS OR ABOVE THE ROOFING WHERE
OTHER HEATING APPLIANCES OR FANS AND CHIMNEYS EXHAUST OR UTILIZE AIR. THESE
PRECAUTIONS WILL REDUCE THE POSSIBILITY OF APPLIANCE SMOKING OR AIR FLOW
REVERSAL.
THE OUTSIDE AIR INLET MUST REMAIN CLEAR OF LEAVES, DEBRIS ICE AND/OR SNOW. IT MUST
BE UNRESTRICTED WHILE APPLIANCE IS IN USE TO PREVENT COMBUSTION AIR STARVATION
WHICH CAN CAUSE SMOKE SPILLAGE AND AN INABILITY TO MAINTAIN A FIRE. SMOKE SPILLAGE
CAN ALSO SET OFF SMOKE ALARMS.
NEGATIVE PRESSURE WITHIN YOUR HOME MAY INADVERTENTLY AFFECT YOUR APPLIANCE.
EXHAUST FANS SUCH AS BATHROOM FANS, RANGE HOODS AND CLOTHES DRYERS CAN
STRONGLY INFLUENCE NEGATIVE PRESSURE IN THE HOUSE.
AIR INLET TERMINALS MUST BE INSTALLED WITH ADEQUATE GROUND CLEARANCE AND BE
SUFFICIENTLY SHIELDED FROM PREVAILING WINDS TO PREVENT FROM REVERSING IN THE VENT
SYSTEM.

The Napoleon HMF150 may take outside combustion air directly into the appliance through a 4" inlet collar at
the back of the unit. This inlet is to supply combustion air for the HMF150 Wood Furnace only.
Secure and seal the intake liners to the collars using 3 sheet metal screws, and high temperature sealant.
Insulating the intake liners is recommended in colder climates to prevent condensation from occurring.
The 4" inlet can also draw combustion air from the room provided adequate make up air is available.
Fresh air makeup for the oil furnaces must follow criteria set in installation standard CSA B139-09 "Installation
Code For Oil Burning Equipment", and installed by a certified oil mechanic.
Fresh air makeup for gas fired furnaces must follow criteria set in installation standard CAN/CGA-B149.1 or
CAN/CGA-B149.2.
Fresh air makeup solid fuel furnaces must follow criteria set in installation standard CAN/CSA-B365.
WHEN INSTALLING A SYSTEM FOR MAKE UP FRESH AIR, THE INSTALLER MUST TAKE INTO
ACCOUNT A SATISFACTORY AIR MAKE UP RATE IN THE LIKELIHOOD THAT MORE THAN ONE
FUEL-BURNING FURNACE IN A MULTI FURNACE CONFIGURATION MAY OPERATE AT THE SAME
TIME.

REQUIRED COMPONENTS: • HMF150 Hybrid Furnace
• HMFK-ADDON Kit
• HMFK-SOLID or HMFK-GLASS Door Kit
THE INSTALLATION OF THE FURNACE MUST BE DONE IN ACCORDANCE WITH RULES OF
AUTHORITIES HAVING JURISDICTION AND THE CAN / CSA B365-01 (R2006) STANDARD FOR SOLID
FUEL BURNING APPLIANCES AND EQUIPMENT.
CAUTION
1. Certified for series connection to the supply plenum outlet only (upstream) of an oil-fired furnace or gas
fired furnace, or electric furnace;
2. May be added onto one of the following:
• an oil furnace having an oil input, as shown on the original nameplate, maximum firing rate 91,000
BTU/h
• a gas fired furnace having a gas input, as shown on the original nameplate, between 60,000 minimum
and 80,000 maximum BTU/h
• an electric furnace having a rating as shown on the original nameplate, between 15 minimum and 20
maximum KW
3. Do not connect duct work so that a reverse flow is possible;
4. Operate the original furnace (oil, gas, electric) unit periodically to ensure that it will operate satisfactorily
when needed;
5. Do not relocate, bypass or render inoperable any of the safety controls in the original furnace installation;
6. Maintain sufficient combustion-air supply to both furnaces. Air starvation is dangerous, see Section 3.2
"Outside Combustion Air";
7. Refer to manufacturer's instruction.
8. Do not use duct elbows having an inside radius of less than 150 mm (6 in).
9. An add-on unit shall only be installed on a furnace duct system and chimney that are in good operating
condition.
10. a) The differential static pressure between the inside and outside of the warm air supply plenum, or the
air-temperature rise at equilibrium across the original furnace is to be measured before any changes are
made to the system. Using the following methods the differential of pressure and temperature should be
adjusted to the same values after the add-on installation (meeting original manufacturer specifications)
in order to maintain the air flow through the original furnace.
• on a belt-driven system, blower pulleys and motor pulleys may be changed but the electrical current
flowing through the motor shall not exceed the nameplate rating (a blower motor of larger power
may be used);
• on a direct-drive system, the motor shall not be changed; however, the speed of the motor may be
increased;
