INTRODUCTION

Thank you for purchasing the ECO-35 pellet stove. You are now prepared to burn wood in the most efficient, convenient way possible. To achieve the safest, most efficient and most enjoyable performance from your stove, you must do three things: 1) Install it properly; 2) Operate it correctly; and 3) Maintain it regularly. The purpose of this manual is to help you do all three.

PLEASE read this entire manual before installation and use of this pellet fuel-burning room heater. Failure to follow these instructions could result in property damage, bodily injury or even death.

Keep this manual handy for future reference.

Your ECO-35 has been independently tested to ASTM E1509-04 Standard Specification for room heaters, pellet fuel burning type 1, UL 2482-1998 and ULC-S627-00 Standard for Solid Fuel Room Heaters, Oregon Administrative Rules for Mobile Homes (814-23-900 through 814-23-909) and Installation as a Stove Heater. This pellet stove, when installed, must be electrically grounded in accordance with local codes, or in the absence of local codes, with the National Electrical Code,

ANSI/NFPA 70 and CSA-C22.1.

This appliance is designed specifically for use only with pelletized wood. It is designed for residential installation according to current national and local building codes as a freestanding room heater. It is also approved as a mobile home heater which is designed for connection to an outside combustion air source.

The stove will not operate using natural draft or without a power source for the blower systems and fuel feed system and must not be burned with any type of coal.

This stove is designed to provide the optimum proportions of fuel and air to the fire in order to burn free of smoke and soot. Any blockage of the air supply to or from the stove will seriously degrade its performance and will be evidenced by a smoking exhaust and a sooting window. For best operation, the ash content of the pellet fuel should be less than 1% and the calorific value approximately 8,200 BTU/LB. Avoid high ash content fuels because this will rapidly fill up the burn pot and eventually cut off the combustion air supply.

Commercial and industrial installations of the ECO-35 should not be used since operational control is often not well managed in these settings

To receive full warranty coverage, you will need to show evidence

of the date you purchased your unit. Keep your sales invoice. We also recommend that you register your warranty online at

www.drolet.ca

Registering your warranty online will help us track rapidly the

information we need on your unit.

SAFETY PRECAUTIONS

• Do not operate your stove if you

smell smoke coming from it. Turn it off, monitor it, and call your dealer. Do not unplug it.

• Never use gasoline, gasoline-type

lantern fuel, kerosene, charcoal lighter fluid, or similar liquids to start or “freshen up” a fire in this stove. Keep all such liquids well away from the stove while in use.

• Never block free airflow through the

open vents of the stove.

• Never try to repair or replace any

part of the stove unless instructions are given in this manual. All other work should be done by a trained technician.

• The stove will not operate during a

power outage. If an outage does occur, check the stove for smoke spillage and open a window if any smoke spills into the room.

• Disconnect the power cord before

performing any maintenance or repairs on the stove. NOTE: Turning the stove “off” does not disconnect all power from the stove.

• Do not unplug the stove if you

suspect a malfunction. Turn the stove off, periodically inspect it, and call your dealer.

• Keep foreign objects out of the hopper.

• Do not throw this manual away. This

manual has important operating and maintenance instructions that you will need at a later time. Always follow the instructions in this manual.

• Do not place clothing or other

flammable items on or near the stove.

• The viewing door must be closed and

latched during operation.

• Do not operate the stove if the flame

becomes dark and sooty or if the burnpot overfills with pellets. Turn the stove off, periodically inspect it, and call your dealer.

• Do not touch the hot surfaces of the

heater. Educate all children of the danger of a high temperature stove. Young children should be supervised when they are in the same room as the stove.

• If the stove is installed in a room without

air conditioning, or in an area where direct sunlight can shine on the unit, it is possible this can cause the temperature of the stove to rise to operational levels; one of the sensors could then make the stove start on its own. It is recommended that the stove be unplugged when not in use for extended amounts of time (i.e. during the summer months).

• Contact your local building officials to

obtain a permit and information on any installation restrictions or inspection requirements in your area. Notify your insurance company of this stove as well.

• This unit must be properly installed to

prevent the possibility of a house fire. The instructions must be strictly adhered to. Do not use makeshift methods or compromise in the installation.

• Allow the stove to cool before

carrying out any maintenance or cleaning. Ashes must be disposed in a metal container with a tight lid and placed on a non combustible surface well away from the home structure.

• This stove must be connected to a

standard 120 V., 60 Hz grounded electrical outlet. Do not use an adapter plug or sever the grounding plug. Do not route the electrical cord underneath, in front of, or over the stove.

• The exhaust system should be

checked, at a minimum, at least twice a year for any build up of soot or creosote.

• The exhaust system must be

completely airtight and properly installed. The pellet vent joints must be sealed with RTV 500°F. (260°C.) silicone sealant, and with UL-181-AP foil tape.

• Your stove requires periodic

maintenance and cleaning. Failure to maintain your stove may lead to smoke spillage in your home.

• This stove is designed and approved for

pelletized wood fuel only. Any other type of fuel burned in this heater will void the warranty and safety listing.

• When installed in a mobile home, the

stove must be bolted to the floor, have outside air, and NOT BE INSTALLED IN A BEDROOM (Per H.U.D. requirements). Check with local building officials.

• Stove Builder International Inc.

grants no warranty, implied or stated, for the installation or maintenance of your stove, and assumes no responsibility of any consequential damage(s).

COMBUSTION AIR SUPPLY

For a mobile home installation the stove must be connected to an outside source of combustion air. A 3” inside diameter metallic pipe, either flexible or rigid, may be attached to the inlet at the stove’s rear (refer to figures 4, 5 & 6). A rodent guard (minimum ¼” wire mesh) must be used at the terminus (refer to figure 5). All connections must be secured and airtight by either using the appropriately sized hose clamp and/or UL-181-AP foil tape.

For mobile home installations only: No combustion air supply may exceed 10 feet.

Sources of Outside Combustion Air

• A hole in the wall behind the stove.(Figure 5)

• A hole in floor near stove rear terminating only in a ventilated

crawl space.(Figure 6)

WHEN OUTSIDE AIR IS NOT USED

If outside air is not used, it is important that combustion air be easily available to the air inlet. A closable outside air register can be used in tightly insulated homes.

VENTING

The ECO-35 is certified for use with a vent certified to UL-103 or ULC S629M and a chimney type vent certified to UL-641 or ULC-S-609-M89 and ULC/ORD C441-M90, with 3” or 4” inner diameter. In Canada, we recommend that you use a listed pellet vent that meets the ULC S-609 M89 and ULC/ORD C441-M90 Standards. For the United States, we recommend that you use a listed pellet vent that meets the UL-641, 7 edition Standard. This unit can be vented in an existing chimney with the addition of a liner if the chimney is more than 4” in diameter. Class “A” chimney is not required. Refer to the instructions provided by the vent or chimney manufacturer, especially when passing through a wall, ceiling or roof.

COLLAR

Your venting system should have at least one foot of vertical rise for each foot of horizontal run. The total vertical rise should ne ver be less than 3 feet (see Appendix A).

This is a pressurized exhaust system. All vent connector joints must be sealed with 500°F (260°C) RTV silicone sealant to ensure consistent performance and avoid smoke spillage. All horizontal connector joints must be sealed with UL-181-AP foil tape. We recommend that all vertical vent connector joints be secured with a minimum of 3 screws.

DO NOT CONNECT THIS UNIT TO A CHIMNEY FLUE SERVING ANOTHER APPLIANCE.

DO NOT INSTALL A FLUE DAMPER IN THE EXHAUST VENTING SYSTEM OF THIS UNIT.

INSTALL VENT AT CLEARANCES SPECIFIED BY THE VENT MANUFACTURER.

EQUIVALENT VENT LENGHT (EVL)

The longer the run of pipe in your installation, the greater the restriction in the system. Therefore, larger diameter pipe should be used.

• Use 4” pipe if you have more than 15 feet of Equivalent Vent Length (EVL).

• Horizontal runs shall not exceed 10 feet of EVL.

• To calculate EVL, use the following conversions table:

Qty Type of pipe EVL equivalent(ft)

1 90° elbow or “T” 5

1 45° elbow 3

1 ft Horizontal pipe run 1

1 ft Vertical pipe run 0.5

NOTE: At altitudes above 3,000 feet, we suggest the use of 4” diameter vent at an EVL of 7 feet or more.

Here is an example on how to calculate the EVL of your installation. (See Figure 8)

(3 x 4’ of vertical length = 12’ x 0.5 = 6 EVL) + (1 x elbow or "T" = 5 EVL) + (2 x 1’ of horizontal length = 2 EVL)

Total EVL = (6 + 5 +2) = 13. So 3” diameter vent is acceptable.

INSTALLATION CONFIGURATIONS

HORIZONTALLY THROUGH WALL

(refer to Figure 7 & 8)

NOTE: Follow Vent chimney manufacturer’s instructions.

1. Position stove, adhering to clearances shown in Figures 1 & 2.

2. Locate position of hole in wall; directly behind stove exhaust vent (refer to figure 4).

3. Always maintain 3” clearance from combustible materials.

4. Install Vent wall thimble per Vent manufacturer’s instructions.

5. Attach enough piping to penetrate and extend at least 6” beyond exterior walls. An 8-foot vertical pipe run is suggested where possible to reduce the possibility of smoke spillage in the event of a loss of negative pressure.

6. Attach cap and seal outside wall thimbles with non-hardening waterproof mastic.

Termination should not be located so that hot exhaust gases can ignite trees, shrubs, or grasses or be a hazard to children. Exhaust gases can reach temperatures of 500ºF and cause serious burns if touched.

Mobile home installations must use a spark arrester. Other restrictions may apply, such as the need to maintain a minimum distance to a gas meter. US and Canadian Standards may vary. Consult the vent manufacturer’s instructions.

VERTICALLY WITH NEW CHIMNEY SYSTEM

(Refer to Figure 9 & 10 for basement installation)

NOTE: Follow Vent chimney manufacturer’s instructions. OPTION: To achieve a center vertical installation, a 45º elbow and a

clean-out tee can be used to offset the pipe from the exhaust outlet to the rear center of the stove.

OPTION: Install Vent elbow in place of clean-out tee. Locate stove. Drop plumb bob to center of tee outlet, mark point on ceiling. Install ceiling support and Vent pipe per Vent manufacturer’s instructions.

1. Always maintain 3” clearance from combustible materials. When passing through additional floors or ceilings, always install firestop spacer.

2. After lining up for hole in roof, cut either around or square hole in roof, always 3” larger all the way around pipe. Install upper edge and sides of flashing under roofing materials, nail to the roof along upper edge. Do not nail lower edge. Seal nail heads with non-hardening waterproof mastic.

3. Apply non-hardening, waterproof mastic where the storm collar will meet the vent. Slide storm collar down until it sits on the flashing. Seal and install cap. Mobile home installations must use a spark arrester.

VERTICALLY INTO EXISTING CHIMNEY SYSTEM

As an alternative, 3” or 4” Vent can be run inside existing chimney to termination(Figure 11). This is the preferred method.

Follow guidelines for equivalent vent length.
