CONGRATULATIONS!

You have just purchased one of the safest chimneys in North America. Designed with care, using the latest technology, it has been manufactured in accordance with ISO International Standards of Quality. The chimney is easy to install and all parts of the system are built to ﬁt perfectly with each other. If you’re handy, know how to use a few simple tools and have some basic carpentry skills, you can install your DURATECH CANADA (DTC) chimney yourself over one weekend. Or you can hire a professional to do the job.

BURNING SMART

How you burn wood in your stove or ﬁreplace directly affects the formation of creosote. Smaller, hotter ﬁres are better than large, smouldering ones. Fast, effective start ups are important, as is the moisture content of the wood. Ideally, you should use seasoned wood with a moisture content of 20 25%. A surface thermometer is an excellent investment. Properly seasoned wood can produce 8,600 BTUs per pound.

APPLICATIONS

WOOD AND COAL STOVES

DURATECH CANADA (DTC) chimney has been designed for use with wood, gas, oil and coal in residential, commercial and industrial applications.

WARNING

A MAJOR CAUSE OF CHIMNEY-RELATED FIRES IS FAILURE TO MAINTAIN REQUIRED CLEARANCES (AIR SPACES) TO COMBUSTIBLE MATERIALS. IT IS OF UTMOST IMPORTANCE THAT THIS CHIMNEY BE INSTALLED ONLY IN ACCORDANCE WITH THESE INSTRUCTIONS.

RECOMMENDATIONS Clearance

The clearances stated in this guide are minimum requirements: if more space is available, use it. Minimum clearances mean leaving unobstructed air space. Do not ﬁll these spaces with any material whatsoever, especially not insulating material. If you insulate your attic later, be sure to maintain the necessary clearance.

Inspection

Contact local building or ﬁre ofﬁcials about restrictions, installation inspection and permit that may be required in your area.

Replacement Parts

If a component of your chimney system is damaged it must be replaced by an identical one from Duravent.

NOT ALL WOOD IS CREATED EQUAL

Some types of wood have greater energy potential than others. Some logs will give you a hot, crackling ﬁre, others will burn longer and more evenly. Choose the type of ﬂame you prefer. The following table shows how different types of wood burn.

Qualities

Table 1

DURATECH CANADA (DTC) has been listed to ULC-S629 , 2100 F in diameter 6,7 and 8 inches for wood/coal application . Note that for interior enclosed installation, premium shield are required around the chimney. Refer to speciﬁc Canadian installation section for proper installation.

DURATECH CANADA (DTC) is also designed for use with gas or oil ﬁred heating appliances such as furnace, hot water heaters and other appliances, as per ULC-S604 standards in diameter 5 to 10 inches. In these types of installations, no premium shields are required even where the chimney is enclosed.

If you are planning to install a wood stove, we recommend that you:

1. Choose a stove that bears the label of a testing laboratory (such as UL, CSA, WH, ULC or ICBO).

2. Choose the right size stove. Do not buy one larger than you need.

3. Connect only one appliance to a chimney.

4. Never overﬁre your stove. If any part of the stove or stove pipe is glowing red, then you are overﬁring. Immediately close the stove’s dampers until the system cools. The high temperature caused by overﬁring can permanently damage the stove and stove pipe and may overheat nearby combustible walls and furniture.

5. Install the stove and stove pipe as described in the installation instructions accompanying the stove. Be certain to maintain the required clearances to combustible construction.

6. Keep your ﬂue gases between 300°F and 500°F. This will maximize efﬁciency while minimizing condensation and creosote formation. Do not ﬁll your stove with wood and allow it to smoulder for 8 to 10 hours. This condition produces large amounts of creosote in the chimney.

7. Do not burn sea driftwood or treated wood. These combustibles are highly corrosive to all types of stainless steel.

FACTORY BUILT FIREPLACE

DURATECH CANADA (DTC) in Canada is also suitable for use with closed or opened certiﬁed ﬁreplaces.

Note that the premium shields are normally not required for factorybuilt ﬁreplace installation, including interior chase.

When doing so please refer to the ﬁreplace installation instructions to install the chimney.

KEEP YOUR CHIMNEY CLEAN SIZING CHART

CHIMNEY OPERATION AND MAINTENANCE

Wood stoves can quickly create large deposits of creosote in the chimney. Some wood stoves can create enough creosote in two weeks to cause a chimney ﬁre. When using a wood stove, we recommend that you:

1. Initially inspect the chimney system weekly. From this, you will learn how often it will be necessary to clean your chimney.

2. The chimney should be inspected at least once every 2 months during the heating season to determine if a creosote or soot build-up has occurred: if creosote or soot has accumulated, it should be removed to reduce the risk of chimney ﬁre.

3. Have your chimney cleaned by a qualiﬁed chimney sweep. If you want to clean your chimney yourself: clean your chimney using plastic, wood or stainless steel brushes. Do not use a brush that will scratch the stainless steel interior of your chimney.

4. Do not expect chemical chimney cleaners to keep your chimney clean. Their use does not negate the necessity of periodically inspecting and cleaning your chimney.

CHIMNEY FIRES

If you are having a chimney ﬁre, follow these steps:

1. Close all heater doors and combustion air controls. For ﬁreplaces, block the ﬁreplace opening with a non-combustible material (such as a steel sheet).

2. Alert your family to the possible danger.

3. If you require assistance, alert your ﬁre department.

4. If possible, use a dry chemical ﬁre extinguisher, baking soda or sand to control the ﬁre. Do not use water as it may cause a dangerous steam explosion.

5. Watch for smouldering or ﬁre on combustibles next to the stove, stove pipe and chimney. Check outside to ensure that sparks and hot embers coming out of the chimney are not igniting the roof.

6. Do not use the stove again until your chimney and stove pipe have been inspected by a qualiﬁed chimney sweep or Fire Department Inspector.

DURATECH DTC chimney has been designed to withstand the intense heat of a chimney ﬁre. Nevertheless chimney ﬁres are dangerous and should be prevented.

BEFORE HIRING A CHIMNEY SWEEP

1. Does the company or individual have adequate liability insurance in case of damage?

2. How long has the company been in business?

3. Does the company offer current references?

4. Is the company involved in any unresolved disputes?

GENERAL INSTALLATION NOTES

INSTALLATION NOTES

1. The chimney is intended for use with solid (6’’,7’’,8’’ dia. only) or liquid and gaseous fuel burning appliances.(all diameters)

Allowable ﬂue gas temperature: Maximum continuous 540°C (1000°F) Brief forced ﬁring 760°C (1400°F)

Tested to 1150°C (2100°F) - 30 minutes

2. On wood or coal stove application and in area where the chimney

is completely enclosed, it is required to install Premium shields (telescopic of ﬂexible) around the chimney and a Radiation shield connector at the ceiling level.

For venting of gas or oil burning appliances Premium shields are

not required even where the chimney is enclosed.

For factory-built wood burning ﬁreplaces, Premium shields

are usually not required, please follow ﬁreplace installation instruction.

3. The maximum height of chimney supported by the various supports are outlined on page 3.

4. The supports described in this booklet should only be used with Duravent model DURATECH CANADA (DTC), 5", 6", 7", 8" and 10" factory built chimneys.

5. Size the chimney in accordance with the appliance manufacturer's instructions.

6. When a ﬁrestop (DTC-FS , DTC-ISI or DTC-RSCI) needs to be installed, it is important to follow the opening dimensions for the ﬂoor openings prescribed in this manual. This way, the holes left by the folded positioning tab of the ﬁrestop will be blocked by the ceiling.

7. A chimney servicing a ﬁreplace or an incinerator shall not serve any other appliance.

8. The chimney shall extend at least 3 ft above its point of contact with the roof and at least 2 ft higher than any wall, roof or adjacent building within 10 ft of it.

9. The maximum height of unguided chimney above the roof is 5 ft.

10. The clearance between single wall pipe and unprotected combustible material must not be less than 18" (see national building code and NFPA 211) except: The distance between the vertical stove pipe and the ceiling may be less than 18" and will be established by the ﬁnish support.

11. Portions of the chimney which may extend through accessible spaces shall be enclosed in all cases to avoid personal contact with the chimney and damage to the chimney. When doing so on woodstove or coal application, a telescopic or ﬂexible Premium shield must be installed (see Figure 2). Except for installation in single and two-story family dwellings, the enclosure must have a ﬁre resistance rating equal to or greater than that of the ﬂoor or roof assemblies through which they pass.

12. Do not ﬁll the 2" space around the chimney with insulation or any other material. Insulation placed in this area could cause adjacent combustibles to overheat.

13. Self tapping screws are not required, but may be used to reinforce the connection and avoid accidental unlocking of chimney lengths.

FOR UNENCLOSED INSTALLATION OR VENTING OF OIL OR GAS APPLIANCES:

Refer to interior installation on a furnace and water heater guideline (page 12).

FOR ENCLOSED INSTALLATION (6’’,7’’,8’’ dia. only) (woodstove or coal burning appliance):

- Lock the ﬁrst chimney length into the support with the male coupling on top.

- Slide a Telescopic Rigid shield (DTC-TRS) on top of that length all the way to the bottom.

Stack the next chimney length on the ﬁrst length. Be sure that the male and female threads are not in line when putting the lengths together. Turn the chimney clockwise to lock it in place. You may add a 1/2 in stainless steel self tapping screw to prevent accidental unlocking.

Continue installing until the required chimney reached the attic level.

- At the ceiling level, install a Radiation Shield Connector (DTC-RSCI) and a Radiation Shield Firestop (DTC-FRSC) (Figure 5)to the chimney.

Slide the Radiation Shield Connector down until the bottom of the insulated tube passes just through the Radiation Shield Firestop as shown in Figure 4. Adjust the height until a minimum of (1”) of the Radiation Shield Connector passes throught the ﬁrestop below. Once you are satisﬁed with positioning of the Radiation Shield Connector, passes throught the ﬁrestop below. Fix it to the chimney from the attic side using 3 self-tapping screws.

The Telescopic Shield is then slid upwards to the ceiling and attached to the bottom of the Radiation Shield Connector using 3 self-tapping screws.

In the attic:

• If the chimney is not enclosed in the attic, a storm collar (DTC-SC) must be installed on top of radiation Shield to prevent any loose insulation from falling in the area between the chimney and the support.

• If the chimney is to be enclosed within the attic, continue installed chimney sections up through the roof opening.Lower another Telescopic
