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.

INTERIOR INSTALLATION WITH CATHEDRAL CEILING

A - CATHEDRAL SUPPORT (DTC-RCSC)

This support is designed to be used in rooms with cathedral ceilings (no attic space between the ceiling and the roof). If the support is used as a regular ﬂoor support, follow the instructions for the ﬁnish support DTC-FSC on page 5.

Step 1. Situate the chimney in a convenient location as near as possible

to the appliance outlet. Cut and frame a hole in the roof for the support. The sides of this hole must be vertical (ﬁgure 7) (see

table 3 on page 3).

Step 2. From above, place the support in the opening. Lower it to a

convenient height.

Note: The cone portion of the support must extend below the

ceiling. The minimum horizontal distance between the single wall stove pipe and the ceiling is 18".

Using a level, make sure the support is vertical. If the support

extends above the roof, cut it ﬂush with the top of the roof. Nail the support to the framed opening using (12)-3" spiral nails (ﬁgure 8).

INSTALLATION INSTRUCTIONS

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 1/2in stainless steel self tapping screw to prevent accidental unlocking. When you reach the height at which the elbow will be installed:

Step 1. Install the insulated offset elbow on the vertical chimney length.

Turn it in the required direction and fasten it to the chimney with the (4)-1/2" metal screws provided.

Step 2. Place the required offset chimney length (see chart below) on

the elbow. Turn it clockwise to lock it in place.

Step 3. Use another elbow to turn the chimney vertically. Again secure

the elbow to the chimney length using the (4)-1/2’’ metal screws.

For Enclosed installation (6", 7", and 8" dia. only) (woodstove or coal burning appliance)

- Place the ﬁrst chimney length on a ﬂat surface with the male coupling on top.

- Slide a ﬂexible shield (DTC-FLXS) on top of that length all the way to the bottom.

- Attach the ﬂexible shield to the section using 3 x 1/2" stainless steel self tapping screws.

- Slide this assembly in the support and turn clockwise to lock it in place.

- At the ceiling level from the top, install a Radiation Shield Connector (DTC-RSCI) and a Radiation Shield Support (DTC-FRSCS). Attach but not tighten together yet (see Figure 13).

Slide the Radiation Shield Connector down until the bottom of the insulated tube exceed the bottom of ceiling.

Adjust the height until a minimum of (1”) of the Radiation Shield Connector exceed the bottom of ceiling ( see Figure 11) 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.

When you reach the height at which the elbow will be installed:

Step 1. Install the insulated offset elbow on the vertical chimney length.

Turn it in the required direction and fasten it to the chimney with the (4)-1/2’ metal screws provided.

Step 2. Place the required offset chimney length (see table 8) on the

elbow. Turn it clockwise to lock it in place.

Step 3. Use another elbow to turn the chimney vertically. Again secure

the elbow to the chimney length using the (4)-1/2" metal screws.

Attach a spacer spring around the chimney at each elbow to help keep the ﬂexible shield centered. (See ﬁgure 11) Slide the ﬂexible shield up

the chimney and attach it below the ceiling to the Support Radiation Shield using 3 self tapping metal screws. If you are limited in space to screw, install a Swivel Adaptor (DTC-SA) (ﬁgure 11) below the Shield Connector (DTC-RSCI) and one on the top end of the ﬂexible shield.

If you are venting a Factory built ﬁreplace or an oil or gas burning appliance please refer to installation notes #2 (on page 5) for guidelines on the use of the Premium shields.

For Unenclosed installation or venting of oil or gas appliances:

Put the ﬁrst chimney length in the support. Turn it clockwise to lock it in place.

Note: the male coupling must be on top.

In the attic:

• Fix the radiation shield to the chimney and tight the support collar.

• 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 Shield through the roof opening down onto the Radiation Shield Connector.Adjust the height of the shield`s tube so it terminates just above the roof opening but under the ﬂashing.Once satisﬁed with positioning, secure both ends of the shield using self-tapping screws.

ROOF SUPPORT (DTC-RS)

Figure 14

The roof support has three possible uses: It may be used to support a chimney from the roof. It adjusts to any

roof pitch. It may be used on a ﬂoor, ceiling or roof above an offset to support the

chimney above the offset. It may be used on a ﬂoor, ceiling or roof as a supplementary support when

the chimney height exceeds that of the primary support. (See maximum

length height supported, page 3).

INSTALLATION INSTRUCTIONS

With the chimney extending through the hole in the roof, ceiling or ﬂoor and the radiation shield in place, proceed as follows (Refer to ﬁgure 15 for visual references):

Step 1. Assemble the support collar to ﬁt your chimney diameter, as

described on the instruction sheet supplied with the support.

Step 2. Slip the support down over the stainless steel chimney until its

brackets rest on the roof or ﬂoor. Tighten the collar around the chimney, then secure it by screwing the four 1/2" metal screws (supplied) through the holes located on each side of the collar bolts and into the chimney (Figure 32).

Step 3. Center the chimney and nail or screw the support to the roof or

ﬂoor using (8) - 2-1/2" nails or (8) N°8 - 1-1/4" wood screws. (ﬁgure 14).

INSTALLATION NOTES

If possible, install an interior chimney as it will provide better performance than an exterior chimney. In areas with continuous temperatures below

-18°C (0°F), the use of an exterior chimney may result in operating problems such as poor draft, excessive condensation of combustion products and rapid accumulation of creosote when connected to a wood burning appliance. If you do install an exterior chimney, we recommend that you enclose it using an insulated enclosure.

1. The chimney may be enclosed or unenclosed. If enclosed at 2’’

clearance all around the chimney on a wood stove application, a Premium shield must be installed around the chimney (Figure 19).

2. Maintain 2" clearance to combustible materials. Do not ﬁll the 2" space around the chimney with insulation or any other material.

3. A wall band must be used to secure the chimney to the wall. Maximum distance between wall bands is 8 feet.

4. The minimum length of chimney extending past the inside wall is 5 inches.

5. The maximum length of chimney extending past the inside wall is 24 inches.

6. The distance between the stove pipe and a parallel combustible wall or ceiling must not be less than 18". The distance between the horizontal stove pipe and the unshielded vertical wall through which it passes must not be less than 7 inches.

7. If an exterior installation is to be enclosed, allow for access to base of tee to facilitate required cleaning.

8. The minimum distance between the bottom of the support and any

horizontal combustible (including the ground) is 6". This distance can be reduced to 2 inches by using an insulated tee cap (DTC-TCI) in conjunction with a (DTC-TSA) wall support.

9. The adjustable support (DTC-TSA) may only be installed with an insulated tee cap (DTC-TCI) or a drain tee cap (DTC-TCD).

INSTALLATION INSTRUCTIONS STEPS

Figure 17

Determine where the chimney will pass through the wall.

• For concrete walls cut a hole slightly larger than the chimney.

• For combustible walls cut and frame a hole 4" larger than the chimney, midway between the wall studs (see table below for sizing).

Normally wall studs are placed at 16" centers. With the hole midway between them, the support will fasten to these studs and thus ensure a strong attachment to the wall. (see Figure 17).

Wood walls: from outside, put the square wall thimble (DTC-WTI) in the hole. Nail in place using (4) 2’’ nails or 1’’ screws. This wall thimble is adjustable from 7’’ to 12’’. From inside, wrap the insulation pad around the tube of the square wall thimble previously installed. Place the metal sheet around the insulation pad and close it by joining the staples at each end of the metal sheet together. Make sure the gap is completely ﬁlled in from inside to outside (cut insulation pad to proper length).

FOR UNENCLOSED INSTALLATION OR VENTING OF OIL

OR GAS APPLIANCES:

Continue until the required chimney height is reached.

NOTE: At 8' intervals, attach the chimney to the wall using a wall band (DTC-WSU).

If the chimney passes through the roof, cut a hole large enough to provide 2" clearance between the chimney and the roof. For pitch roof, see table 3 on page 3.

FOR ENCLOSED INSTALLATION AT 2" FROM COMBUSTIBLES

(Woodstove or coal burning appliance only):

Put a ﬁrst chimney length on the Tee. Turn it clockwise to lock it in place (see ﬁgure 4).

Note: the male coupling must be on top.

Slide a Radiation Shield Connector on that ﬁrst chimney section and fasten it using 3 self tapping metal screws.

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 1/2in stainless steel self tapping screw to prevent accidental unlocking.

Figure 19

Attach the clean-out cap to the support's ﬂue extension using the three metal screws provided. Make sure that the screws have pierced

through the ﬂue extension. The cap is in the box with the insulated tee. If an insulated tee cap is used, twist lock the tee cap to the tee (adjustable support DTC-TSA only).

The minimum length of insulated chimney required to pass through the wall will be thickness plus 7". The insulated chimney must extend at least 5" into the room beyond the ﬁnished wall. Insert this chimney length in the side entry of the insulated tee. Turn it clockwise to lock it in place. Seal this joint by wrapping it with the aluminium tape supplied with the tee.Mount the insulated tee on the support so that the chimney length which will go through the wall is perpendicular to the side of the support that will fasten to the wall.

This step will require 2 people: (See ﬁgure 20)

Insert the chimney length of this tee-support assembly into the hole in the wall. Using a level, ensure the tee is vertical, then attach the support to the wall using (8) Nº. 10 x 1 - 1/4" wood screws or 4" spiral nails. NOTE: To provide sufﬁcient strength, the nails must be driven into the wall studs. For concrete walls, the support should be attached using (8) 1/4" x 2" lag bolts.

Slide a telescopic rigid shield over that section and attach it to the radiation shield connector.

Continue installing chimney sections up through the roof opening. Pull the telescopic shield tube up to the roof opening Adjust the length of the shield tube so that it terminates just above the roof opening but under the ﬂashing. Screw the sections of the shield together using 3 self tapping screws per joint.

Step 2. From below push the support into the framed hole. Nail the

support to the framed box using (12) 3" spiral nails (see Figure

21).

Step 3. Put this ﬁrst chimney length in the support. Turn it clockwise to

lock it in place.

NOTE: The male coupling must be on top. Step 4. From below, install a ﬁrestop (DTC-FS) in each ﬂoor through

which the chimney passes (see Figure 22).

Step 5. 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. Continue until the required chimney height is reached.

Step 6. At the attic level, install a ﬁrestop (DTC-FS), from below and an

attic radiation shield (DTC-ISI) from above (see Figure 23).

Step 7. U.S. ONLY: Install the roof radiation shields in the roof joists.

These shields consist of four metal plates. Nail one plate to each side of the joist using (2) 2-1/2’’ nails.

Step 8. Put the roof ﬂashing in place. Seal the joint between the roof

and the ﬂashing with rooﬁng pitch.

For sloping roofs, place the ﬂashing under the upper shingles

and on top of the lower shingles.

Nail the ﬂashing to the roof using rooﬁng nails. Step 9. Place the storm collar over the chimney and the ﬂashing. Tighten

it with the bolt supplied making sure the joint is properly caulked

(see Figure 24).

Fit the rain cap to the top of the chimney. Turn it clockwise to

lock it in place.
