Installation and Operating Instructions

Read these instructions and keep them for future reference.
Before installing this liner, consult your local building
authority and obtain a building permit
Install the liner as described in these instructions. Only use parts supplied

by DURAVENT Ltd. Failure to do so will void the certication and the

guarantee of this chimney.

GENERAL NOTES

1. Ventinox Rigid lining system can be substituted to
the traditional clay tile liner in new masonry chimney
construction.

2. The liner is intended for use with solid, liquid and
gaseous fuel burning appliances at these allowable

ue gas temperatures :

U.S CANADA

Maximum continuous 1000 F

Brief forced ring 1400 F

Tested to 2100 F

3. Size the liner in accordance with the appliance
manufacturer's instructions. The liner must not be

smaller than the appliance ue outlet.

4. The chimney shall extend at least 3 ft (915 mm)
above its point of contact with the roof and at least
2 ft (10 mm) higher than any wall, roof or adjacent

building within 10 ft (3 m) of it (g. 1).

5. The clearance between single wall stove pipe and
unprotected combustible material must not be less
than 18" (457 mm) (See National Building Code or
NFPA).

6. A rain cap must be used on top of the liner to
prevent the entrance of debris, rain, birds or small
animals into the liner.

7. Homeowners must be reminded to check the rain
cap for icing during conditions of low ambient
temperatures due to the possibility of blockage
through freezing moisture. The local authority
having jurisdiction should be consulted if a rain cap

is considered in areas of low ambient temperature.

8. Masonry chimney construction:

• The masonry chimney must be built with bricks
and mortar conformed to the Building Code.

The ue opening dimension must always leave

the liner free to expand.

9. The maximum height of liner that can be installed is
60 feet (18 m).

10. Special precaution should be taken in choosing the
correct size of liner system in colder climate region.
Poor draft, excessive condensation and creosote
build-up could occur if the liner system is too big for
the application.

11. Sharp bends that would crimp and restrict the cross­section of the liner are prohibited.

MASONRY CHIMNEY

Before installing the liner into an existing masonry

chimney, the chimney must be thoroughly cleaned
and examined. Check to ensure that the chimney is
structurally sound.

Check for cracked, loose or missing bricks, moisture

or other materials that could inhibit correct installation
of the liner.

For a new masonry chimney liner installation make sure
that the masonry chimney construction and clearances
between the chimney exterior and combustible

materials are as specied in NFPA 211 (USA) or the

National Building Code (Canada) (See table 2).

GENERAL INFORMATION

CREOSOTE

When wood is burned slowly, it produces tar and other organic vapours, which combine with expelled moisture to form

creosote. The creosote vapours condense in the relatively cool chimney ue of a slow burning re. As a result, creosote
residue accumulates on the ue lining. When ignited, this creosote makes an extremely hot re.

Creosote formation in a chimney cannot be eliminated, but it can be minimized by :

1. Keeping the temperature of the gases in the chimney above 300ºF.

2. Making small hot res rather than slow burning, smoldering res.
The chimney liner should be inspected periodically during the heating season to determine if a creosote build-up has occur.

If a signicant layer of creosote has accumulated ((1/8" (3 mm) or more)) it should be removed to reduce the risk of a
chimney re.

CHIMNEY OPERATION AND MAINTENANCE

Keep your chimney and liner clean.

Do not allow more than 1/8" build-up of creosote in your liner. Wood stoves can quickly create large deposits of creosote in

the liner. Some wood stoves can create enough creosote in two weeks to cause a chimney re.

When using a wood stove, we recommend that you :

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

2. The liner should be inspected at least once every 2 months during the heating season to determine if a
creosote or soot build-up has occur. If creosote or soot has accumulated, it should be removed to reduce the

risk of a chimney re.

3. Have your liner cleaned by a qualied chimney sweep. If you want to clean your liner yourself, then use plastic, wood

or stainless steel brushes. Do not use a brush that will scratch the stainless steel interior of the liner.

4. Do not expect chemical chimney cleaners to keep your liner clean. Their use does not negate the necessity of

periodically inspecting and cleaning your liner.

COAL

Some coals contain large quantities of sulphur (up to 7%). When coal is burned, sulphur and coal ashes are deposited in
the liner. This deposit combines with moisture to form a highly corrosive acid (Sulphuric Acid). In order to protect your liner,
we recommend that you burn only low sulphur coals (less than 1% sulphur). Have your liner cleaned within 48 hours of

shutting down your stove at the end of the heating season. Be certain that all the soot is removed. Wipe the liner ue using

a strong solution of baking soda and water. This can be done by wrapping a rag around a chimney cleaning brush, dipping
it in the baking soda-water solution, then passing it through the liner three or four times.

CHIMNEY FIRES

If you are having a chimney re, follow these steps:

1. Close all heater doors and combustion air controls. For replaces, block the replace opening with a non-
combustible material (such as an asbestos or steel sheet).

2. Alert your family to the possible danger.

3. If you require assistance, alert your re department.

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

5. Watch for smouldering or re 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 qualied chimney sweep
or Fire Department inspector. The TUBINOX lining system has been designed to withstand the intense heat of a

chimney re. Nevertheless, chimney res are dangerous and should be avoided.
