Stainless Steel Chimney Liner
The Heat-Fab Saf-T Liner system is intended for use in conjunction with any residential building,
heating appliance burning gas, liquid or solid fuels, such as a woodstove, fireplace insert, or an oil or
gas fired central heating furnace, vented through
masonry chimneys only. These heating appliances
may not exceed the maximum continuous flue-gas outlet temperatures of 1000
O
F or cause
condensation of corrosive acids on the liner, or create positive pressures in the chimney system.
Saf-T Liner is a high quality U.L. tested and Listed stainless steel lining system designed for relining existing
masonry chimneys. It satisfies code requirements as a substitute for 5/8" fireclay liners and has undergone
extensive testing to make it the leader in the stainless steel chimney lining industry. Heat-Fab recommends that
the installation of Saf-T Liner be performed by an experienced professional who works with chimney and
woodstove related products on a regular basis. Saf-T Wrap is a safe, high quality, easy to install ceramic
insulation jacket for stainless steel lined masonry chimneys. Saf-T Wrap when used in conjunction with Saf-
T Liner will upgrade a chimney to an HT type chimney system. The following instructions are intended as a guide
to assist a qualified professional installer. Check your local building codes and contact local building or fire
officials to obtain any required permits. Warning: Incorporation of parts or materials not manufactured or
supplied by Heat-Fab may not provide a Listed system. Order Heat-Fab’s installation videotape for further
information, available in VHS format.
SAFETY FIRST
The National Fire Protection Association Standards Nos. 54 and
211 require the chimney to extend at least 3 feet above the highest
point where it passes through the roof, and at least 2 feet higher than
any portion of the building within 10 feet (Fig.1).
The Saf-T Liner should not extend more than 6 inches above the
masonry chimney. Any additional flue liner height above the
masonry chimney will create condensation resulting in the buildup
of excessive creosote.
Do not connect more than one solid fuel burning appliance to a single chimney flue and do not connect gas or
liquid fired appliances to chimney flues serving a solid fuel burning appliance.
Wear eye protection and heavy gloves throughout installation. Wear eye protection and dust respirator
whenever in contact with creosote, soot, mortar or insulation. Caution must be used when working on a roof.
Proper and safe scaffolding should be used for a safe installation. All ladders should be secured to the building.
Check overhead for antennas, power lines, or other obstacles before erecting the ladder and installing liner.
CHIMNEY PREPARATION
Lay out ground cloths to protect the inside of the home before sweeping the chimney. Clean and remove all tar
glazed creosote and soot deposited on the internal chimney walls, and smoke chamber of the fireplace, failure
to throughly clean the chimney before installing a new liner system may lead to fire and or smoke damage to
the home. Always use a dust respirator when in contact with soot and creosote.
Inspect the chimney for the following structural weaknesses before it is lined:
• Loose or eroded mortar
• Cracks in the masonry
• Missing bricks
• Internal obstructions that could inhibit installation
Repair all structural weaknesses before proceeding with installation of Saf-T Liner.

CLEARANCE FROM COMBUSTIBLES
Air space clearances between the masonry chimney exterior and
combustible materials should be checked to verify that the chimney is in
accordance with the following clearance specifications (Fig. 2). The
minimum air space clearance between masonry chimneys and combustible
materials shall be at least 1" for a UL Listed Installation.
DETERMINING THE LINER DIAMETER
The Saf-T Liner must be properly sized for your heating appliance. The
diameter of the Saf-T Liner for a single appliance shall not be less than the
diameter of the appliance flue collar or that specified in the appliance
manufacturer’s instructions. Measure the dimension of the chimney opening
at its smallest point (Fig.3). Take the smaller of the two measurements (A&B)
and deduct 2" to arrive at the maximum diameter of Saf-T Liner that may be
installed. Saf-T Liner may be installed in any chimney with an inside diameter
greater than 7"x7" and constructed of 4" thick nominal solid or cored, brick or
masonry. When using Saf-T Liner to vent a fireplace, the cross section
opening of the flue shall not be less than 1/10th of the face area of the fireplace
opening, to insure proper draft (Fig. 4). Custom rectangle or square Saf-T
Liner is available for flues which will not fit the required size round liner.
DETERMINING THE TOTAL LENGTH OF SAF-T LINER
Saf-T Liner is recommended for use in chimneys measuring in height from
8' to 80'.
Non-Fireplace Chimney
Measure the length of the chimney flue to determine the length of liner needed
by utilizing a tape measure. From this length subtract 14" for each tee
required. It is recommended that Saf-T Liner be installed with an accessible
clean-out tee that will facilitate easy cleaning and maintenance of the chimney
system. One tee will be required for the appliance, as well as a tee at the base
of the Saf-T Liner as a clean-out. Determine the distance between these two
tees and then the distance above the appliance tee to the top of the chimney.
The liner assembly will be supported by the tee take-offs and the clean-out tee resting on non-combustible
material.
Hearth/Fireplace Insert Stove
If installing a hearth or fireplace insert stove using an existing fireplace chimney, the length of rigid Saf-T Liner
required will be the distance from the chimney top to the top of the smoke chamber. Listed stainless steel
Chimney Liner components, an engineered Direct Connect Assembly or any other method approved by the local
building authority will be required to pass through the smoke chamber/damper area to the appliance flue collar.
The liner assembly will be supported from the top of the chimney. The installer must verify that there is at least
1 inch clearance to combustibles outside a 3" nominal layer of masonry as well as 1 inch clearance from the
masonry to the connector inside the smoke chamber area for the entire length within the smoke chamber area.
Fireplace
When lining an open fireplace, the total liner length will be the distance from the top of the smoke chamber to
the top of the chimney. This liner assembly will be supported from the top of the chimney. The liner may also
be extended to the damper area if the smoke chamber area is in poor condition. The installer must verify that
there is at least 1 inch clearance to combustibles outside a 3" nominal layer of masonry to insure safe operation
of the fireplace.
