Rigid stainless steel liner is used to mend and improve masonry chimney liners that vent Category solid, liquid or gas-fuel (coal, wood, oil, etc) fired appliances.
Materials and Construction
304 type stainless steel.
2" clearance to masonry chimney.
Available in 5" to 8" diameters.
UL 1777, ULC S635M & ULC S640M.
- Ventinox Rigid lining system can be substituted to the traditional clay tile liner in new masonry chimney construction.
- The liner is intended for use with solid, liquid and gaseous fuel burning appliances at these allowable flue gas temperatures:
|Table 1 |
| ||U.S ||CANADA |
|Maximum continuous ||1000 F |
|1200 F |
|Brief forced firing ||1400 F |
|1700 F |
|Tested to ||2100 F |
|2100 F |
- Size the liner in accordance with the appliance manufacturer's instructions. The liner must not be smaller than the appliance flue outlet.
- 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 (fig. 1).
- 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).
- 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.
- 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.
- The maximum height of liner that can be installed is 60 feet (18 m).
- 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.
- Sharp bends that would crimp and restrict the crosssection of the liner are prohibited.
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.

|Exterior installation ||1"(25 mm) ||1"(25 mm) |
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 specified in NFPA 211 (USA) or the National Building Code (Canada) (See table 2).
