CAUTION:
Metal-Fab gas vent relining systems have been designed to properly vent Category I gas-burning appliances only. Appliances
burning solid or liquid fuels or Category II, III, or IV furnaces are not to be connected to this lining system.
This Metal-Fab lining system is intended for use as a masonry chimney liner, factory-built chimney liner, or Type-B gas vent liner.
Metal-Fab liners are intended to be installed in accordance with the standard for chimneys, fireplaces, vents and solid fuel burning
appliances, per NFPA 211.
NOTE: When an existing gas, oil, or wood burning appliance is being replaced by a gas burning appliance, the existing
chimney can be used as a conduit for a flexible aluminum liner. The inside of the existing system must be of sufficient
diameter to allow the liner to pass through and the existing system must have been properly installed (See Manufacturer's
instructions for details).
Although this product may be installed in an unenclosed space between the appliance and the masonry chimney,
factory-built chimney, or Type-B gas vent, it must not pass through any combustible structure such as a wall, ceiling,
floor, attic space, or crawl space. Contact local building or fire officials about restrictions and installations in your area.
Metal Fab gas vent relining systems have been designed to properly vent gas burning appliances. Substituting other
parts not identified within these instructions may pose an unsafe installation. Acceptance of the lining system is void if
the installation instructions are not followed.
Wall penetration assemblies are not to be located directly behind a heating appliance.
The chimney liner must not be sized less than that specified in the appliance manufacturers instructions. Correct sizing
of liner is critical for venting of low temperature flue products in geographical areas experiencing sustained low ambient
temperatures.
Prior to installing a liner system in a masonry chimney, the chimney is to be thoroughly cleaned and inspected. Check
for cracked, loose or missing bricks, mortar or other materials that could inhibit correct liner installation. Repair chimney
as required. Removal of all tar glazed creosote is a must prior to installation of chimney liner. Verify the air space
clearances between the masonry chimney exterior and combustible materials is in accordance with applicable building
code requirements.
Prior to installing linear system in a factory-built chimney or Type-B gas vent, the chimney is to be thoroughly cleaned
and inspected. Check for structural defects that all parts (such as support, radiation shield, firestop, etc.) specified by
the chimney or vent manufacturer. Repair chimney or vent as required. Removal of all tar glazed creosote is a must
prior to installation of chimney liner. Verify that the airspace clearances between chimney or vent exterior casing and
combustible material is in accordance with the installation instructions.
Wear gloves when handling metal parts to avoid personal injury.
