Metal Fab TEMP GUAR 14TG User manual

*Combustible material is dened as material made of, or surfaced with, wood, compressed paper, plant bers,
plastic, or other material that will ignite and burn, whether ame proofed or not, or whether plastered or unplastered.
The Metal-Fab Temp/Guard Chimney is intended for use on any residential and building heating appliance burning gas, liquid or solid
fuels such as replace stoves, furnaces, ranges, room heaters, or as dened in columns I and II, Table 2-2.1, NFPA 211. Contact Local
Building or Fire Ofcials about restrictions and Installation Inspection in your area.
WARNING: Metal-Fab Temp/Guard Chimney is not designed for use on products that operate at continuous temperatures in
excess of 1,000°F.

A MAJOR CAUSE OF CHIMNEY RELATED FIRES IS FAILURE TO
MAINTAIN REQUIRED CLEARANCES (AIR SPACES) TO COMBUSTIBLE
MATERIAL.* MINIMUM CLEARANCE FOR 14”, 16” & 18” TEMP/GUARD IS
TWO (2) INCHES. IT IS OF UTMOST IMPORTANCE THAT THIS CHIMNEY
IS INSTALLED ONLY IN ACCORDANCE WITH THESE INSTRUCTIONS.
IMPORTANT: FOR OIL OR COAL BURNING APPLIANCES, OUTSIDE THE ENVELOPE OF THE BUILDING, USE ONLY PIPE WITH
STAINLESS STEEL CASING, ALSO USE FLASHING OR STORM COLLARS CONSTRUCTED OF STAINLESS STEEL OR ALUMINUM.
OPERATIONAL PRECAUTIONS
• Maintain 2” minimum clearance to combustibles for 14”, 16” & 18” diameters. (Refer to WARNING above). Use only U.L. Listed
products and INSTALL ONLY IN ACCORDANCE WITH MANUFACTURER’S INSTRUCTIONS.
• Formation of Creosote and Soot and the need for removal.
When wood is burned slowly, it produces tar and other organic vapors, which combine with expelled moisture to create
creosote. The creosote vapors condense in the relatively cool chimney ue of the slow burning re. As a result, creosote
residue accumulates on the ue lining. When ignited, this creosote makes an extremely hot re. The chimney should be
inspected at least once every two (2) months during the heating season to determine if a creosote or soot buildup has
occurred. If creosote or soot has accumulated, it should be removed to reduce the risk of chimney re.
• Do not use replace for food grill. Grease from foods can collect in chimney causing replace to become a potential re
hazard.
• On airtight stoves, open dampers and let equipment burn hot for 15 to 20 minutes. This should be done every time fuel is added.
This lessens the chance of creosote buildup.
• Some chemical chimney cleaners can be harmful to the chimney. These cause accelerated oxidation or corrosion. If chemical
cleaners are used, they must be non-corrosive in nature. If brush is used, it must be of proper size with plastic bristles.
• The 14TG, 16TG and 18TG chimney system is to be installed through a chase and not intended to pass through attic areas that
require insulation shields.
• Except for installation in one- and two-family dwellings, a factory-built chimney that extends through any zone above that on
which the connected appliance is located is to be provided with an enclosure having a re resistance rating equal to or greater
than that of the oor or roof assemblies through which it passes.
• Enclose exterior mounted chimneys below the roof line in geographical areas experiencing sustained low ambient temperatures
to help reduce or limit condensation, creosote and poor draft.

CHIMNEY ASSEMBLY
The 14TG, 16TG and 18TG chimney system is designed for
quick and easy installation. The ue and casing assemble at
each joint using a male to female slip t. Each joint is secured
together with four (4) each sheet metal screws at the casing
(See FIG. 1).
MASONARY FIREPLACE CHIMNEY,
AND CHIMNEY EXTENSION
An anchor plate (TGAP) is used to attach Metal-Fab 1700°F
Chimney to a masonry replace or chimney. Maximum
support height of 50 ft.
1. Where the transition is to be made, apply a bed of mortar
approximately 3/4 inches deep and approximately one
(1) inch larger than the anchor plate. (See TG Chimney
Catalog for anchor plate dimensions).
2. Insert four (4) 1/4-20 x 2” anchor bolts, head down into the
mortar bed. J-style anchor bolts are preferred. An alternate
method would be to allow the mortar bed to cure. Then, drill
four (4) holes, matching the holes in the anchor plate and
insert four (4) each 1/4-20 metal anchors. The anchor plate
would then be attached by four (4) each 1/4-20 bolts.
3. Before the mortar sets, place the anchor plate over the bolts
and press down into the mortar. Loosely secure using a
washer and nut on each bolt.
4. Use a level to check the installation, assuring that the TG
chimney connection (TGAP) is level.
5. When the mortar has set up, tighten the nuts onto the bolts.
Proceed to stack Metal-Fab chimney pipe (TG) on the
anchor plate (See FIG. 2 and TABLE 1 for framing
dimensions).
6. See “Flashing Instructions” and “Termination” sections.
NOTE: Existing masonry ues may be extended with TG pipe
by using an anchor plate, following steps 1 through 6 above,
provided that (See FIG. 3):
a) The existing masonry chimney is structurally sound,
and;
b) The ue extension is properly sized so that the
appliance attached to the ue drafts properly.
NOTE: The TG ue size for a height less than 15 feet should be
at least 1/8 the area of the replace opening. The TG ue size
for a height over 15 feet should be at least 1/10 the area of the
replace opening. (For sizing of TG ue, See Metal-Fab literature
L1372.)

ELBOW INSTALLATION
1. 15° (TGA15) and 30° (TGA30) elbows are provided to allow
chimneys to avoid framing member or roof peaks. A
maximum of 30° from the vertical is allowed, and a total of
four elbows (two pair) for each chimney installation Maintain
2” clearance to combustibles for 14”, 16” and 18” diameters.
2. Attach the elbow to the chimney pipe or other support part.
Using the offset chart, add chimney sections between
elbows. A support band or plumbers strap is required every
4 foot interval between elbows to support the load as
shown in FIG. 4. Attach the upper elbow to bring chimney
back to vertical. See Table 2 and FIG. 5 for offset
combinations.
FLASHING INSTALLATION
1. Continue the TG chimney to the roof. Cut the roof opening,
centered over the chimney. A 2” airspace around
the chimney is required as it penetrates the roof
(See FIG. 6 and TABLE 1 for construction and framing
dimensions).
2. Install the next TG chimney section through the roof and
install the ashing (TGF) around the chimney and centered
over the roof penetration opening.
NOTE: If your roof is already shingled, be sure to slide the upper
edge under the shingles to prevent leakage.
3. Install a radiation shield (TGRSH) over the chimney
section and center the radiation shield within the joist area.
Bend straps of radiation shield over the top edge of ashing
to position in place. Apply a bead of caulk around the pipe at
the top edge of the ashing screen. Wrap the Storm Collar
around the pipe and imbed the edge of caulk to prevent
leakage around pipe. Bend the ashing strap around the tab
to tighten around the chimney (See FIG. 6).
4. Continue to install pipe sections until proper termination
height is reached. See termination section.

TERMINATION
Major building codes specify a minimum chimney height above
the roof top. These specications are summarized in what is
known as the “Ten Foot Rule”. This rule states:
If the horizontal distance from the side of the chimney to the peak
of the roof is 10 feet or less, the top of the chimney must be at
least 2 feet above the peak of the roof, but never less than 3 feet
in overall height above the highest point where it passes through
the roof (FIG. 7).
If the horizontal distance from the side of the chimney to the peak
of the roof is more than 10 feet, a chimney height reference point
is established on the surface of the roof a distance of 10 feet
from the side of the chimney in a horizontal plane. The top of the
chimney must be at least 2 feet above this reference point, but
never less than 3 feet in height above the highest point where it
passes through the roof (FIG. 8)

These chimney heights are necessary in the interest of safety
and do not ensure smoke free operation. Trees, buildings,
adjoining roof lines, adverse wind conditions, etc., may create
need for a taller chimney should smoking occur.
Additional support is required above the roof if the chimney
height exceeds four (4) feet.
