vertical flue gas conduit
,
consisting of Saf-T Vent liner sections;
termination assembly
, consisting of top
flashing, rain cap, slip section and storm collar; and a
vent or chimney connector
,
which may be sections of Saf-T Vent flue gas conduit or other approved material.
Other parts may be needed for the specific installation and appliance type -- consult
the appropriate supplemental instructions. Read the instructions thoroughly, plan the
installation, and make sure all necessary parts are on hand before commencing
installation.
Do not substitute any parts not manufactured or supplied by
Heat-Fab, Inc.
A. Open The Chimney
Note:
Wear eye protection and respirator.
An opening must be made in the chimney in the room in which the appliance is located.
If the chimney already has a thimble hole, it will probably require expansion to
facilitate installation of the base assembly.
Locate the hole for the appliance breeching considering available headroom and
clearance to combustibles. (Consult the appliance manufacturer's instructions and
Tables 6-5.1.1 and 6-5.1.2 of
NFPA 211 (1996)
to determine clearance needed for the
Supplemental Category I Instructions
These instructions apply when the Saf-T Vent system will be used only to vent one
or more Category I gas appliance(s). These Instructions are intended as a guide to
assist the professional installer. The installation must conform to the requirements of
the appliance manufacturer's instructions,
The National Fuel Gas Code (NFPA 54)
,
and local codes. Check your local codes and contact local building and/or fire officials
to obtain any required permits.
By following these instructions, Saf-T Vent may be used to vent Category I gas
burning furnaces, boilers, hot water heaters, space heaters and decorative appliances
with a maximum continuous flue gas outlet temperature not exceeding 480° F. The
appliance(s) must be tested by the
American Gas Association
(
AGA
),
Underwriters
Laboratories
(
UL
), or other recognized testing agency, and Listed for use with a Type
B venting system. Although most conventional Category I appliances include a draft
hood, certain newer mid-efficiency Category I appliances are fan assisted, without a
draft hood. They may be vented per these instructions so long as they are
Listed
for
use with Type B vents.
Consult the appliance manufacturer's instructions,
NFPA 54
, Heat-Fab's
Saf-T Vent
Planning & Preparation Manual
and local codes to determine the proper size liner
for the installation, and for information on common venting of more than one
appliance. The liner size must not be smaller than allowed by the appliance
manufacturer's instructions, regardless of flue collar size.
When installed according to these instructions, Saf-T Vent may
not
be used to vent
the following types of appliances:
Gas appliances Listed for use with Type BW Vent;
Category II, III or IV gas appliances,Unlisted gas appliances, oil fired appliances,
multi fuel appliances, solid fuel appliances or appliances that must be vented by a
chimney.
The Saf-T Vent system converts the chimney flue to a dedicated gas vent
designed to optimize the venting conditions for Category I gas appliances.
Chimney Inspection and Preparation
Saf-T Vent is intended for installation in new or existing masonry chimneys which
comply with the requirements of
NFPA 211, Chimneys, Fireplaces, Vents and Solid
Fuel Burning Appliances
.
It is the responsibility of the installer to inspect and
prepare the chimney prior to installation. Consult and follow the
Main Instructions
in this document on inspection and preparation of the chimney.
When intended for use only with Category I gas appliances, the Saf-T Vent system
may be installed in chimneys which have combustible material in contact with the
