INSTALLATION INSTRUCTIONS
The Heat-Fab Saf-T Vent
TM
is a masonry chimney lining and relining system intended
for use with residential appliances burning liquefied petroleum (LP), natural gas,
home heating oil, and solid (wood or coal) fuels. Saf-T Vent is a high-quality,
extremely durable lining system constructed of a special alloy of stainless steel high
in both chromium and molybdenum. This alloy, plus Saf-T Vent's smooth-wall
design, give it a unique combination of corrosion resistance, high temperature
tolerance and desirable flow characteristics not found in any other chimney lining
system.
As with any venting system, its installation must be properly planned and executed in
order to ensure satisfactory results. Incorporation or substitution of parts or materials
not manufactured or supplied by Heat-Fab, or failure to follow these instructions, may
not provide a UL Listed system, and may result in appliance malfunction, fire or
endanger the health and safety of people.
Heat-Fab recommends that the installation be performed by an experienced
professional who works with venting systems for residential appliances on a regular
basis. These instructions are intended as a guide to assist a professional installer. The
installation must conform to the requirements of the appliance manufacturers'
instructions, applicable
National Fire Protection Association (NFPA)
standards,
and local codes. Check your local codes and contact local building or fire officials to
obtain any required permits.
IMPORTANT:
THE SAF-T VENT SYSTEM MAY BE INSTALLED IN
SEVERAL DIFFERENT WAYS, USING DIFFERENT PARTS, ACCORDING TO
THE TYPE OF APPLIANCE(S) TO BE CONNECTED. TO ENSURE PROPER
INSTALLATION, FOLLOW THESE MAIN INSTRUCTIONS
AND
THE
SUPPLEMENTAL INSTRUCTIONS INDICATED BELOW.
For Solid Fuel or Oil Appliances:
The liner
must
be insulated with
Saf-T Wrap
Insulation
.
Follow these
Main Instructions
and the
Supplemental General
Residential Instructions
(PI-WRAP) packed with the Saf-T Wrap Insulation.
Category I gas appliances may also be installed per these instructions if desired.

Normal operation of a gas appliance does not result in deposits of combustible soot
or creosote in the venting system. However, a poorly adjusted or malfunctioning
appliance can deposit soot, and leaves or other debris can enter the flue. Just as with
all chimneys and vents the Saf-T Vent should be inspected
annually
for the presence
of deposits or debris and cleaned if necessary. This should be done by a Certified
Chimney Sweep
®
or other qualified person.
To inspect the vent, pry up the locking tabs holding the rain cap to the top of the liner
and remove the cap. Replace the cap by inserting the locking tabs back under the ring
and bending them back into position. The system can also be inspected and cleaned
by removing the connector pipe from the liner tee or elbow.
