Installation Instructions

PI-EZINS 12/16/14
APPLICATION INFORMATION
Saf-T Vent Model EZ Seal Gas Vent Systems may be used to vent safety certified Category I, II, III, IV and
Certain Direct Vent gas appliances with a flue gas temperature of not more than 550° F (288° C). When used as
a masonry chimney liner, Saf-T Vent EZ Seal can be used to vent condensing oil appliances and category I, II, III,
IV gas fired appliances. The Saf-T Vent EZ Seal system is for use with appliances which produce positive vent
pressures of 9 inches of water column or less. Because these types of appliances may produce vent gases under
positive pressure and/or at or near their dew point, special installation considerations may be required.
Install in accordance with these instructions and those of the appliance manufacturer. Consult the appliance
manufacturer’s instructions for the maximum horizontal length of the vent connector as well as any restriction on
total vent height, proper sizing of the vent, common venting considerations and procedures for connecting the
vent to the appliance.
The installation must conform to applicable National, Regional, State and local codes. Contact the Authority
Having Jurisdiction prior to beginning any work to obtain any required permits.
Pre-Installation Considerations:
Proper planning prior to installation is essential for maintaining proper clearances and for avoiding possible
contact with concealed plumbing or electrical wiring inside walls, floors and ceilings. A continuous straight-line
upward pitch of at least 1/4 inch (2 degrees) rise per foot on horizontal runs must be maintained in order to
properly rid the system of the corrosive condensate. Be sure to plan a sufficient number of supports for the entire
system to maintain the required straight-line pitch and to hold the system in place. Where the vent is enclosed
within a chase, the enclosures should be built to permit future inspection of the system.

Personal Safety
Wear eye protection and heavy gloves throughout the installation. In addition, wear an approved dust and vapor
respirator whenever in contact with building insulation. Proper and safe scaffolding and/or ladders should be
used. Check overhead for antennas, power lines or other obstacles before erecting ladders or scaffolding and
while working with conduit on any roof structure.
Tools Required for Installation
Common building tools including but not limited to a Tape Measure, Pliers, Screw Drivers, Saws and/or Snips,
Drills, Drop Cloth(s); Ladder/Scaffold; Safety and Personal Protective Clothing.
Definitions:
AL 29-4C - A super ferritic stainless steel alloy designed by Allegheny Ludlum for extreme resistance to chloride
ion pitting, crevice corrosion and stress corrosion cracking. Equivalent material made by other manufacturers
may be identified by the UNS designator S44735.
Category I Appliance - An appliance which operates with a non-positive vent static pressure and with a vent gas
temperature that avoids excessive condensate production in the appliance.
Category II Appliance - An appliance which operates with a non-positive vent static pressure and with a vent gas
temperature that may cause excessive condensate production in the appliance.
Category III Appliance - An appliance that operates with a positive vent static pressure and with a vent gas
temperature that avoids excessive condensate production in the appliance.
Category IV Appliance - An appliance that operates with a positive vent static pressure and with a vent gas
temperature that may cause excessive condensate production in the appliance.
Combustible Material - Any material made of or surfaced with wood, compressed paper, plant fibers, or other
materials that are capable of being ignited or burned. Such material shall be considered combustible even
though it is flame proofed, fire-retardant treated, or plastered. (Source: NFPA54/ ANSI Z223.1-2006.).
