FOR CORRECT INSTALLATION OF VENT SYSTEM, READ ALL
OF THESE INSTRUCTIONS AND REFER TO THE VENT PIPE
MANUFACTURER’S INSTRUCTIONS.
•
FAILURE TO USE THE VENTING SYSTEM DESCRIBED IN THIS
DOCUMENT WILL VOID THE MANUFACTURER’S WARRANTY
AND MAY RESULT IN RAPID DETERIORATION OF THE
VENTING SYSTEM, CREATING A POTENTIAL HEALTH HAZARD.
•
FAULTY VENT INSTALLATION CAN ALLOW TOXIC FUMES TO
BE RELEASED INTO LIVING AREAS. THIS MAY CAUSE
SERIOUS BODILY INJURY OR PROPERTY DAMAGE. IMPROPER
ASSEMBLY MAY ALSO AFFECT VENT PERFORMANCE.
•
INSTALL SEPARATE VENTS FOR FORCED EXHAUST
APPLIANCES AND NATURAL DRAFT APPLIANCES. A COMMON
VENT BETWEEN NATURAL DRAFT AND FORCED EXHAUST
APPLIANCES MAY CAUSE TOXIC GASES TO EXHAUST
THROUGH THE NATURAL DRAFT APPLIANCE RATHER THAN
TO OUTSIDE AIR. BREATHING EXHAUST GASES WILL CAUSE
SERIOUS PERSONAL INJURY OR DEATH.
1.3. GAS VENT CATEGORIES
Innovation and ReCon water heaters are approved for a Category II and Category IV vent
configuration as well as for ducted combustion air installations.
Provisions for combustion and ventilation air in accordance with
Section 5.3, (Air for Combustion and Ventilation) of the National Fuel
Gas Code - ANSI Z223.1, or Sections 7.2, 7.3, or 7.4 of CAN/CSA
B149.1, Installation Codes, or applicable provisions of the local
building codes.
Federal Codes have categorized gas appliances by the vented flue gas pressure and temperature as
follows:
•
Category I
, being a gas appliance that operates with a non-positive vent (or natural drafted
vent) connector with a flue gas pressure and temperature at least 140°F (60°C) above its dew
point.
•
Category II
, being a gas appliance that operates with a non-positive vent (or natural drafted
vent) connector with a flue gas pressure and temperature less than 140°F (60°C) above its dew
point.
•
Category III
, being a gas appliance that operates with a positive vent (fan forced vent)
connector with a flue gas pressure and temperature at least 140°F (60°C) above its dew point.
