VENT PIPING SYSTEM (CONT.)
VENT TERMINAL LOCATIONS
The vent outlet must not terminate:
•
near walkways
• under a covered area or patio
•
into an alley or other publicly accessible areas
•
opposite a window where air currents would
draw the ex-haust into the enclosure.
•
in areas where children or animals could block
the pipe or inhibit the proper operation of the
water heater.
•
in areas where dripping condensate may cause
problems such as above patios, flowerbeds and
planters.
IMPORTANT: Do not use the warm air that
discharges from the vent outlet as a heat source.
Vent termination clearances are as follows:
•
12 inches above roof or grade level and/or twelve inches above
maximum snow level.
•
4 ft. below, 4 ft. horizontally from, or 1 ft. above any door, window or
gravity air inlet to the building.
•
3 feet above any forced air inlet located with 10 feet.
•
2 ft. horizontally from gas or electric meters. Do not install above a
gas meter, regulator, or electric meter.
•
3 ft. from an inside corner formed by two exterior walls
.
VENT TERMINAL INSTALLATION
DANGER
OBSTRUCTIONS OR HOLES IN THE VENT PIPE CAN CAUSE
TOXIC FUMES TO ENTER THE HOME RESULTING IN CARBON
MONOXIDE POISONING OR DEATH
.
THROUGH THE WALL
The vent terminal is a 45 degree elbow. This is shipped with the water heater and
must be used as the vent terminal.
Install as follows:
1. Extend the vent outlet pipe 2 inches beyond the surface of the vertical
outside wall. Caulk the area between the pipe and the outside wall.
2. Glue the vent terminal onto the vent outlet pipe as shown. Make sure that
the vent terminal outlet is facing downward to the ground.
THROUGH THE ROOF
This water heater may be vented vertically through a roof by using a U-bend pipe
fitting as a vent terminal. Install as follows:
1. Extend the vent outlet pipe above the roof so that the outlet of the vent terminal will be at
least 12 inches above the roof or anticipated snow level as shown.
2. Install roof flashing or other approved means to seal the pipe where it exits the roof. Caulk
all gaps and openings to insure a tight seal.
3.
Glue the U-bend vent terminal onto the vent pipe with the outlet of the terminal facing
downward towards the roof.
CAUTION
MOISTURE IN THE FLUE GASES MAY CONDENSE AND FORM ON THE
INTERIOR OF THE GAS VENT PIPE. VENT PIPING INSTALLED IN
UNCONDITIONED SPACES MUST BE INSULATED. IMPROPER LOCATION OR
INSTALLATION CAN CAUSE STRUCTURAL DAMAGE TO THE RESIDENCE.
