VENTING
AWARNIN
Breathing Hazard - Carbon Monoxide Gas
Install vent system in accordance with
codes.
Do not operate water heater if flood
damaged.
High altitude orifice must be installed for
operation above7,700 feet (2,347 m).
Do not operate if soot buildup.
Do not obstruct water heater air Intake
with insulating jacket.
Do not place chemical vapor emitting
products near water heater.
Gas and carbon monoxide detectors
are available.
Never operate the heater unless it is
vented to the outdoors and has adequate
air supply to avoid risks of improper
operation, fire, explosion, or asphyxiation.
Make sure the flue baffle and flue restrictor
ring are properly aligned and Insetted on
top of the flue. This ran be checked
through the dilution air inlet of the blower
assembly. Forwewing, the Air Intake screen
of the blower assembly will have to be
removed. Replace after the check is made.
Breathing carbon monoxide can cause brain damage or death.
Always read and understand instruction manual
The vent system must terminate so that proper clearances are
maintained as cited in local codes or the current edition of the National
.Euel..Gas..Code. ANSI Z223.1/NFPA54, 7.3.4e and 7.8a.b, as follows:
1. The exit terminals of a mechanical vent system shaii be not iess
than 7 feet (2.13 m) above grade when located adjacent to public
walkways, see Figure 23.
2. A venting system shall terminate at least 3 feet (91 cm) above any
forced air inlet located within 10 feet (3.1 m), see Figure 23.
3. The venting system shall terminate at least 4 feet (1.2 m) below, 4
feet (1.2 m) horizontally from or, 12 in. (30 cm) above any door,
window or gravity air inlet into any building.
The manufacturer also recommends that the vent termination should
not be installed closer than 3 feet (91 cm) from an inside corner of an
L shaped structure and not be less than 12 in. (30 cm) above grade.
The vent shall terminate a minimum of 12" (30.5 cm) above expected
snowfall level to prevent blockage ofventtermination, see Figure 23.
4. In cold climates, if is recommended that vent termination not be mounted
directiy above or with in 3 feet (91 cm) horizontally from an oil tank vent or
gas meter to avoid potential freeze-up from condensation, see Figure 23.
Plan the vent system layout so that proper clearances are maintained
from plumbing and wiring.
Vent pipes serving power vented appliances are classified by building
codes as “vent connectors”. Required clearances from combustible
materials must be provided in accordance with information in this manual
under FACTS TO CONSIDER ABOUT THE LOCATION and VENT
TERMINAL INSTALLATIONS, and with the National Fuel Gas Code and
local codes.
VENT TERMINAL INSTALLATION___________________
1. After the point of termination has been determined, use the cover
plate as a template to mark the hole for the vent pipe to insert
through the wall. BEWARE OF CONCEALED WIRING AND PIPING
INSIDE OF WALL.
2. If the Vent Terminal is being installed on the outside of a finished
wall, it may be easier to mark both the inside and outside wall.
Align the holes by drilling a hole through the center of the template
from the inside through to the outside. The template can now be
positioned on the outside wall using the drilled hole as a centering
point for the template.
3. A) MASONRY SIDE WALLS
Chisel an opening approximately one half inch larger than the
marked circle.
B) WOODEN SIDE WALLS
Drill a pilot hole approximately one quarter inch outside of the
marked circle. This pilot hole is used as a starting point for a
saws-all or sabre saw blade. Cut around the marked circle staying
approximately one quarter inch outside of the line. (This will allow
the vent pipe to easily slide through the opening. The resulting
gap will be covered up by the vent terminal cover plates.) Repeat
this step on inside wail if necessary.
4. When the vent piping cannot pass through an outside wall at a
height greater than or equal to 1 2" above the ground (or above
snow accumulation level), then the installation can be modified as
shown below.
