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 12" above the ground (or above

snow accumulation level), then the installation can be modified as

shown below.
