Combustion Air Supply & Ventilation; Vent Pipe System; Draft Hood Installation; Roof Jack Installation - Kenmore 153.336340 Owner's Manual

Carbon Monoxide Warning
The vent system must be installed according to all
local and state codes or, in the absence of local and
state codes, the "National Fuel Gas Code", ANSI
Z223.1 (NFPA 54)-current edition. Manufactured home
manufacturers must comply with the "Manufactured
Home Construction and Safety Standard, Title 24 CFR,
Part 3280."
Failure to do so can result in death, explosion, or
carbon monoxide poisoning.
IMPORTANT: Air for combustion and ventilation must not come
from a corrosive atmosphere. Any failure due to corrosive elements
in the atmosphere is excluded from warranty coverage.
The following types of installation (not limited to the following)
wilt require outdoor air for combustion due to chemical exposure
and may reduce but not eliminate the presence of corrosive
chemicals in the air:
• beauty shops
• photo processing tabs
• buildings with indoor pools
• water heaters installed in laundry, hobby, or craft rooms
• water heaters installed near chemical storage areas
Combustion air must be free of acid-forming chemicals such as sulfur,
fluorine, and chlorine. These elements are found in aerosol sprays,
detergents, bleaches, cleaning solvents, air fresheners, paint, and
vamish removers, refrigerants, and many other commercial and
household products. When bumed, vapors from these products
form highly corrosive acid compounds. These products should not
be stored or used near the water heater or air inlet.
Vent Pipe System
This water heater uses a non-direct, single-pipe vent system
to remove exhaust gases created by the burning of fossil
fuels. Air for combustion is taken from the immediate water
heater location or is ducted in from the outside (see "Enclosure
Installation").
This water heater must be properly vented for the removal of
exhaust gases to the outside atmosphere. Correct installation
of the vent pipe system is mandatory for the proper and efficient
operation of this water heater and is an important factor in the
life of the unit.
The vent pipe must be installed according to all local and state
codes or, in the absence of local and state codes, the "National
Fuel Gas Code", ANSI Z223.1 (NFPA 54)-current edition.
Manufactured home manufacturers must conform with "The
Manufactured Home Construction and Safety Standard, Title
24 CFR, Part 3280." The vent pipe installation must not be
obstructed so as to prevent the removal of exhaust gases to the
outside atmosphere.
IMPORTANT: The use of vent dampers is not recommended
by the manufacturer of this water heater. Although some vent
dampers are certified by CSA International, this certification
applies to the vent damper device only and does not mean they
are certified for use on this water heater.
U.L. recognized fuel gas and carbon monoxide (CO) detectors are
recommended in all applications and should be installed using the
manufacturer's instructions and local codes, rules, or regulations.
IMPORTANT: If you tack the necessary skills required to
properly install this venting system, you should not proceed, but
get help from a qualified technician.
Draft Hood Installation
rDRAFT
HOOD
-,I" ,____4__.._ ",
INSTALL THE DRAFT HOOD WITH
THE FOUR SCREWS PROVIDED.
FIGURE 14.
Align the legs of the draft hood with the slots provided. Insert
the legs and secure the draft hood to the water heater's top
with the four screws provided as shown in Figure 14. Do not
alter the draft hood in any way. If you are replacing an existing
water heater, be sure to use the draft hood supplied with this
water heater.
Roof Jack Installation
This water heater must have a property-installed draft hood
and be connected to a listed roof jack that terminates to the
outdoors. The roof jack vent pipe must be secured to the draft
hood with sheet metal screws. (Roof jack not furnished.)
The following roof jack models are certified for use with this
water heater:
1. Field Controls No. 987
2. Ventline 2073
3. White Metal Products 3RJ
Install the roof jack according to its manufacturer's instructions.
