LOCATION REQUIREMENTS AND CONSIDERATIONS
WARNING
IT IS NOT DESIRABLE TO INSTALL A GAS FIRED WATER HEATER IN A
RESIDENTIAL GARAGE. IF INSTALLATION IN A RESIDENTIAL GARAGE IS
YOUR ONLY OPTION, THIS WATER HEATER MUST BE INSTALLED SUCH
THAT THE PILOT FLAME AND MAIN BURNER FLAME ARE NO LESS THAN
18 INCHES ABOVE THE FLOOR (SEE FIGURE 2 BELOW). THIS IS TO
REDUCE BUT NOT ELIMINATE THE RISK OF IGNITING FLAMMABLE
VAPORS WHICH MAY BE PRESENT IN A GARAGE. THE WATER HEATER
MUST BE LOCATED OR PROTECTED TO AVOID PHYSICAL DAMAGE
BY VEHICLES OR FLOODING. FAILURE TO FOLLOW THESE
WARNINGS CAN CAUSE A FIRE OR EXPLOSION, RESULTING IN
PROPERTY DAMAGE, PERSONAL INJURY OR DEATH.
SITE LOCATION
1. Select a location near the center of the water piping system. It must
be installed indoors and in a vertical position on a level surface. DO
NOT install in bathrooms, bedrooms or any occupied room normally
kept closed.
2. Locate the water heater as close to the chimney or gas vent as is
practical. Consider the vent system piping and combustion air supply
requirements when selecting the water heater location. The venting
system must be able to run from the water heater to the termination
with a minimal length and elbows. THE VENT PIPE CANNOT
EXCEED THE MAXIMUM ALLOWABLE LENGTH OF 40 FEET WITH
3 LONG RADIUS ELLS.
3. Locate the water heater near the existing gas piping. If installing a new
gas line, locate the water heater to minimize the pipe length and
elbows.
IMPORTANT
4. The water heater should be located in an area where leakage of the
tank or connections will not result in damage to the area adjacent to
the water heater or to lower floors of the structure. It is recommended
that a suitable drain pan be installed under the water heater as shown
above. This pan is to protect the property from damage which may
occur from normal condensate formation on the tank jacket or leaks in
the tank and pipe connections. The pan must limit the water level to a
maximum depth of 1 3/4 inches and be two inches wider than the
heater and piped to an adequate drain. Locate the water heater near a
suitable inside drain. Outside drains are subject to freezing
temperatures. The piping should be at least 3/4” ID and pitched for
proper drainage. This pan must not restrict combustion air flow.
UNDER NO CIRCUMSTANCES IS THE MANUFACTURER TO BE
HELD LIABLE FOR ANY WATER DAMAGE IN CONNECTION WITH
THIS WATER HEATER.
6
5. The water heater should be located in an area not subject to freezing
temperatures. Water heaters located in unconditioned areas (i.e. attics,
basements, etc.) may require the insulation of the water piping and drain
piping to protect against freezing. The drain and controls must be easily
accessible for operation and service.
Maintain proper clearances as specified.
6. Do not locate the water heater near an air-
moving device. The operation of air-moving
devices such as exhaust fans, ventilation
systems, clothes dryers, fireplaces, etc.,
can affect the proper operation of the
water heater. Special attention must be
given to conditions these devices may
create to avoid unsatisfactory operation
of the equipment.
CLEARANCE/ACCESSIBILITY
Minimum clearances from combustible materials are stated on the data plate
adjacent to the thermostat of the water heater. REFER TO THE DATA
PLATE OF THE WATER HEATER FOR THE CORRECT CLEARANCES
FROM COMBUSTIBLE CONSTRUCTION MATERIALS. Figure 3 may be
used as a reference guide to locate the specific clearance locations. A
minimum of 24 inches of front clearance should be provided for inspection and
service.
WARNING
THE WATER HEATER IS CERTIFIED FOR INSTALLATION ON A
COMBUSTIBLE FLOOR. HOWEVER, WHEN THIS WATER HEATER IS
INSTALLED OVER CARPETING, THE CARPETING MUST BE PROTECTED
BY A METAL OR WOOD PANEL BENEATH THE WATER HEATER AND
EXTENDING BEYOND THE FULL WIDTH AND DEPTH OF THE WATER
HEATER BY AT LEAST THREE INCHES IN ANY DIRECTION. IF THE
WATER HEATER IS INSTALLED IN A CARPETED ALCOVE OR CLOSET,
THE ENTIRE FLOOR MUST BE COVERED BY THE PANEL. FAILURE TO
FOLLOW THESE INSTRUCTIONS MAY RESULT IN A FIRE HAZARD.
VENTILATION AND COMBUSTION AIR SUPPLY
GENERAL INFORMATION
WARNING
THIS WATER HEATER AND ANY OTHER FUEL BURNING APPLIANCE
MUST BE PROVIDED WITH ENOUGH FRESH AIR FOR PROPER
VENTILATION OF THE FLUE GASES. MOST HOMES WILL REQUIRE
THAT OUTSIDE AIR BE SUPPLIED INTO THE WATER HEATER AREA.
FAILURE TO DO SO CAN RESULT IN EXPLOSION, FIRE, PROPERTY
DAMAGE, CARBON MONOXIDE POISONING, PERSONAL INJURY OR
DEATH.
Adequate facilities for providing air for combustion and ventilation must be
provided in accordance with the “National Fuel Gas Code”, ANSI Z223.1Latest Edition, NFPA 54 or the applicable provisions of the local building
codes.
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 (but not limited to the following) will
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 labs
• Commercial buildings
• 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 varnish
removers, refrigerants, and many other commercial and household
products. When burned, vapors from these products form highly corrosive
acid compounds. These products should not be stored near the water
heater or air inlet.
Combustion and ventilation air requirements are de-termined by the location
of the water heater. The water heater may be located in either an open
(unconfined) area or in a confined area or small enclosure such as a closet
or small room. Confined spaces are areas with less than 50 cubic feet
for each 1,000 BTUH of the total input for all gas-using appliances.
WATER HEATER LOCATION - UNCONFINED SPACE
A water heater in an unconfined space uses indoor air for combustion and
requires at least 50 cubic feet for each 1,000 BTUH of the total input
for all gas appliances. The table below shows a few examples of the
minimum square feet required for various BTUH inputs.
BTUH
INPUT
30,000 188 9 X 21
45,000 281 14 X 20
60,000 375 15 X 25

105,000 657 20 X 33
120,000 750 25 X 30
135,000 844 28 X 30
Areas which are being used for storage or contain large space consuming
items may not be suitable for water heater installation. The area must be
open and be able to provide the proper air requirements to the water
heater.
MIN. SQ. FEET
WITH 8’ CEILING
TYPICAL ROOM SIZE
WITH 8’ CEILING
IMPORTANT: Water heaters installed in open spaces in buildings with
unusually tight construction may still require outdoor air to function
properly. In this situation, outside air openings should be sized the same as
for a confined space.
MODERN CONSTRUCTION USUALLY REQUIRES SUPPLYING OUTSIDE AIR
INTO THE WATER HEATER AREA.
CONSULT THE LOCAL CODES OF YOUR AREA FOR SPECIFIC
VENTILATION AND COMBUSTION AIR REQUIREMENTS.
For the correct and safe operation of this water heater, ample air must be
supplied for the combustion, ventilation and dilution of flue gases. Small
enclosures and confined areas must have two permanent openings so
that sufficient fresh air can be drawn from outside of the enclosure. One
opening shall be within 12 inches of the top and one within 12 inches
of the bottom of the enclosure as shown in Figure 4 below.
The size of each opening (free area) is determined by the total Btuh input of
all gas utilization equipment (i.e. water heaters, furnaces, clothes dryers,
etc.) and the method by which the air is provided. The Btuh input can be
found on the water heater data plate. Additional air can be provided by two
methods:
1. All air from inside the building.
2. All air from outdoors.
ALL AIR FROM INSIDE THE BUILDING
When additional air is to be provided to the confined area from additional
room(s) within the building, the total volume of the room(s) must be of
sufficient size to properly provide the necessary amount of fresh air to the
water heater and other gas utilization equipment in the area. If you are
unsure that the structure meets this requirement, contact your local gas
utility company or other qualified agency for a safety inspection.
Each of the two openings shall have a minimum free area of 1 square inch
per 1,000 Btuh of the total input rating of all gas utilization equipment in
the confined area, but not less than 100 square inches (Figure 5).
CAUTION
AIR CANNOT BE TAKEN FROM AREAS THAT CONTAIN NEGATIVE
PRESSURE PRODUCING DEVICES SUCH AS FIREPLACES, EXHAUST
FANS, AND AIR CIRCULATION SYSTEMS.
7
VENTILATION AND COMBUSTION AIR SUPPLY (CONT.)
ALL AIR FROM OUTDOORS
Outdoor fresh air can be provided to a confined area either directly or by
the use of vertical and horizontal ducts. The fresh air can be taken from the
outdoors or from crawl or attic spaces that freely communicate with the
outdoors. Attic or crawl spaces cannot be closed and must be properly
ventilated to the outside.
Ductwork must be of the same cross-sectional area as the free area of the
opening to which they connect. The minimum dimension of rectangular air
ducts cannot be less than 3 inches.
The size of each of the two openings is determined by the method in which
the air is to be provided. Refer to Table 1 to calculate the minimum free
area for each opening. Figures 6, 7, and 8 are typical examples of each
method.

Example: A water heater with an input rate of 50,000 Btuh using horizontal
ducts would require each opening to have a minimum free area of 25 square
inches.
Minimum Free Area = 50,000 Btuh x 1 sq. in. / 2000 Btuh = 25 Sq Inches
* These openings may communicate directly with the outdoors through a

POWER VENTILATION.
LOUVERS AND GRILLES
In calculating free area for ventilation and combustion air supply openings,
consideration must be given to the blocking affect of protection louvers,
grilles, and screens. These devices can reduce air flow which in turn may
require larger openings to achieve the required minimum free area. Screens
must not be smaller than 1/4 inch mesh. If the free area through a
particular design of louver or grille is known, it should be used in
calculating the specified free area of the opening. If the design and free
area are not known, it can be assumed that most wood louvers will allow
20 - 25% of free area while metal louvers and grilles will allow 60 - 75% of
free area. Louvers and grilles must be locked open or interconnected with
the equipment so that they are opened automatically during equipment
operation.
Keep louvers and grilles clean and free of debris or other obstructions.

VENT PIPING SYSTEM
GENERAL INFORMATION
DANGER
PROPER VENT PIPE INSTALLATION IS CRITICAL TO THE SAFE
OPERATION OF THIS WATER HEATER. FAILURE TO PROPERLY VENT
THIS WATER HEATER CAN CAUSE AN EXPLOSION, FIRE OR CARBON
MONOXIDE POISONING WHICH CAN RESULT IN PROPERTY DAMAGE,
PERSONAL INJURY, OR DEATH.
This water heater has been certified by CSA International for use with the
specified plastic pipe material.
This vent pipe system must be installed in accordance with the “National Fuel
and Gas Code”, NFPA 54, ANSI Z223.1 - Latest Edition.
The National Fuel and Gas Code allows the use of plastic pipe for venting if it is
accepted by the local code or the authority having jurisdiction.
Some local jurisdictions may be opposed to plastic vent pipe. Check with your
local code official before installing this system.
Use only 3 inch Schedule 40 PVC, ABS-DWP, or CPVC plastic pipe and fittings
for this vent pipe system. All fittings must be Long Sweep. DO NOT USE SHORT
RADIUS OR MEDIUM SWEEP FITTINGS. THE USE OF SHORT RADIUS
FITTINGS WILL CAUSE THIS WATER HEATER TO MALFUNCTION OR
NUISANCE TRIP ON THE PRESSURE SWITCH CAUSING THE BURNER TO
NOT OPERATE PROPERLY.
Pipe and fittings are available from your water heater dealer or through most
plumbing supply houses.
BLOWER OUTLET ADAPTER
The blower outlet adapter must be secured to the outlet of the power vent
blower opening using silicone
adhesive sealant and sheet metal
screws as shown in Figure 9.
1. Apply an even 1/8 inch bead of
silicone adhesive sealant
around the inside of the
adapter’s square opening.
Locate this bead 1/4 inch from
the top of the opening.
1. Slide the adapter approximately
1/2 inch onto the blower
opening and secure with two
sheet metal screws.
IMPORTANT: This connection must
be properly sealed to prevent the leakage of the products of combustion into the
living area. Excess silicone adhesive inside the adapter can cause enough
restriction in the vent pipe to cause intermittent burner operation.
• Vent diameter must not be reduced.
• Support all fittings and pipe runs with proper pipe hold-down hardware at
least every three feet.
• Do not use damaged pipe or fittings.
• All joints must be properly cemented.
• Vent piping installed in unconditioned spaces must be properly insulated
• Make sure the inside of the pipe is clean and free of cuttings and loose dirt.
• Size and cut all piping before cementing. Make clean, square cuts.
• Do not connect this venting system with an existing vent or chimney.
• Do not common vent with the vent pipe of any other water heater or
appliance.
• Do not run plastic vent pipe through a fire break wall.
• Do not screw, nail, rivet or make any holes in the vent pipe or fittings.
• Do not turn on the water heater until the adhesive has completely cured.
DANGER
CONNECTION OF THE VENT PIPE TO THE OUTLET OF THE VENT
ASSEMBLY BLOWER MUST BE PROPERLY SEALED TO PREVENT
LEAKAGE OF THE PRODUCTS OF COMBUSTION INTO THE LIVING SPACE.
IMPORTANT: Fittings such as elbows and couplings must not be attached
directly to the blower outlet. A short length of vent pipe (2 inches minimum)
must be used to connect an elbow or coupling to the blower outlet as shown
in Figure 10.
Use silicone adhesive sealant to secure the vent pipe to the blower outlet. Use
a good grade of pipe cement to secure the vent pipe and fittings to each
other.
For PVC, CPVC, and ABS pipe:
1. Cut the pipe ends square, remove the ragged edges and burrs.
2. Chamfer the pipe end, apply a primer to the fitting and pipe.
3. Apply an even coat of a good grade of pipe cement inside the fitting.
Apply a liberal amount of cement to the outside of the pipe to socket
depth.
4. Assemble the parts quickly while the cement is still wet. Twist the pipe 1/4
turn during insertion and hold together for 30 seconds.
5. Wipe off the excess cement and do not handle for 15 minutes. Cure time
will vary according to temperature, humidity, and fit.
VENT PIPE INSTALLATION
When installing this vent pipe system, please note the following:
• Use only Schedule 40 PVC, CPVC, or ABS-DWV plastic pipe and fittings.
• Maximum vent pipe length is 40 feet with three 90 degree long sweep
elbows.
• The minimum clearance from plastic vent pipe to combustible materials is 0
(zero) inches.
• Venting should be as direct as possible with a minimum pipe length and
fittings.
