General Information continued-
A sacrificial anode is used to extend tank life. The removal of this anode, for
any reason, will nullify the warranty. In areas where water is unusually active,
an odor may occur at the hot water faucet due to a reaction between the
sacrificial anode and the impurities in the water. If this should happen, an
alternative anode may be purchased from the supplier that installed this water
heater. This will minimize the odor while protecting the tank. Additionally, the
water heater should be flushed with appropriate dissolvers to eliminate any
bacteria.
INSTALLATION
Locating The Water Heater
WARNING
Water heaters are heat producing appliances. To avoid damage or injury, do
not store materials against the water heater or vent-air intake system. Use
proper care to avoid unnecessary contact (especially by children) with the
water heater and vent-air intake components. UNDER NO CIRCUMSTANCES
SHALL FLAMMABLE MATERIALS, SUCH AS GASOLINE OR PAINT
THINNER BE USED OR STORED IN THE VICINITY OF THIS WATER
HEATER, VENT-AIR INTAKE SYSTEM OR IN ANY LOCATION FROM
WHICH FUMES COULD REACH THE WATER HEATER OR VENT-AIR
INTAKE SYSTEM.
This water heater MUST be installed indoors out of the wind and weather.
DO NOT install the water heater in any location where gasoline or
flammable vapors are likely to be present.
CAUTION
The National Fuel Gas Code (ANSI Z233.1-or latest edition) and CAN/CGA
(B149.1-or latest edition), expressly prohibits the installation of a water
heater in a garage, unless the unit is installed so that the burner and
ignition devices are at least eighteen (18) inches (46 cm) above floor level
and protected to avoid damage by a moving vehicle.
The location of this water heater is of the utmost importance. Before installing
this water heater, read the installation section of these instructions. After
reading these installation and operating instructions, select a location for the
water heater where the floor is level and is easily accessible to gas and water
supply lines. DO NOT locate the water heater where water lines could be
subjected to freezing temperatures. Make sure the cold water pipes are
not located directly above the gas control so that condensate during
humid weather does not drip on the controls.

Installation (Locating The Water Heater) continued-
Water heater corrosion and component failure can be caused by the heating
and breakdown of airborne chemical vapors. Examples of some typical
compounds that are potentially corrosive are: spray can propellants, cleaning
solvents, refrigerator and air conditioning refrigerants, swimming pool
chemicals, calcium and sodium chloride, waxes and process chemicals. These
materials are corrosive at very low concentration levels with little or no odor to
reveal their presence. NOTE: DAMAGE TO THE WATER HEATER CAUSED
BY EXPOSURE TO CORROSIVE VAPORS IS NOT COVERED BY THE
WARRANTY. DO NOT OPERATE THE WATER HEATER IF EXPOSURE
HAS OR WILL OCCUR. DO NOT STORE ANY POTENTIALLY CORROSIVE
COMPOUNDS IN THE VICINITY OF THE WATER HEATER.
WARNING
Liquefied petroleum gases/propane gas are heavier than air and
will remain at floor level if there is a leak. Basements, crawl
spaces, closets and areas below ground level will serve as
pockets for accumulation of leaking gas. Before lighting, smell
all around the appliance area for gas. Be sure to smell next to
the floor.
IF YOU SMELL GAS:
Do not try to light any appliance.
Do not touch any electric switch; do not use any telephone in
your building.
Immediately call your gas supplier from a neighbor’s
telephone. Follow the gas supplier’s instructions.
If you cannot reach your gas supplier, call the fire
department.
DO NOT OPERATE APPLIANCE UNTIL THE LEAKAGE IS
CORRECTED!

Installation (Locating The Water Heater) continued-
WARNING
DO NOT ATTEMPT TO LIGHT ANY GAS APPLIANCE IF YOU ARE NOT
CERTAIN OF THE FOLLOWING:
Liquefied petroleum gases/propane gas and natural gas have an
odorant added by the gas supplier that aids in the detection of the
gas.
Most people recognize this odor as a “sulfur” or “rotten egg” smell.
Other conditions, such as “odorant fade” can cause the odorant to
diminish in intensity, or ”fade”, and not be as readily detectable.
If you have a diminished sense of smell, or are in any way unsure of
the presence of gas, immediately contact your gas supplier from a
neighbor’s telephone.
Gas detectors are available. Contact your gas supplier, or plumbing
professional, for more information.
The water heater must be located close enough to the outside wall to keep the
venting distance within the maximum distance described in the installation
instructions. Read the venting section in this installation instruction manual
before locating the water heater.
This water heater must be located in an area where leakage of the tank or
water line connections and the combination temperature and pressure relief
valve will not result in damage to the area adjacent to the water heater or to
lower floors of the structure. When such locations cannot be avoided, a suitable
drain pan adequately piped for proper drainage, must be installed under the
water heater. The pan must not restrict combustion airflow. The drain pan
must have a minimum length and width of at least 4 in. (10.2 cm) greater than
the diameter of the water heater and must not restrict proper combustion air
flow to the water heater. The drain pan, as described above, can be purchased
from your plumbing professional. The drain pan must be piped to an adequate
drain. The piping must be at least 3/4 inch (1.9 cm) in diameter and pitched for
proper drainage.
It is recommended that a minimum clearance of four (4) inches (10.2 cm) be
provided on the side of the water heater for servicing and maintenance of the
combination temperature and pressure relief valve.
Note: For California installation this water heater must be braced,
anchored, or strapped to avoid falling or moving during an earthquake.
See instructions for correct installation procedures. Instructions may be
obtained from California Office of the State Architect, 400 P Street,
Sacramento, CA 95814.

NOTICE
For installations in Canada, field supplied plastic vent piping must comply
with CAN/CGA B149.1 (latest edition) and be certified to ULC S636. The
supplied vent connector and vent termination are certified as part of the
water heater.
Venting System Condensation
Condensate formation does not occur in all installations of power vented
heaters, but should be protected against on installations where condensation
can form in the venting system.
Formation of condensation in the venting system of Power Vented water
heaters is dependent upon installation conditions including, but not limited to:
ambient temperature and humidity of installation location;
ambient temperature and humidity of venting space;
vent distance and slope;
and product usage.
In order to effectively control condensate from adversely affecting the
mechanical components of the water heater several methods may be
employed:
1. For horizontal installations the vent pipe can be installed with a
downward slope (not less than 1/8" nor greater than ½” per foot
maximum) and away from the blower motor.
2. In order to prevent condensate from draining back into the blower
(vertical or horizontal runs), a fitting and drain hose is available as a
condensate trap kit (see Table 1 for service part numbers). The tubing
provided is to drain any accumulated condensate away from the water
heater and to a suitable drain. The kit comes complete with instructions
for proper installation of the fitting. If a Bradford White drain kit is not
purchased, the drain hose material must be either flexible PVC or
silicone hose with inside diameters as specified below. Hose clamps
that will ensure a leak proof connection at the drain hose must also be
used. Hose clips will be required to create a 6” diameter loop in the
drain hose routing below the jacket head.
50, 65 and 75 gallon powered direct vent models use 3/8” I.D. flexible
PVC or silicone hose.
