INSTALLATION
Locating The Water Heater
DO NOT install the water heater in any location where gasoline or
flammable vapors are likely to be present.
Water Heaters in residential garages must be installed so that all
burner(s) and burner ignition device(s) are located not less than 18
inches (46 cm) above the floor and must be located or protected to
avoid physical damage. For other installations refer to local codes.
In the absence of local codes, the water heater must be installed in
compliance with the National Fuel Gas Code, ANSI Z223.1 - (Latest
Edition) and/or in Canada, CAN/CGAB149 Installation Codes (Latest
Editions).
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.
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.
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 drain pan must not restrict combustion air flow. The drain
pan must be no greater than 1-½ inches (3.8 cm) deep and have a minimum
length and width of at least four (4) inches (10.2 cm) measured from the
jacket of 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.
MINIMUM CLEARANCES
This installation must allow access to the front of the water heater and adequate
clearance must be provided for servicing and operating this water heater. The
water heater may be installed on either a combustible or non-combustible
floor. If the water heater is to be installed directly on carpeting, it must be
installed on top of a metal or wood panel extending beyond the full width and
depth of the appliance by at least three (3) inches (7.6 cm) in any direction or,
if the appliance is to be installed in an alcove or closet, the entire floor must be
covered by the panel. The minimum clearances to combustibles for this water
heater are: zero (0) inch (0 cm) from the sides and rear, five (5) inches (12.7
cm) from the front of the jacket, zero (0) inch (0 cm) from the vent connector
and fifteen (15) inches (38.1 cm) from the jacket top.
VENTING
This venting section is divided into two parts. Part I will cover
venting specifications for 48 Gal - 65,000 BTU (181.7 L - 19.1 kW/
Hr), 65 Gal -65,000 BTU (246.1 L - 19.1 kW/Hr), and 75 Gal -
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.
WHAT TO DO IF YOU SMELL GAS
• Do not try to light any appliance.
• Do not touch any electrical switch; do not use any phone in your
building.
• Immediately call your gas supplier from a neighbor’s phone. Follow the
gas supplier’s instructions.
• If you cannot reach your gas supplier, call the fire department.
DO NOT OPERATE APPLIANCE UNTIL LEAKAGE IS CORRECTED!
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.
WARNING
Failure to adhere to these installation and operating
instructions may create a hazard to life and property and
will nullify the warranty.
WARNING
Water heaters are heat producing appliances. To avoid damage or injury there shall
be no materials stored against the water heater or vent-air intake system and
proper care shall be taken 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.
