BE SURE TO FOLLOW THE FOLLOWING INSTRUCTIONS.
The instructions which are contained in this manual are classified into the following two types, which are
"WARNING" and "CAUTION". These instructions are intended to provide important information for safe
operation.
"WARNING" indicates the possibility of causing the user a fatal accident or serious injury if the water heater
is incorrectly operated.
"CAUTION" indicates the possibility of causing the user injuries or material damages if the water heater is
incorrectly operated.
WARNING
1. Never use any fuel other than ASTM (AMERICAN SOCIETY FOR TESTING AND MATERIAL) D3699 1-K
Kerosene, D396 Low Sulfur No. 1 Fuel Oil, or ASTM D975 Ultra Low Sulfur Diesel (ULSD). You are rec-
ommended to use the low sulfur fuel.
NEVER USE GASOLINE! Use of such fuels can result in an explosion and/or fire and cause injury.
2. Improper installation, adjustment, modification, or service and maintenance by an unauthorized person
may cause SERIOUS UNIT DAMAGE, BODILY INJURY, HAZARD OR PROPERTY DAMAGE. This unit
should be installed by a licensed, authorized person(s) due to the necessity of making electrical, water
and fuel connections. Refer to the installation manual and the operation and maintenance instructions
for assistance, or consult your dealer for further information.
3. HAZARD OF ELECTRICAL SHOCK! Before removing any access panels of water heater for service, make
sure the electrical supply to the water heater is shut off. Failure to do this may result in HAZARD, SERI-
OUS BODILY INJURY, OR PROPERTY DAMAGE.
4. Check and comply with all local, state and ANSI Z21.22 codes that may apply to water heater(s) before
beginning the installation.
5. This water heater is designed to be used no more than 4,922 FT. (1,500 m) above sea level. When the
water heater is installed with the flue pipe at altitude of higher than 1,640 FT. (500 m) ~ 4,922 FT. (1,500
m) above sea level or is installed with the chimney adapter at altitude of higher than 3,280 FT. (1,000 m)
~ 4,922 FT. (1,500 m), adjustments are needed.
Ask your local dealer.
The water heater may have a failure of combustion at a high altitude.
6. RISK OF INDOOR AIR POLLUTION AND FIRE. Be sure the exhaust pipe is properly installed and connect-
ed. Aluminum tape provided may be used for sealing exhaust pipe connections.
CAUTION
1. Keep the area around the unit clean and free of flammable materials.
2. RISK OF FIRE AND ELECTRIC SHOCK. Do not apply any excessive force or pressure to the power supply
cord. Make sure the plug is free of dust. Be sure plug fits the receptacle securely.
3. Install a temperature and pressure relief valve on the installation mouth in accordance with local, state
and ANSI Z21.22 codes. See the page 6 for more details.
4. When No. 2 fuel oil is used in an area where the temperature becomes less than 25˚F (-4˚C), it is recom-
mended the use of an additive with the fuel to prevent congealing. Check with a fuel supply company
for the proper additive and mix.

SELECTING A LOCATION
CAUTION: When No. 2 fuel oil is used in an area where the temperature becomes less than 25˚F (-4˚C), it is
recommended the use of an additive with the fuel to prevent congealing. Check with a fuel supply
company for the proper additive and mix.
Select a place to install the water heater where water and electric supply are easily available.
1. Select a place which is free of moisture, water spills, pools or snow.
2. Select a place which draining can be done easily.
3. Select a place which the fuel tank can be installed safely.
4. Select a place which is free of combustible substances.
5. The surrounding walls should be finished with noncombustible materials (concrete block, mortar, or
plaster are allowable).
6. The floor on which the water heater is installed must prevent intensive vibrations or shock and must be
strong enough to bear the weight of the water heater.
7. Select a place where proper maintenance and control can be provided for the unit after installation.
8. Select a place sheltered from weather.
9. Install the unit on a noncombustible surface in a stable position. If installing on combustible floor, the
