Vapors from flammable liquids will explode
and catch fire causing death or severe burns.
Do not use or store flammable products such as
gasoline, solvents or adhesives in the same room or
area near the water heater.

Keep flammable products:
1. far away from the water heater,
2. only in approved containers,
3. tightly closed, and
4. out of childrens reach.
This water heater has a main burner and automatic
ignition system.
The ignition system:
1. can come on at any time.
2. will ignite flammable vapors.
Vapors:
1. cannot be seen,
2. are heavier than air
3. go a long way on the floor, and
4. can be carried from other rooms to the pilot flame by
air currents.
Do not install this heater where flammable products
will be stored or used unless the main burner and pilot
flames are at least 18 inches above the floor. This will
reduce but not eliminate the risk of vapors being ignited
by the main burner or pilot flame.

DANGER
DO NOT USE THIS WATER HEATER WITH ANY GAS OTHER
THAN THE ONE LISTED ON THE DATA PLATE. This water
heater is equipped for use with one type gas only. CHECK THE
DATA PLATE ON THE WATER HEATER JACKET FOR THE
CORRECT GAS. FAILURE TO USE THE CORRECT GAS CAN
CAUSE PROBLEMS WHICH CAN RESULT IN DEATH, SERIOUS
BODILY INJURY OR PROPERTY DAMAGE. If you have any
questions or doubts consult your gas supplier or gas utility
company. Water heaters using bottled propane or liquefied
petroleum gas (LPG) are different from natural gas models. A
natural gas water heater will not function safely on bottled
propane or liquefied petroleum gas (LPG) and a propane gas
water heater will not function safely on natural gas. Do not
attempt to convert a water heater from natural gas to LPG or
from LPG to natural gas.

WHEN REMOVING PURGED
GASES FROM A PIPING
SYSTEM, DO NOT CREATE
A HAZARDOUS CONDITION
BY DISCHARGING THE
GASES INTO A CONFINED
AREA OR IN AN AREA THAT
CONTAINS AN IGNITION
SOURCE.




Water temperature over 125°F can cause severe burns
instantly or death from scalds.
Children, disabled and elderly are at highest risk of being
scalded.
See the instruction manual before setting the water
temperature at the water heater.
Feel the water before bathing or showering.
Temperature limiting valves are available for limiting
domestic hot water temperatures.
