WARNING
This water heater needs fresh air for safe operation and must be installed so there are provisions for
adequate combustion and ventilation air. Insufficient air supply will cause a recirculation of combustion
products resulting in contamination that may be hazardous to life. This will result in carboning or sooting of the
combustion chamber, burners, and flue tubes and creates a risk of asphyxiation.
This water heater requires its own separate venting system.
DO NOT
connect the exhaust vent into an
existing vent pipe or chimney.
Flammable items, pressurized containers or any other potential fire hazardous articles must never be placed
on or adjacent to the water heater. Open containers of flammable material should not be stored or used in the
same room with this water heater.
Insulation blankets are not required for this water heater. This water heater meets or exceeds the
ASHRAE/IES 90.1b (latest edition) standards with respect to insulation and standby loss requirements.
Hydrogen gas can be produced in an operating water heater that has not had water drawn from the tank for a
long period of time (generally two weeks or more).
HYDROGEN GAS IS EXTREMELY FLAMMABLE.
To
prevent the possibility of injury under these conditions, we recommend the hot water faucet to be open for
several minutes at the kitchen sink before you use any electrical appliance, which is connect to the hot water
system. If hydrogen is present, there will be unusual sounds such as air escaping through the pipes as hot
water begins to flow.
DO NOT
smoke or have open flame near the faucet at the time it is open.
WARNING
Prior to connecting the gas supply line to a gas fired water heater, ensure that the gas supply line
does NOT have moisture/water or dirt/scale inside the gas line. Commonly this check is done at the
lowest point in the gas distribution system prior to gas burning appliances.
Do
NOT
use this appliance if any external part to the tank has been submerged in water. You should contact a
qualified service technician to inspect the appliance and to replace any part of the control system including the
combination gas control which has been submerged in water. See the Gas Connections section of this manual
before servicing or replacing a water heater that has had any external part to the tank submerged in water.
WARNING
Liquefied petroleum gases/propane gas is 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 telephone in another building. Follow the gas
supplier’s
instructions.
•
If you cannot reach your gas supplier, call the fire department.
DO NOT OPERATE THE APPLIANCE UNTIL THE LEAKAGE IS CORRECTED!
NSF Compliance
To comply with NSF requirements this water heater must be sealed to the floor with sealant, in a smooth and
easily cleanable way.
