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 a hot water faucet to be open for several minutes
before you use any electrical appliance which is connected 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.
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 (National Sanitation Foundation) requirements, this water heater must be sealed to the
floor with sealant, in a smooth and easily cleanable way.
