■ Piping for heating and hot
water should be cleaned
before connecting to the unit.
CAUTION
Lime scale accumulation can reduce the life of the
equipment, reduce efficiency and waste fuel. Water heater
failure due to lime or scale buildup voids the warranty.
Check the metal tag on the relief valve and compare it to
the water heater’s rating plate. The pressure rating of the
relief valve must not exceed the working pressure shown on
the rating plate of the water heater. In addition, the hourly
BTU rated temperature discharge capacity of the relief valve
shall not be less than the input rating of the water heater.
NO VALVE IS TO BE PLACED BETWEEN THE RELIEF
VALVE AND TANK. DO NOT PLUG THE RELIEF VALVE.
The drain line connected to this valve must not
contain a reducing coupling or other restriction and
must terminate near a suitable drain to prevent water
damage during valve operation. The drain line shall be
installed in a manner to allow complete drainage of
both the valve and line.
DO NOT THREAD, PLUG OR
CAP THE END OF THE DRAIN LINE.
■ The water heater needs a large quantity of air for
combustion, the specified vent must be installed.
If not incomplete combustion will occur and
prevent normal operation of the water heater.
WARNING
For safe operation, an ample supply of air must be
provided for proper combustion and ventilation in
accordance with the national fuel gas code, ANSI
Z223.1 or CAN/CGA-B149.1 or B149.2(latest editions)
or applicable provisions of the local building codes. An
insufficient supply of air may result in a yellow, luminous
burner flame, carboning or sooting of the finned heat
exchanger, or create a risk of asphyxiation. Do not
obstruct the flow of combustion and ventilation air.
NEVER OPERATE THE HEATER UNLESS IT IS
VENTED TO THE OUTDOORS AND HAS ADEQUATE
AIR SUPPLY TO AVOID RISKS OF IMPROPER
OPERATION, FIRE, EXPLOSION OR ASPHYXIATION.
■ The water heater should be
at least 24” away from
electric
appliances.
The
water heater is set up for
AC 115V 60Hz.
WARNING
The flow of combustion air to the water heater
must not be obstructed.
The water heater area must be kept clear and free
from combustible materials, gasoline and other
flammable vapors and liquids.
■ Flue made of schedule 40
PVC or stainless steel.
■ To facilitate the discharge
of exhaust gas, the flue
should be installed with
fewest possible bents and
curves. The flue should
have a diameter larger than
that of the flue of the water
heater.
■ Do not place flammable
items near the water heater.
Never place combustibles
such as vinyl bags, matches,
thinner, etc on water heater.
CAUTION
Read first before connection to power supply
