1.5 Precautions for installation
■
Piping for heating and hot water should be cleaned before connecting to the unit.
Lime scale accumulation can reduce the life of the equipment, reduce efficiency and waste fuel. Boiler failure due to
lime or scale buildup voids the warranty.
Check the metal tag on the relief valve and compare it to the heater’s rating plate. The pressure rating of the relief valve
must not exceed the working pressure shown on the rating plate of the heater. In addition, the hourly heat capacity
rated temperature discharge capacity of the relief valve shall not be less than the input rating of the 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 boiler needs a large quantity of air for combustion, the specified vent must be
installed. Incomplete combustion will occur and prevent normal operation of the boiler.
For safe operation, an ample supply of air must be provided for proper combustion and ventilation in accordance with the national fuel
gas code or applicable provisions of the local building codes (latest editions). 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 boiler should be at least 600mm away from electric appliances.
The boiler is set up for AC 220V, 50/60Hz.
The flow of combustion air to the boiler must not be obstructed.
The boiler area must be kept clear and free from combustible materials, gasoline and other flammable vapors and
liquids.
■
Flue made of 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 boiler.
■
Do not place flammable item near the boiler.
Never place combustibles such as vinyl bags,
match, thinner, etc on boiler.
