Gas bath boiler

Problems that could be caused by incorrect usage

It is dangerous to improperly use a product. Please consult the user manual for proper usage.

Actual case Since a bath tub was unplugged, the bath tub was heated with no water in it, and was deformed.
Actual case Since the bathwater was drained when a drainage outlet was clogged, the equipment was submerged under water, which caused abnormal ignition and the deformation of equipment.
Caution
When equipment is submerged underwater, water enters into the equipment. When it is subsequently used, the flame may burn stronger than before, causing fire and damage to the equipment or incomplete combustion.. When an incomplete combustion occurs due to problems with the equipment’s air supply and exhaust openings, generated carbon monoxide may filter into the bathroom. In the worst case, this could result in a fatality.
To avoid submerging equipment under water, please frequently clean the drainage outlet so it does not become clogged.
Actual case Because a user repeatedly attempted to ignite the boiler, the equipment filled with gas. When it did ignite, it did so abnormally, which deformed the equipment.
Caution

Precautions to prevent abnormal ignition (especially for balanced-flue system bath boiler with a chimney)
When a pilot burner does not light within 15 seconds, please return the appliance’s valve switch to the [Stop] position. After waiting for two minutes to let the gas from the attempted ignition escape, you may try to ignite the pilot burner again.
When changing the switch from the [Pilot burner] position to the [Stop] position, please wait for two minutes before attempting to ignite the burner again.
If the burner’s flame shuts off, or the temperature of the water drops, turn the hot-water supply switch and the appliance’s valve switch to their [Stop] positions. Please wait for 20 minutes before operating the equipment again.
If you do not wait long enough before attempting to reignite the burner, you may cause an abnormal ignition, resulting in a loud noise and/or equipment deformation.
Actual case There was a water leak from the equipment, but the user kept using it without repair. Due to the water leakage through the internal parts, the gas components were corroded. Then, gas was leaked, which caused abnormal ignition and the deformation of equipment.
Actual case A user used a spray can in the bathroom immediately before igniting the pilot burner, causing the combustible gas from the spray can to catch on fire.
Actual case Since equipment was used while the air supply opening connected to the outdoors was closed, there was no sufficient air, and incomplete combustion occurred.
Actual case A user used a fan while using a bath boiler, and the exhaust air flew backward into the room.
Caution
When a bath boiler with a chimney (indoor, CF type) is used for heating bathwater or a shower, please do not use a fan in a kitchen.
Exhaust air in a bath boiler may flow backward, causing a risk of carbon monoxide poisoning.
