• Do not install the water heater where the exhaust will blow on outer
walls or material not resistant to heat. Also consider the surro-
unding trees and animals.
The heat and moisture from the water heater may cause discolo-
ration of walls and resinous materials, or corrosion of aluminum
materials.
As the heatproof temperature of wired sheet glass is approximately
half of that of general glass and it is breakable, the glass may break
because of exhaust gas if there is wired sheet glass in the exhaust
direction of equipment (approximately 1m or less). Be sure to avoid
the installation or change the exhaust direction.
• Avoid installation above gas ranges or stoves.
• Avoid installation between the kitchen fan and stove. If oily fumes or
a large amount of steam are present in the installation location, take
measures to prevent the fumes and steam from entering in the
equipment.
• Avoid installation in places where dust or debris will accumulate.
Dust may causing the performance of the fan motor to drop and
incomplete combustion to occur as a result.
• Install in a location where the exhaust gas flow will not be
affected by fans or range hoods.
• Take care that noise and exhaust gas will not affect neighbors.
• Avoid installation in places where special chemical agents
(e.g., hair spray or spray detergent) are used.
Ignition failures and malfunction may occur as a result.
• When you install the equipment, check the wall or ceiling around the
installation place is safe for fire protection or install the equipment
where the free space effective for fire protection can be ensured.
