Water heater edition
Fresh air is always required to completely burn the gas.
Recent housing structures are becoming more and more sealed to improve the air-conditioning effect. br> Therefore, if the water heater (water heater) that consumes a lot of gas is used for a long time in a closed room, the room will be short of oxygen, causing incomplete combustion and causing a dangerous poisoning accident. It will be. To prevent this, a water heater (water heater), etc. must be installed in an appropriate location, and appropriate air supply / exhaust equipment (ventilation fan, ventilation port, exhaust port, exhaust stack, etc.) must be installed.
No. 5 water heater
- According to the Fire Prevention Ordinance, the circumference of the water heater should be 4.5 cm or more on the side from the combustibles, and the water heater with a built-in heat shield hood should be 15 cm or more away from the combustibles (15 cm or more from the hood for the hood-mounted type). If a heat shield is attached above, keep it at least 10 cm away.
- Install in a place where sufficient ventilation (air supply, exhaust) can be obtained. Install so that the upper part of the device is below the upper end of the ventilation fan. The incomplete combustion prevention device may operate and may not catch fire. It may also cause equipment failure or shorten the service life.
* The size of the ventilation fan and the air supply port depends on the gas consumption of the equipment used at the same time in the room.
Reference table for the size of the ventilation fan - Please use this device in conjunction with the ventilation fan interlocking switch (sold separately) as much as possible.
- Even if the upper part of the device is 150 mm or more away, the upper surface and rear surface within 400 mm may be deformed or discolored due to exhaust heat if it is a painted surface, vinyl cloth, a hanging cupboard made of resin, or a thin veneer. Use gypsum board, etc. for effective protection.
