About LP gas products
“Certification validity period expiration warning” is a function to give a warning when 10 years and 6 months have elapsed since the manufacturing of the product, and then it shuts off the gas supply 40 days later.
The time when the certification validity period expiration warning/shutoff function came to be equipped is as follows:
SY25: October 2010
・SY4 and SY6: October 2010
・EY25 and EY4: August 2009 (start of sales)
・EBY6: October 2012 (start of sales)
・EBY10 and EBY16: May 2014 (start of sales)
When you re-insert the power plug of the gas alarm into a receptacle, the indication will automatically go off in about 30 minutes.
There is a possibility of shutoff due to failure to connect the alarm. Confirm that the alarm is positively connected.
The possible causes are as follows:
・After connecting the alarm, it takes 2 to 3 minutes for the gas meter to recognize the alarm. Then, conduct the recovery operation.
・The signal lines for interlocking between the gas meter and alarm may be connected in reverse or short-circuited. Check the condition of the signal lines, and then conduct the recovery operation.
Gas meter
When gas alarm with plug disconnection function is interlocked, a plug disconnection symbol will be displayed after 30 to 40 minutes have passed.
※ In restoration of the product from power failure, the indication goes off in 30 to 40 minutes, but Extension 2 and Upper limit fix settings are also cleared. It is necessary to set them again.
Alarm
As the power lamp goes off and the device sops functioning, it will not operate.
Shutoff valve
In a power failure state, the shutoff valve maintains the normal condition.
Arorizer
When the hot water temperature is 60°C or higher and the metal temperature (VP-S30EC) is 40°C or higher, the arorizer keeps supplying the gas. However, when either of the temperatures drops, the gas supply stops. (Even after the power is restored, the stopped state continues.)
About city gas products
By measuring the time it takes for ultrasonic waves from sensor A to arrive at sensor B as well as the time it takes for ultrasonic waves from sensor B to arrive at sensor A, the meter measures the gas flow speed, and based on the flow speed, calculates the gas flow rate.
The technology to measure in units of billionths of a second has made accurate measurement possible.
