ウォーターヒーター ATTACK PZO 80のPDF 取扱説明書をオンラインで閲覧またはダウンロードできます。ATTACK PZO 80 12 ページ。 Direct heated gas tanks for d.h.w

WARNING!

Because of possible condensation of vapour it is not recommended to set up water

temperature to a value lower than 50°C. For running water it is necessary to mix water in the

fitting.

PUTTING THE WATER TANK OUT OF OPERATION

The procedure is following:

 Turn the control button into the position

 Stop gas supply to the appliance

 For putting the appliance back to operation it is necessary to follow previous chapters

WARNING!

Control elements of the gas fitting can not be manipulated violently. Damage can cause gas

release and even explosion. If turning the control element causes problems, service should

be called immediately.

SAFETY DEVICE

The procedure of burning is protected by flame fuse that closes gas supply automatically

when ignition flame goes off. Opening time of the fuse is about 8 seconds but it can not

overcome 15 seconds. Closing time is about 45 seconds but it can not overcome 60 seconds.

TEST OF THE DEVICE

When putting the device to operation the organization is obliged to check:

 safety times of flame fuse

 adjustment of the appliance to a certain thermal output

 the procedure of burning the main burner from ignition flame (must be continuous)

 whether the operation thermostat is working

 whether the safety valve is working

 whether the device is gas resistant and water resistant

 whether the draught breaker is working and waste gas is exhausted properly

 documentation of the device

POSSIBLE FAILURES – CONDENSATION OF VAPOUR

Vapour present in waste gas can condensate and then drop on hot surfaces. In this case some

hiss and crackle can be heard. After heating water this sound will stop.

CONDENSATION OF VAPOUR CAN HAPPEN IN FOLLOWING CASES:

 New storage tank is filled with cold water for the first time.

 Gas burning starts but water is still cold.

 If in a short time a big volume of water was released and water coming into the boiler is too

cold. If this occurs too often, it is necessary to set up the regulator of temperature to a higher

value.
