of the healer
It is easy to clean the exterior of the heater, because the smooth enamelled sheet metal
body completely encloses all vital components, and there are no corners where dust or
dirt could collect. During the operation of the heater dust and combustion particles deposit
on the heat exchanger, burner, etc. These deposits should be removed by a qualified
fitter during periodical servicing, prior to checking and adjusting appliance for correct and
efficient operation.
A hinl how to reduce calciflcailon of the heater
After every hot water tapping first turn gas switch one notch to the right, in order to show
off the gas supply, and only when cold water begins to run, close the tap. By doing this,

Slrooting
When it becomes necessaryto lubricate moving parts, we strongly recommend the use of
special VaillantGrease.
Loss of elticiency can be caused by:
(Town gas - Natural gas)
a) Gas pipe too small.
b) Gas meter too small. Replace.
c) Gas pipe or gas strainer clogged. Remove heater assemby, disassemble gas
strainer and clean. Before reassembly blow out gas pipe. Water in gas pipe.
Drain gas pipe or preferablychangethe routing of same.
(Bottled gas)
a) Gas pipe is too long or too small a bore - larger sized pipe required.
b) Gas pipe is obstructed- clogged, pinched etc.
c) Gas feed pressure too low. Check pressure at regulator outlet - gas filter may
be clogged-gasfeed pressureto burner is below requiredvalue.

Frequently Answers and Questions

How do I start the heating unit?
The ignition procedure must be repeated if the rotation handle returns to the shut-off position. The heating unit will be ready for operation when the rotation handle is turned to the right to the operation position.
How do I shut off the heater?
The heater is still ready for use when the warm water tap is shut off and the gas switch is turned one notch to the right. To completely shut off the heater turn the gas switch to the right until it stops at the "Off" position.
How do I clean the heater?
The exterior of the heater is easily cleaned because the smooth enamelled sheet metal body completely encloses all vital components. During the operation of the heater dust and combustion particles deposit on the heat exchanger, burner, etc. These deposits should be removed by a qualified fitter during periodical servicing, prior to checking and adjusting appliance for correct and efficient operation.
