Record the fill volume of calcium

hydrogen carbonate on pageĂ14.

Please note:

Observe the " ater quality

requirements" on pageĂ24.

Fully opening the flue outlet damper and locking it open

8. Check all gaskets/seals and plugs

for leaks and re-tighten, if

necessary.

Please note:

In addition, we recommend you

check all heating water

connections after approx.

500Ăhours operation for leaks

(see pageĂ10).

Further details of the individual steps (cont.)

Pulsation noises

Independent of the make of boiler, burner or flue gas system, gas-tight flue

systems can create pulsation noises.

A change of resonance may be effected by rotating the damper fitted into the

flue outlet.

1. Loosen MĂ1 nutĂA in handleĂB

of damperĂC.

2. Adjust the handle until all

pulsation noises have ceased

(the handle mirrors the damper

position).

3. Lock the damper with MĂ1 nutĂA.

4. If necessary, readjust the burner.

Initial start-up, inspection and maintenance

Further details of the individual steps (cont.)

Opening the boiler door

1. Remove the gas supply pipe.

2. Loosen the screws on the boiler

door and open it.

¨Do not insert tools or other

objects into the combustion

chamber.

Separating the neutralising system from the boiler and

connecting the drain hose

1. Pull hoseĂD to the neutralising

system off stench trap plugĂE.

2. Unscrew stench trap plugĂE from

condensate drainĂF.

3. Clean the inside of condensate

drainĂF with a plastic brush.

4. Connect drain hoseĂGĂto

condensate drainĂFĂand run to a

sewer.

Initial start-up, inspection and maintenance

Further details of the individual steps (cont.)

Cleaning the combustion chamber and heating surfaces

Thoroughly clean the combustion

chamber and heating surfaces with a

water jet.

¨Do not use a wire brush or sharp

objects.

Scratches or other damage to

components which are in contact

with flue gases should be avoided.

Components which are in contact

with flue gases should not come

into contact with pure iron,

otherwise corrosion damage will

result. Use plastic brushes, if

necessary.

For normal cleaning, rinse the

heating surfaces with a water jet.

However, you may use cleaning

agents if you notice stubborn

residues, surface discolouration

or soot deposits.

When doing so, please observe the

following:

HOnly use solvent-free cleaning

agents. Ensure that no solvent

enters between the heat exchanger

and the thermal insulation.

HRemove soot deposits with alkaline

agents containing surfactants (e.Ăg.

FauchĂ6 *1).

HCombustion residues may create

thin, yellow-brown surface

discolouration as well as hard

deposits, which may only become

visible after removing the soot

deposits. Use slightly acidic,

chlorine-free cleaning agents

based on phosphoric acid to

remove surface discolouration and

hard deposits (e.Ăg. Antox Ă75ĂE*1).

HRemove loosened deposits from

the heat exchanger and thoroughly

rinse the heating surfaces and the

flue gas collector with a water jet.

protective clothing, if necessary.

¨ĂSafety instructions

Only open the heating water connections after the boiler has been

depressurised.

Only drain the boiler with a vacuum pump when the boiler vent is open.

1. Loosen the screws of top

panelsĂHand remove the panels.

2. Check sensor wellĂK and all

heating water connections for

leaks.

3. Position the top panels and secure

with screws.
