6.2. Maintenance by User 

a)

 

The boiler should be cleaned as necessary, without removing the cover panels. Before cleaning, put the main switch off 
and unplug the power cord. If the boiler surfaces are wet after the cleaning, the boiler should not be started until it dries. 

b)

 

The HCW pressure should be checked once a week, with replenishment of water as necessary – before replenishing, the 
boiler temperature (the reading shown on the boiler thermometer) must cool down to below 40°C. Failing to met this 
requirement may lead to leaks or ruptures in the boiler body (caused by thermal shrinkage). 

c)

 

Checking tightness of the flue-gas duct. 

d)

 

If there is a gas leak, shut the gas supply valve and call a specialised service centre. 

e)

 

Checking and cleaning the filter and sludge separator: 

1.

 

Immediately after the First Heating; 

2.

 

After the first week of operation; 

3.

 

Regularly once per month; or once per quarter if the sedimentation rate is lower.
