The following information should be read before starting up the boiler!

Dear Customer,

With the Hoval TopGas

®

, you have acquired a product manufactured according to the 

state-of-the-art and to the highest quality standards.
Please ensure that the delivery is consistent with your order and check it for com-
pleteness. Also check for possible damage incurred during transport and inform the 
nearest Customer Service centre of any damage. For insurance reasons, it will not 
be possible to accept any subsequent claims.
For the correct installation and operation of your Hoval TopGas

®

, all applicable laws, 

regulations and standards must be complied with; in particular the regulations of the 
responsible energy supply company. In case of queries, please contact your specialist 
installer or the nearest Hoval Customer Service centre.
Assembly or installation of the boiler may only be carried out by trained personnel 
from a licensed installation company. Before commissioning, an installation inspection 
and approval of the overall installation by the installer are required. 
To guarantee safe and trouble-free operation, operate your Hoval boiler in accordance 
with these operating instructions at all times.
The boiler may only be used for its intended purpose and with fuels for which it was 
designed and which have been approved by Hoval. 
Do not carry out any modifications to the system, otherwise all claims under the war-
ranty will be waived. Conversion kits must be installed and the installation approved 
by authorised installers or by the Hoval Customer Service.
Reliable and safe functioning of a gas boiler, as well as the achievement of optimum 
efficiency and clean combustion are only possible and guaranteed if the system is 
serviced and cleaned at least once per year.
In the event of a fault or in the event of damage, please contact the Hoval Customer 
Service to inquire about the necessary repairs. In the meantime, shut down the unit 
to avoid any damage.
With the acquisition of a Hoval unit, you also obtain comprehensive warranty cover, as 
indicated in the warranty conditions on the warranty pass for your unit.
This warranty is, however, dependent on observance of the operating and assembly 
instructions and on compliance with the applicable legal regulations. Non-compliance 
with the above will invalidate all liability and warranty claims against Hoval.
Provided it is used correctly, your Hoval boiler will ensure you enjoy a well heated 
home for many years.

Hoval Customer Service

If you have any doubts with regard to the operation of your Hoval boiler, or if minor 
faults affect its correct functioning, please contact the nearest Hoval Customer Service 
centre. A telephone call is often all you need to solve minor problems. Our trained 
Customer Service staff will do everything in their power to help you.
If a problem cannot be solved in this way, a service technician will visit you in order 
to correct the damage. We hope you will understand that, except in urgent cases, 
this will not always be immediately possible.
Take advantage of the Hoval Customer Service offerings to prolong the service life of 
your boiler, and inquire about a service agreement. Your Customer Service consultant 
will be pleased to advise you!
You will find the addresses on the last page.
