WARNINGS

 

9

The heating unit must be used for the purpose for which 

it was specifically designed and produced. Any whatsoev-

er contractual or extra-contractual liabilities for damages 

caused to persons, animals or objects due to errors in in-

stallation, adjustment, maintenance and improper usage 

are to be excluded.

 

9

Installation must fully comply with provisions of the law 

in force and instructions provided by the manufacturer to 

ensure safety and correct functioning, always calling upon 

professionally  qualified  technical  personnel  who  will  is-

sue the declaration of conformity for the installation ac-

complished with good workmanship, in compliance to 

regulatory provisions in force and guidelines given in this 

handbook. The appliance must be installed in appropriate 

premises and together with the specific systems installed 

according to the law.

 

9

Commissioning will be carried out by personnel from the 

authorized Technical Assistance Service only and within 8 

days from when the appliance was installed. After initial ig-

nition the Technical Assistance Service will fill in the warran-

ty certificate, leaving the user their part to be kept, marking 

the beginning of the period of guarantee at the terms and 

conditions specified on the relative slip.

 

9

The appliance in its original packing may be exposed to 

temperatures between 4°C and 40°C. Do not expose the 

appliance to bad weather conditions after it has been un-

packed, anyhow to temperatures below 4°C or above 40°C 

until it has been connected up to the water, gas and elec-

tricity mains so as to be able to activate the frost protection 

systems described in paragraph 6.2.7.

 

9

Check that the product is complete, undamaged and as or-

dered as soon as you receive it. Report any discrepancies or 

damage to the 

R

 dealer who sold it.

 

9

In case of leaks, disconnect the heating unit from the mains, 

close the water from the mains and promptly contact the 

Technical Assistance Service.

 

9

Regularly check that the condensate drain is free from ob-

struction.

 

9

Regularly check that the working pressure of the water cir-

culation system, when cold, is below the maximum limit 

specified for the appliance. If not, contact the Technical As-

sistance Service.

 

9

Maintenance jobs on the heating unit must be carried out 

by personnel from the authorized Technical Assistance Ser-

vice. Maintenance must be performed at least once a year. 

Correct maintenance is essential for safety as well as for 

the efficiency and long working life of the product. Proper 

maintenance keeps consumption and emissions down, and 

ensures that the product continues to operate reliably over 

time. Analyse the combustion fumes before commencing 

maintenance. The results of fume analysis can give a clear 

idea of what servicing or repairs are needed.

 

9

We recommend cleaning inside the exchanger once a year, 

extracting jet and burner and removing any installation de-

bris by suction. This operation will be done by personnel 

from the Technical Assistance Service only.

 

9

The warranty slip endorsed during the course of commis-

sioning will have to be produced for any servicing required 

during the guarantee period. The manufacturer shall not be 

held liable for any damages caused by mishandling, im-

proper use or errors in installation, use and maintenance 

work on the appliance. In the event of breakdown or mal-

function switch off the appliance, avoiding to make any at-

tempt to repair it and contact the Technical Assistance Ser-

vice.

 

9

This manual must be read carefully for the boiler to be used 

rationally and safely, and must be kept with care so as to 

be on hand where required by the technician or installer, to 

facilitate the appropriate installation, running and main-

tenance of the boiler. 

R

 will not be held liable for any 

translations possibly giving rise to wrong interpretation. 

This manual is an integral part of the heating unit and must 

consequently be kept with care and must ALWAYS accom-

pany the boiler even when passed on to another owner or 

user or transferred to another installation. Ask the Techni-

cal Assistance Service for another copy if it should be lost or 

damaged.

 

0

Children and people with disabilities or without experience 

and specific knowledge are forbidden to use the heating 

unit unless they are assisted by a qualified person respon-

sible for their safety.
