Maintenance and cleaning
The water grill must be kept clean and efficient to assure its performances. In the case of troubles do not
tamper any part of it but call technical assistance; all special maintenance and reparing must be done by
specialised technicians. Check periodically the condition of the gas pipes, fittings and burners. For
routine cleaning proceed as follows and observe the recommendations:
•
Before performing any job of maintenance or cleaning is necessary to close the gas supply found at
the top of the appliance and let the grill cool down.
•
Clean the steel parts daily with soapy water rinse and dry thoroughly. Neither use products
containing chlorine (bleach, hydrochloric acid, etc.) nor steel wool, brushes or scrapers that could
produce rust. Do not leave food (as acid food, salt, lemon, etc.) on steel parts as it could ruin them.
•
Never wash the appliance with direct, high-pressure jets of water.
•
Do not use corrosive substances such as hydrochloric acid when cleaning the supporting table.
Warning! if the lighting and control devices are difficult to use, contact the manufacturer promptly that
will provide the necessary assistance.
•
It is consulted to the user to undersign a contract of maintenance with technical personnel that
foresees at least one full check-up annually.
•
We specifically recommend regular checking to make sure the ignition source and the flame
regulation are clean.
•
The gate valve must be checked at least once a year and, if necessary, restored the protection of
specific oil.
•
If such an accurate observance of the contained instructions in this manual are observed, NORTH
appliances will allow perfect use and performances for a long time.
The manufacturer cannot be held responsible for any damage caused to property, human beings or
animals due to misuse of the appliances or non-observance of instructions included in this manual.
