panel and the boiler should be carried out by qualified
personnel in compliance with the reference regulations and
standards.

The burner should be purchased separately, this manual
contains only information regarding the boilers and the
boiler warranty does not extend to the burner. It is necessary
to consult the burner's instruction manual and have the
Warranty Certificate issued for the burner by the dealer
where it was purchased.
9
Before starting the burner, make sure that the front door of
the boiler is closed tight and that the burner connections
have been carried out correctly.

Do not touch the hot water pipes and the flues gases
discharge pipe when the boiler is running.
1.1
General warnings
The boiler models in this manual are delivered fully assembled.
9
The cast iron boilersRTT 29-79 are designed for heating using
water and/or supplying hot water systems and have been
designed with technologies and materials suitable for this
purpose. Use the product only for this intended use.
9
The installation of the appliance should be carried out on a
base that is suited to the weight and the dimensions.
9
The base of the boiler should be positioned and oriented in
such a way as to leave sufficient space on the sides of the
appliance to meet safety requirements and permit access to
the boiler for maintenance and repairs.
9
The commissioning and initial ignition of the boiler should
only be carried out by specialised installers.
9
It is forbidden to put or pump water into the boiler or the
hydraulic system when the appliance is running and is hot.
9
Before putting water in the boiler or the system, it is
necessary to wait for the water temperature to reach 40°
C. When putting water into the system, always run the
circulation pump to prevent breaking the elements.
9
When the boiler is off for a long period or when carrying out
repairs, maintenance or cleaning, the electrical supply must
be disconnected using the master switch.
9
Especially in summer, when the boiler is off for a long period,
to avoid problems of incrustation in the circulation pumps,
the boiler must be switched on 1-2 times a month and the
circulation pumps operated for at least 5 minutes. Limescale
in the water can cause problems if the pump is unused for
a long period.
9
Choose a boiler with the right dimensions for the project
in full compliance with applicable regulations. If the wrong
size is chosen, the performance will suffer.
9
The RTT 29-79 boilers are only to be used for heating. For the
production of domestic hot water, it is necessary to use a
storage heater or another heat exchanger. For it to operate
efficiently, pay special attention to the size of the domestic
hot water circuit.
9
The RTT 29-79 boilers are delivered without the burner. To
choose the most suitable burner and keep the performance
high, contact our technical personnel.
9
If the boiler goes into lockout automatically because of
overheating, do not put cold water inside to get it going
again. Wait until the boiler cools down, and try to restart
it. If this does not happen, contact the Technical Assistance
Service.
9
Periodically check the boiler and the burner. If these periodic
checks are not carried out, the performance will worsen and
there will be an increase in fuel consumption. The periodic
and annual controls of the boiler should be carried out
precisely and at the pre-established time. Natural gas is a
clean fuel and does not dirty the appliance so much. Liquid
fuel burners, on the other hand, dirty the appliance a lot,
and the boiler controls and maintenance operations are
necessary to ensure a high performance and a long life.
9
Repairs and periodic controls of the boilers RTT 29-79 should
be carried out by specialised technicians. This manual
contains an explanation of the user's responsibilities and
the information required for using the boiler. Beyond these
operations, the boiler should only be commissioned by the
user or by one of our technicians. Do not try to adjust the
boiler or tamper with any components.
