to keep your boiler efficient and cheap to run. Technical Assistance Centres also stock any
original spare parts that might be required.
This instruction manual contains important instructions and precautions that must be
observed to ensure the trouble-free installation and efficient functioning of your RTQ r
boiler.
Please accept our renewed thanks for your purchase.
Riello S.p.A.
RTQ r boilers are covered by a SPECIAL WARRANTY that comes into force from the date
of validation by your local rTechnical Assistance Centre. Consult Yellow Pages to find your
nearest Centre.

GENERAL SAFETY INFORMATION
PRECAUTIONS
b The boiler is delivered in separate crates. Check
that it is complete, undamaged and as ordered as
soon as you receive it. Report any discrepancies or
damage to the dealer who sold it.
b In Italy, Law n° 46 of the 5th March 1990 requires
that this r RTQ boiler be installed by a qualified
installation company. On completion of the installa-
tion, the installer must issue the owner with a decla-
ration of conformity confirming that the installation
has been completed to the highest standards in
compliance with the instructions provided by r
in this instruction manual, and that it conforms to all
applicable laws and standards.
b The boiler must only be used for the purpose spe-
cified by rand for which it is designed. The
manufacturer declines all responsibility, contractual
or other, for damage to property or injury to per-
sons or animals caused by improper installation,
adjustment, maintenance or use.
b If you notice any water leaking from the boiler,
disconnect it immediately from the mains electricity
supply, shut off the water supply, and notify your
local rTechnical Assistance Centre or a quali-
fied heating engineer immediately.
b Periodically check that operating pressure in the
water circuit is over 1 bar but below the maximum
limit specified for the boiler. If this is not the case,
contact r’s Technical Assistance Service or a
professionally qualified heating engineer.
b If the boiler is not going to be used for an extended
period of time, contact r’s Technical Assistance
Service or a qualified heating engineer to have it
prepared for shut-down as follows.
- Switch the boiler OFF at the control panel and at the
mains power switch.
- Close the fuel cock and heating circuit water cock.
- Drain the central heating circuit if there is any risk of
freezing.
b The boiler must be serviced at least once a year.
b This instruction manual is an integral part of the
boiler. It must be kept safe and must ALWAYS
accompany the boiler, even if it is sold to another
owner or transferred to another user or to another
installation.
If you damage or lose this manual, order a repla-
cement immediately from your local rTechnical
Assistance Centre.
aDo not allow children or infirm persons to operate
this r RTQ boiler unsupervised.
a Do not operate any electrical devices or equipment,
including switches or domestic appliances, etc., if
you can smell fuel or fumes. If you detect any suspi-
cious smells:
- Ventilate the room by opening all doors and win-
dows.
- Close the fuel shut-off cock.
- Report the fault immediately to the rTechnical
Assistance Service or a professionally qualified
heating engineer.
aDo not touch the boiler while barefoot or wet.
aNever clean or service the boiler without first
disconnecting it from the mains electricity supply
by turning the main power switch and the control
panel switch OFF.
aDo not tamper with or adjust the safety or control
devices without prior authorisation and instruc-
tions from the boiler’s manufacturer.
aNever pull, disconnect, or twist the electrical
cables coming from the boiler even if it is discon-
nected from the mains electricity supply.
aDo not obstruct or restrict the vents in the room
where the boiler is installed. Adequate ventilation
is essential for correct combustion.
aDo not expose the boiler to the elements. Do not
install the boiler outdoors. It is not designed to
work outdoors and is not fitted with the necessary
automatic anti-frost systems to do so.
aDo not switch the boiler off if outdoor temperature
drops below ZERO (risk of freezing).
aDo not store containers of flammable substances
in the room where the boiler is installed.
aDo not dispose of packaging material into the
environment, or leave it within the reach of chil-
dren, since it can become a potential hazard.
Dispose of packaging material in compliance
with applicable legislation.
The operation of any appliance that uses fuel, electrical power and water demands that a number of fundamental safety
precautions be respected.

PRODUCT DESCRIPTION
rRTQ steel boilers are high efficiency boilers with
horizontal, flame reversal combustion chambers and
concentrically arranged flue gas pipes. They are desi-
gned for central heating and, when used in conjunction
with a suitable storage cylinder, for domestic hot water
production too.
Because they operate at low pressure, they provide a
gradual heating action without thermal shock.
The most important technical features of these boilers are:
– The combustion chamber and heat exchange system
are specially designed and shaped to achieve the
best possible volume ratio.
– Only top quality materials are used to ensure a long
working life.
Stainless steel turbulators inside the flue gas pipes esta-
blish an ideal pressure inside the combustion chamber
and an ideal flue gas temperature. Evenly distributed
thermal load optimises the efficiency of the boiler-burner
system.
The boiler body is thoroughly insulated with a layer of
high density glass wool.
The boiler’s front door and the flue gas box can be ope-
ned completely to facilitate the inspection, maintenance
and cleaning of internal parts and to speed up servicing
in general.
The front door can open in either direction, even without
removing the burner.

CONTROL PANELS
b When a CL/M control panel is installed, the boiler return (cold) line must be equipped with a sensor socket.
The r control panels that can be used with r RTQ steel boilers are listed below. These control panels cater for
all the needs of the heating system and of all the devices installed in it.

RECOMMENDED BURNERS
The burners recommended to obtain the best possible performance from r RTQ boilers are:
GENERAL
(*) Long head REQUIRED.
(**) Burner with 2 discs supplied. Remove the tube from inside the burner and install the two discs as instructed in the
burner’s own manual.
b 1 - Long heads and burner plates are required for the correct installation and coupling of the burners.
2 - If a two stage burner is installed, 1st stage heat input must not be less than 70% of total heat input. With liquid
fuel burners equipped with 2 nozzles, it is therefore important to choose the correct first stage nozzle

b If these plates or any other means of clearly identifying the product are defaced, removed or lost, proper installation
and servicing may be rendered difficult.
– Serial number plate
This is located on the boiler body and specifies
the serial number, model, and furnace power.
– Data plate
This lists the technical specifications and perfor-
mance of the product.
It comes inside the documentation envelope. On
completion of the installation you MUST apply it in
a clearly visible position at the top of one of the
side panels.
If you damage or lose this label, order a repla-
cement immediately from r’s Technical
Assistance Service.
The boilers are identified by two plates:
PRODUCT IDENTIFICATION
b Blast tubes must not exceed the specified lengths by more than 20%.
aDo not re-use old burners if their blast tube lengths are below those specified in the table.
BURNER PLATE
rRTQ boilers have burner plates with holes arranged to accept the recommended burners. The following table
shows the dimensions of the holes.
IMPORTANT
If you are installing a new boiler but re-using an old bur-
ner, always perform the following checks.
- Make sure that the performance of the old burner is
adequate for the requirements of the boiler.
- Make sure that the length and diameter of the burner’s
blast tube are as specified in the following table.
b When you finish installing the burner in the boiler,
fill the gap between the burner’s blast tube and the
refractory material in the door with the ceramic insu-
lation (A) supplied with the boiler.
