1.1 INSTALLATION SPECIFICATIONS OF RTT CAST IRON

BOILERS

This installation manual is for certied and authorised installers

and technical assistance personnel, operating domestically and

abroad. The manual has the purpose that the cast iron boiler is

installed correctly.

9 Make sure that the room where the installation will occur

is suitable for the minimum dimensions set out in the bur-

ner's instruction booklet and that the base on which the

boiler will sit is adequate for its weight and dimensions.

9 It is the responsibility of the installers to ensure the neces-

sary safety conditions during all the assembly and installa-

tion phases; if the conditions are not optimal, adopt the ne-

cessary corrective measures before starting the installation.

9 The installation of the ON range cast iron boilers requires at

least 2 people, pay particular attention to the handling of

heavy components, in order to prevent the risk of injury to

people and damage to objects.

9 The boiler is supplied with all its components and some

installation equipment, the following assembly material is

included: silicon, applicator, brush, sealant for couplings,

Blakite, gloves and face mask

9 Carefully read the manual before installation, for any clari-

cations do not hesitate to contact the technicians of the

manufacturer or the retailer.

9 Be careful not to damage the painted components (body

and boiler cladding) when handling, assembling and when

connecting the burner and the ue gas pipe. Make sure that

all the technicians are aware of these warnings.

Thanking you for taking the time needed to read these in-

structions, we hope your installation goes well and we would

like to remind you that a good installation will ensure the boiler

continues to run well over time.

• If you do not have one, create a base suitable for the weight

and size of the boiler it needs to support, respecting the

provisions and the dimensions indicated in the technical

manual.

• Fix the rear element on the boiler base to the ground using

dowels.

• Clean the grooved prole of the ue gas seal of the rear ele-

ment with a brush or with a cloth and then ll it with silicon.

• Insert the insulating cord already ready in the groove as

shown in the illustration and x it with the silicon that was

applied previously.

• (Repeat the operations for the successive elements).

• Clean the housings of the ttings of the rear element and

put the sealing coating on them (in orange) to improve their

seal.

• (Repeat the same operations for all the intermediate ele-

ments and the front element).

• Clean the surfaces of the couplings and apply the sealant

coating on the surfaces that come into contact with the rear

element to enhance the seal. Insert the coupling into the

element.

• (Repeat the operations for the all the couplings).

• Pass the tie-rods (M10 x 200) into the assembly holes of the

rear element and the intermediate element.

• Using an M10 wrench, tighten the nuts at the ends of the

pins to bring the elements closer and in contact.

• Depending on the boiler model (number of intermediate

elements), the assembly operations described will have to

be repeated for each of the unnumbered intermediate ele-

ments.

• The last two intermediate elements are always marked by

the numbers 3, 2. Once the assembly of the unnumbered

intermediate elements has been completed, mount the

intermediate element with the number 3, followed by the

intermediate element 2. For clarication of the assembly

sequence, see the gure

9 The intermediate element with the number 3 that contains

the thermostat housing should necessarily be assembled in

the third row from the front side.

The front element, marked with the number 1, is the last one to

be tted.

Insert the M16 locking tie-rods into the relative holes and tighten

the nuts at the ends to bring the elements closer to each other.

Tightening torque: 7 kg·m

• The ue gas pipe is xed using 2 threaded bars, washers

and nuts.

• The size of the ue gas pipe varies according to the following

table:

Boiler model Flue gas pipe dimensions

RTT 163 180

RTT 195 180

RTT 227 180

RTT 259 250

RTT 291 250

RTT 323 250

RTT 355 250

Assembling the anges:

• Apply the silicon to the at ange seal and stick it to the

mounting surface of the rear element. Insert the assem-

bly screws into the at ange and with these x the ange

to the boiler outlet (top side) tightening the lock nuts. The

Thermix ange should be connected to the lower side of the

rear element (return) as shown in the gure.

• Once the anges have been assembled, pass over the outer

surfaces of all the boiler elements with Blakite stucco.

• Fill the body of the boiler with water and carry out a hydrau-

lic seal test lasting 10 minutes at a pressure lower than 9 bar.

• Check the gas seal along the lines of contact between the

elements.This check can be carried out with a mobile light

or a projector. Light the inside of the boiler and observe it

from the outside. Apply Blakite to the points that let light

lter through to the outside.

• Installation of the retarder turbulators:

RTT 291 2 large 2 medium 2 small

RTT 323 2 large 2 medium 2 small

RTT 355 2 large 2 medium 2 small

• The front edge of the turbulators should not exceed the mid

point of the front element during positioning.

• The number of turbulators per boiler should be as indicated

in the table.

• The door of the boiler burner should be tted after the tur-

bulators have been installed.

• Insert the 4 tie-rods of the hinges of the door in the relative

holes on the front element. Connect the door of the burner

to the tie-rods inserted in the hinges, t the washers and

tighten the lock nuts until the pressure of the insulating cord

can be felt on the prole of the front element.

• Insert 2 screws M10 x 75 in the top part of the hinges taking

into account the door the side should open from.

• The burner door should be raised slightly during opening

and closing (bringing the door attachments above the hei-

ght of the hinges)

• The installation of the casing will begin after nishing the

assembly of the body.

• First of all, x the casing's assembly bracket to the front and

rear feet of the boiler.

• Connect each assembly bracket of the casing to the foot

of the boiler inserting two M8 x 25 screws in the holes of

the foot, as shown in the gure. Then tighten the screws,

locking them with nuts and washers.

• After xing the four brackets, proceed with tting the top

shelves.

• For the assembly of the two shelves, use the holes in the

front element and on the rear element of the boiler body, as

shown in the gure. As xing devices use the assembly pins

of the elements (slacken and tighten the nuts locking the

pins in the elements).

• After installing the brackets and the assembly shelves of the

shell, proceed with applying the insulation on the cast iron

body.

• The insulation of the body should be shaped to create the

housing for the thermostat. Use a 2 point stainless steel wire

to connect the insulation to the boiler body in such a way

that it is stable.

• Join the side panels to the pins on the brackets of the feet

and screw them to the top shelves with M8x20 screws as

shown in the gure.

• After installing the side walls, connect the control panel on

the top front wall of the casing.

• Insert the thermocouples (sensors) of the control panel

(thermostat, safety thermostat, thermometer) in the slots of

the panel.

• Rest the two support brackets on the top panel, with the

side with more holes facing upwards and lining up the ho-

les of the bottom side of the bracket with those of the cover

panel.

• Fix each bracket with three self-tapping screws 4.2x9.5 (not

supplied).

• Remove the cover of the electrical panel.

• Place the base of the control panel on the support brackets,

matching up the holes, then use six self-tapping screws

(supplied with the electrical panel) to secure it.

• After inserting the ends of the sensors, secure them so they

do not come out, then put back the cover of the control pa-

nel on the base.

• Put the oil supplied in the hole of the thermostat so as to

improve the sensitivity of the sensors.

• Fit the top panel into the slots of the casing by inserting the

four pins into the corresponding holes on the side panels.

•

• After tting the top and side panels of the casing, proceed

to install the rear insulating panel.

• The rear cover panel is composed of two parts that should

be xed with screws to the side panels.

• The assembly is nished with the installation of the rear pa-

nel cover.

• Once the assembly of the body, the control unit and the ca-

sing is nished, the boiler is ready for the installation of the

burner and the connections to the system and to the ue

gas pipe.

• The installation of the burner and the connections to the

system and the ue gas pipe should be carried out by an

authorised technician, in conformity with the regulations

and specications contained in the use and maintenance

manual.
