Part 1: Operational Manual for USA/Canada

The use of economic and ecologic combustibles, the sweet warm of natural fire, the sweet

fragrance of the wood of our forests are the qualities that make indispensable wood fired cookers

in every house.

Your choice fell upon a Rizzoli cooker, result of a tradition started in 1 12 when Carlo Rizzoli began

the production of wood fired cookers with the typical style of the valley in the dolomites. Year after

year Rizzoli continued to refine its cookers using even more advanced technologies, but without

losing contact with the elegance, the beauty and the functionality of the original product.

1. NSTRUCT ONS

1.1 GENERAL NSTRUCT ONS

For the perfect working of Rizzoli cookers it is necessary the correct placing and connection to the

chimney and to the heating system if it is necessary. Before the connection of the device it is

necessary to contact a local chimney sweeper. The installation usually ends with the lighting of the

cooker and the verify of the correct working.

It is necessary to use well dried and good quality wood: it is also necessary to sweep the chimney

and the cooker regularly.

e recommend to read carefully the instructions in this booklet before starting to use the device.

Keep this booklet because it could be useful in case of necessity. Talking about the working and

the installation of Rizzoli cookers and thermal cookers, all the European/USA/Canadian laws,

national and local laws and rules must be respected.

1.2 SAFETY NSTRUCT ONS

• Respect all the safety distances during the installation of the device.

• The grids and the ventilation holes of the device must not be obstructed during the installation

or the use of the device.

• Extracting fans, if working in the same room where the device is installed, might cause problems

when a correct ventilation is not guaranteed.

• hen using the cooker, some parts of the device may be very hot, keep attention not to lean

and not to touch by hand hot parts (frame, plate and doors).

• hen you cook and generally when you use the cooker you must not wear flammable dresses.

• Keep more attention in presence of children.

• Do not place on the device flammable or explosive materials, in particular curtains or do not

place near flammable chemicals and aerosol cans.

• The fire door must always be closed except for lighting operations, fire feeding operations and

during the maintenance operations.

• Check regularly the fume-circuit and, the chimney connection and the chimney itself. At least

every six months of normal use contact an experienced technician for checking and cleaning the

device.

• The plate must be cleaned regularly according to necessities after every use and make regularly

the specific maintenance.

• Before you go away for a long time, be sure that the fire is terminated.

• The first lightings of the cooker and the first seasonal lightings must be done with temperate fire

in order to prevent possible breakings of the internal parts.

• After a long period in which you do not use the cooker, check carefully that obstructions are not

present and that the cooker works regularly.

• Use only original or authorized spare parts.

• Do not make any unauthorized modification.

1.3 RECOMMENDED COMBUST BLES

ood fired cookers L - S Range and thermal wood fired cookers LT - ST Range are built to use

wood for burning. e recommend to use good quality wood, dry, seasoned and split. Using good

quality wood is warranty of good heating power and avoid the forming of carbon residuals and

soot. To avoid dissipation of energy and eventual deforming and damaging processes you must

not use excessive combustible (see paragraph 7.1).

1.4 OTHER COMBUST BLES

The use of pre-compressed trunks and coal is not allowed, because the strong heating produced

may damage the internal refractors, the wood-carrying grill, the oven and in general all the parts

directly exposed to fire. Other combustibles and refuses, for example plastic, enamelled or treated

wood or carton must not be burned. Using this materials cause serious damage not only to your

health and environment but also to wood fired cooker and chimney.

The cooker must not be used as incinerator. It is recommended to use only the suggested solid

seasoned dry wood and not liquid fuel.

2. NSTALLAT ON

2.1 GENERAL NOTES

ood fired cookers and thermal cookers are easy to install; anyway you must take some cares to

avoid damages due to unskillfulness. Before the installation, we recommend to verify the

necessary space, the safety distances, the correct predisposition of the chimney and the possibility

to make the necessary connections. Do not drag the device, move it keeping it lifted from the

floor. The device must not be moved making effort on the handrail or on the handles.

2.2 SAFETY D STANCES

Be sure that the cookers and the thermal cookers that have to be framed have the minimum

safety distances to flammable or high temperatures sensible materials (see paragraph 7.2 and

safety label page 10 in Part 2 Installation Instruction). Rizzoli also produces isolated spacers to

reduce distances. The device is very heavy and must be placed on floor that can support its load

capacity. Follow local codes.

2.3 CH MNEY

Chimney has a main importance for a correct working. ood fired cookers and thermal cookers

are built to insure the maximum efficiency, anyway the performances of the cooker are deeply

influenced by the chimney. If the chimney has defects or does not match the building laws, it is not

insured the correct working of the device. To build the chimney you must use suitable materials,

made to work with high temperatures and according to fireproof laws: it is not important the kind

of material, on condition that it is right and that the chimney is isolated.

Picture 3 - Components of the chimney. A= cooker or thermal cooker, B= conjunction, C= flue, D= chimney,

E= reflow zone

2.4 D MENS ONS AND CORRECT FORMS OF CH MNEY

Chimney must be dimensioned in a correct way according to the type of device it is connected

with, minding the environmental and general conditions of the place in which it is placed. The

section of the chimney must permit the flow of the fumes produced by the cooker or thermal

cooker without difficulties, but it must not be too big otherwise the chimney will experience

problems in heating itself and this may generate problems like weak draught and condensation. In

table 1 it is indicated the recommended diameter for the flue according to the model of device

and to the height of the chimney (H). The height of the chimney must be enough to insure the

draught necessary to the chosen model. Bigger is the height of the chimney, bigger is the draught;

if the chimney is lower than 4 m (13,2’), the correct working of the cooker is not insured. The

chimney must not have tortuous parts, horizontal parts or counterslope parts; the number of

bends must be reduced to minimum. In picture 4 you can see some examples of good and bad

chimney connection.

2.5 CH MNEY FLUE

The flue must be well isolated and circular if possible. The flue must not have defects, narrowings

or losses. All the inspection doors must be closed and well sealed. The connection of other devices

to the same chimney is not allowed.

2.6 CH MNEY POT

The chimney pot must have an exit section doubled than the one of the chimney, in order to make

easier the exit of the smoke. The chimney pot must be enough tall to lean out over the reflow

zone generated by the roof: if you are not sure about this contact experienced technicians. If you

are in a windy place, it might be necessary to install windproof devices.

The chimney should extend at least 3 feet above the roof surface it penetrates and 2 feet higher

than any roofline or other obstacle within a horizontal distance of 10 feet.

2.7 STOVE P PES CONNECT ON

The connection of the device to the flue must be as short as possible and must not have horizontal

or not much inclined parts. The counterslope parts are forbidden and must be absolutely avoided.

Near the conjunction, flammable materials must not be present. The conjunction must not go

inside the flue. To increase the safety of the conjunction, we suggest to install a washer on the

wall being sure that the connection between the washer and the chimney is walled and well

sealed. Also all the connection must be fixed and sealed. Connections through wall, ceiling and

floor ( see page 4 Part 2 Installation instruction).

2.8 FLUE OUTLET POS T ON

ood fired cookers and thermal cookers are predisposed to have flue outlets in different positions

(up, back, sides). Before connecting the device to the chimney you must be sure that all the

outlets you will not use are well closed. Eventually, you can make modifications using the devices

given together with the device.

Picture 6 - Multiflue cooker/thermal cooker, predisposition of the correct flue outlet.

2.9 CORRECT CONNECT ON TO THE CH MNEY

If the conduct of the chimney starts from a lower floor than the connection point of the device, it

may be necessary to close the conduct under the connection pipe with fireproof materials. If you

have the chimney behind or up, you have to use the connector with bayonet coupling. This must

be inserted and turned so that it can remain blocked. This connector has a tolerance of about 1 cm

(0,39”) to make the installation easier. The tolerance is available according to a single direction

which depends on the orientation of the connector (see picture 7).

Picture 7 - Tolerance for flue outlet on the top and back. The tolerance depends on the orientation of the connector.

The connection with the chimney must be always well fixed and sealed, it must not have

narrowing and must not decrease the usable section of the chimney (see picture 8). If near the

cooker there is flammable material or high temperatures sensible, the connection must be

isolated and the safety distances must be strictly observed.

NO NO NO YES

2.10 A R NTAKE

The standard installation of the wood fired cooker and thermal cooker considers that the

comburent air is taken from the room where the device is installed through the air intake of the

device located in the plinth. In this case, in the room must be always ensured the recycle of fresh

air, in particular if the room is small and window and door frames are hermetic. The correct flow

of air in the room must be ensured also in presence of other combustion based devices, aspiring

hoods, chimneys and vent-holes. The air intake in the room must have a minimum surface of 80

cm2. On demand, Rizzoli can give specific valves which can allow the automatic opening of the air

intake only when it is necessary for the correct working of the device in order to warrant a

maximum depression of 4 Pa in the place of installation. The wood fired cookers and thermal

cookers can also be connected so that the comburent air comes directly from outside. In this way,

for the device it is not necessary another air intake in the room of installation. To make this it is

necessary to prepare a conduct connected directly with the external part of the house and make a

direct connection with the air intake of the device. The air intake of the cooker is located inside

the woodbox in correspondence of the combustion chamber. For the connection, we suggest to

use a flexible pipe.

cooker/thermal cooker.

A B C

Picture 10 - Possible connections of the air intake of the cooker/thermal cooker.

A= External air intake not connected, B= External air intake on the floor, C=External air intake on the wall.

To make the connection easier we suggest to make the external air intake on the floor in

correspondence with the internal part of the plinth, or on the wall through the rear part of the

device (see table 2 and picture 11). Are also possible other solutions for the connection but they

must be decided together with Rizzoli.

WARN NG! Aspiring hoods or extracting air fans in the room may generate

problems to the device if there is not a suited air intake or in case of air intake sub-

dimensioned.
