1IMPORTANT

qThis booklet contains operating and maintenance instructions and must be handed to the user.

Please read all the instructions and warnings carefully as they provide important advice for safe

installation and operation. This booklet should be kept in a safe place for future reference.

qThe boiler must be installed by qualified personnel according to current safety regulations and

following the Manufacterer’s instructions. Improper installation may cause damage or injury. The

Manufacterer cannot be held responsible in such case.

qFirst unpack the boiler and check that it is complete. In case of doubt, do not use the boiler and

return it to the Supplier. No packaging (including wooden crates , nails, staples, plastic bags,

polystyrene foam, etc.) must be left where children can play with as it may constitute a hazard.

qThis boiler must only be used for the purpose for which it was designed. It must be never be used

for other purposes as this would create a hazard. The Manufacturer cannot be held liable for

damage caused by improper or unreasonable use.

qBefore cleaning or servicing the boiler, disconnect from the power mains by operating the switch

on the system or the relevant on-off devices.

qDo not obstruct the intake or outlet grilles.

qIf the device does not work or malfunctions, disactivate it but do not attempt to repair it yourself.

You must contact a qualified service operator. Repairs must only be carried out by a service

centre authorized by the Manufacturer, using original spares. Failure to do this may well affect the

safety of the device.To guarantee complete efficiency and correct operation, it is very important to

follow the Manufacturer’s instructions. Schedule maintenance must be carried out by a qualified

service operator.

qIf the boiler is taken out of service, all parts liable to cause a future hazard must be disposed of

properly.

qIf the boiler is sold or transferred to another owner, or if you move premises and leave the boiler

behind, always make sure that the booklet stays with the boiler so that it can be consulted by the

new owner and/or installer.

For boiler’s mounting and location:

MUST COMPLY WITH THE RELEVANT LOCAL SAFETY STANDARDS

2BUILDING CHARACTERISTICS

The SIMPLEX boilers are pressurized combustion heat exchangers made of steel with inversion flame

type and successive turn in the tube system.

The high speed of the fumes inside the tubes and the high turbolence provoked with the new

TURBOLATORS IN STAINLESS STEEL AISI 430, favours the heating exchange, decreases of the

consumption, increasing the combustion yeld that reachs an efficiency over 90%.

The jacket consists of elegant panels in steel painted with epoxy powder paint, and is totally insulated

with rock wool in order to give it high an heat insulation characteristics.

The power losses on the smoke side are so limited as the allow a wide range of choice for operation

with gas oil-fire burners with forced air.

The front door hinge-mounted it’s insulated inside with ceramic fiber to be resistant high temperature

and take the functions:

§fumes reversal chamber

§furnace and tube system inspection and cleaning

§burner support

The control panel is complete with all the instruments necessary to optimise the control and the

correct operation of the boiler.

The boiler body is made of iron and completely is welded with procedure mag (metal-arc active gas),

arc welding in active gas atmosphere with electrode fuse.

In order to ensure maximum quality and reliability over time, all the boilers are subjected to testing

under severe conditions during all the phases of the production.

The shelves are checked and tested hydraulically at 4,5 bar.

The maximum working pressure is 3 bar.

3INSTALLATION

The boiler must be installed by a qualified person. The size and features of the room must comply with

the relevant safety standards. All regulations involving the safety of technical installation must be

complied with.

Before connecting the heating system advise to carried out a tubes washing to prevent that impurity

put in jeopardy the boiler corrected functioning.

Flue gas be discharged through pipes with a diameter no less than that of the hood and connected to

a stack of suitable capacity. The stack must be of a suitable size and height to ensure minimum draft

as per specification and thermally insulated as prescribed.

The connection of the burner to the fuel piping must be carried out by qualified personnel following the

instructions with the burner

The electric connecting must carried out stable and safe. It’s more important to carry out the electric

connecting to the feeding line under the laws in force.

Before electric connecting it must be checked an efficient earthing wiring because this is a basic safety

requirement.

Not use the water-pipes and the gas-pipes for earthing.

Besides verify the wiring suitable for the equipment and burner maximum power adsorption.

3.1 BURNER MATCHING

For installation of the burner, the electrical connections and the

necessary settings, consult the burner instruction manual.

Ascertain that the correct type of burner has been

chosen for the boiler, checking the technical specifications of both.

The burner blast tube must be sized as shown in the picture here

beside.

3.2 OPERATING

Starting up the boiler

Before starting up the boiler, check that:

♦the system is full of water and that the pressure on the gauge does not exceed the rated value of

1,5÷2 bar

♦the stack was built in compliance with the current regulations, perfectly free and there is not air

infiltration

♦the connection between boiler and stack is perfectly tight-proof

♦the flanges or fittings are perfectly sealed and the power supply voltage corresponds to that

required for the boiler

♦the burner rated values (power supply and nozzle flow) are compatible with the boiler and that

there is no air infiltration in the fuel oil pipes

♦all air has been relieved from the system

♦pump delivery and lift suitable for heating system delivery

Operating

The SIMPLEX boiler is only designed to supply hot water for room heating. After pressing the ON-OFF

button to turn on the boiler and set the required temperature on the thermostat, the burner starts and

after the temperature set on the anti-condensation low point thermostat (TM= 55°C), the heating

circulating pump starts.

When the preset temperature is reached, the burner stop until new heat is requested.

N.B. If the boiler exceeds 100 °C, the safety thermostat cuts in and stops the burner. To

resume operation, unscrew the thermostat cap and press RESET. If this occur again, ask for the

service by a qualified personnel.

4MAINTENANCE

The boiler must be cleaned at least once every season. Turn on the main power switch andrelease

the on/off button. Remove the burner and plate together with the lining. Open the front door, the rear

stack and the cast iron plate covering the rear element.

Clean the horizontal flue gas conduits, the combustion chamber. The fumes range cleaning it’s more

important, only millimetresof soot increase the flue gas outlet temperature at least 30°C decreasing

one percentage point of thermal efficiency.

Water properties

The chemical and physical properties of the water in the circuit and refill water are the basic elements

for safe trouble-free operation of the system. It’s known that bad water quality causes inconveniences

to the entire system, the most common and serious inconvenience being the formation of scale on the

heat exchange areas. Due to their considerably low heat conductivity, scale deposits, although of a

small thickness, create insulation of the wall that are not cooled by the circulating water and are thus

subjected to overheating, and this provokes uneven expansion or localized thermal shocks.

Water treatment is required when:

water system are very extensive

water available has a high hardness index

for any reason whatsoever, the system needs to be partially or fully emptied and then filled up again

Water properties for filling and topping up are:

Appearance clear

Total hardness max 20 °F

Free oxygen max 0.005 mg/l

Organic substances max 0.5 mg/l

pH min. 8.5
