2-3-1 FLUE

The provision for satisfactory flue termination must be installed in accordance with local regulations.

The appliance must be installed so that the flue terminal is exposed to outdoor air.

The terminal must not discharge into another room or space such as an outhouse or lean-to. It is important that the

position of the terminal allows a free passage of air across it at all times. The terminal should be located with due

regard for the damage or discoloration that might occur on buildings in the vicinity,

it must also be located in a place not likely to cause nuisance. In cold or humidity weather water vapor may condense

on leaving the flue terminal The effect of such “steaming” must be considered. If the terminal is less than 1 meter

above a balcony, above ground or above a flat roof to which people has access, then a suitable stainless steel terminal

guard must be fitted. The minimum acceptable spacing from the terminal to obstructions and ventilation openings

are specified in Fig. X.

WarningThe exhaust gas duct must not be contact with or close to inflammable material and must not pass through building

structures or walls made of inflammable material. When replacing an old appliance, the flue system must be changed.

2-4-1 Standard pipework

※ Caution on piping

This boiler is equipped with the pressure controller of water-inlet to protect

the body and each valves from the instantaneous high-water-pressure

when or closing the water valves.

This pressure controller of water-inlet works under 2.5kgf/㎠ of inlet water

pipe pressure. Therefore, if over it, should install the pressure reducing

valve for inlet water pipe additionally.

If over pressure of inlet water, it may cause bursting pipes of house or

boiler inside and stopping hot water from boiler.

1. Gas connection 1). Make sure, using the labels on the packaging and the data plate on the appliance itself, that the boiler is in the correct

country and that the gas category for which the boiler was designed corresponds to one of the categories available in the

country where it will be used.

2). The gas supply piping must be created and measured out in compliance with specific legal requirements and in accordance

with the maximum power of the boiler; you should also make sure that the shut-off valve is the right size and that it is

connected correctly.

3). Check that the supplied gas corresponds to the type of gas for which the boiler was designed

(see the data plate located on the appliance itself).

It is also important to check that the pressure of the gas (methane or LPG) you will be using to feed the boiler is suitable,

because if it is insufficient the power may be reduced, causing inconvenience for the user.

2. Water connection 1). The illustration shows the connections for the water and gas attachments of the boiler. See valves configuration

2). Check that the maximum water mains pressure does not exceed 3bar; if it does, a pressure reducing valve must be

installed.

3). For measuring of the pipes and of the heating bodies in the heating system, the residual head value should be calculated

as a function of the requested flow rate, in accordance with the valves shown in the circulation pump graph

3. Drain connection 1). Extend the hose from the safety valve and connect the drain hole.

※ Caution ; Do not store any wettable things under the boiler or near the drain hole.
