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.

2-3-3 Installing flue (For Roof Terminals)
①
For Roof Terminals
1. In the case of a pitched roof 25-50 degrees, position the lest
tile to replace/flash over existing roof tilling. Make an aperture
in the roof suitable for the lower tube of the roof terminal and
ensure the integrity of the roof cover is maintained. The
adjustable plastic collar can either be positioned. on the lead
tile or the lower tube of the roof terminal prior to the final
positioning of the vertical flue through the tile Check the collar
is correctly located to suit required roof pitch (either 25˚ to 38˚ or
37˚ to 50˚) From inside the roof adjust the to vertical position and
secure to the roof structure with the clamp supplied.
2. For flat roof installations the aluminum flashing must be
incorporated into the roof covering and the appropriate aperture
aperture made in the roof decking. The vertical flue is lowered
onto the flashing. (A mastic seal may be necessary). From inside
the roof, structure with the clamp supplied
IMPORTANT : If the boiler is not fitted immediately after the flue
System, temporary precautions must be taken to prevent rain entry
into the room of installation, Any precautionary measures must
be removed prior to commissioning the boiler.
② Flue Dimensions

2-4-1 Standard piping
※
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.

2-4-2 Gas / Water connection
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.

4. Installing neutralization device of condensate
1) 1Check the connection of the neutralization box and the hose from main heat exchanger.
2) Check the connection of the Air pressure s/w and make-up water hose.
3) Check the level of neutralizer whether it is enough or not. If need, fill it in the tank.
4) Connect the drain hose to the drain hole on the bottom of neutralization tank.
-. Caution!: Link the drain hose to the sewer of house which is made up with PVC or Stainless steel.
4) Check the water level and fill the water to safety level of neutralization tank by opening make-up water valve.
-. Caution !: Before the start of operation after installation or long stop, open and close the air pulling valve
on the top of main heat exchanger and keep the safety water level of the neutralization tank.
※ Warning! : When shortage of water in tank, it may cause the danger due to the return of the exhaust gas.
-. Keep and install the appliance horizontally in order to drain well the condensate.
