ÜKYP/YP Automatic Fuel Loading, Central System Heating Boiler Usage and Maintenance Manual
ELECTRICAL INSTALLATION INSTRUCTIONS
ÜNMAK ÜKYP/YP series boilers are fed with 230 Volt mains voltage. A regulator should be used where
the mains voltage is less than or greater than ten percent.
The control panel must be connected to a wall panel with suitable grounding equipment, the distance
between the boiler panel and this wall panel should not exceed 50 cm.
For each boiler room, a separate grounding installation should be made from the column installation.
Grounding installation:
a) 0.5 m2, 2 mm. thick copper plate,
b) 0.5 m2, 3 mm. thick galvanized sheet (hot dipped) or
c) It should be done with solid copper rod electrodes.
Copper rod electrodes must be at least 1.5 m tall with a diameter of Ø16 mm or a length of at least
1.25 m with a diameter of Ø 20 mm, and the grounding resistance of the rod electrodes must remain
below the limits of 20 Q. (Neutral-Ground voltage ≤3V)
In all three cases, copper electrodes or plates should be connected to the natural gas installation by
soldering or welding using at least 16 mm2 stranded copper cable and conductive shoe. Copper
electrodes or plates should be placed in the ground completely, the conductor remaining on the
ground must be connected to the pipe casing and the boiler room main table.
THIS PRODUCT MUST BE CONNECTED TO A SAFE GROUND LINE!
Have your electrical connection made by ÜNMAK Authorized Services.
The boiler must not be installed in closed and living spaces.
