3.4 Electrical Installation
Your device operates with 220V 50 Hz electric
supply.
Prefer 3*1,5mm2 cable for electrical installation.
On the other hand, 2A fuse is needed on electric
wiring that is control the boiler electric supply.
You must be sure correction of phase and neural
connection ways.
Ground connection absolutely has to be
connected to boiler.
Do not definitely use water or natural gas line for
grounding. In case of using, do not forget that
your device will be out of warranty for damages
that can occur.
3.5 Pipe Line
- Pipe line must be made suitably to legal
regulations.
- You must be sure that all connection points of
pipeline are leak proof.
- Pipe line must be durable to heat, condensing
water and mechanical stress.
- Pipe installation must be made as 1⁰ inclined
through the boiler.
- In case of combustion air is taken from
environment, maximum pipe length is 20m.
90⁰bend correspond with 2 meter pipe and
45⁰bend correspond with 1,5m pipe.
- Do not forget that extra connection accessories
that will be used for line will also create
resistance and will reduce allowed total pipe
length distance.
- Your boiler must be together with an internal
pipe gas temperature sensor. In case of any
temperature exceed, it stops the system for
security.
- In case of combustion air is taken from
environment, necessary environment ventilation
must be suitable to boiler capacity.
- The operating temperature of boiler is between
-15, and + 60 ⁰C. Environment temperature must
be between these values.
- There is freezing prevention function in your
boiler. When environment temperature
decreases less than 5 degree, this function start
to operate separately from operating
programme. Boiler heating function becomes
active and operates until boiler return water
temperature reaches to set temperature then it
stops.
- Your device is produced as concentric pipe but
according to demand it can be supplied with
double pipe or later it can be converted to double
pipe with necessary accessories.
