Installation and usage tips


Boiler heaters with thermostats are equipped with thermostats with STB protection, i.e. a non-return thermal fuse.
The fuse will operate after exceeding a certain temperature and the heater will stop heating. In this case, remove the knob by gently prying it, then press the fuse button next to the thermostat axis with a thin screwdriver.

Not all our products have a seal in the form of an o-ring as standard.
The solid installer is equipped with Teflon tape or tow (carded yarn) with a thread sealing paste.
The previously mentioned materials can also be purchased in almost any installation store.
