Title: Gold Termet Plus Stove Condensate Issue: Need Drain Pipe & Pump Solution for 3L/8H

the plumber installed the stove, when choosing, he did not say anything about the need to run a pipe to the drain, I had no idea about it.
the stove is mounted on the wall next to hanging kitchen cabinets, the sewage drainage is about 3 meters from the stove, and about 15 cm above the ground, so the pipe would have to go up slightly.
about 3 liters of water are condensed during 8 hours.

How to solve this problem - I ask before the service technician comes and for his solution.
You will probably need to mount a pump to pump this water through a pipe in the floor horizontally
the plumber says that this is how it should be and I have to hold a bubble on the counter.
advise something.

In my life, I would not buy a furnace decorated with a standing water tank.

all condensates condense the water because it is their advantage (such heat recovery), you have to look for a sewage system with an entrance below the boiler drain, otherwise you will need a condensate pump, i.e. additional costs (a good condensing boiler with a good setting condenses up to 30 liters a day, so your plumber does not he has no idea about it when he tells you to put a bubble)
