Instructions for the installer

3.10 CONDENSATE DRAIN

The condensate drain into the sewer must be:
- built to avoid gaseous combustion products from leaking out into the
environment or the sewer (trap).
- sized and built to allow liquid discharge to runoff correctly, preventing
any leaks (gradient of 3%).
- installed to avoid the liquid contained in it from freezing, under the
envisioned operating conditions.
- can be easily inspected from the relative trap
- mixed with household wastewater, for example, (washing machine
and dish washer drains etc.) with a mainly alkaline pH so as to form
a buffer solution to send it into the sewers.
The condensate must not be left to stagnate in the combustion product
drainage system (for this very reason the evacuation pipe must be set
up at an inclination of at least 30 mm/m, running towards the drain)
except for any liquid head, in the drain trap of the combustion product
evacuation system (which must be filled after installation and at a
minimum height with all of the fans operating at maximum speed of
at least 25 mm) - see figure.

* Minimum safety trap enforced by regulation
** Minimum head with boiler operating at maximum power.
If you do not want to or are able to create a platform, it is possible to
install the boiler on the floor and set up the trap at a depth of 100 mm.
It is forbidden to drain the condensate towards rain pipes, given the
risk of ice and degradation of materials normally used to build the rain
pipes themselves.
The drain fitting must be visible.
Given the degree of acidity of the condensate (pH between 3 and 5)
suitable plastic materials must be used to build the drain pipes.
The condensate drain pipe outlet is set up towards the connection
side of the flue box manifold, removing the pre-sectioned part on the
cover panel.
The recommended material for use must be PE (polyethylene) or PPI
(polypropylene).

Before igniting the generator, fill the trap through
