Condensate Outlet Connection - Ferroli Optimax 25 C Instructions For Installation, Use And Maintenance Manual

Connection to collective fl ues or single fl ues with natural draught
If you are then going to connect the Optimax 25 C boiler to a collective flue or a single flue with natural
draught, the flue must be expressly designed by professionally qualified technical personnel in conformity
with the standards and rules in force.
In particular, flues must have the following characteristics:
• Be sized according to the method of calculation stated in the standard
• Be airtight to the products of combustion, resistant to the fumes and heat and waterproof for the
condensate
• Have a circular or square cross-section (some hydraulically equivalent sections are permissible), with
a vertical progression and with no constrictions
• Have the flue conveying the hot fumes adequately distanced or isolated from combustible mate-
rials
• Be connected to just one unit per floor, for at most 6 units in all (8 if there is a compensation duct or
opening)
• Have no mechanical suction devices in the main ducts
• Be at a lower pressure, all along their length, under conditions of stationary operation
• Have at their base a collection chamber for solid materials or condensation of at least 0.5 m, equipped
with a metal door with an airtight closure.

2.7 Condensate outlet connection

The boiler is equipped with an internal air-trap to drain off the conden-
sate. Fit the inspection coupling A and the hose B, pushing it on for
approximately 3 cm and securing it with a clamp.
Fill the air-trap with approximately 0.5 ltrs of water and connect the hose
to the waste system, or soakaway.
