To connect the condensate drain:
1. Connect a drain line to the 13 mm fitting at the bottom of
the water heater.
Use only corrosion-resistant material for the drain line, such
as PVC or CPVC. Do not reduce the size of this fitting or the
drain line to less than 13 mm.
2. Place the free end of the drain line into an appropriate drain.
3. If you are using a condensate pump, ensure that the pump
allows for up to 3.78 LPH of drainage for each water heater
in the system.
4. If you are not using a condensate pump, ensure that the
drain line is pitched downward at a minimum slope of 6 mm
per 30 cm.
Water must be poured into the exhaust connection to
Note
fill the condensate trap.
28 Installing the Water Heater
3.6 Flue System
WARNING
Improper flue of the water heater can result in excessive
levels of carbon monoxide, which can lead to severe
personal injury. Flue should be performed only by a
licensed professional.
No specific ventilation is required in the room the water
heater is installed in. If it is installed in a cupboard or
compartment, no specific ventilation is required, providing the
aforementioned dimensions are observed. The requirements
and recommendations stipulated in the Regulation for Heating
Installations in Buildings (RITE) and any other applicable
legislation in this field must be observed.
3.6.1 Flue Terminal Positions
CAUTION
The terminal must be fitted with suitable protection if it
is less than 2 m from a balcony, on a flat roof or surface
that could be accessed by people.
The wall that the gas removal and air intake ducts are
fixed to must not be made of combustible or flammable
materials. The wall that the end of the duct passes
through must lead to the outside of the home. There
must be no hazardous materials or obstructions near the
duct.
If the outlet passes through a wall made of combustible
material the end terminal must be covered with at least
20 mm of incombustible material and must maintain a
distance of at least
50 mm from any flammable material.
The parts connecting the flue outlet must be correctly
joined using sealing gaskets. Ensure that there are no
leaks from any part of the removal circuit.
Switch off the water heater and wait for the pipes to cool
down before cleaning the gas removal and air intake
ducts.
The gas removal and air intake ducts must be protected
from snow accumulation.
