24 Installing the System Piping
3.2.1 Condensate Neutralizer Kit
WARNING
To prevent serious injury or death:
●
DO NOT allow exhaust flue gases to vent
through the neutralizer. Inhalation of
flue gases can result in carbon monoxide
poisoning.
●
ALWAYS install the neutralizer so its inlet and
discharge are closer to the floor than the
condensate drain.
●
ALWAYS install an overflow bypass connection
between the appliance and the neutralizer to
prevent the backflow of condensate into the
appliance.
●
DO NOT connect more than one appliance to
the neutralizer.
If option ‘b’ (p. 23) is selected as the disposal
option, the Navien condensate neutralizer kit is
recommended. The condensate from the appliance
flows through the neutralizing media and increases
the pH of the condensate. An increased pH prevents
corrosion of the installation’s drainage system and
the public sewer system.
Installation
●
The inlet has a center connection port and the
outlet has an offset connection.
●
Install the neutralizer on the wall or the floor and
secure it using the brackets supplied with the kit.
●
If the neutralizer is installed horizontally, rotate
the neutralizer to position the outlet at the
highest point (Figure 1).
●
If the neutralizer is mounted vertically, ensure that
the outlet is higher than the inlet (Figure 2).
●
Ensure that the condensate runs freely to the
drain.
●
Ensure all connections are made to prevent
the backflow of condensate. Use corrosion
resistant piping and secure all piping to prevent
movement.
Note
Do not install condensate piping in
areas where the temperature drops
below freezing point. Protect piping in
high pedestrian areas from damage and
vibration.
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 GPH of drainage for
each boiler 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
1
/
4
in per foot.
NOTICE
To prevent property damage, do not allow
condensate line to freeze or become obstructed
or condensate can flow from the drain.
5. Fill the condensate trap by pouring water into
the boiler’s exhaust vent until water flows
through the condensate drain.
NOTICE
To prevent property damage, do not allow
condensate line to freeze or become obstructed
or condensate can flow from the drain.
