Navien G 002212 Series User manual

INTRODUCTION
DIMENSIONS AND INCLUDED PARTS
NOTE: Connections to the appliance and neutralizer kit must be installed to ensure that no condensate
backow can occur. Connect corrosion resistant piping and secure it to the oor or wall to prevent
movement and/or damage.
Please follow these installation instructions carefully in order to avoid a safety hazard and/or injury.
WARNING
• “Risk of damage to appliance”. The neutralizer kit inlet and discharge must be at a lower
elevation than the condensate drain from appliance.
• Do NOT allow exhaust ue gases to vent through the neutralizer kit. All condensate drains
must have a trap to prevent ue gas leakage. Flue gas leakage can cause injury or death from
carbon monoxide.
• Connection to the appliance and neutralizer kit must be installed to ensure that no
condensate backow can occur into the appliance.
• Do not connect more than ONE appliance to the neutralizer kit.
Condensate Neutralizer
Installation Instructions
PREPARE FOR INSTALLATION
FLOW
Condensate Neutralizer Kit Includes:
• One (1) corrosion-resistant neutralizer housing with 4” ll/access openings (0.26 gallon / 1 liter volume)
with 3/4”- 14 FNPT threaded INLET and OUTLET connections
• One (1) 1/2” FNPT x 1/2” PVC Socket Weld Adapter
• Two (2) 3/4” MNPT x 1/2” PVC Socket Weld Adapters
• One (1) Wall Mounting Bracket with Screws
OPERATION
• The appliance condensate will ow through the neutralizing media, raising the pH of the condensate to a level
that will help prevent corrosion of the domestic drain and the public sewer system.

• Open the capsule and ensure media is level inside. If necessary, the orientation of the neutralizer can be reversed
by removing the wall bracket and moving it to the other side of the lid (see Figure 1 on next page).
• The INLET has a top connection port and the OUTLET has a side connection. Mount the neutralizer unit on the
wall by securing it with the provided bracket (see INCLUDED PARTS section above).

Installation Instructions
Rev. 5/22
• Mount as per the installation diagram below (see Figure 1). Check that the neutralizer is upright in the proper
position as shown in the above diagram. The neutralizer should be installed after the trap. Ensure that the
condensate will ow freely from the appliance drain into the neutralizer then to an approved drain by applying
sucient slope to the drain pipe.
• Access to the discharge is necessary for proper maintenance in order to check the eectiveness of the
neutralizing media using pH test strips.
• If there is no gravity drain available, install a condensate removal pump designed for use on condensing
boilers and water heaters. The condensate pump must be equipped withan overow switch to prevent operation
of the appliance due to failure.
• The oat should be down during normal operation (see Figure 2). If ow in the neutralizer becomes restricted, the
oat will rise and lock in position, indicating that the media should be cleaned or replaced (see gure 3). After
replacing the media, reset the oat by pressing it back to the down position.
• Monitor the cleanliness, level of the neutralization media, and pH level in the neutralizer monthly. Remove any
precipitate coating or debris found to prevent blockages. Check the pH level at the outlet of the neutralizing
kit using a suitable pH test strip paper or an electronic pH meter for precise measurement. The neutralizing
media should be replaced when the pH level drops below the minimum level of the local water authority, when
the oat rises (see Figure 3 above), or after one (1) year, whichever comes rst. For replacement media, contact
your local Navien distributor.
• The unit is warranted against defects in materials and workmanship for ONE YEAR. The warranty does
NOT cover issues that result from misuse, improper installation, and/or failure to replace the media.
