A
Condensing boiler or furnace, floor-mounted type
B
Condensing boiler or furnace, wall-mounted type
C
JM neutralizing tube floor-mounted (or multiple tubes piped in
parallel)
D
JM neutralizing tube wall-mounted (or multiple tubes piped in
parallel)
E
Y-fitting, 3/4: PVC minimum – locate a minimum of 2 inches above
the neutralizing tube and so the overflow line is below the bottom of
appliances condensate drain connection (item L)
F
Appliance condensate trap/condensate drain connection
H
Overflow drain line (terminate so flow from line is easily seen)
J
Floor drain, sump or condensate pump reservoir
L
Bottom of appliance condensate drain connection – all condensate
piping and components must be below this level
M
Bottom of JM neutralizer tube outlet connection
N
Terminate the overflow line above the drain location so any flow
from the line is easily visible

Inspect frequently
Installer — Instruct the building owner to
frequently inspect the JM neutralizer and
all condensate connections. The owner
must notify a qualified technician if any
problems are noticed.
Maintenance
4
OUTDOOR INSTALLATIONS — provide and install
electric heat tape
on the condensate drain lines
and around the JM tube to prevent possibility
of neutralizer tube damage or line blockage due
to freezing. Failure to comply with the following
guidelines could result in severe personal injury,
death or substantial property damage.
Recharge as required
When pH tube or tank outlet falls below
5PH. Local codes may have different
requirement, check with local authority.
Replacement parts
Contact your local wholesaler or manu-
facturer’s representative for replacement
parts.

Piping Options
Overflow by-pass piping
See Figure 4 and Figure 5 for installation with a y-fitting for
an overflow by-pass line.
Locate the overflow discharge so flow can be easily seen.
Instruct
the owner to notify the service technician immediately if
flow through the overflow line is frequent or steady.
Make sure the installation complies with all local code
requirements.
Piping for multiple boilers/furnaces
Use separate neutralizer for common vent drain.
As stated on page 2, do not connect a flue pipe condensate
line to the to the same neutralizer as used for a boiler/furnace
unless the boiler/furnace is individually vented, the vent will
not allow rain water to enter the flue pipe, and no other
appliance is connected to the same neutralizer tube.
