Acidic Condensate pH Treatment System

How much reside condensate will my equipment develop?
Hot water heaters / Boilers / Furnaces / Economizers
Multiple Boiler Common Flue drains: 33.3% of total BTU input of connected equipment.
Example: (3) Boilers @ 100,000 BTU Input would need a pH treatment kit rated @ 100,000
BTU for the stack drain and a ow rate of .725 to .798 depending on eciency.
Consider the following when choosing a neutralizer for less maintenance during operation
of your heating equipment.
1. Your location in relation to weather (Very Cold, Cold, Moderately Cold)
2. System Design (Process, Radiate, Snow Melt, Heating, etc.)
3. Yearly Operating Hours
4. pH level out of heating equipment (3.2 to 4.0 is normal)
5. If pH out of the heating equipment is below 3.2 pH contact the factory for sizing.
6. Abnormally low pH out of the equipment condensate drain can be caused by the following:
A. Improper Combustion
B. Contaminated Combustion Air
C. High Sulfur Content in Gas Supply
D. pH below 2.0 is considered hazardous waste by EPA. Contact JJM Technical
Service at 413-427-3373 or 413-527-1893
JJM® highly recommends operating your heating equipment for 24-48
hours prior to connecting a neutralizer so as to ush out dirt, grease, and
oils from connected piping and the heater. is is also the best time to check
the heater condensate pH level for sizing your neutralizer.

!WARNING
JJM® neutralizers are sized by BTU input to establish a ow rating.
Job site conditions will determine neutralizer design. See GPH chart below.

Inspect frequently
Installer — Instruct the building owner to frequently inspect the CBM neutrazlier and all condensate connections. e owner must
notify a qualied technician if any problems are noticed.
Replacement parts
Contact JJM® Boiler Works, your local wholesaler or manufacturer’s representative for replacement parts and rell kit.

!DANGER Install all electrical wiring in accordance with the National
Electrical Code and local requirements.
Indicates a condition or hazard which will cause severe
personal injury, death or major property damage.
WARNING
Indicates a condition or hazard which may cause severe
personal injury, death or major property damage.
CAUTION
Indicates a condition or hazard which will or can cause
minor personal injury or property damage.
NOTICE
Indicates special attention is needed, but not directly related
to potential injury or property damage.
NOTICE
is unit when installed must be electrically grounded in

Read before proceeding
Failure to comply with these guidelines could result
in severe personal injury, death or substantial
property damage.

theCBM-227andtrapswithtapwater.NEVERoperatewith
tubesorP-trapsdry.
Application restrictions
• Condensing boilers, furnaces, hot water heaters and ue pipe
condensate drains.
• DO NOT exhaust ue gases through CBM tubes, they are not
rated for boiler or furnace ue gases. Operating tubes as ex-
haust vents can cause injury or death from carbon monoxide.
• Gas traps must be installed between the boiler, ue drains,
and furnace condensate outlet and the inlet of all JM tubes.
• JM tubes must be installed below system P-traps, boiler,
furnace, and breaching condensate drains.
• e use of Ferris and Copper piping on the neutralizer inlet or
out is not permitted. e use of CPVC, PVC, PP Tubing, and
Stainless Steel piping is the only material that shall be used.
Combined piping options
Flue pipe condensate drains
• Boiler/furnace condensate drain and ue condensate drain
can be commonly piped to a neutralizer tube. Also, the ue
pipe must be terminated so rain water cannot enter the ue
pipe.
Replace tubes regularly
• Tubes should be replaced when pH level moves below5.0.
e pH should be checked regularly (at least twice during the
rst year of operation) to determine the required recharging
schedule.
• At minimum a recharge should take place at least once a year.
• Use only JJM® pH Power Pellets®, DO NOT USE LIMESTONE
CHIPS.
What is pH?
e pH measurement of a uid is an indicator of the acidity or
alkalinity. Neutral uids have pH of 7.0. Acid uids have pH below
7. And alkaline uids have pH above 7 (up to 14). e pH can be
easily measured using digital pocket pH probe.
Condensate pH from condensing boilers and furnaces is typically
around 3.2 - 4.0. e condensate pH needs to be increased (made
more neutral) to prevent possible damage to cast iron soil pipe,
ABS pipe, septic tanks, plants, wastewater treatment plants and
other materials handling waste water.
CBM condensate pH treatment tubes
increase pH (reduce acidity).
CBM re side condensate neutralizing tubes are designed to raise
the pH level of the condensate discharged by high-eciency
boilers, warm air furnaces and hot water heaters.
Each increase of 1.0 in pH is a 10-times decrease in acidity. e
pH of condensate is increased by approximately 1.0 to 3.0 aer
passing through neutralizing tubes.
Applying CBM neutralizing tubes
Condensate can be collected from ue ways and boiler/furnace
condensate trap outlets. See WARNING section at le for guide-
lines on application.
Match neutralizing tubes to boiler/furnace ratings. Consider us-
ing the next larter size neutralizing tube for boiler systems with
domestic hot water heating.
Locate the neutralizing tube below the condensate connection
and slightly above the oor drain or inlet to a condensate pump
reservoir (if used).
Follow the guidelines in this manual, the boiler/furnace manual
and all applicable local codes when installing, using and main-
taining CBM condensate neutralizing tubes.
Installation sequence
1. Before installing boiler or furnace, determine if a mounting pad will
be needed to elevate the boiler or furnace so that the condensate
connection will be above bottom of the CBM OUTLET. See Figure2
or Figure3. Provide a mounting pad for the CBM tube if needed to
obtain the proper elevation relative to a condensate pump reservoir
(when used — see Figure3).
2. Connect PVC piping from appliance or breaching drains to P-traps
and then from P-trap outlets to either one of the two CBM tube inlets.
3. Connect the CBM tube outlet to house drain or condensate pump.
4. Use Teon tape on all threaded plastic ttings.
5. NOTE — Always consult the local authority regarding any require-
ments concerning ue gas condensate handling codes.

CBM tube for inspection and service. — Secure pipe or tubing in
place. — Protect with a shield if necessary if routed through trac
areas.
R Use hose clamps at all connections when using plastic tubing.
S Condensate drain termination at oor drain (or condensate pump
reservoir inlet) — secure in place with clamps. — Follow instruc-
tions for condensate pump.
T Elevate the CBM tube on a structural base if necessary for the
outlet to be raised.
U Route condensate discharge line from to appropriate drain loca-
tion.
