Read before proceeding
Failure to comply with these guidelines could result
in severe personal injury, death or substantial
property damage.
Neutralizer and lines must be wet
•
Before operating the boiler , furnace or hot water heater, fill
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 flue pipe
condensate drains.
• DO NOT exhaust flue gases through CBM tubes, they are not
rated for boiler or furnace flue gases. Operating tubes as ex-
haust vents can cause injury or death from carbon monoxide.
• Gas traps must be installed between the boiler, flue 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.
• The use of Ferris and Copper piping on the neutralizer inlet or
out is not permitted. The 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 flue condensate drain
can be commonly piped to a neutralizer tube. Also, the flue
pipe must be terminated so rain water cannot enter the flue
pipe.
Replace tubes regularly
• Tubes should be replaced when pH level moves below 5.0.
The pH should be checked regularly (at least twice during the
first 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?
The pH measurement of a fluid is an indicator of the acidity or
alkalinity. Neutral fluids have pH of 7.0. Acid fluids have pH below
7. And alkaline fluids have pH above 7 (up to 14). The pH can be
easily measured using digital pocket pH probe.
Condensate pH from condensing boilers and furnaces is typically
around 3.2 - 4.0. The 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 fire side condensate neutralizing tubes are designed to raise
the pH level of the condensate discharged by high-efficiency
boilers, warm air furnaces and hot water heaters.
Each increase of 1.0 in pH is a 10-times decrease in acidity. The
pH of condensate is increased by approximately 1.0 to 3.0 after
passing through neutralizing tubes.
Applying CBM neutralizing tubes
Condensate can be collected from flue ways and boiler/furnace
condensate trap outlets. See WARNING section at left 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 floor 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 Teflon tape on all threaded plastic fittings.
5. NOTE
— Always consult the local authority regarding any require-
ments concerning flue gas condensate handling codes.
