Overview
Read before proceeding
Failure to comply with these guidelines could
result in severe personal injury, death or
substantial property damage.
Tank and lines must be wet
Before operating the boiler or furnace, fill the
NB tank and traps with tap water. NEVER
operate with tanks or P-Traps dry.

Application restrictions
• Flue gas condensing boilers, furnaces, hot water heaters
and flue pipe condensate drains only
• DO NOT exhaust flue gases through NB tank, is not rated
for boiler or furnace flue gases. Operating NB tanks as
exhaust vents can cause injury or death from carbon
monoxide.
• Gas traps must be installed between the boiler, vent drains,
hot water heaters and furnace condensate outlet and the
inlet of all NB tanks.
• NB tanks must be installed below sysem P-traps, boiler,
furnace, and breeching condensate drains.
Combined piping options
Flue pipe condensate drains
• Boiler/furnace condensate drain/hot water hearter and flue
condensate drain can be commonly piped to a neutralizer
tank. Also, the flue pipe must be terminated so rain water
cannot enter the flue pipe.
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 4. 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.
NB-series condensate neutralizing tanks
increase pH (reduce acidity).
NB-series commercial fire-side condensate treatment tanks are
designed to raise the pH level of the condensate discharged by
high-efficiency boilers and warm air furnaces.
Each change of 1.0 in pH is a 10-times reduction (or increase) in
concentration. The pH of condensate is increased by approximately 1.0 to 4.0 higher after passing through NB neutralizing
tanks.
Applying NB-series neutralizing tanks
Condensate can be collected from flueways and boiler/furnace/
hot water heater condensate trap outlets. See WARNING section
at left for guidelines on application.
Match neutralizing tubes to boiler/furnace ratings. Use multiple
tanks if needed to handle the load. Consider using the next larger
size neutralizing tank for boiler systems with domestic hot water
heating.
Discharge lines may be mounted overhead.
Follow the guidelines in this manual, the boiler/furnace manual
and all applicable local codes when installing, using and maintaining NB-series Condensate pH treatment tanks.
Recharge tanks regularly
Installation sequence
• Tanks should be recharged 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.
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 NB tank OUTLET. See Figure 2.
2. Place the NB tank in position. Fill the tank to the maximum fill
line with neutralizing agent obtained from JJM® Boiler Works only.
3. Connect PVC piping from appliance or breeching drains to P-traps
and then from P-trap outlets to either one of the two NB tank inlets.
4. Connect the NB tank via the 1/2” pump outlet lines can be run
overhead or on the floor. Vinyl reinforced tubing is recommend.
5. Use Teflon tape on all threaded plastic fittings.
6. NOTE — Always consult the local authority regarding any require-
ments concerning flue gas condensate handling codes.

Maintenance Procedures
Getting the most out of your JJM® Neutralizer
Acidic wastewater neutralizers like all filtering devices need both maintenance and replacing. The average pH level of acidic wastewater produced by today’s condensing boilers, hot water heaters, furnaces, flue stack drains, and stack economizers is 3.2pH. When
using a passive Inline Tube, Tank, or Canister the range of pH modification will fall in between 5.0 and 9.5 pH.
When the pH falls below 5.0 at the outlet port of any neutralizer the active ingredient must be replaced. Media replacement schedule
will depend on several factors including Operating Hours, Efficiency, System Design, and Neutralizer Piping Scheme. The active
ingredient in the case of JJM® products is Magnesium Hydroxide Pellets. The trade name is pH Power Pellets®.
Before changing the pellets when the pH level falls below 5.0 you can get the most out of your neutralizer by first agitating the pellets.
In the case of an inline tube products try lightly tapping the outer sides of the tube with a rubber mallet several times and then check
the pH level once again at the outlet port. You may find that your pH level has risen back into the 5.0 to 9.5pH range.
When your neutralizer is a tank product with loose pellets you can simply use a wooded dowel to stir the pellets and again use
fresh tap water to flush out the tank.
If your neutralizer pellets are incased in a porous pellet bag there are three methods to agitating the pellets:
1. Remove the pellet bag or bags from the tank and using your hands move the pellets around inside the bags.
2. Using a five gallon bucket filled with fresh tap water, use step one with the bag under water.
3. Using a fresh water hose slowly pour fresh water over both sides of the pellet bag and also use method one.
If the pH level is has not risen back into the safe range of 5.0 to 9.5 pH the pellets must be replaced.
If you have our Model V-250 or V-250 Combi vertical canisters try the following method:
1. Twist off the outer canister to get access to the inner pellet cartridge and over a five gallon pail shake the Cartridge several times
to agitate the pellets.
2. Again using a five gallon pail filled with fresh tap water let the cartridge soak for five minutes under water and then drain and hand
shake the cartridge to agitate the pellets. Also clean out any sediment which may be held within the outer canister.
DURING ALL OF THE ABOVE PROCEDURES THE FOLLOWING SAFETY ITEMS MUST BE USED:
1. WEAR SAFETY GLASSES
2. WEAR RUBBER OR LATEX PROTECTIVE GLOVES
3. SHUT OFF ALL ELECTRICAL POWER TO THE HEATING UNIT OR UNITS BEFORE SERVICING YOUR
NEUTRALIZERS.
The pellets are Non-Hazardous and can be disposed of in your normal refuge.
