Acidic Waste WaterCondensate pH Treatment Tank

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 flow rate of .725 to .798 depending on efficiency.
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 flush out dirt, grease, and
oils from connected piping and the heater. This 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.

Read before proceeding
Always use eye protection and plastic or rubber
gloves when installing, recharging, adding water, or
cleaning the NBT-610 & 230 tanks.
Failure to comply with these guidelines could result
in severe personal injury, death or substantial
property damage.
Keep pH Power Pellets® and power pellet bags out
of the reach of children and animals. pH Power
Pellets® (magnesium Hydroxide) are NOT food
grade and should not be consumed by humans
or animals.
Always return the clear cover lockdown bolts and
nuts in place and tighten for child safety.
DO NOT exhaust ue gases through tanks,
they are not rated for boiler or furnace ue gases.
Operating NBT tanks as exhaust vents can cause
injury or death from carbon monoxide.
Gas traps must be installed between the boiler, vent
drains, and furnace condensate outlet and the inlet
of all NBT tanks.
Neutralizer and lines must be wet
• Before operating the boiler, hot water heater or furnace, ll
the NBT tanks and traps with tap water. NEVER operate with
tubes or P-traps dry.
Application restrictions
• Condensing boilers, hot water heaters or furnaces, and ue
pipe condensate drains.
• NBT-610 & NBT-230 tanks must be installed below system
P-traps, boiler, furnace, and breeching 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 / NBT tanks
• Condensate drain piping options / Flue Drain, Boiler Drain,
Furnace Drain, Hot Water Heater Drains: See Figures
1,2,3,4,5,6, and 7.
• If using a separate NBT-610 & 230 tank for a common ue
pipe drain the tank should be rated at 33.3% of the total gross
BTU of all units attached to the common vent.
Replacement of the NBT-610 & NBT-230 pH
Power Pellet® Media Bags
• e media bags should be replaced when pH level at the
NBT-610 & NBT-230 outlet level falls below 5.0.
• At a minimum the media bags must be changed once a year.
• Use only JJM pH Power Pellet® media bags. DO NOTE USE
LIMESTONE OR MARBLE 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 a 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 wastewater.
NBT-610 & NBT-230 condensate pH
treatment tanks increase pH (reduce
acidity).
NBT residential/commercial ue-side condensate neutralizing
tanks are designed to raise the pH level of the condensate dis-
charged by high-eciency boilers and warm air furnaces and
hot water heaters.
Applying NBT-610 & NBT-230 neutralizing
tanks
Condensate can be collected from ueways and boiler/furnace
condensate trap outlets. See WARNING section at le for guide-
lines on application.
Match neutralizing tank to boiler, hot water heater and furnace
gross BTU input ratings.
Do not install a condensate pump unit before the NBT tanks
inlet; a condensate pump can only be installed at the outlet of a
NBT tank.
Locate the neutralizing tank outlet port below the condensate
connection and slightly above the oor drain or inlet to a con-
densate 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 NBT tanks condensate neutralizing tank.
Keep pH Power Pellets® and power pellet bags
out of the reach of children and animals. pH Power
Pellets® (magnesium Hydroxide) are NOT food
grade and should not be consumed by humans
or animals.
Always return the clear cover lockdown bolts and
nuts in place and tighten for child safety.

Overview

NBTseries Acidic Condensate pH Treatment Kits –– Installation/Operation & Maintenance
Installation
1. Remove all bolts and nuts from the clear cover.
2. Remove shipping bubble wrap and safely discard.
3. Remove “Date of installation label” and the “red warranty tag”.
4. Remove the pH Power Pellet® bags.
5. Remove porous pellet bags from plastic shipping bags before placing in the NBT tank.
Floor mounting units:
1. Place the NBT tank in a location where it will not be a foot trac hazard.
2. Use clamps on inlet & outlet piping.
Operational Flow:
1. Once the heating unit is red and acidic condensate is produced the condensate will ow from the heater condensate drain down
into the NBT tank’s inlet port. e acidic condensate enters the bottom chamber of the tank below the ow bae. e acid will now
ow up through the bae ports via gravity and slight head pressure at which point it comes in contact with the Magnesium Hydroxide
Pellet bag (pH Power Pellets®). A chemical reaction now takes place in which ions from the acid and pellets are exchanged raising
the ph level of the acid in the range of 5.0 to 9.0 pH. In this ranged the condensate can be safely be put to a waste drain via the NBT’s
outlet port and piping.

Maintenance Procedures
Revised - August, 2018
NBTseries Acidic Condensate pH Treatment Kits –– Installation/Operation & Maintenance
Getting the most out of your JJM® Neutralizer
Acidic wastewater neutralizers like all ltering devices need both maintenance and replacing. e average pH level of acidic waste-
water produced by today’s condensing boilers, hot water heaters, furnaces, ue stack drains, and stack economizers is 3.2pH. When
using a passive Inline Tube, Tank, or Canister the range of pH modication 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, Eciency, System Design, and Neutralizer Piping Scheme. e active
ingredient in the case of JJM® products is Magnesium Hydroxide Pellets. e 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 rst 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 nd 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 ush 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 ve gallon bucket lled 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 o the outer canister to get access to the inner pellet cartridge and over a ve gallon pail shake the Cartridge several times
to agitate the pellets.
2. Again using a ve gallon pail lled with fresh tap water let the cartridge soak for ve 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.
e pellets are Non-Hazardous and can be disposed of in your normal refuge.
