WATER TREATMENT AND TESTING

Water Treatment Policy

To qualify for warranty, water must be tested a minimum
of once per year and water treatment added when
necessary.
To take a water sample:
Locate your water sample bottle, mailing carton and
mailing label provided to you by your dealer.
Open the boiler drain located at the bottom of the
rear of the furnace for 10-15 seconds or until the water
runs clear. CAUTION: Water is hot! Use extreme care
or a bucket to run water into and let cool before
collecting sample.
Fill one of the test bottles at least 1/2 to 2/3 full.
Fill out the mailing label provided with the test bottle
completely, including your email address, the model
number and serial number of your furnace. Make sure
to note if the furnace water contains any antifreeze or
additional chemicals.
Attach top part of label to sample bottle and bottom
part to outside of mailing tube. Place bottle in tube.
Mail to our testing lab. Results can take up to 4 weeks
to receive and up to 8 weeks if no email address is on
hand at Heat aster .
SS
You will receive a water test report outlining what must
be done (if anything). If any action is necessary, take
another sample and mail it to our test lab again to
verify the recommended changes have been made.
water or after testing, if needed. Ensure that all drains are
closed. It is recommended that water treatment is added
accordingly based on the water test results. Additional
treatment may have to be added for water with more
severe properties or for systems with more chemically
demanding requirements.
Recommended operating levels are as
follows:
Conductivity: 100 – 4000 ppm
pH: 8.5 – 10. 5
Nitrates: no less than 730 ppm
Test Parameters and What They Mean
Conductivity
Conductivity is a measurement of minerals in your
furnace water. While it is common to have minerals in
water, excess minerals can cause many problems in
hydronic systems including scaling and corrosion.
pH
pH is measurement of alkalinity (hard or soft water). For
outdoor furnace water and the water treatment used in
outdoor furnaces it is better to have your water a little
harder than softer (recommended pH range is 8.5-10) as
the active ingredients in the water treatment neutralize
harder water easier than softer water
Nitrates
Nitrates tested for are a measurement of how much
water treatment is in the water. Nitrates measured are
active units of water treatment available to neutralize
harmful elements in your furnace water. Nitrates also act
to neutralize harmful bacteria that may build up in the
furnace water over time.
Glycol
Inhibited glycol provides anti-corrosion elements and
freeze protection for outdoor furnaces and is compatible
with Outdoor Furnace Water Treatment. Because outdoor
furnaces are open to the atmosphere systems and will
have fresh water added occasionally, oxygen is always
entering the system and will break down the glycol over
time to create glycolic acid which will harm your furnace
system. When this happens you will be required to drain
It is always suggested to use 100% virgin
glycol instead of recycled glycol as it will break down
much sooner and create glycolic acid.
