WATER TREATMENT AND TESTING
Water Treatment Policy
To qualify for warranty, water must be tested at 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 furnace drain located in the side pump
cabinet of the furnace for 10-15 seconds or until the
water runs clear. CAUTION: Water is hot! Use extreme
care when pouring into a bucket, and let cool before
collecting a 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 the serial number of your furnace. Make
sure to note if the furnace water contains any antifreeze
or additional chemicals.
Attach top part of the label to sample bottle and
bottom part to the outside of mailing tube. Place bottle
in the 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 HeatMasterSS.
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.
Add the water treatment through the ll pipe located at
the top of the furnace when initially lling the furnace with
water or after testing, if needed. Ensure that all drains are
closed. It is recommended that water treatment is added
at a 1:200 ratio when initially ring the furnace and 1:300
after that. 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, in
excess minerals can cause many problems in hydronic
systems including scaling and corrosion.
pH
pH is a 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
and ush your furnace system.
It is always suggested to use 100% virgin glycol instead
of recycled glycol as it will break down much sooner and
create glycolic acid.
