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 boiler drain located at the bottom of the rear
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 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.
•
Place bottle in the tube. Attach top part of the label to
sample bottle and bottom part to the outside of mailing
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 HeatMaster
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.
Add the water treatment through the fill pipe located at
the top of the furnace when initially filling 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 firing the furnace and 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 flush
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.
