Water Treatment Policy
Water Treatment Policy
To qualify for warranty water must be tested a minimum of once per year and water treatment
added when necessary.
To test the water open the boiler drain located at the bottom of the rear of the furnace until the water
runs clear. Fill one of the test bottles provided to you by your dealer and mail to our testing lab using
the mailing carton and label provided with the bottle. Make sure to note if the furnace water contains
any antifreeze or additional chemicals. If any adjustments need to be made to the water you will
receive a report outlining what must be done. 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 be added at a 1:200 ratio when initially firing 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 pH level is 9 – 10. 5.
Recommended nitrite levels are 600-1000 ppm.
What Water Treatment Does
What Water Treatment Does
The water treatment used in outdoor furnaces are nitrate based water treatments which act as
oxygen scavengers, neutralize harmful bacteria and harmful minerals and elements in your water to
reduce scaling and corrosion in your furnace and plumbing system.
Test Parameters and What They Mean
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 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 9-10.5) 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
