WATER TREATMENT AND TESTING POLICY WATER TREATMENT AND TESTING POLICY ELABORATED 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: 1. Locate your water sample bottle, mailing carton and mailing label provided to you by your dealer. 2. 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 in to and let cool before collecting sample. 3. Fill one of the test bottles at least 1/2 to 2/3 full. 4. 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. 5. Attach top part of label to sample bottle and bottom part to outside of mailing tube. Place bottle in tube. 6. 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. If any adjustments need to be made to the water you will receive a report outlining what must be done. 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 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 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 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 much sooner and create glycolic acid. HeatMaster SS January 2014 2 WATER TREATMENT AND TESTING POLICY Elaborated…… When initially filling the furnace every year add 1 gallon of boiler treatment for every 200 gallons of water and at test your water every year after that to ensure that the water is at the optimal condition (9 to 10.5 for pH and 600-1000 for nitrite). Boiler Treatment may have to be added or subtracted depending on the current qualities of the water being filled in to the furnace. If adjustments have to be made we are asking that customers mail another sample to the lab (again at only the cost of mailing) to verify the chemical make up of their water is optimal and that they have made the necessary adjustments. Most times the adjustments will be very easily done. The recommended operating range ensures optimal water and that the furnace lasts as long as possible. What Boiler Treatment does….. Boiler treatment should help protect your furnace and plumbing system from corrosion, scale and sludge when maintained properly by maintaining critical elements in the water. The water treatment we have chosen also contains a corrosion inhibitor that vaporizes and forms a protective barrier on the metal in the water jacket and installation system, essentially coating the metal and reflecting and/or neutralizing the harmful properties in the water that can cause corrosion or pinholes in the steel. The difference between the “Good stuff” and the “Cheap stuff” We know that there are many nitrite based water treatments being offered for outdoor furnaces and they will say they are all the same but the truth is they are not. Some generic “boiler” treatments sold can actually cause damage to your system or produce results not intended. The water treatment we have chosen is backed by 17 years of industry knowledge to make it a complete water treatment custom designed for your outdoor furnace and plumbing system. There is a lot more that goes in to a water treatment than nitrites and pH balancer. Our treatment has 5 active ingredients designed to keep the system good for many years. Many others have only 2 or 3. Not only that but when you use our water treatment you get support from Heatmaster ss and full support from our team and lab at Certified Labs. We’ve tested many different water treatments and none have shown to provide the full protection of our water treatment.
