CHAPTER 10
WATER
Qualities of Water to Use
Water quality will vary from one location to another. Different qualities of water can have a
damaging effect on your HEATMOR™ furnace, pumps, and plumbing components. Please
observe the following guidelines for best results.
• Do not add water from ponds or off roofs.
• Do not add water exceeding 50 parts per million (ppm) in chlorides.
• Do not add water over 27 grains hardness - mix this water 50/50 with softened water.
• Do not add water exceeding 50 ppm silica content.
• Do not add water from shallow wells.
• Do not add water from a well that has recently been “shocked” with chlorine.
Water Level Maintenance
You can verify the water level of your HEATMOR™ by checking the fullness of the bladder.
The water level gauge (“add water” weight) inside the front door of the HEATMOR™ should
be up near the bladder, not down near the shelf. An even better method of gauging the
fullness of the bladder is to reach up through the bladder cover plate and feel the bladder.
The bladder should still have wrinkles in it when the water temperature is 180 degrees
Fahrenheit. If the lling procedures were done correctly, the bladder would have been
the last thing topped up after the water jacket of your HEATMOR™. Refer to “Filling your
Furnace Initially” for further details or contact your local dealer.
Removal/Replacement of System Water
If a sediment faucet was installed at the back of furnace, it may be used for draining
purposes. If you have a sediment faucet installed on the main manifold in the house, that
also can be used to drain the HEATMOR™. The drained contents of the HEATMOR™
must be discharged to an area or place where they will not damage property or
create an environmental hazard. If you are draining the system because of total
system shutdown in cold weather, remember to also drain the supply and return
lines to prevent freeze-up.
To rell your HEATMOR™, refer to “Filling your Furnace Initially.” It is important to add
water treatment to the HEATMOR™ once you have relled your HEATMOR™. For further
information on replacing the water in your furnace, contact your local dealer.
