ABSOLUTELY NO FIRE IN THE FIREBOX WHEN PERFORMING THIS PROCEDURE.
DO NOT PERFORM THIS PROCEDURE WHEN UNIT WATER TEMPERATURE IS
UNSAFE. ALWAYS WEAR PROPER PERSONAL PROTECTIVE EQUIPMENT WHEN
WORKING WITH WATER AND CHEMICALS.
Principles of Water Treatment
1. Minimize the corrosion potential of system metallurgy.
2. Keep water in the 8 to 10 pH range.
3. Acts as an oxygen scavenger.
4. Water treatment supplied with the HEATMOR™ does not give any freeze
protection.
5. With proper chemical control, longer equipment life can be achieved.
Addition of Water Treatment
When installing a completely new system, we recommend that the system rst be lled with
water only. After two or three days of operation, check that all air is out of the system, and
all connections are leak free. Once the entire system is conrmed to be leak free, add the
water treatment.
To add water treatment to the HEATMOR™ furnace, follow these steps.
1) Before adding the treatment, drain out a corresponding amount of water.
2) Remove the pop-off ball (if equipped) from the relief vent pipe.
3) Take a funnel and place it into the relief vent pipe.
4) Pour the entire contents of the water treatment chemical, as supplied, into the
HEATMOR™ furnace.
5) Top off your HEATMOR™ furnace with water, ll the bladder, and replace the
pop-off ball (if equipped). Refer to
“Filling the Bladder Initially” for details or contact your local dealer.
Water Treatment Maintenance / Result
The water in the HEATMOR™ should be chemically analyzed once per year to ensure
the proper levels of treatment are being maintained. Contact your local dealer as to where
to have your water tested. Provide the testing person with an amount of water from your
HEATMOR™, equal to approximately 20 ounces, in a clean container. The amount of
water treatment that has to be added yearly is dependent on how much fresh water you
have added to your system since the last test. Be certain to add a water treatment that is
approved by your dealer and HEATMOR™ Inc.
