Before Starting Installation - Dunkirk ARTESIAN 220 Installation And Operating Instructions Manual

IV. BEFORE STARTING INSTALLATION
1) Make sure that the planned installation is
in accordance with all local codes.
2) Be certain the domestic water supply to the tank
has physical and chemical characteristics that
fall within the limits shown in Table 7. Where
questions exist as to the composition of the
water on the job, a qualified water treatment
expert should be consulted.
IMPORTANT
Water with characteristics outside the limits shown in Table 7 may severely shorten the life of the heat
exchanger due to corrosion. Damage to the heat exchanger is not covered under warranty. Do not use the
water heater if the water is excessively hard. Lime and other deposits will occur and reduce the unit's
effectiveness.
3) Read and understand all installation requirements in this manual.
4) When adding a water heater to an existing system, the additional water content of the tank must be
considered. Verify that the expansion tank sizing is correct.
IV Locating The Artesian
WARNING
Failure to properly support a water heater tank installation could result in property damage or personal injury.
1) Table 2 shows the weights of all water heaters filled with water. The location chosen for the water heater
must be capable of supporting both the weight of the water heater(s) and the weight of the boiler(s).
2) Locate the water heater in an area where a leak in the tank, or the adjacent piping, or an open temperature
and pressure relief valve will not damage the surrounding `structure. If the area around the desired tank
location is highly susceptible to water damage, install the water heater in a pan with a drain.
3) The water heater may be located some distance from the boiler provided the piping system is designed to
provide the minimum boiler water flow called for in Table 1. Also, the further the water heater is from the
boiler, the longer the response time of the boiler will be to a call for heat from the water heater zone. If long
runs exist between the boiler and the water heater, it is advisable to insulate the piping.
Table 7: Water Chemistry Requirements
Water used in the water heater must have
characteristics falling within the following limits:
Characteristic
pH
Dissolved Chlorine (PPM)
No measurable amounts of chlorine containing
compounds, such as cuprous chloride, are permitted.
