Indirect Water Heaters Installation Start-Up Maintenance Parts Warranty For Residential and Commercial Use WI Models The surfaces of these products contacted by potable (consumable) water contain less than 0.25% lead by weight as required by the Safe Drinking Water Act, Section 1417. This manual must only be used by a qualified installer / service technician. Read all instructions in this manual before installing. Perform steps in the given order.
Table of Contents Part 1 - General Safety Information 2 The following defined terms are used throughout this manual A. When Servicing the Water Heating System 3 to bring attention to the presence of hazards of various risk B. Heater Water 3 levels or to important product information. C. Freeze Protection 3 D. Water Temperature Adjustment 3 DANGER indicates an imminently hazardous situation which, Part 2 - Prepare the Water Heater 3 if not avoided, will result in serious personal injury or death. A.
C. Freeze Protection NOTE: If the water heater is exposed to the following, do not operate. Immediately call a qualified service technician. 1. Fire 2. Damage 3. Water Failure to follow this information could result in property damage, severe personal injury, or death. High heat sources (sources generating heat 100oF / 37oC or greater, such as stove pipes, space heaters, etc.) may damage plastic components of the water heater as well as plastic vent pipe materials.
A. Locating the Water Heater High heat sources (generating heat 100oF / 37oC or greater, such as boiler flue pipes, space heaters, etc.) may damage plastic components of the water heater as well as plastic vent pipe materials. Such damages ARE NOT covered by warranty. It is recommended to keep a minimum clearance of 8” from high heat sources.
TOP VIEW Figure 2 - Specifications and Dimensions of relative water hardness. Grains per gallon is the common and may shorten the service life of the water heater. reference used in the US water heater industry. Hardness Water that is classified as hard and very hard must be softened to expressed as mg/L or ppm may be divided by 17.1 to convert avoid water heater failure. to grains per gallon.
If the hardness of the water exceeds the maximum level of 7 grains per gallon, the water should be softened to a hardness level no lower than 5 grains per gallon. Water softened as low as 0 to 1 grain per gallon may be under-saturated with respect to calcium carbonate, resulting in water that is aggressive and corrosive. pH of Water pH is a measure of relative acidity, neutrality, or alkalinity. Dissolved minerals and gases affect water pH. The pH scale ranges from 0 to 14.
E. Temperature and Pressure Relief Valve On all models, an appropriate temperature and pressure (T&P) valve must be supplied and installed as detailed in the piping diagrams in this installation manual. Use both thread tape and pipe dope to install an NPT brass T&P relief valve for hot water storage tanks, as required by local codes but not less than valves certified as meeting the requirements for relief valves for hot water heaters (ANSI Z21.22 / CSA 4.
This water heater can deliver scalding water. Be careful whenever using hot water to avoid scalding injury. Certain appliances such as dishwashers and automatic clothes washers may require increased water temperatures. By setting the thermostat on this heater to obtain the increased water temperature required by these appliances you may create the potential for scald injury. To protect against injury, install a mixing valve in the water system.
I. Applications INDIRECT Figure 4 - Zoning with Zone Valves Figure 5 - Zoning with Circulators PIPING NOTES: The following notes are applicable to all of the piping applications demonstrated on this page. 1. Minimum pipe size should match connection size. Upsize pipe accordingly if greater flow is required. 2. A thermal expansion tank suitable for potable water must be sized and installed within this piping system between the backflow preventer and the cold water inlet. 3.
Part 4 - Heater Control and Wiring A. Control A surface mount thermostatic control has been provided for accurate temperature adjustment. B. Wiring Wiring is to be done in accordance with all applicable local and state codes. Turn off all power related to the boiler before starting any wiring procedures. It is recommended that a disconnect switch be installed between the boiler control and the water heater.
Part 5 - Start-Up and Operation 1. Fill the water heater by opening the cold water shut-off valve. Make certain the field installed drain valve is completely closed. Purge air from the system by opening a hot water outlet at a fixture in a kitchen or bathroom. When water flows freely from the outlet, the system is purged. Risk of scald injury increases as you increase water temperature.
Part 6 - Maintenance and Troubleshooting Periodic maintenance should be performed by a qualified the heater. Installer must also inform the owner that the lack service technician to ensure all equipment is operating safely of proper water heater care and maintenance may result in and efficiently. The owner should make necessary arrangements hazardous conditions.
