				Installation & Operation Manual   
					1 General Information   
					The Lochinvar SSS series indirect water heater (FIG. 1-1) is   
					designed to generate domestic hot water in conjunction with   
					a hot water boiler using forced boiler water circulation. This   
					indirect water heater consists of a 444 Stainless Steel tank in   
					which a smooth 304 stainless steel coil is located. Boiler water   
					is pumped through the coil and heats the water in the tank.   
					This tank is not intended for use in pool heating applications   
					or for heating any fluid other than water. It is also not   
					intended for use in gravity hot water heating systems.

				Installation & Operation Manual   
					2 Pre-installation   
					1. The installation must conform with the instructions   
					in this manual and all applicable local, state,   
					provincial, and national codes, laws, regulations, and   
					ordinances. Installations in Canada must conform to   
					B149.1 or B149.2 Installation Codes.   
					Locating the Tank   
					1. Figure 1-1 on page 4 shows the weights of all the tanks filled   
					with water. Make sure that the location chosen for the tank   
					is capable of supporting it.   
					2. Be certain the domestic water supply to the tank has   
					physical and chemical characteristics that fall within   
					the limits shown in Table 2A. Where questions exist   
					as to the composition of the water on the job, a   
					qualified water treatment expert should be consulted.   
					Failure to properly support the tank could   
					ƽ WARNING   
					result in property damage or personal injury.   
					2. Locate the system in a location where a leak in the tank, the   
					adjacent piping, or an open T & P valve will not damage the   
					surrounding structure. If the area around the desired tank   
					location is highly susceptible to water damage, install the   
					tank in a pan with a drain.   
					Water with characteristics outside the   
					CAUTION   
					limits shown in Table 2A may severely   
					shorten the life of the tank due to   
					corrosion. Damage to tanks in such   
					cases is not covered under warranty.   
					3. The tank may be located some distance from the boiler   
					provided the zone system is designed to provide the flow   
					called for in Table 3A - Pressure Drop Values, through   
					the coil. Also, the further the tank is from the boiler, the   
					longer the response of the boiler will be to a call from the   
					tank zone. Insulate piping between the boiler and the tank.   
					3. Read and understand all installation requirements in   
					this manual.   
					Table 2A   
					Water Chemistry Requirements   
					Recommended Clearances   
					Water used in the tank must have characteristics falling   
					within the following limits:   
					The installation location must provide adequate clearances for   
					servicing and proper operation of the water heater. A 12 inch   
					vertical clearance is recommended from the top of the water   
					heater. A zero clearance is allowed for the sides of the water   
					heater. However, boiler and servicing clearances must be figured   
					when locating the water heater.

					3 Piping   
					DHW Prioritization   
					Boiler Side Piping   
					This piping system is designed to provide direct hot water   
					priority over the other zones in the heating system. When there   
					is a Domestic Hot Water (DHW) call for heat, the Knight control   
					will shut off the boiler circulator and activate the domestic hot   
					water circulator. Once the DHW demand is satisfied, the boiler   
					circulator will be readjusted as demand requires. The circulator   
					must be large enough to move the boiler water through the coils.   
					The recommended piping for a DHW priority system is depicted   
					in FIG. 3-3 on page 8.   
					Figures 3-1 thru 3-3 show typical boiler side piping for   
					several common situations. Regardless of which system is   
					used it is imperative that the flow rates called for in Table 3A   
					on page 6 are developed through the coil. This requires   
					properly sized piping and a properly sized pump.   
					The system shown in FIG’s 3-1 thru 3-3 are described below:   
					Zone with Circulator to Aquastat   
					This system is like the circulator zone system on a straight   
					heat job except that one of the zones goes to the tank instead   
					of radiation. As on any circulator zone system check valves   
					should be installed in each zone to prevent unwanted   
					circulation through zones which are not calling for heat.   
					Figure 3-1 on page 7 illustrates typical circulator zone   
					piping.   
					Multiple Tank Connections (Boiler Side)   
					Multiple tank installations must be done in the “reverse-return”   
					manner. The reason for this is to create the same pressure drop   
					(and therefore, the same flow) through the coil of each tank.   
					The boiler manifold piping must be sized so that each coil has   
					the flow rate called for in Table 3A below. For example, if two   
					tanks are to be manifolded together, the circulator and zone   
					piping common to both tanks must be capable of moving   
					16 GPM (2 x 8 GPM), see FIG. 3-4 on page 9.   
					Zone with Valve to Aquastat   
					As with the circulator zone system, this system is just like a   
					standard heating zone system except that one of the zones is   
					connected to the tank coil as shown in FIG. 3-2. The   
					circulator must be large enough to move boiler water   
					through the coil regardless of the flow rate required through   
					the heating zones.   
					Because the pressure drop through tank coils varies from size to   
					size, it is hard to predict the flow rate that will be developed   
					through each coil when two tanks of different sizes are placed in   
					the same manifold. For this reason it is best not to mix tanks of   
					two different sizes in the same zone if their recovery is critical.

					3 Piping   
					Tank Piping with a “Temperature Limiting   
					Valve”   
					Usually, the maximum temperature of the outlet water will stay   
					near the setting of the tank control. In some cases, however, hot   
					water usage patterns can cause the outlet water temperature to   
					rise significantly above the control setting.   
					Domestic Side Piping   
					Basic Domestic Piping   
					Figure 3-5 on page 12 shows typical domestic water piping for   
					a tank. All components except the control are provided by the   
					installer. The function of the components shown are as   
					follows:   
					The temperature of water going to the fixtures may be more   
					carefully controlled through the use of a thermostatic mixing   
					valve. This device blends a controlled amount of cold water   
					with the hot water leaving the tank so that water at a more   
					a. Shut-off valves (recommended) - Use to isolate the   
					tank for servicing.   
					b. Backflow Preventer (required by some codes) - Use to   
					prevent water from backing out of the tank in the event constant temperature exits the mixing valve. Anti-scald mixing   
					that inlet water pressure drops.   
					valve piping is illustrated in FIG.’s 3-1 thru 3-3.   
					c. Expansion Tank (required when a backflow preventer is   
					used) - This expansion tank absorbs the increased   
					volume caused by heating water. If a backflow   
					preventer is installed, this expansion tank is required   
					because the increased water volume will otherwise have   
					no place to go and the T & P valve will open.   
					An anti-scald mixing valve does not   
					eliminate the risk of scalding.   
					ƽ WARNING   
					* 
					* 
					* 
					Set the tank thermostat as low as   
					practical.   
					Feel water before bathing or   
					showering.   
					Use an expansion tank designed for use on domestic   
					water systems.   
					Refer to the expansion tank   
					If anti-scald or anti-chill protection is   
					required, use devices specifically   
					designed for such service. Install   
					these devices in accordance with their   
					manufacturer’s instructions.   
					manufacturer’s literature for the proper size expansion   
					tank to use.   
					If an expansion tank is used, do not put   
					any valves between the expansion tank   
					NOTICE   
					and tank inlet.   
					Multiple Tank Domestic Water Piping   
					d. Unions (optional) - Use to disconnect the tank in the   
					unlikely event that this is necessary.   
					Figure 3-4 illustrates the recommended method of piping the   
					domestic water side of several tanks together. All tanks are   
					piped in true parallel. Total domestic pipe lengths must be the   
					same from point of tank exit to the common “T” to ensure an   
					equal draw from each tank.   
					e. Drain (required) - Used to drain the tank for   
					inspection or servicing.   
					Each tank must have its own T&P valve. It is recommended that   
					each tank be equipped with its own isolation valves, unions, and   
					drains so that one tank may be removed from the system. If   
					local codes require a backflow preventer, check with the   
					appropriate authority to find out whether one backflow   
					preventer may be used for tanks or each tank must be equipped   
					with its own backflow preventer. If each tank must have its own   
					backflow preventer, each tank must also have its own expansion   
					tank. If a common backflow preventer is permitted, an   
					expansion tank must be sized to accommodate the expansion   
					volume of all tanks.

				Installation & Operation Manual   
					3 Piping   
					(continued)   
					For proper operation of the T&P and to   
					prevent the T&P from activating due to   
					boiler water temperature, use a T&P relief   
					Domestic Water Piping for Distant Fixtures   
					NOTICE   
					NOTICE   
					In some cases the furthest fixture may be quite distant from the   
					tank. In such an installation the configuration shown in   
					FIG. 3-5 would result in an unacceptable delay before hot water   
					reaches these distant fixtures. Even if all the fixtures are   
					relatively close to the tank, the building owner may want hot   
					water at all fixtures as soon as they are opened.   
					valve with extended element.   
					The   
					recommended element length is 8 inches.   
					The Lochinvar SSS series water heaters will   
					absorb less than 200,000 Btu/hr when   
					domestic water outlet temperature is 210°F   
					and boiler water supply temperature is   
					240°F. Listed outputs are based on ASME   
					Section VIII Interpretation VIII-1-86-136.   
					Check with local codes for applicability.   
					A solution to this problem is that a pipe runs from the furthest   
					fixture on each branch back to the return of the tank. A small   
					bronze circulator is mounted in this line and is wired so as to   
					run continuously. A check valve in this line permits flow   
					towards the tank inlet only.   
					When no fixtures are drawing water, the bronze circulator   
					moves hot water from the tank to the end of the branch just   
					below the last fixture, then back to the inlet of the tank via the   
					return pipe. When a fixture is opened, hot water is already out   
					in the branch very close to the fixture and hot water appears at   
					it almost immediately. The check valve prevents cold water in   
					the tank’s inlet pipe from passing around the tank and heading   
					directly to the fixture.   
					Standard Installation   
					• 
					Install the T&P relief valve in the connection marked   
					“Relief Valve”.   
					T&P Relief Valve Discharge Piping   
					T&P relief valve discharge piping must be:   
					- made of material serviceable for a temperature of   
					250°F or greater.   
					Because hot water is always circulating in the hot water branch   
					the entire branch should be insulated to prevent excessive heat   
					loss.   
					- directed so that hot water flows away from all persons.   
					- directed to a suitable place for disposal.   
					- installed so as to allow complete draining of the T&P   
					relief valve and discharge line.   
					Temperature & Pressure (T&P) Relief Valve   
					- terminated within 12" of the floor.   
					To reduce the risk of excessive pressures and

					5 Start-up and Check-out   
					4. Make sure that each zone valve or circulator operates when,   
					and only when, its thermostat calls for heat. Let each zone   
					operate long enough to purge any remaining air from the   
					system.   
					1. Make sure the system is free of leaks and that air is   
					purged from the system.   
					Fix any leaks found before proceeding   
					CAUTION   
					further. Leakage from the boiler piping   
					can result in severe damage to the boiler.   
					5. Set the indirect water heater to the desired temperature.   
					Because hot water presents a scald hazard, it is best to set the   
					thermostat at 120°F or lower and raise it only if necessary to   
					provide adequate hot water.   
					2. Many soldering fluxes contain Zinc Chloride which can   
					cause severe corrosion damage to stainless steel. After   
					completing all domestic water connections, flush the   
					indirect water heater thoroughly before leaving the   
					installation. This is particularly important if the indirect   
					water heater will be unused for an extended period of   
					time after installation. Flush the indirect water heater by   
					drawing at least three times its volume from the tank.   
					6. Re-enable the burner and allow the boiler to operate. Make   
					sure that the boiler shuts down when the indirect water   
					heater is satisfied.   
					3. Make sure that all electrical connections are made   
					correctly and that no exposed high voltage wiring is   
					present.   
					6 Maintenance   
					The Lochinvar SSS series indirect water heater is an extremely simple device and as such requires very little maintenance. There   
					are, however, several items which should be checked out on an annual or as needed basis to ensure a reliable supply of hot water:   
					* 
					The indirect water heater depends upon the boiler for a   
					source of heat and is therefore only as reliable as the boiler.   
					Make sure that the boiler is maintained in accordance with   
					the boiler manufacturer’s instructions.   
					* 
					On an annual basis, remove the black cover over the   
					hand hole and make sure the hand hole cover is   
					leak-tight.   
					* 
					* 
					Make sure that the rest of the boiler and domestic   
					water piping is free of leaks.   
					* 
					If a water treatment system is required to keep the water   
					chemistry within the parameters shown in Table 2A (see   
					Section 2 - Pre-Installation), make sure that this system is   
					properly maintained.   
					If there is an oil lubricated circulator in the system,   
					make sure it is lubricated as called for by the   
					circulator manufacturer.
