Then the maximum flow rate and available pump head should be used to determine if the boiler is suitable for installation without the addition of a Rinnai low loss header plumbing kit (part number 804000061). It is the responsibility of the contractor or engineer to calculate the pressure drop through the system and the required flow... -

7. If the E50C boiler is installed in a system with zone valves and the constant recirculation function is activated, then a differential pressure bypass valve or a low loss header plumbing kit is required to be installed. -

Definitions Single Heating Loop System A single heating loop system can be considered any of the following piping – arrangements: series loop, one pipe with diverter tees, or two pipe reverse return. These types of systems will have only a single room thermostat centrally located that controls the boiler. Zoned System A zoned system is a heating system that utilizes multiple zones which are individually controlled by –... -
Page 7: Calculating Zone Flow Rates
Calculating Zone Flow Rates Notice Zones should be balanced using balancing valves to ensure the correct output (flow rate) of each zone. Use the hydronic formula to calculate the flow rate for each zone. The constant 500 is based on the use of water as the heat transfer fluid in the system, where 8.33 pounds/gallon of water x 60 minutes per hour = 500. -

ATTENTION Rinnai strongly recommends the use of full port ball valve zone valves; these valves provide a lower pressure drop than a gate valve type zone valve. The lower pressure drop will allow for longer loop lengths and better flow through the zones. - Page 9 The single zone serial flow system in Drawing 1 consists of the following copper fittings and tubing and is designed to operate at 4.0 gpm flow rate at 170°F supply temperature. (Below is a list of each type of component and quantity of the components contained in drawing 1.) a.

Notice Rinnai recommends that the tee fittings for the pressure relief valve and the boiler drain are placed directly below the boiler as shown in the drawing above. These fittings then can be utilized as connection points for taking a differential pressure in the... -

Drawing 4 *Rinnai strongly recommends the use of full port ball valve type zone valves to allow for the best performance of the boiler and system. When piped as shown in the drawing above, the air handler cannot have an internal pump. -

Appendix D Example – Calculating the Equivalent Length (Alternate Method) Drawing 9 The single zone serial flow system in Drawing 9 consists of the following copper fittings and tubing and is designed to operate at 4.0 gpm flow rate at 170°F supply temperature. (Below is a list of each type of component and quantity of the components contained in drawing 9.) a. - Page 19 1) Calculate the pressure drop of the additional fittings d and e by using the C value of fittings from Table 4 and for the values of from Appendix B table 7. For this case both fittings d and e have the same C value so account for this in step 5: 2) Convert the pressure drop calculated in step 1 from psi to feet of head (1psi=2.3 feet of head)
