This design complies with the current edition of ANSI Z21.10.3 as an automatic circulating tank type water heater and automatic storage water heater. Detailed installation diagrams are found in this manual. These diagrams will serve to provide the installer with a reference for the materials and methods of piping necessary. -
Page 5: Features
FEATURES IMPORTANT IT IS REQUIRED THAT A QUALIFIED SERVICE TECHNICIAN PERFORM THE INITIAL FIRING OF THE HEATER. A CHECKLIST AND SERVICE INFORMATION section are included at the rear of this manual. By using this checklist the user may be able to make minor operational adjustments and save himself unnecessary service calls. -
Page 6: High Limit Switch (E.c.o.)
HIGH LIMIT SWITCH (E.C.O.) The top immersion well of the upper probe also contains the high limit (energy cutoff) sensor. The high limit switch interrupts the main burner gas flow should the water temperature reach approximately 199°F/93°C. Should the high limit switch activate, it must be reset by cycling power to the unit. -
Page 7: Hot Return Recirculation Pump
HOT RETURN RECIRCULATION PUMP The hot return recirculation pump circulates the hot water through the hot water line to eliminate delays at plumbing fixtures, see Figure 5. FIGURE 5 DRAIN VALVE The drain valve is used to drain the water from the tank assembly and plumbing manifold assembly, see Figure 6. -
Page 8: Air Hose
AIR HOSE The air hose is used to provide a flexible air path from the blower to the burner assembly. It is held in place with two standard hose clamps, see Figure 10. FIGURE 10 FLUE ADAPTER The flue adapter is made of a flat metal plate with an exhaust adapter to mate with the exhaust elbow. -
Page 9: Low Gas Pressure Switch
LOW GAS PRESSURE SWITCH The Low Gas Pressure Switch is a single pole, normally open pressure switch that will close its contacts when a rising pressure of 6.2 inches (1.53 kPa) w.c. is encountered. The contacts will open when the pressure falls below the fixed set point of 6.2 inches of w.c. -
Page 10: Low Water Cutoff Board And Probe
LOW WATER CUTOFF BOARD AND PROBE The Low Water Cutoff Board and Probe monitors the water level to confirm the tank is completely full. This function is very important when the unit is first filled with water and when complete loss of power is encountered during freezing temperatures (in case the unit drains while using the anti-freeze kit), see Figure 20. -
Page 11: Cabinet Assembly
CABINET ASSEMBLY CABINET PANELS There are five panels that comprise the cabinet assembly. The ends of the cabinet allow access to all controls and plumbing. Please confirm all joints are attached correctly and sealed to prevent water leakage inside the cabinet, see Figure 26. FIGURE 26 ADDITIONAL CONTROLS GAS VALVE... -
