Raypak 2005, 1505 brochure Low Voltage Wiring Terminal

1. Low Voltage Wiring Terminal

Up front and easy to get to. Makes sensor wiring and BMS wiring simple and clean.

2. On Board Diagnostic Center Factory-mounted standard equipment. Gives relevant service feedback as well as possible solutions to clear the fault. All in plain english, no cryptic codes to decipher. The control also stores up to 16 fault codes in its history file for the service technician to review.

3. TempTracker Mod Controller

Standard equipment on the XTherm. This factory- mounted multi-function control delivers precise temperature control with selectable mode displays that are easy to access and read.

4. Combustion Air Fan

Cast aluminum, non-sparking construction. The state of the art variable-speed fan is controlled by the TempTracker Mod and works in smooth harmony with the main gas valve.

5. Dungs Gas Valve

The XTherm uses a state-of-the-art main gas valve manufactured in Germany. This precision gas valve works in perfect unison with the combustion air fan. The result is silky smooth light-offs.

6. Flow Switch

Monitors water flow and provides safe shut down if water flow drops below the minimum required.

7. Vent Pressure Switch

Monitors vent pressure and provides safe shut down if back pressure is excessive.

8. Gas Inlet

The XTherm will operate at 100% full rate with gas pressures as low as 4.0”w.c.

9. Water Outlet

10. Heater Pump

Sometimes referred to as the primary pump. This fixed speed pump keeps flow constant through the primary heat exchanger.

11. Water Inlet

The XTherm can accept 50°F continuous inlet water temperature.

12. Cold Water Run Pump

The XTherm comes factory equipped with a built in Cold Water Run system. This advanced water control system keeps the inlet water temperature to the primary heat exchanger above 120°F, regardless of the incoming water temperature. It constantly self adjusts and regulates the incoming water flow while still maintaining a constant ΔT in the heat exchanger.

13. Flue Outlet

The stainless steel flue outlet is compatible with AL29-4C. PVC or CPVC vent material may be used in conjunction with the D-32 vent option on the XTherm. Dramatically cut your installation costs by using these non-metallic vent materials.

14.Stainless Steel Secondary Heat Exchanger Recovers waste heat to boost efficiency up to 97%. The XTherm utilizes a separate high-grade stainless steel heat exchanger. This allows the corrosive combustion condensate to be collected safely without damaging the heater. There is a condensate disposal connection on the rear of the heater. The XTherm is also equipped with a condensate switch that will sense a blocked condensate drain, which protects the heater.

15. Vertical Primary Heat Exchanger

Cylindrical, multi-pass heat exchanger captures all radiant energy, eliminating the need for heavy refractory.

16. Drain Valve

One of two drain valves located at the bottom of the heat exchanger. A third drain valve is located on the secondary heat exchanger. This allows for complete winterizing and drainage of the heater.

17. Viewing Port

Allows for easy burner inspection.

18. Weather-Proof Jacket

Heavy gauge galvanized steel with a UV-resistant Polytuf powder coat is impervious to weather and corrosion. The Polytuf coating passes the 1000 hour salt spray test (ASTM B117).
