Leaks must be repaired at once to prevent damage to the heater. NEVER use petroleum-based stop-leak compounds.

To perform hydrostatic test:

1.Connect fill water supply. With bleed valve open, fill heater with water. When water flows from bleed valve, shut off water. Close bleed valve. Carefully fill the rest of the system, making sure to eliminate any entrapped air by using high-point vents. Close feed valve. Test at standard operating pressure for at least 24 hours.

2.Make sure constant gauge pressure has been maintained throughout test.

3.Check for leaks. Repair if found.

Raypak Integral Cold Water Protection

CAUTION: Damage due to internal condensation may occur if the heater inlet water temperature does not exceed 50°F (22°C) within 7 minutes of start-up.

XTherm heaters are equipped with an integral cold water protection system. Units equipped with the dual injector pump system are designed to operate with heater inlet water temperatures down to 50°F continu- ous. Under start up conditions the dual injector system can operate with fluid temperatures down to 32°F. Operation at lower temperatures will create unwar- rantable damage to the injector pumps. XTherm WH and WHP models equipped with single injector pumps are designed for typical domestic hot water and com- mercial pool heating operating conditions respectively. Contact your local representative or the factory for applications assistance.

Pump Selection

The heater is equipped with an integral cold water pro- tection system that includes dual modulating injector pumps to pull the required flow from the system loop and a heater pump, sized by the factory, for the opti- mal T across the primary heat exchanger. The system is designed for continuous return temperatures from 50°F to 180°F.

Feedwater Regulator

Raypak recommends that a feedwater regulator be in- stalled and set at 12 psi minimum pressure at the highest point of the system. Install a check valve or back flow device upstream of the regulator, with a manual shut-off valve as required by local codes.

Piping

All high points should be vented. A heater installed above radiation level must be provided with a low wa- ter cut-off device (sales order option F-10). This heater, when used in connection with a refrigeration system, must be installed so that the chilled medium is piped in parallel with the heater with appropriate valves to prevent the chilled medium from entering the heater.

The piping system of a hot water heater connected to heating coils located in air handling units where they may be exposed to circulating refrigerated air, must be equipped with flow control valves or other automatic means to prevent gravity circulation of the heater water during the cooling cycle. It is highly recommend- ed that the piping be insulated.

Air-Separation/Expansion Tank

All heaters should be equipped with a properly sized expansion tank and air separator fitting as shown in Fig. 13.

Three-Way Valves

WARNING: Three-way valves intended to regulate system water temperatures by reducing flow in the boiler should not be used.

XTherm heaters have an integral cold water protection system to maintain required temperatures and flow
