1 Approximate high fire heater outlet temperature based on the standard heater pump and the recommended connecting pipe size.
2 Minimum pipe size based on total equivalent feet of supply and return piping between the system loop and heater, not to exceed 2.7 ft of head at 70 gpm.

* Flow rates are shown for standard models. Pipe size selection not to exceed 2.7 ft hd pressure drop at 70 gpm (265 lpm)
** For High Temp/Process unit utilizing a single injector pump, pipe sizing to be based on the following:
H7-1005A - 87 gpm @ 3.5 ft (329 lpm @ 1 m) hd pressure drop
H7-1505A - 113 gpm @ 7.6 ft (428 lpm @ 2.3 m) hd pressure drop
H7-2005A - 116 gpm @ 8 ft (439 lpm @ 2.4 m) hd pressure drop
NOTE: System flow must be greater than boiler flow at all time for proper operation.

3.9.6. Applications and Modes - Primary/
Secondary Piping
The VERSA IC Control system is designed for a wide range
of applications. The installer/design engineer should refer
to the following Modes to determine which best fits the
intended application and functionality for the unit being
installed. Type H models of XTherm have three modes
available to them to address the various applications the
units can be applied to. Type WH units will only have the
WH configuration available to them for use with potable
water applications when directly connected to a hot water
storage tank. Type P units will only have the P configuration
available. For detailed information on the VERSA IC control
system, see the VERSA IC manual (5000.72). This manual
can be found in the document library at www.raypak.com.
Mode 1 (Type H Units Only)
This mode selection is for hydronic heating systems with
single or multiple heaters (Maximum 4 heaters) in primary/
secondary piping configuration with or without Outdoor
Air Reset (S4). See Figure 16 and Figure 17.
