Raypak XTHERM 1005 - Manual (Page 3)

Project Name / Date
3. The igniter will be located to the side of the heat exchanger to protect the device from
condensation during start-up.
4. The ignition control module shall include an LED that indicates six (6) individual diagnostic
flash codes.
5. An external viewing port shall be provided, permitting visual observation of burner operation.
G. Gas Train
1. The pool heater(s) shall have a firing/leak test valve and pressure test valve as required.
2. The pool heater(s) shall have dual-seated main gas valve.
3. Gas control trains shall have a redundant safety shut-off feature, main gas regulation, shut-off
cock and plugged pressure tapping to meet the requirements of ANSI Z21.10.3/CSA 4.3.
H. Pool Heater Control
1. The following safety controls shall be provided:
a. High limit control with manual reset
b. Flow switch, mounted and wired
c. PSIG ASME pressure relief valve, piped by the installer to an approved drain
d. Temperature and pressure gauge (shipped loose)
2. The pool heater(s) shall be equipped with a PID modulating temperature controller with LCD
display that incorporates an adjustable energy-saving pump control relay and freeze
protection, and is factory mounted and wired to improve system efficiency; three water
sensors included (system sensor is loose)
I. Firing Mode: Provide electronic modulating control of the gas input to the pool heater.
J. Pool
