Product Overview

The Raypak Hot Surface Igniter Kit is an OEM replacement component for compatible Raypak heating equipment. Designed for a 120V hot surface ignition system, it provides the heated surface used to ignite gas during the burner startup sequence. When a technician identifies a failed igniter, replacing this component can help restore normal heater operation. This kit supports targeted ignition-system service without requiring replacement of the complete heater.

Ideal For

• Pool service professionals replacing a diagnosed faulty hot surface igniter.
• Commercial pool operators maintaining compatible Raypak Hi Delta heaters.
• Equipment owners sourcing an original Raypak replacement part for a scheduled repair.

Key Features

• Original Raypak service part for specified heater applications.
• Rated for 120V hot surface ignition operation.
• Listed for select Hi Delta commercial pool heater models.
• Also specified in parts lists for certain XTherm heating systems.
• Replacement component intended for servicing the existing ignition system.

Benefits

• Helps restore burner startup when igniter failure is the confirmed cause.
• Supports component-level repairs while retaining serviceable heater equipment.
• Gives technicians a manufacturer part number to match against the heater’s illustrated parts list.
• Helps simplify maintenance purchasing when the correct replacement has already been identified.

Compatibility

Listed Hi Delta applications include models 992, 1262, 1532, 1802, 2002, 2072, and 2342. Raypak also specifies this igniter in parts documentation for certain XTherm 1005, 1505, and 2005 configurations, including selected indirect pool heating systems.

Compatibility depends on the complete model designation, manufacturing date, and equipment configuration. Match the replacement against the heater’s applicable parts list and installed component before ordering. A shared brand name or similar heater capacity alone does not establish fit.

Installation and Service

Installation by a qualified pool heater technician is recommended because replacement involves electrical connections and gas-fired equipment. The technician should confirm the cause of the ignition problem, inspect related components, and follow Raypak’s service instructions.

An ignition fault does not automatically indicate a defective igniter. Proper diagnosis helps avoid replacing a working component when another condition is preventing startup. After installation, the technician should verify normal ignition and heater operation.

Confirm Before Ordering

Confirm the heater model, serial number, required igniter voltage, and manufacturer replacement number. If additional gaskets, mounting hardware, or related ignition components are needed, verify the current kit contents before scheduling service.

Specifications

Customer Q&A

Does this fit every Raypak pool heater?
No. It fits specified applications. Confirm the complete model and applicable parts diagram before purchasing.

What does HSI mean?
HSI means hot surface igniter. The component heats electrically to provide an ignition source during burner startup.

Will this fix a heater that will not ignite?
It can resolve a failed-igniter condition. Other faults can produce similar symptoms, so diagnosis should come before replacement.

Is this the same as a flame sensor?
No. The igniter initiates combustion; a flame sensor detects flame. Raypak lists these as separate components in the referenced XTherm parts diagrams.
