Installation Information

Installation should be completed by qualified service personnel experienced with gas-fired heating equipment. Raypak instructs technicians to disconnect electrical power, shut off the gas supply, and allow the appliance to cool before replacing the igniter. Installation procedures differ between Hi Delta and MVB/XTherm equipment.

Confirm Before Ordering

Verify the heater model, model suffix, voltage, and existing igniter configuration before purchase. Some larger Hi Delta models use more than one HSI, so more than one kit may be required depending on the specific appliance. Raypak notes that Hi Delta models 992–2342 use two hot surface igniters.
