FAQs:
Q: What equipment is the PVI 107775 Hot Surface Ignitor compatible with?
A: The PVI 107775 is documented for the PVI Low NOx TURBOPOWER application, but the manufacturer drawing does not provide a complete model-by-model compatibility list. Confirm the equipment model and serial number, the existing PVI part number, and the ignitor’s 1-inch insertion configuration before purchasing.
Q: Is PVI 107775 the same as Norton MB478844?
A: Yes. PVI’s part-number table associates PVI part number 107775 with Norton part number MB478844 and identifies a 1-inch insertion dimension for this configuration.
Q: What are the specifications of the PVI 107775 Hot Surface Ignitor?
A: PVI specifies a resistance range of 40 to 75 ohms, a 1-inch insertion dimension, 1800°F within 17 seconds at 102 ± 1 volts, and 4.25 to 4.75 amps at 132 ± 1 volts. The manufacturer drawing also lists a temperature of 3100°F at 132 ± 1 volts.
Q: How can I confirm that PVI part number 107775 is the correct replacement ignitor?
A: Confirm the number printed on the existing component or listed in the equipment parts documentation, then compare the equipment model and serial number, Norton identifier MB478844, and 1-inch insertion configuration. Do not select the ignitor solely by appearance because similar PVI ignitors may have different dimensions and part numbers.
Q: What symptoms may indicate that a PVI hot surface ignitor should be inspected?
A: A heating system that does not initiate burner combustion or experiences an ignition-related lockout may warrant inspection of the ignitor and the rest of the ignition circuit. These symptoms do not prove that the ignitor has failed, so the cause and correct replacement part should be verified before ordering.
