Ansul P34 Nozzle - 442088

The Ansul 442088 P34 Nozzle is a specialty discharge nozzle for ANSUL Piranha kitchen fire suppression systems, engineered for targeted spray coverage in specific appliance configurations. UL-listed for Class K fire suppression, the P34 provides a focused spray pattern suited to particular cooking equipment geometries where the wider DL nozzle spray pattern would either under-cover the hazard area or discharge agent outside the protected zone. Within the Piranha nozzle family, each nozzle designation — including the P34 and DL — corresponds to a specific appliance type, mounting position, and coverage area defined in the ansul nozzle chart for Piranha systems.

Correct nozzle selection in Piranha system design is non-negotiable for UL 300 compliance. The P34's targeted spray geometry is specified for particular high-risk cooking appliances in the Piranha system design documentation — installing the DL nozzle (443341) where the P34 is specified, or vice versa, produces an incorrect discharge pattern that may fail to achieve UL 300 rated coverage for the protected appliance. For fire protection contractors installing ANSUL Piranha systems, always verify the correct nozzle designation for each appliance using the Piranha system design documentation before installation. The piranha system and piranha systems documentation from authorized ansul distributors provide the complete nozzle selection matrix for all supported appliance types.

Install and aim the P34 per the ansul nozzle chart requirements for the protected appliance. Use the ANSUL laser pointer adapter (439876) to verify precise aim before locking the nozzle. Maintain nozzle caps on all P34 nozzles at all times except during system discharge — inspect caps at every semi-annual NFPA 17A and NFPA 96 service visit and replace any missing or damaged caps immediately. The ansul fire suppression system cost of a failed AHJ inspection due to wrong nozzle type far exceeds the cost of verifying correct nozzle selection at the design stage.

Install and aim the P34 per the ansul nozzle chart specifications for the protected appliance type and mounting position. Use the 439876 laser pointer adapter with a laser aiming tool to verify precise aim before tightening the nozzle locknut. Nozzle caps must be installed at all times except during system discharge — a missing cap allows grease and debris into the nozzle orifice. Inspect caps and nozzle aim at every semi-annual NFPA 17A and NFPA 96 service visit. Post-discharge: replace all nozzle caps, verify nozzle positions are undisturbed, and re-verify aim if any nozzle was disturbed during service.

What is the difference between the P34 and DL nozzle in the Piranha system?

The P34 (442088) provides a targeted spray pattern for specific appliance geometries; the DL (443341) provides a wide spray pattern typically used over deep fryers. They are not interchangeable — each is specified for particular appliances and mounting positions in the Piranha system design documentation. Always verify the correct nozzle for each position using the ansul nozzle chart.
