24/7 Emergency: (877) 256-0161A semi-annual inspection found the Ansul R-102 piping packed with hardened grease. We cleared or replaced every blocked fitting, flushed the lines and capped every nozzle.
Client: A busy restaurant kitchen · Commercial kitchen
The challenge
When the nozzles of this Ansul R-102 system came off for inspection, several pipe nipples, elbows and nozzle holders were completely filled with hardened, carbonized grease. Grease vapor had got in through nozzles whose blow-off caps were missing or clogged, and had worked back into the piping above the ceiling. In a fire, the agent would have been blocked before reaching the appliances.
What we did
Every affected nipple, elbow and nozzle drop was unthreaded and removed, from the hood line back to the overhead piping.
Fittings that could be saved were cleared with degreaser and wire rods. Those too corroded or packed to clear were replaced with new Schedule 40 black iron pipe and fittings.
The whole manifold was flushed with dry nitrogen to confirm an open path through every branch.
New UL-listed rubber blow-off caps went on every nozzle to keep grease vapor out of the orifices.
The system was re-tagged with a State Fire Marshal service tag under license C16-976500.
Results
Confirmed by the nitrogen flush after the repair.
Blow-off caps are now a set check at each semi-annual service for this kitchen.
With little disruption to the kitchen.
