Common Questions About Kitchen Hood Suppression Systems
How often do commercial kitchen hoods need to be inspected in NH?
In accordance with NFPA 96 and 17A standards, commercial kitchen fire suppression systems must be inspected every six months (semi-annually). These inspections ensure that the nozzles are clear, the fusible links are replaced, and the fuel shut-off is functional.
What happens during a semi-annual kitchen hood inspection?
Our technicians check the pressure in the cylinders, inspect the detection line, replace the fusible links (the metal pieces that melt during a fire to trigger the system), and verify that the gas or electric power to the appliances will automatically shut off if the system is activated.
Does LHR service kitchen hoods for restaurants in Manchester and Concord?
Yes! We provide comprehensive kitchen hood fire suppression services across the Seacoast and Greater Manchester areas. We focus on keeping your kitchen compliant with local New Hampshire fire codes so you never have to worry about a surprise inspection.
Why do I need to replace my fusible links every 6 months?
Over time, grease and heat can degrade the integrity of the fusible links. Replacing them during your semi-annual service is a mandatory fire code requirement to ensure the system triggers precisely when it is supposed to.

Our Clients Say
Posted on Google Jordan ShallowTrustindex verifies that the original source of the review is Google. Joe expedited my fire extinguisher inspection. I just googled them and they came down the next morning BEFORE my inspection. Thanks to the team. I highly recommend all of them and will use them in the future.Posted on Google RonTrustindex verifies that the original source of the review is Google. LHR Fire has been instrumental in getting our condominium complex's fire sprinkler system up to code. Our association is over 20 years old, and we discovered that the original installation had not been done correctly by a previous fire company, leading to leaks and ruptures over time. LHR worked with us to develop a plan for installing expansion tanks on the antifreeze lines and replacing the original check valves and sprinkler heads. They have diagnosed several longstanding issues. What impressed us most is their communication. They take the time to explain what they're seeing, discuss options, and work collaboratively to troubleshoot problems rather than simply replace parts. Overall, LHR is proactive rather than reactive. They take pride in doing the job right the first time, their technicians are knowledgeable and professional, and their pricing has been fair. I highly recommend them to anyone looking for a reliable fire protection contractor.Posted on Google Steven whiteTrustindex verifies that the original source of the review is Google. I wanted to take a moment to recognize LHR Fire Protection, especially Joe Keller, for the outstanding service they’ve provided over the years. We’ve worked with LHR Fire Protection at one of our business locations for several years, and they’ve consistently ensured that our fire protection systems remain up to code, fully compliant, and operating safely. Their attention to detail has given us tremendous peace of mind, knowing we can always rely on them to help keep our staff and customers safe. When we expanded to another location, Joe Keller conducted a thorough walkthrough, identified areas that needed to be brought up to current safety standards, and quickly implemented the necessary improvements. His knowledge, professionalism, and commitment to doing the job right made the entire process smooth and stress-free. We truly appreciate the professionalism, quality workmanship, and dedication to safety that Joe Keller and the entire LHR Fire Protection team demonstrate. I highly recommend them to any business looking for a dependable fire protection company. Thank you, Joe Keller, and thank you to the entire LHR Fire Protection team!
