If you smell gas nowLeave the building without using switches, flames, or phones indoors. From outside, call 911 if there is immediate danger and call your gas utility. Contact a private-side contractor only after the area is declared safe.
The short answer
The existing branch and manifold should be checked against the new equipment schedule. Shutoffs, quick-disconnects, restraint devices, ventilation interlocks, and inspection scope may also change.
What matters in this situation
Commercial and multi-unit gas work adds operational consequences: multiple occupants, shared piping, equipment schedules, inspection coordination, and the need to document what can safely remain in service.
Details that help define the next step
- Old and new equipment input ratings
- Manifold and branch sizes
- Existing connectors and restraints
- Hood/interlock coordination
These details help establish scope; they do not replace an emergency response, onsite inspection, utility decision, permit requirement, or manufacturer instruction.
How a careful service process is organized
- Start by documenting old and new equipment input ratings and manifold and branch sizes.
- Confirm existing connectors and restraints and hood/interlock coordination before the scope is finalized.
- Have cut sheets for every changed appliance and kitchen plan ready for the onsite team or authority.
- Use the findings to define the appropriate commercial gas line repair scope, required testing, and any next authority or trade.
What to have ready when requesting service
- Cut sheets for every changed appliance
- Kitchen plan
- Shutdown window
- Permit and inspection contacts
What not to do
Do not assume equal physical size means equal gas demand. Keep relevant tags, notices, equipment information, and safely obtained photos available for the people handling this specific situation.
