Bring the fuel-supply questions forward
An existing fuel connection is a starting point, not confirmation that it can supply a new generator. The selected model, connected appliances and supply route need to be considered together.
- Natural gas: identify the existing supply and ask what capacity review or connection work is needed.
- Propane: share tank capacity if known, other connected equipment and how replenishment is arranged.
- For either fuel: discuss the route between supply and generator, rather than assuming the shortest visible route is suitable.
Plan placement and access together
Candidate locations should be reviewed against the equipment instructions and applicable requirements. Nearby openings, service access and the route for electrical and fuel work all matter.
- Identify possible locations without committing to a pad or fuel-line installation in advance.
- Note access constraints and existing structures or equipment near those locations.
- Ask how routine maintenance access will be preserved once the installation is complete.
Match backup coverage to your priorities
List the equipment you want to protect and which loads must operate together. Generator sizing and load-management decisions should follow the assessment, not a promise to run everything without qualification.
Know what the written scope includes
Before approving a project, confirm equipment, fuel work, electrical work, site preparation and any permit or inspection responsibilities. Ask how startup, the customer walkthrough and maintenance information will be handled.
