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
Detached garages may require underground piping; attached garages may involve finished walls, fire separations, and impact protection. The gas scope should be coordinated with the heater installer and electrical/venting work.
What matters in this situation
An appliance hookup is only as safe and reliable as the piping that feeds it. The existing branch, shutoff, connector, venting responsibilities, and combined gas demand all need to be understood before connection.
Details that help define the next step
- Attached versus detached garage
- Heater model and mounting location
- Route through or outside the home
- Vehicle and storage clearances
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 attached versus detached garage and heater model and mounting location.
- Confirm route through or outside the home and vehicle and storage clearances before the scope is finalized.
- Have heater specification sheet and garage photos and dimensions ready for the onsite team or authority.
- Use the findings to define the appropriate gas appliance hookup scope, required testing, and any next authority or trade.
What to have ready when requesting service
- Heater specification sheet
- Garage photos and dimensions
- Existing gas-system information
- Permit authority and installation schedule
What not to do
Do not route exposed piping where vehicles or stored equipment can strike it. Keep relevant tags, notices, equipment information, and safely obtained photos available for the people handling this specific situation.
