Disconnecting gas equipment.

post #1 of 7
Thread Starter 

Just bought our first restaurant and am now faced with disconnecting and getting rid of all the old equipment.  The propane has been capped by the propane company and  the equipment has sat unused for about 4 months.  Any special precautions I need to take in order to disconnect the grill, stove, and fryers?  I've looked online and there is tons of information on initial installation but having trouble  finding an answer to this.  Thank you all in advance!

If you are uncertain you should seriously consider hiring a plumber with gas certifications to do the work for you.

But my experience is that there should be a shutoff valve at each gas connection. Turn it off, even if you know the gas has been turned off or capped elsewhere. Then use a proper fitting wrench to disconnect so you don't deform the fittings. Resist any temptation to use vice grips, channel lock pliers, or most adjustable wrenches... Including pipe wrenches.

If there is no shutoff valve for each appliance, or a main one in the kitchen, (which isn't to code, but many

older kitchens took these shortcuts to cut costs) then the gas would need to be shut off at the meter.

Something the gas company will insist a certified gas tech or licensed plumber should do. 


If however there are accessible shutoff valves, after they're turned off, and the hoses disconnected, they

need to be properly capped off until new appliances are connected. Just turning off the valves,

disconnecting the lines at the appliance and leaving the hose attached to the valve, or the valve uncapped

are both unacceptable, and considered dangerous. 


If you insist on DIY, DO your Mise en place-- get the proper sized nat gas caps BEFORE commencing the

disconnect. Also when capping, wrap threads  with gas approved (usually yellow these days) teflon tape.

If you ask this question call a professional.  Did the gas company purge the lines?

Well ... Don't be smoking any cigarettes when doing this job.

Yeah, or finishing off a Creme Brulee.

The above is also assuming a low pressure type gas service.
Bottom line here, if there are shutoff valves for each feed,
and youre not making modifications, its within the DIY realm,
but still illegal. Anything else, just hire a plumber, its a minimal
time job, half hour maybe, and any surprise
KA-booms will be easier on your insurance

I recently put in a propane stove.  From the tank to the stove there are three shutoff valves.  The stove is connected using a quick connect.  I paid the gas company to do the job.
