Anyone had someone install this recently? Can you tell me what is involved (Cost, time, etc.), would like it to be installed on back deck, gas fireplace is close to that spot so was hoping they could tie in there? Any recommendations on companies to do that around BR? Are the only other things you would need is hose/connectors to hook it to a NG generator?

The line by your gas fireplace is probably too small to tie into.

When we got a quote they where just going to put a T in on the main line and run it around the house externally. We decided against natural gas because we either needed a long gas run which was cheap but not ideal or a long wire run which was expensive. We thought they could just tie in to the gas that run through the house, that was not the case.

The whole house generator pulls 400k Btus on startup. Most likely-you’ll need to upgrade your meter at the house to a 2# meter-install a regulator for your house and have the separate high pressure line ran to generator location with a regulator at the generator. The fireplace line will not suffice for the generator gas demand.

Generators generally require more gas pressure than what runs to your house. You need to call your local gas utility to coordinate with a local plumber to get your unit installed.

I installed my own. I live in a 2 story and the ground floor at the rear of my house is a woodworking shop that takes up about 1/2 of the square footage. There are gas lines running to the stove upstairs and the water heater that was replaced with an electric one after Katrina.

I took a line off that one to run it outside the shop to a patio area so I can run my generator on natural gas and have the exhaust out in the open, so no hazard issues from carbon monoxide.

Total cost was under $30 for pipe, fittings and shut-off valve.
