Fireplaces, Heating Stoves, Flues and Chimneys - vent free fireplace need a regulator?

The instruction manual states that a regulator must be put in line with this unit. I currently have a set of gas logs with a tee handle turn off approx 3 feet fron the fireplace that is ultimately connected to my natural gas main. Wouldn't the existing unit warrant the use of a regulator and, if so, where would it be located?
I would not begin the installation of this unit before having all of the facts. If I needed help would I contact a heating professional or a contractor that deals with gas pipe?
Thanks in advance for any insight anyone can offer.

A heating contractor could help you. However in the instructions I bet they list the psi or bar pressure you have to be around. Also, if look at where your gas comes into your house I'm sure you will find a regulator so I bet you will be good to go.

Thanks for the reply. I am glad to hear that there is probably already a regulator in-line. Will it tell me what it is "regulated" to? I figured that this would be the case and the fireplace manufacturer was just covering all of their bases but I wanted to make certain.

You may find a listing on the regulator but to be 100% sure you need a gauge.

Guessing doesn't cut it with unvented equipment. The margin of safety you have is narrow, and improper gas pressure can easily cause equipment to overheat and produce large amounts of carbon monoxide.

Frankly, you should attempt to do repairs or installation on unvented equipment unless you know exactly what to do and how to do it --- which you don't.

I should try to do it? I don't understand your response SeattlePioneer. It sounds like you are ainst my attempting to move forward with this but you said I should?? Just want to understand where you are coming from on this.

I think he left out the word "not" in his statement. Vent free gas fireplaces should not be serviced by anyone that is not properly trained. You may get it right, but you may not and they, if improperly adjusted, can cause sooting of your home or even serious health issues.

Call someone that knows what they are doing.
