I installed a propane direct vent fireplace bought from Security Chimney International about 12 years ago. I now want to convert it to natural gas. I have phoned the company and they told me that the model is not being made any more so nothing is available but to check with a dealer. A dealer close to where I live said the same thing. What is involved in converting an old model fireplace from propane to natural gas?

This sounds like a "shop for me" question and not an actual how-to question. – Steven Jun 18 '13 at 19:46
I think the question needs to focus on what is involved in converting from propane to natural gas not how do you find the upgrade for your unit - which probably doesn't exist. Pictures and description of what you have would help, including if you have natural gas in your home and where it is compared to fireplace. – DMoore Jun 18 '13 at 20:14
I'm not sure I understand what you mean in the last part of your last sentence. The natural gas is being hooked up to the house and a there will be connection to the fireplace. The model of fireplace is Security Chimneys International PDV 33P. – user13541 Jun 19 '13 at 13:08
What is involved seems to be a fair question. Google finds "Security Chimneys," and their fireplace products link takes you to Lennox. Lennox's web page (lennoxhearthproducts.com/owner-resources/literature) includes manuals that describe the conversion process. I think most ship configured for natural gas, so perhaps you'll get lucky and find that when the installer converted, the removed orifices were left behind? – Tim B Jun 20 '13 at 17:10

The conversion kit usually consists of a different sized orifice to handle the LP fuel. I had to do this on my outdoor grill when I converted from LP to NG.
