We have a Cedar Ridge Hearth LP gas stove space heater - new. It does not appear that the gas is reaching into the unit. Dual regulator being used, 3/4" copper tubing also. Manual says stove must be installed by licensed technician - why? This is no different from a grill. Can you help?
Thanks for using JA.
The main reason for a certified technician is that there are certain things about vent free appliances that are somewhat technical. First it is an appliance that is using gas combustion for a heat source inside the house with no venting requirements.
This concept in itself needs to be examined and controlled by someone who has been trained in combustion air requirements, flame impingement, and other problems that can cause carbon monoxide poising.
A grill generally is outside in the open air, has no controls or pilot systems, and is used momentarily then extinguished. If it is used indoors, generally there is a fan exhaust system directly above the grill.
Now to get to your problem. You should verify the tank is on, the dual regulator is working correctly, and all of the air has been properly bled out of the lines.
Once this is complete, let me know and we can go through the lighting procedure to determine if there is a problem.
Thank you for your response. We understand the concern for most folks messing with gas. My husband has furnace technician experience from time in the mobile home industry. The basics remain the same. Correction: 3/8" copper tubing approximately 5' in length. Again, verified pressure at tank, and again from tank through shut off valve. Does not appear to be entering the stove itself. Held in control knob, to light pilot, in excess of 2 minutes several attempts. Still nothing. This is a 2nd stove as we felt maybe the first was defective. Please advise.
