I just installed a new set of vent free gas logs. Everything is great accept for they are loud. You can hear the sound of the gas flowing through the system. I've never had vent free logs before so maybe they are all this way, but I doubt it.
What could be causing this? Only three possibilities that I can come up with are: (1) this is normal, (2) the flexible hose I used is too small, or (3) I bought a poorly designed log set.
What do you guys think? I'm hoping for #2, but can having an undersized flexible hose cause it to be louder than it should be? The new hose I bought is small (3/8" OD). The hose packaging said it is good for up to 34,000 BTU/Hr and the logs are rated at 32,000 BTU/Hr.
