Yes, ventless natural gas heaters can emit an odor, mainly due to the trace amounts of odorant added to natural gas for safety detection. You might also notice a smell when they're newly installed, which is often due to the burning off of factory residues. Proper ventilation and regular maintenance can minimize any odors. However, if the smell is strong or persistent, it could indicate incomplete combustion or a malfunction, requiring immediate attention for safety.
