Title: Not good - unsafe
Review: The heater was installed to replace an Olympian 6100 that was old. There was no need to do any modification to the gas lines. The heater caused the carbon monoxide alarm in my trailer to trip repeatedly. When lighting it, flames would "dance" across the pad. I called a gas technician and he told me not to use the heater as it was unsafe. Returned for credit.I have my doubts about this type of heater. Because it is a radiant heater, it only provides warmth when you are directly in front of it.
Is the review positive or negative?
