I have had this fireplace for 7 years and not realize that there was a need to clean the glass now the glass has a white hue on it. I hesitate to remove the glass not sure if I will be able to get it back in properly. Is the glass cleanable at this point? Who do I call to do this or to replace the glass?

Yes, the glass on an Astria Fireplaces Gemini35DMN-B can be cleaned if it has a white hue. The white coating may result from impurities and minerals in the fuel. Approved cleaning solutions include non-ammonia-based glass cleaner, a 50/50 mixture of white vinegar and water, or gas fireplace/stove glass cleaner. The manual does not specify a contact for cleaning or replacement.
