We have an older Coleman wall Natural Gas heater. The glass is missing where you can look at the pilot light (some foil has been stuck in there). Is there a certain type of glass we can put in there? We are selling our house and the inspector said to replace it.

We are selling our house and the inspector said to replace it. Check With your local HVAC company to find the part or call Coleman/Evcon with your model and serial number and tell them your looking for a sight glass for this heater. You may even check the parts side of Coleman/Evcons web site. Good luck.
