how do you know if you installed the air filter right? My filter place has an open area to the right of the filter and a metal mesh like filling the right side of the filter area. The area shows insert filter with an area going to the right side. right now. Have I done it wrong? Should the arrow be aiming to the left of the furnace?

You can determine if the air filter is installed correctly in a Water Furnace 300A11 3 Series by ensuring it is placed in the optional 1" filter rack, which is suitable for duct connection and has the same return opening size as the duct flanges. The filter rack extends 2.25 inches from the unit, and proper alignment with the return opening is necessary for correct installation.
