I have a question about the G2FD046H17 multi-position coil. My question is that it comes shipped with an drain pan extension that according to direction it extends into supply air plenum. The problem I have is that I am using a variable speed blower NVSB1206X which the coil will attach to instead of a suply plenum. There seems to be no room for this extension between the air handler and coil. I have been installing york for some time and this is the first time using this particular coil. Its the only GF2D family coil I have seen this extension. The only reason using this coil now is to achieve 13 seer.
