All insert owners: What size of blower do you have or recommend. I have recently had to replace my fan motor on my R14 Regency and I am less than impressed with the output of the blower. The guy who did the work put in a 115 CFM fan , I believe the original was 135CFM. I can feel the difference and fear I will have to spend more $$ to get what I wanted originally. Just wondering what is your CFM output for your insert is...I am not getting enough heat back from my unit now with less CFMs.
