## Questions & Answers

**Q: does the motor come with the mounting bracket and paddle fan as shown in the picture?**
A: no it does not. Usually the all in one combo set is not compatible. You could purchase separately the fan and bracket for cheap

**Q: Will this motor fit Envirofire EF3 ?**
A: Sorry, I do not know. I can say that the blower motor as viewed on line for your Envirofire  EF3 looks to be different than the Harmon Combustion Fan that I purchased. My fan has only three bolts to secure it. Caution also  in selecting the correct fan blade. They come in both single and double paddles.

**Q: “It 100% fits an advance with a 1999 build date,Chain driven?”**
A: Not sure , but I don’t think so , I have a Harmon Accentra 52i  with direct shaft drive.

**Q: Will this fit the free standing accentra 2 model**
A: It fit my freestanding p61
