Wiring a new distribution motor for an Accentra

[Markinmaine]

I bought a Fasco B47120 blower to replace my old one in my older Harman Accentra. My old fan just has two wires not including the ground wire. The new fan has four.....black, red, yellow, and blue. It also has a grey one and purplish one as well going into a small box on the housing. I plan on disconnecting the housing from the motor to install.......what two wires do I connect to the stove?

Thank you in advance for your guidance....my first post after reading hundreds here to help me out with other pellet info

3 speed motor
yellow = neutral
black = high speed
blue = medium speed
red = low speed

To wire it at one speed (high) use the black and the yellow for the second wire? What do the grey and brown wires used for?

Thank you!

looks like some type of circuit breaker-gray and brown. High speed -yellow and black per "Golfeur"

I'm curious, which model Accentra do you own? Your blower looks a lot different than mine: https://www.hearth.com/talk/attachments/accentra_distribution_blower-jpg.120368/

brown and gray wire connected to a small circuit (resistance and condensers) to eliminate the peak voltage when the motor stops
there is less danger to the control board

Me thinks they have an insert?

Page 35 gives a good idea of it all.

Thank you all for your feedback and input. It is an Accentra insert installed in 2010.

One final thought for this eager noob......should I install as is or remove the housing and switch out just the fan?

This forum is awesome!

just the fan blade and motor. You would have dismantle half the stove to get to the housing. I have replaced a Dist. motor by myself w/ stove setting on the service rails and the stove up on 4x4 wood blocks. This gives you approx. 5 1/2" which is enough to drop motor out.

A really big and heartfelt thank you to those above that helped with my simple to you, complex to me distribution fan replacement. The install went well and was able to wire everything up perfectly......the moment of truth came when my 13yr old son and I put it in test mode and out came a strong and quiet flow of air into the room!

Thank you again.....I appreciate the help and kindness.
