Pro-Warmer XL Grate Drive Motor???????

What does the grate drive motor do?? I see a shaft going from it to the combustion chamber but i never see it turn on? Also i know Prowarmer is out of business but where can i get a copy of a manual for it? If anyone has one can they scan it and e-mail it??

Thanks in advance..............

Hello Montana ProWarmer,
The grate motor was primarily used to move the burn grate front to back to help keep the build-up to a minimum. The motor turns/moves at a slow rate and needs to be working for proper operation. I am familiar with these units and can explain more if needed. Send me a PM.
