Not to add fuel to this debate... but... smh.. Everyone operates their grills the way they choose, but when accidents happens by not following the owners manual instructions... It’s always wise to operate your grill with caution and common sense especially in inclement weather and all pellet grill manufacturers have warnings about operating their devices in rain and water.
1. Direct quote from MAK Grills FAQ page... MY AUGER IS JAMMED WITH PELLETS—WHAT DO I DO?
BBQ wood pellets are nothing more than compressed hardwood sawdust that is extruded*into a pellet shape. If the pellets absorb moisture (either from rain or ambient moisture in*the air) they break back down into sawdust and swell with the moisture.* This creates an*almost cement-like mess, which takes a good bit of work to clear out.* This is why we*recommend that if you are not using your grill for 1-2*weeks or more, especially during rainy*weather, you empty your hopper and burn through whatever pellets are in the auger tube. Should your auger tube get jammed with decomposed pellets: End Quote... So no Pellet Grill is immune from issues caused by inclement weather, rain or water... if it hasn’t happened yet, one day it could.
2. Can You operate your grill in the rain? Yes, but with common sense and caution... Perhaps use a canopy, cover the hopper with a weather proof cover and keep the electrical cords out of water... FFT... Everyone is free to operate their pellet grills as they see fit, just don’t complain when the “Opps” happens during a down pour because your Pellet Grill was not covered or protected... These investments are worth at least cover and a canopy... .02
