I have done some modifications to a Masterbuilt Electric Smokehouse because of what I perceived to be too much smoke flavor. First I drilled a hole in the top near the front right corner (opposite of the temp probe that controlls the heater) and installed a 1" vent. Added a couple of latches to the outside to pull the door firmly shut. And a small aluminum angle iron to the inside of the door on the hinge side to physically push the door seal into place when closing a hot smoker. Now I can visually check the amount of smoke coming out of the smoker. To get the "thin Blue Smoke" only 3 chips need to be added about every 30 minutes. This has eliminated what seemed to be stale smoke taste (Creosote ?). I was concerned that the electric element might not be adequate for the smoker if vented but found that the unit only needs to be heating about 50% of the time to maintain 225 degrees. water consumption (in the pan) has not changed either. I did install the wood chip pan modification supplied by masterbuilt because of a recall and that has had no adverse effect either.
4†in from front and 4†in from right side use a hole saw to cut a 1-3/8†hole through the outer skin, foam insulation and the inner skin. Push in a 1†black pipe nipple and secure with (2) 1†electrical box connector nuts. I used a suitable O-Ring on the outside to seal from moisture. Attach a suitable piece of aluminum tubing to the threads of the exposed nipple. The longer it is the more it is going to condense water in cold weather so keep it short. If you want to cook without the vent remove the aluminum tubing and lightly screw on a 1†pipe cap.
Use a metal switch cover plate (Blank, no holes in it but the mounting screw holes) turned up to hold water and attach under the vent on the inside of smoker with ¾†spacers and stainless screws.
Use a length of ½†X ¾†aluminum angle and screw the ¾†side to the door at the hinge side so that the ½†side pushes the seal into place when the door is closed. This prevents the magnetic seal from grabbing the box and distorting itself when closing.
Attach (2) latches (top and bottom) as shown so that they pull the door shut an additional 1/8†when they are latched. This prevents all distortion to the seal which might occur.
