I just read this in my manual on page 4, STEP 4, the 2nd section a:
Draft Channels -- The draft channels are located on either side of the grate and are removable for two purposes:
Please locate "brick" at this time. Open viewing door, look inside stove through door opening. The brick will be between two metal channels, about 4" from the top of your stove. Now look for draft channels located on either side of the grate. Loosen the two 7/16 bolts and remove the channels. Locate holes in back of stove body. this is where your stove drafts. The two holes should be cleaned every 4 to 6 weeks with a vacuum or brush. NOTE: Entire vent system should be cleaned every 4 to 6 weeks.
- To allow for better draft on warmer days and for weaker chimneys.
- For access to clean the stove's vent system.
IMPORTANT: Draft channels may be left off while stove is in operation, but bolts must be reinserted. This will not harm the stove but will slightly decrease efficiency. In some cases, it will increase draft in low drafting chimneys.
I see what I think are the "holes in the back of the stove body" (the angled "house" shaped holes), but I've never had anything that covered them. Did my dealer forget to give me something?
