[. . . ] DRAFT REGULATORS Model: B34 LISTED UNDER RE-EXAMINATION SERVICE OF UNDERWRITERS LABORATORIES, INC. [. . . ] Installation of this Draft Control should be made in accordance with the stove manufacturer's instructions. (NOTE: For the regulator to operate properly, the chimney must be clean and free of obstructions. ) Figure 1 *Selected sizes CSA and UL approved. Figures 2-7 Not CSA certified for solid fuels. The best setting for wood and coal burners is a draft gauge reading of . 04" to . 08" W. C. If a draft gauge is not available, with the draft regulator fully installed and a good fire burning, adjust the counterbalance weight closer to the gate for as low a draft setting as possible, without the fire dying or getting smoke-back with the stove door slightly open. To obtain higher heat levels, move the weight away from the gate to increase the setting. 4. Turn "knurled nut" counter clockwise for less draft, clockwise for more draft. When adjustment is made for desire draft, lock the "counter balance weight assembly" in place by tightening the "hex nut" located under the "knurled nut" against the gate. For best combustion efficiency, stack temperature (below the draft regulator) should be 350°F to 450°F for dry wood.
