If reasons number 1 or 2 above apply to you, you
must permanently open chimney flue damper. You
must install the damper clamp accessory (to order,
see Accessories, page 25). This will insure vented
operation (see Figure 10). The damper clamp will
keep damper open. Installation instructions are
included with clamp accessory.
