INSTALLING DAMPER CLAMP ACCESSORY FOR VENTED OPERATION
Note: When used as a vented heater, appliance must be installed only in a solid- fuel burning fireplace with a working flue and constructed of non combustible material.
If your heater is a manually controlled model, you may use this heater as a vented product. There are three reasons for operating your heater in the vented mode.
1.The fireplace does not meet the clearance to combustibles requirements for
2.State or local codes do not permit
3.You prefer vented operation.
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 29). This will insure vented operation (see Figure 10). The damper clamp will keep damper open. Installation instructions are included with clamp accessory.
See chart below for minimum permanent flue opening you must provide. Attach damper clamp so the minimum permanent flue opening will be maintained at all times.
