INSTALLING DAMPER CLAMP ACCESSORY FOR VENTED 
OPERATION
When  used  as  a  vented  heater,  appliance 
must be installed only in a solid-fuel burning 
replace  with  a  working  ue  constructed of 
noncombustible  material.  You may  use  this 
heater as a vented product. There are three 
reasons for operating your heater as a vented 
model:
1.  The replace does not meet the clearance 
requirements for vent-free operation.
2.  State or local codes do not permit vent-
free operation.
3.  You prefer vented operation.
If reasons  number  1  or  2 above apply, you 
must permanently open chimney ue damper. 
You must install the damper clamp accessory 
(not provided). This will insure vented opera-
tion (see Figure 10). The damper clamp will 
keep  damper  open.  Installation  instructions 
are included with clamp accessory.
See chart below for the minimum permanent 
ue opening you must provide. Attach damper 
clamp so the minimum permanent opening will 
be maintained at all times.

you must maintain the minimum distance

to the replace, you must install appliance 
at least 5" above the combustible ooring 
(see Figure 9).
