There are three different ue pipe stubs available.
1. The  unit comes standard with the  largest, for use 
with 4” stainless steel ex pipe.
2. Part #1-00-674040 is for use with 4” PL vent starter 
pipe.
3. Part # 1-00-674039 is for use with 3” PL vent starter 
pipe and  also for  use with  3” aluminum  ex duct  for 
outside air connections.
The ue  stub assembly  base is  a round  plate which 
allows  it  to  swivel  to  allow  the  ue  pipe  to  exit  the 
mounting frame in other positions rather than straight 
up. See g. 28.

 Install the ue pipe insulation wrap. See Fig. 27. 
This ceramic insulation is precut to form around the ue 
pipe stub, to reduce heat transfer into the area around 
the rear of the hopper and motor area. 
See Fig. 29.

Fig. 27
Pre-cut ceramic insulation and (2) pieces of tie wire.
With larger ue pipes this bottom edge of the insulation will 
need to be trimmed to complete the wrap.
This picture shows the completed insulation 
wrapped  around  the  flue  pipe  from  the 
mounting frame upward.

* Floor protection must be used from hearth opening 
to 6" (152mm) in front of door glass and 6" (152mm) 
to each side of the stove body to protect combustibles 
from hot ashes. A minimum size will be 16.5" deep by 
30" wide and be made of a non-combustible material 
or meet UL approval.
 Test t the cast ash lip (See g. 25) on the shell 
frame mounting rails. The ash lip should slide on these 
side rails without lifting upward off of the rails as the 
ash lip is slid inward. A small clearance of about 1/16" 
is an ideal space between the legs of the ash lip and 
the hearth. This cast ash lip is a decorative part that 
does not and should not support any weight.
 Tighten the (2) 1/2" threaded rods up against the 
lintel of the replace opening.  It is also recommended 
to  use  some  form  of  anchoring  screws  through  the 
bottom of the shell into the hearth. There are up to 5 
holes provided. Note: It is a good idea to check the ash 
lip again. The frame may have shifted when the nal 
anchoring was completed. See g. 26.
 Complete the ue piping, and outside air piping, if 
used. Make sure the damper area is sealed.
  If  a  rear  exit  ue  conguration  is  used,  with  or 
without outside air, make sure the ue pipe termination 
clearances  are  followed  as  per  the  manufacturers 
recommendations.
