E. Adjustable Flue Restrictor
The DV400S has an adjustable flue restrictor for maximum
performance for vertical installations. The unit is shipped with
the restrictor in the open position and should be left open with
any horizontal installation.
To access the adjustable flue restrictor bolt you must take the
following steps:
1. Remove the front face of the unit.
2. Remove the glass and set in a safe
place.
The adjustable bolt can be accessed by reaching through the
firebox to the back of the unit. See Figure 22.
The amount to close the restrictor will depend on the vent
height. If the vertical height is 20 feet or more, the restrictor
can be closed all the way. Anything less will require some
setting less than closed. The setting will vary depending on
the installation.
Any offsets in a vertical installation will restrict the system and
the flue restrictor will not need to be closed as much.

F. Clean the Glass
To clean the glass, use a non-abrasive, mild cleaning solution.
(For example, a glass cleaner or for stubborn film, an oven
cleaner.) Apply an adequate amount to the glass and wipe off
with a damp cloth. Be sure all cleaner is thoroughly rinsed from
the glass.
G. Install the Glass
After cleaning the glass, carefully place the Glass Frame
Assembly onto the unit by positioning the tabs at the bottom of
the frame into the slots. Pull the latch releases forward and hook
over the glass frame.
H. Optional Door Trim Kit Installation
The decorative trim can be installed at this time.
1. Lay the front face on a flat surface being careful not to
damage it.
2. Remove the lower shield by removing the (3) screws.
3. Lay the door trim onto the front face and put the shield
back in position and attach with the screws provided and those
removed earlier.
