RECESSED FIREPLACE INSTALLATIONS WHEN
INSTALLED WITH 8" DUCT KIT
When the hot air ducts will pass through a masonry
surround built around the fireplace, a grill box
extension kit must be used to make the face of the hot
air registers flush with the brick or stosne. Proceed as
follows:
1. Fit a 90
o
elbow to the top of each duct section.
Push down firmly to snap-lock them together.
2. Attach the duct sections to the hot air outlets on
top of the fireplace. Fasten them in place by
screwing three metal screws through the pipe and
into the fireplace hot air outlets. Be sure the face
of each elbow is parallel to the front of the
fireplace.
3. Screw grill box extensions onto standard grill
boxes using four metal screws. Slide grill box
assemblies over end of 90
o
elbows and adjust so
face of grill boxes will be flush with finished brick
or stone wall. Use two sheet metal screws to
secure each grill box assembly to the 90
o
elbows.
4. Slide 5 1/4" round duct extensions over inner grill
box duct collar.
If you have designed your masonry surround to extend
down over the face of the fireplace, you must also add
a masonry adapter for the front grill. An optional way
to deal with the front grill is to entirely remove it and
construct a soldier course of bricks over the opening.
(See finishing details on page 13.) Depending on the
amount of overlap it may also be necessary to add an
extension tube for the temperature probe access port
and replace the standard by-pass handle with an
extended version. (Consult your dealer.)
INSTALLING EXTENDED BY-PASS ROD AND
ACCESS PORT EXTENSION
1. Pull off top grill and remove set screw from by-
pass rod retaining collar.
2. Pull out existing rod, insert extended rod and
replace set screw. If necessary, access door on by
-pass chamber may be removed to facilitate
alignment of rod.
NOTE:
When bricking in the access port extension
sleeve (smaller one) and the extended by-pass rod
sleeve, make sure they are aligned properly.
