Desa W32AOSA Instruction manual

IMPORTANT:If you are staining an unnished mantel (W32AUA
only), remove any sawdust, dirt or oils. This will prevent blem-
ishes from appearing under the stain. Stain mantel before
assembling according to manufacturer’s instructions. Apply
sanding sealer.
IMPORTANT: If you are painting an unnished mantel
(W32AUA only), assemble mantel before painting. Follow
directions listed on paint for wood products. Apply base coat
and top coat following directions listed on product.
Note: Gather all mantel pieces together before assembling.
ASSEMBLING MANTEL
WARNING: Use only 1/2" screws to attach metal
angle brackets. Damage to mantel will result if other
screws are used for this purpose.
IMPORTANT: More than one person is required to lift
assembled mantel. Lift mantel by leg assemblies. Lifting
by header or mantel top could damage mantel.
When assembling mantel do not tighten screws completely
until told to do so. There should be some play in the pieces
to allow for proper alignment and best possible t. It is very
important that more than one person assemble mantel. Panels
must be held in proper alignment to each other while tightening
screws to assure fewer gaps and proper surface alignment.
When tightening screws, do not over tighten. This may cause
threads to strip. The supplied Allen wrench should be used
rather than a power screwdriver. Panels have threaded inserts
installed at screw locations. Screws should start and turn easily
in threaded holes when assembled according to instructions.
Do not force screws into holes.
IMPORTANT: There is a serial number label inside of right
side panel and on outside package. When calling to request
technical assistance or for replacement parts please have
that number ready.

ATTACHING TOP OF MANTEL

Figure 5). Align back of top with back of sides.
2. Using six 1 1⁄4" screws with washers, attach top to header/
leg assembly (see Figure 5).
Brackets
Right Side
Figure 1 - Attaching Brackets to Side
1. Lay right side panel (#2) face down on a soft surface
to avoid marking nish. Attach four brackets with 1/2"
screws to bottom of right front leg (#3) leaving screws
slightly loose. Face brackets out (see Figure 1). Place
right front leg (#3) over right side (#2) as shown in Figure
2, paying close attention to direction arrow pointing up
on panels. Align threaded holes with brackets on side.
Start four 1/2" screws through brackets. Align bottom of
side and leg assembly so they are ush with each other.
Hold these pieces securely in alignment while tightening
(but not over tightening) screws.
2. Assemble left side (#4) and left leg (#5) as described in
step 1.
3. You may prefer to lay mantel face down on a soft surface
instead of upright to position header. Position header (#6)
between leg assemblies with direction arrow pointing up
(see Figure 3). Attach header assembly blocks (#8) with
1 1/4" screws and washers (see Figure 4).

FIREPLACE INSTALLATION
1. Fireplace should be fully assembled. See Assembling
Fireplace in replace owner’s manual.
2. Place mantel base close to installation location. See re-
place owner’s manual for installation clearances. Leave
enough room to get behind mantel once replace and
mantel assembly have been attached to base if installing
a replace with ange.
3. If installing gas replace, install gas line. See Connecting
to Gas Supply in replace owner’s manual. Remember
to leave access to the gas shutoff valve somewhere on
the base or where it is accessible to the user. Check
for leaks. See Checking Gas Connections in replace
owner’s manual.
IMPORTANT: If your replace has a nailing ange see Installing
Fireplace with Flange. If your replace does not have a nailing
ange see Installing Fireplace without Flange, page 4.
INSTALLING FIREPLACE WITH FLANGE
1. Position replace on base centering left to right. Care-
fully position gas lines. IMPORTANT: Use caution when
positioning replace on base as base may scratch.
2. With assistance, carefully place mantel over replace (see
Figure 6). Fireplace nailing anges will be to the inside of
mantel. Align mantel over threaded holes in base. Make
sure back of mantel is ush with back of mantel base.
Adjust replace as necessary.
