St., New York, N.Y. 10036.
Clearances
1. In selecting a location for installation, it is necessary to
provide adequate accessibility clearances for servicing and
proper installation. A front clearance of 36" (91.4cm) is
recommended. Do not block outlet or inlet air openings on
the front grill.
2. The DVC-35 minimum wall depth is 3/4" (19mm) and
maximum wall depth is 10" (254mm). The maximum wall
depth may be extended using the model DV-1190 extended
flue kit. The use of tubes not supplied by the manufacturer
results in unsatisfactory performance.
3. The DVC-35 can be attached to the wall or recessed into the
wall up to 9 1/2" (241mm) in depth but the minimum 3/4"
(19mm) vent/air intake system wall depth must be main-
tained.Example:Iffurnaceisrecessedintothewallatadepth
of91/2" (241mm), the minimum wall depth mustbe10 1/4"
(260mm).
4. The wall in which the furnace is recessed has (0) zero
clearance to the furnace sides and top.
5. When using side discharge registers, SOR-1 or SOK-1, the
furnace cannot be recessed into the wall.
6. Clearancetosidewallorcombustiblematerialis4"(102mm).
7. Ceiling clearance is 4" (102mm).
8. Floor and rear wall clearance is (0) zero inches.
9. Clearanceof18"(457mm)isrequiredtosidewallorcombus-
tible material when flush mounted SOR-1, side outlet regis-
ter is used.
10. The minimum distance from the center of the vent cap to the
nearest outside corner or obstruction is 12" (305mm).

VENT LOCATION
Maintain spacing of vent away from
landscaping and building overhangs.

anypressureregulator.Incaseofregulatormalfunction,
the six (6) feet (1.83m) distance will reduce the chance of
gas entering the vent cap.
Locating Wall Opening
The furnace is to be located on an outside wall. Locate wall studs
so that wall opening will be located between wall studs. The
furnaceis141/8"(358mm) inwidthandcanberecessedbetween
standard 16" (406mm) on center wall stud. The wall opening
required as shown in Figure 2 is a diameter of 7 1/2" (191mm).
A template is provided in furnace carton for positioning furnace
on the wall. Also, refer to Figure 2 and Figure 4 for positioning
the furnace on wall and for locating gas line connection.
Installing Optional Side Outlets

of the furnace at the required clearances of 18" (457mm) to
adjacent wall or combustible material as shown in Figure 3.
1. Turn "OFF" all electric power to the furnace.
2. Remove the front panel from the furnace.
3. Remove the (2) #8 x 3/8" (9mm) screws that attach the inner
shield cover plate to the inner shield.
4. Scribealinebetweenthefourdimplesontheoutercasingside
to form a square.
5. Drilla pilothole withinthe scribedsquare onthe outercasing.
Remove the sheet metal within the scribed square with a tin
snips or comparable tool. Attention! Do not cut the electrical
wires located between the outer casing and the inner shield.
6. Insert the 5" x 5" (127mm x 127mm) inner boot through the
outer casing. Align the clearance holes on the inner boot with
the screw holes on the inner shield. Attach inner boot to inner
shield with (2) # 8 x 3/8" (9mm) screws removed in Step 3.
7. Place the register over the 5 1/2" (140mm) square opening
with the louvers set for the desired direction and mark the
mounting holes using the register as a template.
8. Drill (2) 1/8" diameter holes in cabinet side and attach the
register with (2) #10 x 1" (25mm) provided screws.
9. Installation of SOR-1 is completed.
Side outlet kit, SOK-1, 10" (254mm) boot assembly with regis-
ter, for warm air discharge into an adjoining room may be
installed on either side of the furnace at the required clearance of
4" (102mm) to adjacent wall as shown in Figure 3.
To install SOK-1, please use Steps 1 through 5 in the SOR-1
instructions for DVC-35 furnaces.Now, use the followingSteps to
complete installation of the SOK-1.
1. Using the inner and outer boots as hole templates, mark and
drill (4) 1/8" (3mm) diameter holes in the inner shield and (4)
1/8" (3mm) diameter holes in the cabinet side.
2. Locateandcuta63/4"(171mm)squareopeningthroughwall.
