INSTALLATION
!WARNING: Failuretofollowtheseinstructionscarefullycouldresultin
poorperformance,propertydamage,personalinjuryordeath.
STEP 1. LOCATE VENT OPENING
Locate wall studs and center 9” vent opening a minimum of 22” for CDV15 or 24-1/8” for CDV25/33 above
the oor. To locate furnace at minimum clearance from oor, remove template from carton and set on oor
at location desired.
FormodelCDV15:
Position template no closer
than 1” from either side wall.
FormodelCDV25/33:
Position template 1” minimum from a
left side wall or 0” from a right side wall.
Check outside wall to be sure there is proper clearances around the vent cap. SeeFigure3. Next, mark
and cut out the vent openings on both the inside and outside walls (be sure to keep the holes level). See
Figure5. If a higher location on the wall is desired, raise bottom of template to desired height, make sure
template is level and centered between studs, mark and cut out vent openings.
STEP2. ROUGH-INGASSUPPLY
Install a ½” diameter gas supply line. This line can enter through the oor, side, or rear wall. For location
of gas connection to valve, See Figure 4. The gas supply line must have an individual manual shut off
valve located outside the cabinet, accessible from the room where the heater is installed. Install a drip leg
immediately ahead of the gas valve and provide a 1/8” N.P.T. plugged tapping, accessible for test gauge
connection, immediately upstream of the gas supply connection. The furnace and the individual shut off
valve must be disconnected from the gas supply piping system during any pressure testing of that system
at test pressures in excess of 1/2” psig (3.5kPa). The furnace must be isolated from the gas supply piping
system by closing the individual manual shut off valve during any pressure testing of the gas piping system
at test pressures equal to or less than 1/2” psig (3.5kPa).
STEP3. INSTALLINGFURNACEONSTANDARDWALLS(5”-9”)
Use only the exhaust tube, air intake tube, wall thimble extension, and vent terminal provided with furnace.
Do not attempt to lengthen the exhaust or air intake tubes, this could cause an imbalance in the furnace
resulting in poor performance and pilot outage, see Figure 6.
Extend the telescoping wall thimble extension (surrounding the wall thimble assembly) to approximately
9 inches. Center the wall thimble assembly in the 9-inch opening and attach to inside wall using eight (8)
screws. The wall thimble extension should extend through the opening and be adjusted so end of wall
thimble extension is even with outside wall. Install furnace ush to wall by sliding exhaust tube and air
intake tube through the wall thimble assembly. Secure the furnace to the wall with screws through each of
the four holes in the mounting brackets located on the back of the furnace. These holes are spaced so as
to allow the screws to enter into studs that are on 16-inch centers. On certain types of wall, anchors (not
provided) may be required.
Slide the vent terminal onto the exhaust tube and the air intake tube. Secure vent terminal and vent
terminal spacer plate to wall providing a slight downward slope to the vent tubes. This will prevent water
from entering. Anchors (not provided) may be required. Caulk around vent terminal spacer plate with putty
provided. See Figure 7.
NOTE: Some framing may be necessary to provide a at surface for the vent terminal spacer plate to butt
against, so rain cannot enter through cut out.

Figure 6. Replace with exhaust tube and
air intake tube from Kit No. VK33/9-15-B.
Discard the 5” telescoping wall thimble
extension that surrounds the wall thimble
assembly. Center the wall thimble assembly
in the 9” opening and attach to inside wall
using eight (8) screws. Install furnace
ush to wall by sliding exhaust tube and
air intake tube through the wall thimble
assembly. Secure the furnace to the wall
with screws through each of the four holes
in the mounting brackets located on the
back of the furnace. These holes are
spaced so as to allow the screws to enter
into studs that are on 16-inch centers.
On certain types of walls, anchors (not
provided) may be required.
From outside the building install the thick
wall thimble extension, Part No. 43835,
supplied in Vent Kit No. VK33/9-15-B by
sliding it through the cut out and over the
wall thimble assembly. The wall thimble
extension should be even with the outside
wall (some trimming may be necessary).
Slide the vent terminal onto the exhaust
tube and the air intake tube. Secure vent
terminal and vent terminal spacer plate
to wall providing a slight downward slope
to the vent tubes. This will prevent water
from entering. Anchors (not provided)
may be required. Caulk around the vent
terminal spacer plate with putty provided.
See Figure 7.
NOTE: Some framing may be necessary to
provide a at surface for the vent terminal
spacer plate to butt against, so rain cannot
enter through cut out.
