SHIELD (WS6
rame a hole in a combustible wall for an interior wall
shield, as shown in igure 24 (rear vent) and igure25
(top vent) whenever a wall is penetrated. This shield
maintains minimum clearances and prevents cold
air infiltration.
The termination cap location must meet all local and
national codes and not be easily blocked or
obstructed. See igure 17, page 12.
If the hole being penetrated is of noncombustible
materials, a 9 diameter hole is acceptable.
Secure the shield to the framing as shown in igure26.
The last section of vent may require cutting a piece of
minimum installation (MI) pipe or using a slip section
pipe, depending upon wall thickness and appliance
location. See igure 27.

Figure 28
Rear Vented Appliances Venting Clearances
2. INSTALLING THE REAR VENT HEAT
SHIELD
a. or horizontally terminated rear vent appliances,
the flue heat shields MUST be placed 1 above
the top of the vent between the wall shield and
the base of the termination cap. The shields are
attached to the wall shield and base of the cap
with two screws each. When installed, the caps
shield will rest under the wall shields shield. The
shields must have at least 1½ overlap. See
igure 27. Depending on the installation, the
shields may be too long and will require
trimming. If the shields are too short, material
must be added.
b. Minimum Venting Clearances
Horizontal runs off the back of the appliance to
the wall shield:
1 sides and bottom of vent
or top clearance, see igure 28.
Horizontal runs inside a wall (heat shields must
be installed):
3 air space on top of vent
1 air space on sides and bottom of vent
Vertical Runs:
1 air space around vent.
4. CHASE/TERMINATION INSTALLATION
igure 30 and Table 1 specifies minimum vent heights
for various pitched roofs. Vent sections may have to
be cut to a certain length.
These vent heights are necessary for safety and do
not ensure draft-free operation. Trees, buildings,
adjoining roof lines, adverse conditions, etc. may
create a need for a taller vent should down drafting
occur. See igure 31 for multiple vertical terminations.

simply slide the flared end of the inner flue of the VP
section over the inner collar on the appliance. At the
same time, insert the outer flue into the outer collar
on the appliance. Push the vent section into the
appliance collar until all the lances have snapped into
place. Tug slightly on the vent to confirm it has
completely locked in place.
Note: Squeezing the pipe slightly to fit may be
necessary.

4. ASSEMBLING THE SLIP SECTIONS
Slip sections should be snapped into the first mating
piece, then expanded to their desired length, making
sure that a 1½ overlap is maintained between the
two sections of the slip section. The two sections of
the slip section then need to be secured by driving
two screws through the overlapping portions of the
vent. See igure 35. This will secure the slip section
to the desired length and prevent it from separating.
The slip section can then be attached to the next
section of vent.
Figure 35
Figure 36
3. ASSEMBLING MINIMUM INSTALLATION
(MI SECTIONS
MI sections are non-unitized so that they can be cut to
a certain length. To use these sections, they must be
cut to length from the non-expanded end. See
igure34. They can then be attached by first
connecting the expanded end of the MI inner flue with
the inner flue from the adjacent vent section and
securing with three screws. The expanded portion of
the MI inner flue must overlap completely with the
untreated end of the adjacent vent section. The outer
flue can then be inserted into the adjacent outer flue
expanded end and attached to the next vent section
with three screws. The other end of the MI vent section
can then be attached by fitting a snap lock section to it
and snapping it together as normal.
Figure 34
2. ASSEMBLING VENT SECTIONS
a. Start the flared inner flue of Section A over the
inner flue of Section B.
b. Insert the outer flue of Section A into the outer
flue of Section B. See igure 32.
c. Once both inner and outer flues are started, press
Section A into Section B firmly until all lances
have snapped into place. Tug slightly on Section
A to confirm it has completely locked into place.
See igure 33.
Note: Make sure that the seams are NOT aligned in
order to prevent unintentional disconnection.

1. HIGH ALTITUDE INSTALLATION
or U.S. installation, appliances are tested and
approved for elevations from 0-2000 feet. When
installing this appliance at an elevation above 2000
feet, National uel Gas Codes require a decrease of
the input rating by changing the existing burner orifice
to a smaller size. Input should be reduced 4% for each
1000 feet above sea level. Check with the local gas
utility for proper orifice size identification. The correct
orifice is available from your Heatilator distributor.
or Canada, appliances are certified for elevations
from 0-4500 feet. When installing this appliance at
an elevation between 0-4500 feet in Canada, the input
rating does not need to be reduced. When installing
this appliance at an elevation above 4500 feet in
Canada, check with local authorities.
Note: This appliance and its manual shutoff valve must
be disconnected from the gas supply piping system dur-
ing any pressure testing of that system at test pressures
in excess of 1/2 psi (3.5 kPa). The appliance must be iso-
lated from the gas supply piping system by closing its
manual shutoff valve during any pressure testing of the
gas supply piping system at test pressures equal to or
less than 1/2 psi (3.5 kPa).

3. GAS PRESSURE
On both the standing pilot and the electronic ignition gas valves, the inlet pressure and manifold (outlet) pressure
taps are available on the face of the valve. Pressure taps are immediately upstream of the gas supply connection
and accessible for test gauge connection. Table 2 shows optimum gas pressure information. Consult your local
gas company for assistance in determining the proper orifice for you altitude or refer to ANSI Z223.1-latest edition,
AppendixF.
4. FUEL
a. Do not burn wood or other material in the appliance.
b. Natural or propane gas conversions necessary to meet the application need to be made by a qualified technician
using Hearth & Home Technologies brand specified and approved parts.
c. In the event your standing pilot appliance must be converted to use propane, you must use a CKVP conversion
kit. To convert to use natural gas, you must use a CKVN conversion kit.
d. If your intermittent pilot appliance must be converted to use propane, you must use a DCKP conversion kit. To
convert to use natural gas, use a DCKN conversion kit.
2. GAS LINE CONNECTION
The appliance is provided with a stainless steel flexible connector and manual shutoff valve (see igure 37). The
incoming gas line should be piped into the valve compartment and connected to the 1/2 IP connection provided on
the manual shutoff valve. All connections must be tightened and checked for leaks with a soap and water solution
or leak detector. Bleed the gas line to extract any air that may have been trapped inside the pipe. See igure 38 to
connect the gas line. Gas connections may also be made by taking out the knockout in the bottom pan to allow
connection through the bottom of the appliance.
WARNING!
This valve has been preset at the factory. Altering
settings may result in fire hazard or bodily injury.
