CONVERTING CLASS-A
METAL CHIMNEY TO
DIRECT VENT SYSTEM
Prior to installation and connection of the vent
system to a factory-built or masonry chimney,
the chimney must be inspected and thoroughly
cleaned by a qualified service person, such as
a certified chimney sweep or home inspection
service.
The direct vent system must not be connected
to a damaged factory-built or masonry chimney.
For factory built, zero clearance, and masonry
chimneys cleanout doors and caps or plugs for
cleanout tee fittings and ash dumps shall be
secured in place and sealed before installing a
Direct Vent system within the chimney.
If the appliance shuts off during operation,
contact a qualified service person to determine
if a negative pressure and/or leaky chimney
condition exists. Do not operate the appliance
until the problem is corrected.
Approved for US Installations Only
The use of an existing chimney as an air intake
is not covered under the ANS Z21.88-2014/CSA
2.33-2014 test methods and the resulting ITS/
WHI product certification. The code Authority
Having Jurisdiction must be consulted prior to
proceeding with this installation method.
Converting a Factory Built Metal
Chimney
Important : If converting this appliance to a Fac-
tory Built Metal Chimney, the IPI/CPI switch
on the hand held remote control/transmitter
must be turned to CPI (Continuous Pilot
Ignition) at all times. This will avoid nuisance
pilot outages during operation of this appli-
ance. See Remote manual for setup of this
IPI/CPI switch.
1) Remove the existing chimney cap.
2) Measure the distance from the top end of the
chimney to the bottom of the ceiling support box,
add 3" (76mm) to this measurement, and cut
a section of the 4" flex pipe to that length (the
flex should already be extended to its nominal
length).

3) Connect the end of the flex pipe section to the
underside of the Top Adaptor using 3 sheet
metal screws. Diagram 2.
4) Pass the flex pipe down through the center of
the chimney system, and center the adaptor
on the top of the chimney pipe. Drill four 1/8"
diameter holes through the adaptor and into the
chimney top. Insure that you are in fact, drilling
into the metal on the chimney. Twist-lock the
Termination Cap onto the Adaptor. (Diagram
3 and 4).

5) Pull the flex pipe down through the ceiling
support box, until it protrudes approximately
3" (76mm). Connect the flex pipe to the Retro
Connector by slipping it into the
4-3/4" diameter sleeve on the top side of
the Connector. Use 3 sheet metal screws to
assemble these two parts.
6) Push the flex pipe back up into the ceiling
support box, center the Retro Connector,
and attach it to the support box, or decorative
sleeve for double wall solid packed pipe, with
the sheet metal screws (supplied). The holes
in the Retro Connector are pre-punched.
Diagram 5.
7) The connection between the appliance and the
Retro Connector may be completed with sec-
tions of black direct vent pipe, together with an
adjustable length.
