proper connection.
Prior to installation and connection of the vent
system to a Class A 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 Class A chimney system.
For Class A 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 deter -
mine if a negative pressure and/or leaky
chimney condition exists. Do not operate
the appliance until the problem is corrected.
IMPORTANT: If converting this appliance to
a Class A Metal Chimney, the IPI/CPI switch
on the handheld remote control/transmitter
must be turned to CPI (Continuous Pilot Ig-
nition) 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 it's
nominal length).
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 sup -
port 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.

3. Connect the end of the flex pipe section to the
underside of the Top Adaptor using 3 sheet
metal screws. Diagram 2.
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.
