Converting Class-A Metal Chimney To Direct Vent System - Regency Contura RC500E Owners & Installation Manual

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 chimney system.
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 ANSI 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
Factory Built Metal Chimney, the IPI/CPI
switch on the handheld remote control/
transmitter must be turned to CPI (Continu-
ous Pilot Ignition) at all times. This will avoid
nuisance pilot outages during operation
of this appliance. 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).

5. Pull the flex pipe down through the ceiling
support box, until it protrudes approximately

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.
