Power Vent System Kit
The City 40, City 50, City 60 & City 72 Series power vent system is designed to allow the installation of this gas appliance when typical vent
congurations (Non-Power Vent Direct Vent Systems With no Fan Assist) are not possible due to excessive osets, long or negative vent runs, etc.
When installed as a power vent appliance, this unit is designed to use ex or rigid venting.
INTRODUCTION
IMPORTANT
•• The instructions contained in this manual must be read carefully prior to installation of this appliance.The instructions contained in this manual must be read carefully prior to installation of this appliance.
• 120 Volt AC power is required for this appliance to operate. A receptacle box, receptacle, and cover are
provided. See the "Wiring the Unit" section in this manual. Electrical power must be brought to the appliance
by a licensed electrician.
NOTES
• Rigid pipe is approved for up to 72 feet (21.95 m).
• Flex pipe is approved for up to 40 feet (12.19 m) using 2 X 946-756-- 20 foot (6.10 m) ex kits.
There are two options available when installing this unit as a power vent appliance:
• End of line ush horizontal power vent system (Part #946-535): ush power vent fan acts as the termination cap and sits ush to the outside
wall. Allowed for horizontal termination only.
• Inline power vent system (Part #666-945): power vent fan terminal is incorporated into the vent run - allows for both horizontal and vertical
termination.
This unit may be terminated vertically or horizontally using the Power Vent Systems available. See the following pages for various vent congurations
using rigid or ex & vertical or horizontal terminations. The instructions contained in this manual must be read carefully prior to installation.
