Duct Work Installation
We strongly recommend that the hot air ductwork be installed by a home
heating specialist. If doing the installation yourself, before you decide
which installation will best suit your needs, consult a qualified heating
technician and follow his recommendations as to the safest and most
efficient method of installation. This furnace can be installed in three ways,
as a stand alone unit, parallel, and in series with an existing furnace.
SUPPLY AIR (HOT AIR) PLENUM
The warm-air supply duct shall be constructed of metal in accordance with
NFPA 90B, 2-1.1. The plenums installed to the furnace shall be constructed
of metal in accordance with NFPA 90B, 2-1.3. When installing this furnace
the hot air plenum is to have a minimum height of 24” (610mm) if the top
of the first vertical section is not flush with the top of the first horizontal
section of ductwork. If the top of the plenum is flush with the top of the
first horizontal section of ductwork then the minium height is 15” (381mm).
RETURN AIR (FRESH AIR)
The return (fresh) air intake on the furnace is on the rear of the unit. The
ductwork must be mechanically attached to the unit or UFB908 blower
box with sheet metal screws to ensure a proper operation.
STAND ALONE INSTALLATION
If installing this furnace as a stand alone unit, ensure all local codes
and all instructions in this manual are followed, including clearance to
combustibles, floor protector specifications and safety warnings.
