Bard Bayrd Furnace 403293A - Manual (Page 9)

9. Rgmove four screws that secure bottom plate to cas­
ing sides. Remove bottom plate; save screws,
10. Install top plate, removed in step 2, where bottom
plate was. Secure with four screws. Inducer outlet is
now lined up with vent outlet in top plate.
11. Stand up furnace with top plate down. Line front duct
flange up with holes. Place bottom plate on top of
duct flange and secure both to casing with four
screws.
12. Install junction box on bottom plate using two #6B
screws removed in Step 2. Junction box cover and
screw of junction box must face front of furnace.
13. Gasket around flue collar must be in place. If gasket
is loose, glue It. If gasket is damaged, replace it.
14. Install a single wall vent pipe section (minimum length
30 inches) (Field-Supplied) to inducer outlet with three
equally spaced screws. This pipe serves as an in­
ducer outlet extension to which an appropriate vent
can be attached. Due to minor variations in vent pipe,
available from different manufacturers in the field,
and to assure the tightest seal possible, inducer out­
let extension is not supplied with furnace. Additional
vent pipe sections or Type B1 adapter may then be
added when installing the furnace.
WARNINGS If Inducer outlet extension Is shorter than
30 Inches and chimney or vent becomes blocked, com­
bustion products may be drawn Into furnace. This could
cause nausea or asphyxiation, resulting In Injury or death.
15. Conversion from as-shipped configuration is now
complete.
SECTION 6 — ALLOWING FOR CLEARANCES.
WARNING: Do not Install furnace on Its back, doing so
could cause a fire, resulting In damage. Injury or death.
Establishing clearances from combustible material.
Locate clearance label on inside of front door. See Figure 6.
WARNINGS Furnace Installation must meet all minimum
clearances from combustible material specified In this
manual and all applicable codes. Failure to provide re­
quired clearance between furnace and combustible mate­
rials could cause a fire, resulting In damage, injury, or
death.
WARNINGS This furnace Is A.G.A. design certified for
direct Installation on wood flooring for upflow and hori­
zontal positions.
• Do not install furnace on carpeting, tile or other
combustible material.
• Do not Install furnace In a closet In horizontal
position.
• Do not Install furnace on wood flooring without
special base In downflow position.
Doing any of the above could cause a fire resulting in
damage, injury, or death.

1. Upflow Installation.
Upflow position is approved for installation on
wood flooring. Typical upflow furnace installa­
tions are an alcove, attic, basement, closet, ga­
rage, or utility room. See Figure 6 or furnace
clearance plate for minimum clearances to com­
bustible materials.
2. Horizontal Installation
a. Horizontal position is approved for installa­
tion on wood flooring. Typical horizontal fur­
nace installations are an alcove, garage, at­
tic, or crawl space. See Figure 6 or furnace
clearance plate for minimum clearances to
combustible materials.
b. Attic Installation.
Line contact is permissible for furnaces
installed in horizontal positions. The in­
tersection of furnace top and sides forms
a line. This line may be in contact with
combustible
material. However, maintain
a 6" clearance to vent connection unless
Type B1 vent is used. See Figure 7.
