NOTES:
1. Two additional 7/8 ---in. (22 mm) diameter holes are located in the top plate.
2. Minimum return---air openings at furnace, based on metal duct. If flex duct is used, see flex duct manufacturer’s recommendations for equivalent diameters.
a. For 800 CFM---16---in. (406 mm) roun d or 14 1/2 x 12---in. (368 x 305 mm) rectangle.
b. For 1200 CFM---20---in. (508 mm) round or 14 1/2 x 19 1/2 ---in. (368 x 495 mm) rectangle.
c. For 1600 CFM---22 ---in. (559 mm) round or 14 1/2 x 22 1/16---in. (368 x 560mm) rectangle.
d. For airflow requirements above 1800 CFM, see Air Delivery table in Product Data literature for specific use of single side inlets. Th e u se of both sideinlets,a
combination of 1 side an d the bottom, or the bottom on ly will ensure adequate retu rn air openings for airflow requirements above 1800 CFM.

*5 in. or 6 in. (127 or 152 mm) vent connector may be required in some cases.
{5 in. ( 127 mm) or lar ger vent is required. Use a 4 ---5 (102---127 mm) or 4---6 (102---152 mm) in. vent adapter between furnace and vent connector.
4. If you touch ungrounded objects (and recharge your body
with static electricity), firmly touch a clean, unpainted
metal surface of the furnace again before touching control
or wires.
5. Use this procedure for installed and uninstalled (ungroun-
ded) furnaces.
6. Before removing a new control from its container, dis-
charge your body’s electrostatic charge to ground to pro-
tect the control from damage. If the control is to be in-
stalled in a furnace, follow items 1 through 4 before
bringing the control or yourself in contact with the fur-
nace. Put all used and new controls into containers before
touching ungrounded objects.
7. An ESD service kit (available from commercial sources)
mayalsobeusedtopreventESDdamage.
LOCATION
GENERAL
This multipoise furnace is shipped in packaged configuration.
Some assembly and modifications are required when used in any
of the four applications shown in Fig. 4.
NOTE: For high--altitude installations, the high--altitude
conversion kit MUST be installed at or above 5500 ft. (1676 M)
above sea level. Obtain high --altitude conversion kit from your
area authorized distributor.
