WARNING: Unit must be level for proper
operation. Do not place or add additional weight
to the suspended heater. See Hazard Levels, page
2.
If an optional downturn air nozzle is used, the unit must be sus-
pended from four points to ensure level suspension. Two hanger
brackets are included in the downturn option package and must
be field-installed on fan-type units with standard two-point sus-
pension. For additional information, refer to Paragraph 26 and
the instructions that are furnished with the option package.
When blower-type units are equipped with an optional blower/
filter cabinet, there are two suspension points on the blower cabi-
net hanger bar. Suspend a unit equipped with a blower/filter cabi-
net from four points, using the two heater hanger bracket assem-
blies closest to the front of the heater and the two suspension
points on the blower/filter cabinet.
If one of the optional, field-installed hanger kits has been ordered
for your heater, it will have been shipped separately. Each option
package includes a list of components and complete, step-by-step
assembly instructions.
Optional, Field-Installed Hanger Kits:
1) Four-Point Suspension (fan models only) - Option CK7
This option kit is designed to convert a fan-type heater from stan-
dard two-point suspension to four-point suspension. The kit con-
tains two additional hanger brackets.
2) Two-Point Swivel Connectors (fan models only) - Option
CK8 (See Figure 3.)
The purpose of this option kit is to adapt the standard hanger
bracket so that the heater can be suspended from 1", threaded,
stationary pipe. The swivel connector screws "into" the threaded
hanger bracket on the heater and "onto" the 1" threaded pipe used
for hanging the heater. The kit includes two swivel hanger con-
nector assemblies and two lock washers.
3) Four-Point with Swivel Connectors (fan-models only) -
Option CK9 (See Figure 4A)
This option package is designed to convert a fan-type heater from
standard two-point suspension to four-point suspension with
swivel connectors. By installing this kit the standard fan-type heater
can be hung from four 1", threaded, stationary pipes. The kit in-
cludes two hanger bracket assemblies, four swivel hanger con-
nector assemblies and four lock washers.
4) Four-Point Swivel Connectors - Option CK10 (See Figure 4A)
This option package is used on a heater that is already equipped with four-
point suspension to adapt it for suspension from four 1", threaded, station-
ary pipes. The kit includes four swivel hanger connector assemblies and
four lock washers.
5) Special Four-Point Suspension with Nearly Equal Loading (applies
to blower models only) - Option CK19
This suspension option is designed for special applications when a suspen-
sion system is needed that has nearly equal loading at all four suspension
points. Use this option in installations with spring isolation designed for
seismic protection or when threaded rod hangers are longer than twelve
inches.
Suspension points change with the addition of hanger kit Option CK19; see
Figure 4B.
9. Venting
These power-vented unit heaters are designed to operate safely and effi-
ciently with either a horizontal or vertical vent. (Horizontal vent run is rec-
ommended for maximum fuel savings.)
WARNING: Units installed in multiples require
individual vent pipe runs and vent caps. Manifolding
of vent runs is not permitted due to possible
recirculation of combustion products into the
building and possible back pressure effects on the
combustion air proving switch.
