Page 7

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-typeunits 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.

and blower models)

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.
