27.Nozzles

FIGURE 21A - One heat section with Option CD58, 60° Nozzle

Standard individually adjust- able louvers are installed in the nozzle discharge.

All Model LDAP heaters have discharge louvers but are available with additional louvers and/or nozzle discharge air options. Optional louver and discharge nozzles are shipped separately for field installation. Model LDAP 800 and 1200 heat sections have independent airflow and do not require the same discharge options. Each pack- age includes illustrated installation instructions.

Option CD32 consists of additional louvers that are installed perpendicular to the standard individually adjustable louvers. By installing the optional perpendicular lou- vers, the two sets of louvers can be adjusted to direct airflow in any of the four directions, enabling the installer to select and increase or decrease the coverage area.

Option CD57 is a 30° discharge nozzle. Option CD58 is a 60° discharge nozzle. Option CD59 is a 30° discharge nozzle with 4-way louvers. A nozzle may be installed at each discharge air opening in any direction. NOTE: Do not install 4-way louvers with a 60° nozzle.

Nozzles should be attached after the unit is suspended. Follow the installation instruc- tions in the nozzle package.

If the heater is operating in an area where an unusual amount of dust or soot or other impurities are present in the air, more frequent maintenance is recommended.

When any service is completed, be careful to reassemble correctly to ensure that no unsafe conditions are created. When re-lighting, always follow the lighting instructions on the heater.

Maintenance Schedule - The following procedures should be carried out at least annually. Refer to illustrations and follow the instructions in Paragraphs 29-42.

•Clean all dirt, lint, and grease from all combustion air openings and the venter assemblies.

•Clean all dirt, lint, and grease from all fan blades, fan guards, and motors.

•Check all heat exchangers both internally and externally.

•Check all burners for scale, dust, or lint accumulation. Clean if needed.

•Check gas valve(s) to ensure that gas flow is being shutoff completely.

•Check the vent system for soundness. Clean openings. Replace any parts that do not appear sound.
