INSTALLATION OF VERTICAL SECTION

(

Common Part for Radial and Anemostat Diffusers)

RDM, RDS, RDL, ADM, ADS, ADL, 2E592 and 2YU34

1. Remove louvers from front of heater by gripping louver close to

spring and compressing spring until other end of the louver is free.

2. For Dayton Unit Heaters - Remove bird screen from venturi opening.

3. Position vertical section over venturi outlet and rotate vertical section

until holes in mounting brackets align with matching hole in front of

heater.

4. Secure vertical section with four No. 6-32 x 3/8” (9.5mm) mounting

screws (supplied) as shown in Figure 1.

INSTALLATION OF RADIAL DIFFUSER

RDM, RDS, RDL, 2E592 and 2YU34

1. Mount vertical section (supplied as part of radial diffuser). (Refer to

INSTALLATION OF VERTICAL SECTION above.)

2. Loosen all six screws in radial diffuser hub until blades move freely

(See Figure 2, View A).

3. Rotate the radial diffuser hub clockwise until the radial diffuser can

be inserted into the vertical section.

4. Insert blade rods into matching holes in vertical section while rotat-

ing the radial diffuser hub counter-clockwise. (See Figure 2, View B).

5. Center all blades radially and tighten screws enough to allow each

blade to rotate yet maintain a set position.

6. Rotate each blade to desired position and tighten screws to secure

blades.

INSTALLATION OF LOUVERED DIFFUSER

ON MUH HEATERS

LDS, LDM and LDL

1. Louvers may be left in place or removed from the heater. (Refer to

Step 1, INSTALLATION OF VERTICAL SECTION ).

2. Insert mounting springs into four 3/16” (4.8mm) holes in inside

flange of front cover.

3. Place louvered diffuser against front of unit.

NOTE: Position locating tabs toward the top and sides of heater

INSTALLATION OF LOUVERED DIFFUSER

ON HUHAA & DAYTON HEATERS

DS, LDM and LDL

1. Louvers may be left in place or removed from the heater. (Refer to

Step 1, INSTALLATION OF VERTICAL SECTION).

2. Place louvered diffuser against front of unit.

NOTE: Position locating tabs toward the top and sides of heater

flange.

3. Secure louvered diffuser to heater with three (3) screws (provided)

through the mounting tabs.

INSTALLATION OF ANEMOSTAT DIFFUSER

ADM, ADS, AND ADL

1. Mount vertical section (supplied as part of anemostat diffuser).

(Refer to INSTALLATION OF VERTICAL SECTION.)

2. For small (-S) and large (-L) diffusers, slide anemostat over vertical

section and secure with three No. 10-32 x 3/8” (9.5mm) bolts and

nuts. (See Figure 3, View A).

3. For medium (-M) diffuser, slide anemostat into vertical section and

secure with three No. 10-32 x 3/4” (19mm) bolts, nuts and spacers.

(See Figure 2, View B).

INSTALLATION OF MOUNTING BRACKETS

B10, B20, B30, B50, 6X966, 6X967, 3UG64, 3UG65,

2YV16, 2YV17, 2YU91 and 2YU92

1. Locate the position of the heater wall mounting bracket. Refer to

Figure 4 for minimum mounting clearances. Refer to Figure 5 for

mounting bracket dimensions.

2. The hole locations for the mounting bracket can be determined by

holding the bracket in position and marking through the holes.

Mounting bracket dimensions with hole locations are also given in

Figure 5.

3. A minimum screw size of 3/8-inch (9.5mm) diameter should be used

to mount the bracket to the wall or ceiling. A heavy washer should

be used between the bolt head and the bracket. USE THE TYPE OF

SCREW THAT IS BEST SUITED TO THE BUILDING STRUCTURE.

4. Remove four bolts and washers from top of heater and secure unit

mounting bracket to top of heater using the four bolts and washers.

(See Figure 6).

5. Bolt the unit mounting bracket to the wall mounting bracket using

one 1/2-13 pivot bolt, two flat washers, one split lockwasher, and

one 1/2-13 nut. (See Figure 7).
