SECTION A (See Figures 2-6 on page 3.)
1. If the heater is installed, turn off the gas and the electric
power.
2. Add Suspension Points
• If the heater is a Model F or FE factory equipped with four-
point suspension (Option BJ6) or a Model B or BE, skip to
Step 3. (NOTE: The two hanger brackets in the package will
not be used.)
• If the heater is a Model F or FE equipped with standard two-
point suspension, follow Steps a) through d) below to con-
vert to four-point suspension. Two hanger brackets are in-
cluded in the option package for this conversion.
a) Remove the carton, the wooden crate bottom, and the outer
side panels of the heater.
b) Position a new hanger bracket on the front portion of the in-
ner side panel (See Figure 2 for location). Remove the screw
from the inner side panel at that location. Holding the bracket
tight to the top of the heater, re-insert the screw through the
slotted hole and attach the bracket to the inner side panel.
The bracket must be tight to the top of the heater.
c) Replace the outer side panel.
d) Repeat Steps b) and c) on the opposite side of the heater.
e) If the heater is already installed, suspend from the new hang-
ers. (See Figure 3.) Heater must be level.
3. Remove the Horizontal Louver Assembly -- Remove the hori-
zontal louver assembly that is factory-installed in the front of
the heater (screws are on the sides). Save the screws and the
louver assembly. This louver assembly will be re-inserted in the
outlet of the downturn nozzle.
4. Install the Downturn Nozzle Side Panels -- Use the same
holes and the screws that held the louver assembly (removed in
Step 3) to attach the side panels of the downturn nozzle. (See
Figure 4.)
5. Attach the Downturn Nozzle Top Panel -- Using the screws
in the kit, attach the top of the downturn nozzle to the nozzle
sides and to the front of the heater. (See Figure 5.)
INSTALLATION NOTE: Wherever possible, always insert
screws with pointed ends inside the nozzle.
6. If installing either Option CD3 or CD5 (nozzles with two
sets of side panels and two tops), attach the two additional nozzle
side panels to the side panels already installed. Attach the addi-
tional top to the new sides and the top installed in Step No. 5.
(See Figure 6.)
7. Re-Install the Horizontal Louver Assembly -- Attach the
horizontal louver assembly removed from the front of the heater
to the side panels at the outlet of the downturn nozzle. Adjust
the louvers to obtain the desired air deflection.
8. Installation of Option CD2 or CD3 is complete. If you are
installing Option CD4 or CD5 (Option CD5 may be installed on
blower models only), follow the instructions in Section B on
page 4 to add the vertical louvers.
If option installation is complete and the heater is installed, be
sure that it is level. Turn on the electrical power and the gas.
Light the heater, following the lighting instructions.
If option installation is complete and the heater is not installed
and the wooden crate bottom has been removed, the bottom of
the heater must be supported with plywood or appropriately
placed boards when it is raised for suspension. If the bottom is
not protected, the bottom access panel could be damaged. In-
stall the heater in accordance with the instructions provided in
the heater installation manual.
CAUTION: To avoid getting burned, adjust
the louvers while the heater is not in
operation. If adjustment is required after the
heater is in operation, wear protective gloves.
WARNING: Failure to use four-point
suspension could cause gas valve failure and
subsequently personal injury, death, and/or
property damage.
