WARNING: Improper installation, adjustment, alteration, service, or maintenance can cause property
damage, injury or death. Read the installation, operation, and maintenance instructions thoroughly
before installing or servicing this equipment.
INSTALLATION INSTRUCTIONS
Installation should be done by a qualified agency in accordance with the
instructions on this sheet and in compliance with all codes and requirements of authorities having jurisdiction.
Tools Required: Ratchet or preferably cordless screwdriver with 5/16"
socket and 3/8" socket (or 3/8" wrench); 7/16" wrench
1. Preparation
All holes are punched at the factory. Use #1/4-20 x 3/4" long machine
screws where specified in the instructions. Otherwise, use the #10 x 1/2"
long sheetmetal screws.
Except for the crate bottom, remove the shipping crate from the heater.
Leave the heater attached to the crate bottom.
2. Install Top & Bottom Filler Panels on Heater
(Filler panels are the two unpainted pieces that "fill-in" the space between the heater and the blower cabinet.)
Install Top Filler Panel (See FIGURES 1 and 2) - Remove the screws
from the top back of the heater and re-insert them attaching the top filler
panel (use slotted holes). Position top filler panel with the rear flange
going down.
FIGURE 1 Install Top

Install Bottom Filler Panel (See FIGURE 2) - Locate the holes in the
bottom of the blower adapter back. Using these holes, install the bottom
filler panel with the rear flange up.
3. Install Cabinet Front Legs on Heater (See
FIGURE 2)
Slide the edge of one of the legs (legs are interchangeable) in next to the
inner side panel of the heater. Fasten the leg to the heater back panel using
the 1/2" long sheetmetal screws. Using the 3/4" long machine screws,
attach the leg to the bottom filler panel. Attach the other front leg.
4. Gasket Strips

Cut the self-adhesive gasket strip into two10-inch
pieces. Attach one of the
strips to each side of the
top of the blower housing
(parallel with the sides).

5. Assemble
Filter Channels
The filter channels are created by assembling the filter brackets and the
"L" shaped filter angles. The filter brackets are designed to be used with
either 1" or 2" filters. If using 1" filters, attach the filter angles to create
a 1" channel on the filter brackets. If using 2" filters, attach the filter
angles to create a 2" filter channel. Follow the instructions in the illustrations.
Sizes 25-125 (See FIGURE 4) - Attach one angle to the top filter bracket
and one angle to the bottom filter bracket.
