STANDARD MODEL COIL APPLIED DIRECTLY ON TOP
AND OFFSET TO THE LEFT ON NARROW FURNACE

1. Notch support rail on underside of coil cabinet to provide

clearances for gas furnace flange. This rail is not visible

from front of coil. To locate position of notch, place coil dir-
ectly on top of gas furnace with overhanging portion en-
tirely on left side as in Fig. 4, Alternative C. Mark location

of gas furnace flange on coil casing. Remove coil from top
of furnace. Using tin snips, make a notch in rail large

enough to allow clearance for gas flow furnace flange.

2. Place coil on top of gas furnace. Make sure coil is shifted

completely to left side, and notch is sufficient so coil rests

on top of furnace cabinet.

3. Prepare and install block--off plate. See Fig. 4, Alternative

C. Using field--supplied sheet metal, cut a block--off plate to

be attached to bottom left side of coil casing. This plate pre-
vents air leakage from overhanging portion of coil. Attach

plate using sheet metal screws.

4. Continue with normal installation practices. See Connect

Refrigerant Piping.

Downflow Cased Coil Installation

1. Place N--coil on supply duct opening.
2. When coil width matches furnace width, furnace can be

placed directly on the cased coil.

NOTE

:

In downflow installation with a 4--way multipoise

furnace, break off perforated duct flanges on furnace. See Furnace
Installation Instructions.
