equipped with any of the

gas control options in the

table, be sure these parts

are available at the job site.

3.2.1 Converting

Furnace for Higher CFM

Application

This furnace was factory assembled with the air throughput range listed on the rating

plate. If the application requires a higher CFM than listed on the rating plate, refer to

the requirements and instructions in the APPENDIX, page 30.

1. Refer to FIGURE 2A. Remove the screws attaching the limit control bracket to the

side of the furnace. Carefully pull the bracket/control assembly through the hole. (Do

not disconnect wires.)

FIGURE 2A - Limit

Control Location -

When reversing airow,

the limit control must

be re-located. The limit

control MUST be on the

discharge end of the

heat exchanger

Location of the factory-

installed Limit Control

Bracket on a Furnace with

Standard Airow Direction

Duct furnaces are equipped with directional air bafes between the heat exchanger

tubes. Facing the control compartment of the furnace, the standard direction of airow

is from the rear of the furnace (gas valve location) toward the front of the furnace. If the

installation site requires airow from the front to the rear, the unit may be eld adapted

by re-locating the limit control and reversing the position of the directional air bafes.

Instructions for Reversing Airow

2. Refer to FIGURE 2B and follow Steps a)-d) to reverse the direction of the bafes.

a) Remove Screws "A". Individually lift each bafe slightly

and slide forward. Remove all bafes completely from the

heat exchanger.

b) Remove Screws "B" and the top bafe support assembly.

Re-position the assembly on the opposite end of the heat

exchanger and attach.

c) Remove Screws "C" and the assembled bottom bafe

support and brackets. Plug the holes in the heat

exchanger bottom by re-inserting the screws in the holes.

Position the assembly on the opposite end of the heat

exchanger and attach using eld-supplied sheetmetal

screws.

d) Re-install all of the individual bafes by reversing

procedure in Step a) above.

bafes.

3. Relocate the limit control.

a) At the discharge end on the same side of the heat exchanger, measure down

4-1/2" (114mm) and across 1-11/16" (43mm). Using that point as the center, punch

a 2-1/4" (57mm) diameter hole in the side panel.

NOTE: It may be necessary to move cable connections. Re-insert screws to plug all

holes in the side panel. After the limit control is installed, the cable connections may be

re-attached using eld-supplied sheetmetal screws.

3.2.2 Instructions for

Reversing Airow by

Changing Directional

Air Bafes in the Heat

Exchanger

NOTE: If the unit has optional outer

side panels, locate the limit control and

remove the outer panel on that side of

the furnace.
