ManualsBrandsOxbox ManualsFurnacesJ801X - 54k BTU - Gas Furnace - 80% AFUE

• 100% ﬁred and tested: All units and each component

are tested on the manufacturing line.

• Low Boy Height: Easy to apply in low ceiling applications,

works well with taller high SEER coils, easier to handle

and install.

• Tubular primary heat exchanger: Heavy gauge

aluminized steel heat exchanger assures a long life.

• 30 second blower delay at start-up: Assures a warm

duct temperature at furnace start-up. Adjustable blower

off settings (60, 90, 120 and 180 seconds).

• 30 second post purge: Increases life of heat exchanger.

• Hot surface igniter: Innovative application of a silicon

nitride igniter. Utilizes proven Smartlite

technology.

• High static blowers: All models equipped with high static

blowers.

• 90 second cooling cycle blower-off delay (TDR):

Increases cooling performance.

• Flexible category I venting system: May be vented with

dedicated venting system or common vented with other

category one appliances.

• High efﬁciency blower kits: Maximize efﬁciencies. On

select units, a SEER improvement of up to 1 point is

realized.

• Multi-speed direct drive blower: Designed to give a wide

range of cooling capacities. Switches on PCB, provide

ultra easy motor speed selection.

• LP convertible: Simple burner oriﬁce and regulator spring

change for ease of convertibility.

• Diagnostic lights for easy troubleshooting without

counting ﬂashes: Dedicated light for ﬂame signal strength

and 2 lights in combination to indicate all other fault codes

with easy to recognize states without counting ﬂashes.

• Integrated control board: Incorporates connections for

electronic air cleaner and humidiﬁer.

• Two piece door design: Enhances furnace appearance

and uses captured screws to prevent loose door screws.

• Blower Compartment: Insulated for ultra quiet operation.

• Meets Title 24 Standards: Min. 350 CFM/Ton, .58 watts/

CFM and ≤ 2% cabinet leakage.

• Meets SCAQMD and SJVAPCD rules 1111/4905: For

low NOx limit of 40ng/J.

Induced Draft - 80+% AFUE

Input 45,000 - 126,000 BTUH

J801X* Series

High Efﬁciency Upﬂow/Horizontal and

Downﬂow Gas Furnaces

The high efﬁciency gas furnace may be installed free

standing in a utility room, basement, or enclosed in an

alcove or closet. The rounded corner jacket provides a

pleasing “appliance appearance.” Design certiﬁed by CSA

for application in Canada and the United States.

FEATURES and BENEFITS

SPECIFICATIONS

This furnace series is approved and certiﬁed by the

SCAQM and the SJVAPC Districts in the state of California

under each Districts’ Mitigation Fee Plan for shipment into

and sales in both districts.

For California installations in SCAQMD only: This furnace

does not meet the SCAQMD Rule 1111 NOx emission limit

(14 ng/J), and thus is subject to a mitigation fee of up to

$450. This furnace is not eligible for the Clean Air Furnace
