ManualsBrandsOxbox ManualsFurnacesJ951X - 38k BTU - Gas Furnace - 95% AFUE

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

tested on the manufacturing line.

• 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

type igniter. Utilizes proven Smartlite

technology.

• Flexible category IV venting system: May be vertically

or horizontally vented using either a one-pipe or two-pipe

system for maximum ﬂexibility in installation.

• High Static Blowers: All models equipped with high static

blowers.

• 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 and stainless steel secondary heat

exchanger assures a long life.

• 60 second ﬁxed cooling cycle blower-off delay (TDR)

increases cooling performance.

• 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.

• Incorporates integrated control board with connections

for electronic air cleaner and humidiﬁer.

• Two piece door design enhances furnace appearance and

uses captured screws to prevent losing door screws.

• Blower Compartment: Sealed door to reduce air leakage

and insulated for ultra quiet operation.

• Sealed Vestibule reduces burner and inducer sound levels.

• Furnace Air Leakage: These furnaces comply with Energy

Star cabinet air leakage requirement of less than or equal to

2%. Keep the conditioned air ﬂowing to where it's needed.

• PolyPro by DuraVent: These furnaces have been tested

with and are approved to be installed with DuraVent’s PolyPro

venting system.

Furnace Models

95.0 AFUE

38,000 - 108,000 Btuh Input

The high efﬁciency upﬂow gas furnace may be installed free

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

or closet. Upﬂow/horizontal units come ready for upﬂow or

horizontal application. The extended ﬂush jacket provides a

pleasing “appliance appearance.” Design certiﬁed by CSA

for application in Canada and the United States.
