WARNING
Fire hazard. Do not install furnace on tiled floors or
carpeting. Failure to follow these instructions could
result in death or serious injury.
5. Locating the Unit - [See Table 1]
• Locate furnace so flue connection to chimney is short, direct
and consists of as few elbows as possible.
• Centralize furnace location with respect to supply and return
air ductwork. Central location minimizes trunk duct sizing.
• All models may be installed on combustible floors.
• Do not install furnace on carpet or tiled floors.

5.1 Upflow Installation

Maintain all clearances to combustibles. See Table 1.
The furnace is factory assembled for installation in the upflow
position. Locate return air opening on either side or base panel of
the furnace.

5.2 Downflow Installation

Maintain all clearances to combustibles. See Table 1.
When furnace is installed in downflow position on combustible
floor, the downflow floor base 550003032 may be used to ensure
required clearances. Refer to instructions provided with the base.
Return air opening maybe located on either side or base panel
(i.e. now at the top in downflow position) of the furnace.
• Rotate furnace 180° to desired position.
• Loosen four (4) nuts fastening oil burner assembly to
furnace. Rotate oil burner 180° to normal upright position.
Retighten four (4) nuts fastening oil burner assembly to
furnace.
• Beckett NX oil burner is not approved for downflow
installation when burner is equipped with burner cover.

5.3 Horizontal Installation

Maintain all clearances to combustibles. See Table 1. The furnace
may be installed in either of the horizontal positions, warm air
discharging left or warm air discharging right. Return air opening
may be located on either side or base panel of furnace.
• Rotate furnace 90° to desired position.
• Loosen four (4) nuts fastening oil burner assembly to
furnace. Rotate oil burner 90° in the opposite direction to
normal upright position. Retighten four (4) nuts fastening oil
burner assembly to furnace.
• Beckett AFG and Beckett NX oil burners are not approved for
horizontal installation when burner is equipped with burner
cover.
5.3a Non-Suspended Installation
• Installation on combustible floor requires 1 inch clearance.
• This can be accomplished by using non-combustible material
such as 1 inch thick channel iron or similar material.
N/A
• Support furnace to not allow twisting or sagging of cabinet.
5.3b Suspended Installation (See Figure 1)
• Suspend furnace by field fabricating a cradle of angle iron and
N/A
threaded rod.
• Secure furnace with 2 inch minimum slotted angle or
equivalent.
N/A
• Support furnace to not allow twisting or sagging of cabinet.
Closet
• Position supports to not interfere with accessing blower
compartment, burner and limit control.
