CONFIGURATIONS
1.2.1.
Upflow Installation
The return air opening may be located on either side of the furnace.
Care should be taken not to damage the wires inside, while cutting
the opening. Install the filter rack supplied with the unit according to
the instructions provided with it. It is also recommended to install the
blower door before handling or moving the unit. Refer to figure 2 for
additional details.

Upflow installation
1.2.2.
Downflow Installation
When the furnace is installed in the downflow position on a
combustible floor, the clearances from combustibles must be
adhered to. The downflow base DFB-102 can be used to ensure
these clearances. Refer to Figure 3 and the installation instructions
provided with the base.
The burner must always be installed in the same manner, regardless
of the discharge position of the furnace. Refer to Figure 3 for
additional details.
The protection plate (B03789) must be installed on the plastic cover
of the Beckett NX burner to protect it from vent.
Figure 3: Downflow installation
1.2.3.
Horizontal Installation
When the furnace is installed in the horizontal position, either
suspended or on a combustible floor with a choice of right or left
discharge, the clearances from combustible material must be
adhered to. If the unit is installed on a combustible floor, the
horizontal floor base HFB-101 can be used to ensure these
clearances. Refer to the instructions supplied with the base.
The burner must always be installed in the same manner, regardless
of the discharge position of the furnace. Refer to Figure 4 for
additional details.

ELECTRICAL SYSTEM
The exterior of the unit must have an
uninterrupted ground to minimize the risk of
bodily harm, if ever an electrical problem
develops. A green ground screw is supplied with
the control box for that purpose.
The appliance must be installed in accordance with the current
ANSI/NFPA 70 National Electrical Code, CSA C22.1 Canadian
Electrical Code Part 1 and/or local codes.
The control system depends on the correct polarity of the power
supply. Connect “HOT” wire (H) and “NEUTRAL” wire (N) as shown
in figures 10 and 11.
A separate line voltage supply should be used, with fused
disconnect switch or circuit breaker, between the main power panel
and the unit.
Only copper wire may be used for the 115V circuit on this unit. If
wires need to be changed, the replacements must have the same
temperature resistance as the originals.
1.4.
INSTALLATION OF THE THERMOSTAT
A thermostat must be installed to control the temperature of the area
to be heated. Follow the instructions supplied with the thermostat.
Also refer to the wiring diagrams provided with the heating/air
conditioning unit. The connections must be made as indicated on the
following diagrams and the wiring diagrams, figures 10 and 11.
