Figure 3 – Downflow Installation

2.2.3 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 or KLASB0701DET can be used to ensure these clearances.
Refer to the instructions supplied with the base.
In cases where the return air enters through the floor, the floor return
base FRB-101 or KLARB0101DET can be installed as per the supplied
instructions.
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.

2.3 ELECTRICAL SYSTEM

CAUTION
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.
2.4 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, Figure 10 and Figure 11.
