Adams Condensing Oil-Fired Furnace - Manual (Page 13)

VII. ELECTRICAL CONNECTIONS
! WARNING
HIGH VOLTAGEI
To avoid the risk of electrical shock,
wiring to the unit must be polarized
and grounded.
! WARNING
HIGH VOLTAGEI
To avoid personal Injury or death due
to electrical shock, disconnect
electrical power before servicing or
changing any electrical wiring.
! CAUTION
Label all wires prior to
disconnection when servicing
controls. Wiring errors can
cause improper and dangerous
operation. Verify proper
operation after servicing.
wiring Harness
The wiring harness is an integral part of this
furnace. Field alteration to comply with
electrical codes should not be required.
Wires are color-coded for identification
purposes. Refer to the wiring diagram for
wire routings. If any of the original wire as
supplied with the furnace must be replaced,
it must be replaced with wiring material
having a temperature rating of at least 105
degrees C. Any replacement wring must be
copper conductor.
115 Volt Line Connections
Before proceeding with electrical
connections, ensure that the supply voltage,
frequency, and phase correspond to that
specified on the unit rating plate. Power
supply to the furnace must be N.E.C. Class
1, and must comply wth all applicable
codes, and/or The Canadian Electric Code
CSA C22.1.
Use a separate fused branch electrical
circuit containing properly sized wire,
minimum 12 gauge, and fuse or circuit
breaker.
The furnace must be electrically grounded
in accordance with local codes or, in their
absence, with the latest edition of;
The National Electric Code, ANSI NFPA 70.
The fuse or circuit breaker must be sized in
accordance with the maximum over-current
protection specified on the unit rating plate.
An electrical disconnect must be provided
at the furnace location.
NOTE: Line polarity must be observed
when making field connections.
! WARNING
THE DRAIN TRAP MUST VBE
MOUNTED ON THE OPPOSITE SIDE
OF THE UNIT FROM THE JUNCTION
BOX. THIS WILL REDUCE THE RISK
OF WATER REACHING THE JUNCTION
BOX IN THE EVENT OF A BLOCKED
DRAIN CONDITION.
Connect hot, neutral, and ground wires as
shown in the wiring diagram located on the
unit's blower door. Line polarity must be
observed when making field connections.
Line voltage connections can be made
through either the right or left side panel.
The furnace is shipped configured for a right
side electrical connection with the junction
box located inside the blower compartment.
To make electrical connections through the
opposite side of the furnace, the junction
box must be relocated to the other side of
the blower compartment prior to making
electrical connections.
NOTE: Wire routing must not interfere with
circulator blower operation, filter removal, or
routine maintenance.
! WARNING
EDGES OF SHEET METAL HOLES
MAY BE SHARP. USE GLOVES AS A
PRECAUTION WHEN REMOVING HOLE
PLUGS.
