WARNING
!
ELECTRICAL SHOCK, FIRE OR EXPLOSION
HAZARD
Failure to follow safety warnings could result in
dangerous operation, serious injury, death or property
damage.
Improper servicing could result in dangerous operation,
serious injury, death or property damage.
- - Before servicing, disconnect all electrical power to
furnace.
- - When servicing controls, label all wires prior to
disconnection. Reconnect wires correctly.
- - Verify proper operation after servicing.
WARNING
!
ELECTRICAL SHOCK HAZARD
Failure to follow this warning could result in personal
injury or death.
Blower door switch opens 115- -v power to control. No
component operation can occur. Do not bypass or close
switch with blower door removed.
See Fig. 34 for field wiring diagram showing typical field 115- -v
wiring. Check all factory and field electrical connections for
tightness.
Field- -supplied wiring shall conform with the limitations of 63_F
(33_C) rise.
WARNING
!
ELECTRICAL SHOCK AND FIRE HAZARD
Failure to follow this warning could result in personal
injury, death, or property damage.
The cabinet MUST have an uninterrupted or unbroken
ground according to NEC NFPA 70- -2011 or local codes to
minimize personal injury if an electrical fault should occur.
In Canada, refer to Canadian Electrical Code CSA C22.1.
This may consist of electrical wire, conduit approved for
electrical ground or a listed, grounded power cord (where
permitted by local code) when installed in accordance with
existing electrical codes. Refer to the power cord
manufacturer's ratings for proper wire gauge. Do not use
gas piping as an electrical ground.
CAUTION
!
FURNACE MAY NOT OPERATE HAZARD
Failure to follow this caution may result in intermittent
furnace operation.
Furnace control must be grounded for proper operation or
else control will lock out. Control must remain grounded
through green/yellow wire routed to gas valve and manifold
bracket screw.
