Death or serious injury could occur if precautions are not
taken when maintaining this equipment. Position HEATER-
OFF-FAN switch to OFF, remove power cable plug from
POWER RECEPTACLE, and ground capacitors C1 and C2
prior to gaining access to heater compartments. Terminals
of capacitors are accessible at end cover of combustion
blower. Always disconnect power cable before making con-
tinuity tests or before repairing heater. Always have
another person standing by who is trained in electric shock
first aid.
Allow sufficient time for heater to cool to room tempera-
ture before gaining access to heater compartments.
1. Check butt connectors (1) for security.
Replace loose butt connectors. Always use new butt
connectors after disconnecting wire.
Be sure 1/4 inch (6.35 mm) of good wire is stripped before
installation.
2. Check ring tongue terminal (2) and ring terminals (3) for security, damage, and burning. Replace
loose or damaged terminal.
If damaged terminal is still firmly crimped to wire, cut wire close to
terminal. Strip 3/8 inch (9.53 mm) of insulation and crimp on new terminal.
3. Check quick disconnect terminals (4) for security, damage, and burning. Be sure terminal makes
firm contact with mating terminal.
Replace loose, damaged, or poorly fitting terminals. If
damaged terminal is still firmly crimped to wire, cut wire close to terminal. Strip 3/8 inch
(9.53 mm) of insulation and crimp on new terminal.
