MOUNTING AND WIRING

!WARNING

Do not use on circuits exceeding specified volt- age. Higher voltage will damage control and could cause shock or fire hazard.

!CAUTION

To prevent electrical shock and/or equipment damage, disconnect electric power to system at main fuse or circuit breaker box until installation is complete.

Failure to earth ground the appliance or revers- ing the neutral and hot wire connection to the line can cause shock hazard.

Shut off main gas to heating system until instal- lation is complete.

Route and secure all wiring as far from flame as practical to prevent fire and/or equipment damage.

INSTALLATION

NOTE

Replace 50A62 control as a unit - no user serviceable parts.

All wiring should be installed according to local and national electrical codes and ordinances.

The 50A62 control may be mounted only in a control box of a Lennox furnace.

The control must be secured to an area that will experi- ence a minimum of vibration and remain below the maxi- mum ambient temperature rating of 175°F. The control is approved for minimum ambient temperatures of -40°F.

Any orientation is acceptable.

Refer to the wiring diagram and wiring table when con- necting the 50A62 control to other components of the system.

UL approved, 105°C rated 18 gauge, stranded, 264” thick insulation wire is recommended for all low voltage safety circuit connections. Refer to 50A62 specification sheet for recommended terminals to mate with those on the control.

UL approved 105°C rated 16 gauge min., stranded, 464” thick insulation wire is recommended for all line voltage connections. Refer to 50A62 specification sheet for recommended terminals to mate with those on the control.

After installation or replacement, follow appliance manufacturer’s recommended installation or service instructions to ensure proper operation.
