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 appli- ance or reversing the neutral and hot wire con- nection 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

WIRING

The two terminals identified as MV connect to the 36E model gas valve. Both solenoids in the valve will be in parallel across these two terminals.

The TH terminal must be connected to the switched 24 volt wire from the thermostat (TH is the same as the W terminal on most low voltage thermostat systems).

The TR terminal is connected to the 24 volt transformer return. TR may be grounded either at the transformer or by a ground wire extended from the terminal TR (TR is the same as the C terminal on most low voltage thermostat systems).

The L1 terminal and IGN terminal are connected with a two-terminal connector on the ignitor leads.

The FP terminal is connected to the flame probe. Maxi- mum recommended wire length to the flame probe is 36 inches.

The GND terminal is a ground and return path for the flame sensor probe. GND must be reliably connected to the burner chassis ground.

NOTE

Replace 50E47 control as a unit - no user serviceable parts.

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

The 50E47 control may be mounted on any convenient surface using two #6 x 5/8 sheet metal screws. If desired, it is designed to be mounted on a 4" x 4" junction box using two #8-32 x 5/8" machine screws.

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 50E47 control to other components of the system.

UL approved, 105°C rated 18 gauge min., stranded, 2/64" thick insulation wire is recommended for all low voltage safety circuit connections. Refer to 50E47 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 50#47 specification sheet for rec- ommended terminals to mate with those on the control.

Following installation or replacement, follow appliance manufacturer's recommended installation/service instruc- tions to insure proper operation.
