ELECTRICAL RATINGS:
Input Voltage:
18 to 30 VAC, 60 Hz
Current:
0.2 amp
Relay Contact Ratings:
Valve Relay:
1.5 amp @ 25 VAC 60 Hz 0.6 PF
Ignitor Relay: 6.0 amp @ 120 VAC 60 Hz-
resistive
Flame Current Requirements:
Minimum current to insure flame detection: 2 µA DC*
Maximum current for non-detection: 0.2 µA DC*
Maximum allowable leakage resistance: 100 M ohms
* Measured with a DC microammeter in series with the flame
probe lead
OPERATING TEMPERATURE RANGE:
-40° to 175°F (-40° to 80°C)
HUMIDITY RANGE:
To 95% relative humidity (non-condensing)
MOUNTING:
Surface mount or 4" x 4" junction box
GASES APPROVED:
Natural, Manufactured, Mixed, Liquid
Petroleum, and LP Gas Air Mixtures.
Replace control as unit –no user serviceable parts.
All wiring should be installed according to local and national
electrical codes and ordinances.
The control may be mounted in any orientation on a con-
venient surface using two #6 x 5/8” sheet metal screws. If
desired, control can 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 experience a minimum of vibra-
tion and remain below the maximum ambient temperature
rating of 175°F. The control is approved for minimum ambient
temperatures of -40°F.
Refer to the wiring diagrams and wiring table when connect-
ing the control to other components of the system.
UL approved 105°C rated 18 gauge minimum wire is recom
-
mended for all low voltage connections. UL approved 105°C
rated 16 gauge minimum wire is recommended for all line
voltage connections. Refer to table below for recommended
terminals to mate with those on the control.
After installation or replacement, follow appliance manufac
-
turer’s recommended installation/service instructions to insure
proper operation.
Do not use on circuits exceeding specified voltage.
Higher voltage will damage control and could cause
shock or fire hazard.
WARNING
!
To prevent electrical shock and/or equipment dam-
age, disconnect electric power to system at main fuse
or circuit breaker box until installation is complete.
Failure to earth ground the appliance or reversing the
neutral and hot wire connection to the line can cause
shock hazard.
Shut off main gas to heating system until installation
is complete.
Route and secure all wiring as far from flame as practical
to prevent fire and/or equipment damage.
