R4795A

SPECIFICATIONS

TERMINAL RATINGS:

Terminal	Load		Rating
3	Pilot Valve	125	VA pilot duty.
	Intermittent Ignitiona	360	VA.
4	Interrupted Ignition	360	VA.
5	Main Fuel Valve(s)	125	VA pilot duty, or 25 VA pilot duty plus one or more motorized
		valves with total rating up to 400 VA opening, 200 VA holding.
6-7	Airflow Switch	0.6A at 30 Vdc.
8	Fan or Burner Motor	9.8A full load, 58.8A locked rotor (inrush) at 120 Vac. 4.9A full
		load, 29.4A locked rotor (inrush at 220 and 240 Vac.
Isolated Spdt Alarm	Alarm	3A at 24 volts, or 1A at 120 volts, in a suitable wiring enclosure.
Terminals (Optional)

aWhen ignition is connected to terminal 3, terminal 4 cannot be used.

NOTE: Allowable inrush can be up to ten times the pilot duty rating.

Example:

Pilot duty rating = 125 VA.

At 120V, running current is 125/120 = 1.05A. Maximum allowable inrush is 10 times 1.05 = 10.5A.

DIMENSIONS (Includes Cover and Subbase): Approxi- mately 5 x 5 x 5 in. (127 x 127 x 127 mm).

MOUNTING: Q270A1024 Subbase. Ordered separately.
