Page 30 r -OVER Pilot, Gas and Air Control '� Descriptions �9f�yEARs�ye N�ESEtg Gas-Fired Unit Heaters PILOT IGNITION SYSTEMS • MANUAL PILOT: Manual match-lit pilot with 100% shut-off. Pilot remains on 100% of time until pilot gas flow is shut off. • INTERMITTENT SPARK PILOT:Automatic lighting of pilot with an electronic spark on a call for heat. Pilot gas flow is shut off between heat cycles. A.G.A. certified for use with natural and propane gas with outdoor units; A.G.A. certified for use with natural gas only on indoor units; C.G.A. approved for use with natural gas only on indoor and outdoor units. • INTERMITTENT SPARK PILOT WITH TIMED LOCKOUT: Automatic lighting of pilot with an electronic spark on a call for heat. Pilot gas flow is shut off between heat cycles. Lockout device stops gas flow to the pilot if the pilot fails to light in 120 seconds. Reset of lockout requires manual interruption of the thermostat circuit. A.G.A.certified and C.G.A. approved for use with natural or propane gas on indoor and outdoor applications. GAS CONTROL SYSTEMS • SINGLE-STAGE: Single-stage gas valve which cycles on at 100% fire on a call for heat. • TWO-STAGE: Two-stage gas valve which fires at 100% or 50%, as required by remote two-stage thermostat. AIR CONTROL SYSTEMS • AIR RECIRCULATION KIT(SINGLE-STAGE UNITS ONLY): First stage control of thermostat energizes unit heater fan to recir- culate warm stratified ceiling air. Second stage control of thermostat opens single-stage gas valve. Kit includes relay and two-stage thermostat (40°-9O°F) shipped separately. • SPECIAL AIR RECIRCULATION KIT (SINGLE-STAGE UNITS ONLY): Same as the basic kit, with the addition of a manual summer switch on thermostat for summer fan operation.
