LOW LIMIT OPERATION —On a temperature rise, with the adjustable differential atthe minimum setting of 10°F, the burner circuit (R-B) breaksand the circulator circuit (R-W) makes at the low limit setpoint. On a temperature drop of 10°F below the set point,the R-B circuit makes and the R-W circuit breaks.ADJUSTABLE DIFFERENTIAL —At any differential setting greater than 10°F, the R-Bmake temperature and R-W break temperature will remainthe same-control setting minus 10°F. The R-B break andR-W make temperature will be the set point temperatureplus the difference between the differential setting and 10°F.EXAMPLE: Set point of 140°F; differential set at 25°F. Ona temperature rise, R-B will break and R-W will make at155°F. On a temperature fall, R-B will make and R-W willbreak at 130°F.Set low limit indicator at the minimum temperaturerecommended for domestic hot water supply. This settingmust be at least 20°F below high limit setting to prevent oneswitch from locking out the other.Set the differential the desired number of degrees. 25°Fdifferential gives longest burner cycles.AQUASTAT SWITCHING ACTION WITHINL8148A CONTROLSThe switching action in the L8148A control has onesetting, the high limit. The switching relay is controlled bythe low voltage room thermostat. On a call for heat, the relaycontacts make to complete the line voltage circulator circuitand also the burner circuit if the boiler water temperature isbelow the high limit setting. The high limit switch shuts offthe burner if boiler water temperature exceeds the high limitsetting.Set the indicator at the desired shut-off temperature.52
Important Product Safety InformationRefractory Ceramic Fiber ProductWarning:This product contains refractory ceramic fibers (RCF). RCF has been classified asa possible human carcinogen. After this product is fired, RCF may, when exposedto extremely high temperature (>1800F), change into a known human carcinogen.When disturbed as a result of servicing or repair, RCF becomes airborne and, ifinhaled, may be hazardous to your health.AVOID Breathing Fiber Particulates and DustPrecautionary Measures:Do not remove or replace previously fired RCF (combustion chamber insulation,target walls, canopy gasket, flue cover gasket, etc.) or attempt any service orrepair work involving RCF without wearing the following protective gear:1. A National Institute for Occupational Safety and Health (NIOSH)approved respirator2. Long sleeved, loose fitting clothing3. Gloves4. Eye Protection• Take steps to assure adequate ventilation.• Wash all exposed body areas gently with soap and water after contact.• Wash work clothes separately from other laundry and rinse washingmachine after use to avoid contaminating other clothes.• Discard used RCF components by sealing in an air tight plastic bag.First Aid Procedures:• If contact with eyes: Flush with water for at least 15 minutes. Seekimmediate medical attention if irritation persists.• If contact with skin: Wash affected area gently with soap and water.Seek immediate medical attention if irritation persists.• If breathing difficulty develops: Leave the area and move to a locationwith clean fresh air. Seek immediate medical attention if breathingdifficulties persist.• Ingestion: Do not induce vomiting. Drink plenty of water. Seekimmediate medical attention.53
