CONTRACTOR SHALL REVIEW SEQUENCES PRIOR TO PROGRAMMING AND SUGGEST MODIFICATIONS WHERE REQUIRED TO ACHIEVE THE DESIGN INTENT. CONTRACTOR MAY ALSO SUGGEST MODIFICATIONS TO IMPROVE PERFORMANCE AND STABILITY OR TO SIMPLIFY OR REORGANIZE LOGIC IN A MANNER THAT PROVIDES EQUAL
OR BETTER PERFORMANCE.
INCLUDE COSTS FOR MINOR PROGRAM MODIFICATIONS IF REQUIRED TO PROVIDE PROPER PERFORMANCE OF
THE SYSTEM.
UNLESS OTHERWISE INDICATED IN SOO, CONTROL LOOPS SHALL BE ENABLED AND DISABLED BASED ON THE
STATUS OF THE SYSTEM BEING CONTROLLED TO PREVENT WIND-UP.
THE TERM “PROVEN” (I.E. “PROVEN ON” / “PROVEN OFF”) SHALL MEAN THAT THE EQUIPMENT’S DI STATUS POINT
MATCHES THE STATE SET BY THE EQUIPMENT’S DO COMMAND POINT.
THE TERM “PID LOOP” OR “CONTROL LOOP” IS USED GENERICALLY FOR ALL CONTROL LOOPS AND SHALL NOT BE INTERPRETED AS REQUIRING PROPORTIONAL PLUS INTEGRAL PLUS DERIVATIVE GAINS ON ALL LOOPS. UNLESS SPECIFICALLY INDICATED OTHERWISE, DO NOT USE THE DERIVATIVE TERM ON ANY LOOPS UNLESS FIELD
TUNING IS NOT POSSIBLE WITHOUT IT.
ALL SET-POINTS, TIMERS, DEAD-BANDS, ETC. LISTED IN SEQUENCES SHALL BE CAPABLE OF BEING ADJUSTED BY THE OPERATOR WITHOUT HAVING TO ACCESS PROGRAMMING WHETHER INDICATED AS ADJUSTABLE IN SEQUENCES OR NOT. SOFTWARE (VIRTUAL) POINTS SHALL BE USED FOR THESE SET-POINTS. FIXED SCALAR NUMBERS SHALL NOT BE IMBEDDED IN PROGRAMS UNLESS THE VALUE WILL NEVER NEED TO BE ADJUSTED. PID GAINS SHALL BE ONLY ACCESSIBLE BY AUTOMATION TECHNICIAN AND HIDDEN FROM EVERYDAY OPERATOR.
VALUES FOR ALL POINTS, INCLUDING REAL (HARDWARE) POINTS USED IN CONTROL SEQUENCES SHALL BE CAPABLE OF BEING OVERRIDDEN BY THE USER (E.G. FOR TESTING AND COMMISSIONING). IF HARDWARE DESIGN PREVENTS THIS FOR HARDWARE POINTS, THEY SHALL BE EQUATED TO A SOFTWARE POINT AND THE SOFTWARE POINT SHALL BE USED IN ALL SEQUENCES. EXCEPTION: NOT REQUIRED FOR EMERGENCY
GENERATOR AND ELECTRICAL READ ONLY POINTS.
MOTOR SPEED CONTROL SET-POINTS:
MINIMUM SPEED SET-POINTS FOR ALL VFD-DRIVEN AND EC MOTOR EQUIPMENT SHALL BE THE GREATER OF
EITHER 6 HZ OR THE MINIMUM SPEED REQUIRED TO AVOID STALLING THE DEVICE SERVED.
MINIMUM SPEED FOR EACH PIECE OF EQUIPMENT SHALL BE STORED IN A SINGLE SOFTWARE POINT THAT SHALL BE USED IN PROGRAMMING (SUCH AS PID LOOP OUTPUT RANGE) AND ITS VALUE SHALL BE ASSIGNED TO THE MINIMUM SPEED SET-POINT STORED IN THE VFD VIA THE DRIVE NETWORK INTERFACE. IN THIS WAY THERE IS ONLY ONE MINIMUM SET-POINT, RATHER THAN SET-POINTS BOTH IN THE DRIVE AND IN THE
SOFTWARE WHICH COULD DIFFER.
MAXIMUM SPEED SET-POINT FOR MOTOR DRIVEN EQUIPMENT SHALL BE DETERMINED BY THE MAXIMUM ALLOWABLE OPERATIONAL SPEED BY THE MOTOR AND OR DRIVEN DEVICE MANUFACTURER. THE SPEED CONTROL SHALL NOT LIMIT THE MAXIMUM RUNNING SPEED TO 60 Hz UNLESS THAT IS THE MAXIMUM SPEED
ALLOWABLE BY THE MOTOR, FAN, OR PUMP.

GAS DETECTION SYSTEM (GDS)
A. GENERAL
THE GAS DETECTION SYSTEM CONSISTS OF A GAS DETECTION PANEL, GAS ANALYSIS INSTRUMENTS, AUDIO- VISUAL ALARM DEVICES, WIRING/CONDUIT, ASSOCIATED POWER DISTRIBUTION, AND CONNECTIONS TO
FACILITY CONTROLS PANELS AND EQUIPMENT.
THE GAS DETECTION SYSTEM SHALL MONITOR METHANE (CH4) GAS LEVELS AT THE CEILING AND CARBON MONOXIDE (CO) GAS LEVELS IN THE BREATHING ZONE. LEVELS MEASURED THAT OCCUR OUTSIDE OF NIOSH AND VHA SETPOINTS WILL BE ALARMED AND THE FOLLOWING SEQUENCES SHALL BE IMPLEMENTED AND
FOLLOWED.
B. EMERGENCY EQUIPMENT SHUTDOWN CIRCUIT
THE GDS SHALL BE DIRECTLY CONNECTED, THROUGH HARDWIRED SIGNAL, TO ALL BOILERS, GAS SHUTOFF VALVE, OIL SHUTOFF VALVE, OIL PUMP SHUTDOWN, AND VENTILATION EQUIPMENT, LOCATED IN THE ALARM ZONE, THROUGH DRY CONTACTS ON THE REMOTE EQUIPMENT. THE ALARM CIRCUIT SHALL BE POWERED IN A "NORMAL" STATE PER THE DETAIL PROVIDED ON THE DETAIL SHEET. LOSS OF POWER TO THE GDS OR AN ALARM STATE SHALL OPEN THE MONITORED CONTACTS ON THE GDS, THUS BREAKING THE CIRCUIT. AN "ALARM" STATE SHALL DISABLE ALL FUEL BURNING EQUIPMENT IN THE ZONE BY DISABLING THE HARDWIRED
LOOP.
C. SYSTEM ENABLE
THE SYSTEM SHALL ALWAYS BE ENABLED. LOSS OF AN ENABLED STATUS SHALL RESULT IN AN ALARM
SIGNAL TO THE BAS, THE FACP, AND DISABLING OF THE FUEL BURNING APPLIANCES.
D. NORMAL STATUS
THE GDS SHALL SEQUENTIALLY TAKE, ANALYZE, AND REPORT GAS CONDITIONS AT EACH SAMPLING POINT
IDENTIFIED IN THE DRAWINGS:
ZONE 1: BOILER ROOM (102) & MEZZANINE
ZONE 2: CONTROL ROOM (104)
ZONE 3: GAS BOOSTER ROOM (114)
ZONE 4: PROPANE ROOM (113)
THE FUEL BURNING APPLIANCE CIRCUITS SHALL BE ENABLED AND ALL FUEL BURNING EQUIPMENT SHALL BE ALLOWED TO OPERATE NORMALLY. FUEL BURNING EQUIPMENT INCLUDE BOILER NOS. 1, 2, AND 3 ONLY.
E. ALARMS/EMERGENCY OPERATION
FAULT - STATUS NOTIFICATION TO BAS TO INDICATE MAINTENANCE REQUIREMENT OR SYSTEM INSPECTION
REQUIREMENT. GDS CONTINUES TO OPERATE.
SYSTEM FAILURE - STATUS NOTIFICATION TO BAS TO INDICATE INORABILITY OF THE SYSTEM. ENABLE VENTILATION EQUIPMENT IN ALL ZONES, PROVIDE ALARM TO BAS, ACTIVATE ZONE ALARM EQUIPMENT.
CARBON MONOXIDE MONITORING AND ALARM
CARBON MONOXIDE IS PRODUCED BY COMBUSTION. CO WILL BE PRESENT IN AND AROUND THE BOILER BURNER, FLUE, AS WELL AS POTENTIALLY THE VALVE VAULT TO THE REAR OF BOILER 10-BLR-1. IT IS A
HEAVIER THAN AIR GAS.
ALL ALARM LEVELS LISTED HERE ARE BASED ON INDUSTRY ACCEPTED STANDARDS FOR SAFETY OF LIFE AND HEALTH. IN GENERAL, THE NATIONAL INSTITUTE FOR OCCUPATIONAL SAFETY AND HEALTH
(NIOSH) AND THE OCCUPATIONAL SAFETY AND HEALTH ADMINSTRATION (OSHA) PROVIDE
RECCOMENDATIONS FOR ALARM LEVELS AND EXPOSURE LIMITS. COORDINATE FINAL SETPOINTS WITH THE VHA LIFE SAFETY TEAM FOR THIS STATION. COORDINATE WITH THE COR TO SET UP A MEETING TO
CONFIRM THE LEVELS FOR FINAL ACCEPTANCE.
AMERICAN CONFERENCE OF GOVERNMENTAL INDUSTRIAL HYGIENISTS (ACGIH), TLV-TWA LISTS 25
PPM AS THE MAXIMUM ALLOWABLE CONCENTRATION FOR A WORKER'S CONTINUOUS EXPOSURE
IN ANY EIGHT HOUR PERIOD. THIS IS USED AS THE LOW ALARM SETPOINT FOR THIS DESIGN.
NIOSH LISTS 200 PPM AS THE MAXIMUM ALLOWABLE CONCENTRATION FOR SHORT TERM
EXPOSURE AT A 15-MINUTE MAXIMUM EXPOSURE LEVEL. ADDING A SAFETY MARGIN FOR
INCREASING CONCENTRATION IN THE SPACE, 100 PPM SHALL BE USED AS THE HIGH ALARM
SETPOINT FOR THIS DESIGN.
LOW ALARM, 25 PPM (CO) - PROVIDE ALARM TO THE BAS. IDENTIFY ALARM ZONE. BAS TO OVERRIDE VENTILATION SYSTEM TO MAXIMUM SPEED SIGNAL IF SYSTEM IS ON, OR ENABLE VENTILATION SYSTEM
AND OVERRIDE SPEED CONTROL TO MAXIMUM SPEED IF SYSTEM IS OFF.
HIGH ALARM, 100 PPM (CO) - LOW ALARM PLUS DISABLE FUEL BURNING APPLIANCE CIRCUIT (BOILER EPO
CIRCUIT), PROVIDE ALARM TO THE BAS, IDENTIFY ALARM ZONE.
METHANE (CH4) MONITORING AND ALARM
METHANE MAY BE LEAKED FROM GAS SYSTEM EQUIPMENT AND PIPING AS WELL AS THE GAS PIPING IN
AND AROUND THE BOILERS. METHANE IS A LIGHTER THAN AIR GAS.
THE FUEL GAS DETECTION SYSTEM SHALL BE INSTALLED, TESTED, AND COMISSIONED IN COMPLIANCE WITH ALL VHA STANDARDS AND CODES AS WELL AS NFPA 715, STANDARD FOR THE INSTALLATION OF
FUEL GASES DETECTION AND WARNING EQUIPMENT.
ALL ALARM LEVELS LISTED HERE ARE BASED ON INDUSTRY ACCEPTED STANDARDS FOR SAFETY OF LIFE AND HEALTH. IN GENERAL, THE NATIONAL INSTITUTE FOR OCCUPATIONAL SAFETY AND HEALTH
(NIOSH) AND THE OCCUPATIONAL SAFETY AND HEALTH ADMINSTRATION (OSHA) PROVIDE
RECCOMENDATIONS FOR ALARM LEVELS AND EXPOSURE LIMITS. COORDINATE FINAL SETPOINTS WITH THE VHA LIFE SAFETY TEAM FOR THIS STATION. COORDINATE WITH THE COR TO SET UP A MEETING TO

SEQUENCE OF OPERATION
HOT WATER BOILER NOS. 1, 2, AND 3
A. GENERAL
THREE NEW HEATING HOT WATER BOILERS (BLR-01, 02, AND 03) WILL SUPPORT THE LOCH RAVEN STATIONS' PEAK AND FUTURE HEATING HOT WATER LOAD. THE NOMINAL CAPACITY OF EACH GENERATOR IS AS FOLLOWS:
BOILER RATED OUTPUT FLOW
BLR-01 6.7 MILLION BTUH 670 GPM
BLR-02 6.7 MILLION BTUH 670 GPM
BLR-03 6.7 MILLION BTUH 670 GPM
THE HEATING PLANT AT LOCH RAVEN VAMC IS DESIGNED AS A PRIMARY/SECONDARY LOOP FLOW SYSTEM. THE PRIMARY LOOP INCLUDES THE BOILERS, CIRCULATING PUMPS (PHWPS), NEUTRAL BRIDGE/DECOUPLER, PIPING, VALVES, AND SPECIALTIES. THE SECONDARY LOOP INCLUDES THE DISTRIBUTION PUMPS (SHWPS), STATION BUILDING SYSTEMS, SUPPLY AND RETURN PIPING, VALVES, AND SPECIALTIES AND ALSO INCLUDES THE NEUTRAL BRIDGE/DECOUPLER. THESE
SYSTEMS OPERATE INDEPENDENT OF EACH OTHER.
A NEUTRAL BRIDGE/DECOUPLER IS LOCATED IN THE PLANT, HYDRAULICALLY SITUATED AT THE INTERFACE OF THE PRIMARY AND SECONDARY FLOW LOOPS. ITS PURPOSE IS TO PERMIT THE SECONDARY DISTRIBUTION AND PRIMARY CIRCULATION SYSTEMS TO OPERATE AT DIFFERENT LOAD BLOCKS AND FLOW RATES. FLOW IN THE SECONDARY LOOP IS
VARIABLE AND FLOW IN THE PRIMARY LOOP IS CONSTANT WITH EACH OPERATING BOILER.
THE BOILERS ARE INTENDED TO OPERATE AUTOMATICALLY WHEN STARTED. HOWEVER, IT IS NOT INTENDED THAT THE PLANT BAS BE ABLE AUTOMATICALLY START OR STOP GENERATORS. THE PLANT OPERATOR MUST INITIATE THE ACTUAL
START/RESTART/STOP FUNCTIONS.
THE PRIMARY AND SECONDARY PUMPS OPERATE EACH AS A BANK OF PUMPS. THE PUMPS AND BOILERS CAN BE
OPERATED RELATIVE TO HOURS OF OPERATION IN AN EFFORT TO BALANCE THE HOURS.
REFER TO THE “HEATING PLANT OPERATIONAL SEQUENCE MATRIX”, LOCATED ON THIS SHEET, FOR PLANT LOAD VERSUS EQUIPMENT OPERATION. SEVERAL OPERATIONAL SCENARIOS ARE AVAILABLE FOR THE DIFFERENT CAPACITY BLOCKS.
EQUIPMENT OPERATION FOR EACH LOAD BLOCK SHALL BE SELECTED BY THE PLANT OPERATORS. THE MATRIX SHALL BE GRAPHICALLY REPRESENTED, FOR OPERATOR REFERENCE, ON THE OPERATORS TERMINAL LOCATED IN THE CONTROL
ROOM.
SEPARATE HTHW DISTRIBUTION PUMPS MOVE WATER THROUGH A SECONDARY PIPING SYSTEM FROM THE PLANT TO OTHER BUILDINGS ON THE STATION. SEE THE OPERATING SEQUENCES FOR THE CIRCULATION PUMPS AND DISTRIBUTION
PUMPS FOR DETAILS.
THE FOLLOWING DESCRIPTIONS ARE FOR BOILER, BLR-01. OPERATION AND CONTROLS FOR ALL THREE UNITS SHALL BE
IDENTICAL.
IF THE HEATING HOT WATER RETURN TEMPERATURE, AS SENSED BY TE-1XX/TT-1XX, IS LESS THAN 180 F (ADJUSTABLE SET POINT) AND THE OPERATING BOILERS ARE ALL FIRING AT 100 PERCENT CAPACITY, THE BAS SHALL PROMPT THE
OPERATOR TO START ANOTHER BOILER.
INTERLOCKS
B. PERMISSIVE INTERLOCKS NECESSARY TO OPERATE HTHWG :
NEITHER THE EXPANSION TANK NOR THE DUMP TANK SHALL BE IN A STATE OF ALARM.
SINCE THE BOILER HAS THE POTENTIAL TO OPERATE WITH ANY CIRCULATION PUMP, NO INTERLOCK IS REQUIRED FOR PUMP OPERATION. HOWEVER, FE-1XX/FT-1XX SHALL INDICATE THAT FLOW THROUGH THE BOILER IS GREATER THAN 85
PERCENT OF FULL FLOW.
THE TEMPERATURE OF THE WATER AT THE OUTLET OF THE BOILER SHALL BE 180F OR HIGHER AS SENSED BY TE -1XX/TT-1XXB. THE BAS SHALL BE EQUIPPED WITH A MANUAL OVERRIDE OF THIS INTERLOCK FOR COLD START OF THE
PLANT WHEN OTHER BOILERS ARE OPERATING).
ADEQUATE NATURAL GAS PRESSURE SHALL BE PROVIDED AND MONITORED BY TE -1XXB/TT -1XXB AT 1.5 PSIG MINIMUM.
IF FUEL (DIESEL) OIL IS SELECTED AS THE OPERATING FUEL, ADEQUATE OIL PRESSURE SHALL BE PROVEN BY PSL-3XX AT
100 PSIG MINIMUM.
IF FUEL (DIESEL) OIL IS SELECTED AS THE OPERATING FUEL, ADEQUATE COMPRESSED AIR PRESSURE (ATOMIZING AIR) SHALL BE PROVEN BY PT -5XX AT 125 PSIG MINIMUM. ATOMIZING AIR IS PROVIDED BY ON-BOARD COMPRESSORS
LOCATED AT EACH BOILER.
TO OPERATE ANY COMBINATION OF HEATING HOT WATER BOILERS WITH A COMBINED NOMINAL CAPACITY LESS THAN OR EQUAL TO 6.7 MMBTUH, MUA-01 SHALL BE OPERATING AT ITS STAGE 1 SPEED (XX,XXX CFM). PERMISSIVE SHALL INCLUDE
CONFIRMATION OF AIRFLOW FROM THE AIRFLOW MONITOR ON MUA-01.
TO OPERATE ANY COMBINATION OF HEATING HOT WATER BOILERS WITH A COMBINED NOMINAL CAPACITY LESS THAN OR EQUAL TO 13.4 MMBTUH, MUA-01 SHALL BE OPERATING AT ITS STAGE 2 SPEED (XX,XXX CFM). PERMISSIVE SHALL INCLUDE
CONFIRMATION OF AIRFLOW FROM THE AIRFLOW MONITOR ON MUA-01.
IF MUA-01 EXPERIENCES A FAILURE AND IS UNABLE TO SATISFY AIR FLOW INTERLOCKS, THE OPERATOR SHALL SWITCH INTERLOCKS TO BACK-UP LOUVER IAL-01. THIS LOUVER SHALL REMAIN CLOSED UNTIL REQUIRED FOR BACK-UP
COMBUSTION AIR FLOW.
C. SAFETY INTERLOCKS: THE FOLLOWING INTERLOCKS SHALL STOP THE BOILER(S) .
THE EXPANSION TANK (HHWET-01) PRESSURE DROPS TO 40 PSIG (PSL -131 SEE PRESSURIZATION SYSTEM SEQUENCE).
INTERLOCK AND ALARM.
THE EXPANSION TANK (HHWET-01) PRESSURE RISES TO 100 PSIG (PSL-131 SEE PRESSURIZATION SYSTEM SEQUENCE).
INTERLOCK AND ALARM.
FLOW RATE SENSED BY FE -XXX/FT -XXX DROPS TO 80 PERCENT OF UNIT SET POINT. INTERLOCK AND ALARM.
D. TO PLACE A COLD BOILER INTO A “STAND-BY” CONDITION
THE OPERATOR SHALL SELECT BOILER TO BE PLACED IN “STAND-BY” FROM THE OPERATOR TERMINAL DISPLAY.
THE BAS SHALL PROMPT THE OPERATOR TO EXECUTE THE FOLLOWING PRE-START MANUAL STEPS:
OPEN 2-INCH BYPASS VALVES ON BOILER INLET AND OUTLET.
OPEN 2-INCH ISOLATION VALVES ON WARMUP LINE FROM BOILER CIRCULATION PUMPS.
MODULATING CONTROL VALVE FV-10XA SHALL BE FULLY CLOSED AND THE CONTROL LOOP WITH FE-10X/FT-10X INACTIVE.
OPEN 2-INCH BYPASS VALVES ON BOILER INLET AND OUTLET.
OPEN 2-INCH ISOLATION VALVES ON WARMUP LINE FROM BOILER CIRCULATION PUMPS.
MODULATING CONTROL VALVE FV-10XA AND FV-10XB SHALL BE FULLY CLOSED AND THE CONTROL LOOP WITH
FE-10X/FT-10X INACTIVE.
WHEN THE FLOW HAS BEEN PROVEN BY CURRENT SWITCH PDS-XXX, THE BAS SHALL INDICATE THAT BOILER IS
"WARMING".
WHEN THE TEMPERATURE OF THE WATER LEAVING THE BOILER RISES TO 160 DEG F (TE -10XB)/ TT -10XB WITH ADJUSTABLE SET POINT), THE BAS SHALL INDICATE THAT HTHWG-4 IS "STAND-BY".

TO START A BOILER (WHEN OTHER BOILERS ARE OPERATING )
TO START A BOILER THE UNIT SHALL BE IN A "STAND-BY" CONDITION WITH THE LEAVING WATER TEMPERATURE AT 160 DEG F OR
WARMER.
THE BAS SHALL NOT BE CAPABLE OF PHYSICALLY STARTING A BOILER AUTOMATICALLY. BURNER OPERATION (FIRING) AT A
BOILER SHALL BE MANUALLY INITIATED FROM THE UNIT'S LOCAL CONTROL PANEL.
TO BEGIN FIRING A BOILER, THE PLANT OPERATOR SHALL SELECT THE RUN COMMAND VIA THE BAS OPERATOR TERMINAL. THIS
COMMAND SHALL INITIATE A PRE-START SEQUENCE AS FOLLOWS:
THE BAS SHALL PROMPT THE OPERATOR TO SELECT THE FUEL TO BURN. NATURAL GAS SHALL BE THE DEFAULT FUEL.
IF FUEL (DIESEL) OIL IS SELECTED, THE BAS SHALL INITIATE THE PUMP SELECTION SEQUENCE FOR FUEL OIL PUMPS (SEE
FUEL OIL PUMP CONTROL SEQUENCE).
THE BAS SHALL PROMPT THE PLANT OPERATOR TO START THE ASSOCIATED CIRCULATING PUMP. THE OPERATOR SHALL START THE PUMP VIA THE BAS OPERATOR TERMINAL (SEE PHWP CONTROL SEQUENCE). THE BAS SHALL OPEN FCV-XXXA TO 100%. A PERMISSIVE CONTACT SHALL BE MADE WHEN THE SIGNAL FROM FE -10X/FT10X INDICATES THAT FLOW TO THE HTHWG IS GREATER THAN 85 PERCENT OF THE RATED FLOW. THE BAS SHALL ACTIVATE THE CONTROL LOOP FOR FCV-XXXA SO THAT THE VALVE MODULATES IN RESPONSE TO THE SIGNAL FROM FE-XXX/FT -XXX ONCE THE PERMISSIVE IS ACTIVATED.
THE BAS SHALL PROMPT THE PLANT OPERATOR TO START THE MAKEUP AIR UNIT OR INCREASE THE FAN SPEED (SEE PLANT SEQUENCE MATRIX). HVAC EQUIPMENT SEQUENCES SHALL BE PER DRAWINGS. OPERATION PRIORITY SHALL BE ADJUSTED
PER THE MATRIX.
WHEN THE PERMISSIVE INTERLOCKS ARE MET, THE BAS SHALL INDICATE THAT THE UNIT IS “READY” TO START AND SHALL
MAKE THE RUN PERMISSIVE CONTACT TO THE LOCAL UNIT CONTROL PANEL.
THE OPERATOR SHALL START THE BOILER FROM THE UNIT'S LOCAL CONTROL PANEL UNDER "MANUAL" CONTROL. AFTER THE MANUFACTURER'S RECOMMENDED TIME ELAPSE, THE OPERATOR SHALL ADJUST THE UNIT CONTROLS TO "AUTOMATIC".
AUTOMATIC CONTROLS (FURNISHED WITH THE BOILERS )
SHALL MAINTAIN FLAME SAFETY (BURNER MANAGEMENT SYSTEM) AND REGULATE BURNER FIRING (COMBUSTION CONTROL
SYSTEM) TO MAINTAIN THE OUTLET WATER TEMPERATURE AT 180 DEG F (ADJUSTABLE).
WHEN THE BOILER BEGINS FIRING, THE BAS SHALL ACTIVATE THE CONTROL LOOP FOR FCV-XXXA SO THAT THE VALVE
MODULATES IN RESPONSE TO THE SIGNAL FROM FE-XXX/FT -XXX.
AFTER FCV-XXXA IS ACTIVE, THE BAS SHALL CLOSE FCV-XXXB. THE ACTUATION RATE SHALL BE RETARDED TO SLOW VALVE CLOSING. FCV-XXXA SHALL TRANSITION FROM FULLY OPEN TO FULLY CLOSED IN ABOUT 30 SECONDS.
