MOST COMMON ADVANTAGEPLUS INSTALLATION CONCERNS
VENTING:
VENT LENGTH TOO LONG - OVER 85' (26 m)
VENTING NOT PITCHED PROPERLY - CONDENSATE BUILD UP IN VENT
EXHAUST GAS RE-CIRCULATION - VENT TERMINALS NOT USED, WRONG FITTINGS USED, SIGHT PROBLEMS
BUSH IN FRONT OF VENT TERMINAL
INSIDE CORNER OF BUILDING FOR VENT LOCATION
OVERHANG WITH VENT UNDERNEATH
COMPOUND ROOF PITCH, OR ABOVE ROOF FIRE WALL
ADDITIONAL FITTINGS INSTALLED INTO TERMINALS
VENT SIZED FROM 3" TO 4" BY USING BUSHINGS - INSTEAD OF REDUCING COUPLING OR REDUCING ELBOW
VENT CHANGED FROM 3" TO 4" - WITHOUT GOING REQUIRED 15' (4.6 m) ON BOTH INTAKE AND EXHAUST
VENTING NOT CLEANED AND GLUED TOGETHER FOR PRESSURE TIGHT JOINTS
INTAKE AIR CONTAINING EXHAUST FROM ANOTHER VENT OR APPLIANCE
GAS SUPPLY:
GAS PRESSURE TOO LOW - NEED 3.5" WC (0.87 kPa) GAS PRESSURE UP TO 14" WC (3.5 kPa) GAS PRESSURE
GAS METER TOO LOW IN CAPACITY
GAS REGULATOR NOT SIZED PROPERLY - TOO LOW IN CAPACITY
GAS PIPE TOO SMALL - 3/4" MINIMUM GAS SUPPLY SIZE
GAS REGULATOR TOO CLOSE TO APPLIANCE - NEED 10' OF PIPE FOR EVERY 200,000 BTU’S PER HOUR
GAS REGULATOR WITH LONG VENT OR BLEED VENT ORIFICE - REGULATOR SLOW TO RESPOND
GAS METER RESTRICTION, OR IN NEED OF REPAIR/REPLACEMENT
GAS SUPPLY PRESSURE DROPS BELOW 3.5" WC (0.87 kPa) WHEN APPLIANCE FIRES
ELECTRICAL:
APPLIANCE NOT GROUNDED
ELECTRICAL POLARITY REVERSED - FLAME WILL LIGHT BUT GO BACK OUT IN 4-6 SECONDS VOLTAGE TOO LOW OR TOO HIGH
APPLIANCE CYCLES, BUT NO IGNITION - REMOVE ANY CORROSION FROM SPARK ELECTRODE AND RECTIFIER. CHECK GAP
SPACING ON SPARK ELECTRODE. SHOULD BE 1/4" SPACING.
PLUMBING: DIELECTRIC UNIONS INSTALLED - RUSTY WATER

BURNER:
EXTREMEL
Y LOUD BANG ON IGNITION - BURNER FAILED OR END CAP OFF
RED BURNER DECK AS SEEN THROUGH VIEW PORT - GAS VALVE NEEDS ADJUSTMENT
GAS VALVE:
PUFFING ON IGNITION -
ADJUST

LOUD POP
ON IGNITION,
THEN RUNNING SMOOTH -
ADJUST

VE
HUFF
AND PUFF DURING OPERA
TION - ADJUST GAS VALVE
RUNNING GREAT BUT INTERMITTENTLY HUFFING OR POPPING - CHECK FOR RE-CIRCULATION UNDER VENTING
IT IS IMPORTANT TO NOTE FOR MAINTENANCE PURPOSES: THE THREAD ON THE END OF THIS GAS VALVE AND NIPPLE IS A
LEFT HAND THREAD.
SEALING ADVANTAGEPLUS AS PER N.S.F. STANDARD
NUMBER 5
TO SEAL THE BASE OF BOOSTER TO THE FLOOR TO
PREVENT SEE PAGE UNDERNEATH, PER N.S.F.
STANDARD #5 - APPLY A 3/8" BEAD OF RTV SILICONE
(AS SHOWN HERE), COMPLETELY AROUND TANK.
