NOTES:
1.
INSTALL OVERCURRENT PROTECTION IN ACCORDANCE WITH AUTHORITY HAVING JURISDICTION
OR, IN THE ABSENCE OF SUCH REQUIREMENTS, FOLLOW THE NATIONAL ELECTRIC CODE, NFPA 70,
AND/OR CSA C22.1 ELECTRICAL CODE.
DO NOT
PROVIDE OVERCURRENT PROTECTION GREATER
THAN 15 AMPERES.
2.
IF ANY OF THE ORIGINAL WIRE SUPPLIED WITH THE APPLIANCE MUST BE REPLACED, IT MUST BE
REPLACED WITH THE SAME TYPE SHOWN OR ITS EQUIVALENT. S'IL FAUT REMPLACER UN FIL
QUELCONQUE D'ORIGINE FOURNI AVEC L'APPAREIL, UTILISER OBLIGATOIREMENT UN FIL M
ÊME
TYPE DONN
É OU SON ÉQUIVALENT.
3.
WHERE REQUIRED BY LOCAL CODES, CONNECT MANUAL RESET LWCO AND HIGH LIMIT AS SHOWN.
4.
DO NOT EXCEED 5.6A TOTAL PUMP CURRENT DRAW (PRIMARY PUMP + SYSTEM PUMP + DHW PUMP +
COMBUSTION AIR DAMPER). FOR PUMPS WITH AMPRATINGS GREATER THAN 5.6A, USE RELAY OR
STARTER COIL CONNECTED TO PUMP TERMINALS ON BOILER 120V PCB.
5.
COMBUSTION AIR DAMPER AND PROVING SWITCH ARE REQUIRED IF USING ROOM AIR FOR COMBUSTION
WITH MOTORIZED DAMPER(S) OR LOUVER(S).
6.
ENERGY MANAGEMENT SYSTEM WIRING CAN BE DONE WITH RJ45 PLUGS OR USING SCREW TERMINALS A, B
AND C LABELED 'EMS (DELTA ONLY)'.
