GENERAL NOTES

1. EXISTING INFORMATION SHOWN ON DRAWINGS HAS BEEN TAKEN FROM LIMITED FIELD OBSERVATIONS. FIELD VERIFY EXISTING CONDITIONS PRIOR TO BEGINNING WORK.

2. EXISTING GAS PIPE, WATER PIPE, VENT PIPE, AND ELECTRICAL THAT CONFORMS TO THESE DRAWINGS, THE REFERENCED CODES, AND MANUFACTURER'S REQUIREMENTS MAY BE RE-UTILIZED.

3. PHOTOS SHOW EXISTING CONDITIONS SURROUNDING THE AREAS FOR NEW WORK. FILED VERIFY CONDITIONS PRIOR TO BEGINNING WORK.

4. DRAWING IS SCHEMATIC IN NATURE AND IS INTENDED ONLY TO SHOW REQUIRED PRODUCTS AND REQUIREMENTS. THE CONTRACTOR SHALL BE RESPONSIBLE FOR LAYING OUT THE PROJECT IN A NEAT

WORKMANLIKE MANNER THAT DOES NOT OBSTRUCT ANY REQUIRED BUILDING OR EQUIPMENT SUCH AS ELECTRICAL PANELBOARDS AND ALLOWS FOR FULL ACCESS TO PERFORM ROUTINE AND

PREVENTATIVE MAINTENANCE ON INSTALLED EQUIPMENT INCLUDING INTAKE FILTERS, VALVES, CONTROL BOARDS, ETC.

5. THE FOLLOWING TERMS IN ANY COMBINATION RELATING TO THE INSTALLATION OF PRODUCTS/MATERIALS: INSTALL, FURNISH, PROVIDE, OR SIMILAR STATEMENTS; MEAN THAT THE CONTRACTOR IS

RESPONSIBLE FOR THE PROCUREMENT AND INSTALLATION OF THE PRODUCTS UNLESS IT IS SPECIFICALLY DESIGNATED AS A GOVERNMENT FURNISHED ITEM, SUPPLY ONLY PRODUCT, OR SPARE.

KEY NOTES

EACH WATER HEATER SHALL BE ON DEDICATED 120V 15A BRANCH CIRCUIT WITH DISCONNECT SWITCH AT EACH WATER HEATER. FINAL CONNECTION TO WATER HEATERS FROM SWITCH SHALL

BE IN LIQUID TIGHT AC OR MC RACEWAY. ALL OTHER CONDUIT SHALL BE IN EMT RACEWAY. VERIFY EXISTING CONDITIONS AND MODIFY, EXTEND, OR PROVIDE NEW AS REQUIRED FOR

INSTALLATION.

EXHAUST VENT: 2" MINIMUM (3" FOR DEVELOPED VENT LENGTHS EXCEEDING 25') PER MANUFACTURER'S RECOMMENDATIONS. INSTALL CONDENSATE DRAIN WITH NEUTRALIZING KIT FOR EACH

WATER HEATER AND EXTEND TO SUITABLE FLOOR DRAIN OR CONDENSATE PUMP.

INTAKE VENT: 2" MINIMUM (3" FOR DEVELOPED VENT LENGTHS EXCEEDING 25') PER MANUFACTURER'S RECOMMENDATIONS, PROVIDE TRAP/DRAIN IF INSTALLATION IS RECOMMENDED BY

MANUFACTURER.

MODIFY HOT AND COLD WATER PIPING TO PROVIDE APPROXIMATELY EQUAL PIPE LENGTHS AND MATCHING VALVES AND FITTINGS FOR EACH WATER HEATER. PROVIDE GLOBE

(ISOLATION/THROTTLING) VALVES ON THE COLD WATER SUPPLY LINE FOR EACH TANK. PROVIDE FULL PORT BALL VALVE (ISOLATION ONLY) ON THE OUTLET SIDE OF EACH WATER HEATER.

PROVIDE COMBINATION TEMPERATURE AND PRESSURE GAUGES ON THE OUTLET SIDE OF EACH WATER HEATER PRIOR TO ISOLATION VALVE.
