IMPORTANT INSTRUCTIONS FOR SSVH MODELS
HOW THESYSTEM WORKS WITHRADIANTHEAT
BOTH THE SUPER-E SSV AND SSVH MODELS ARE VERY EFFICIENT AND POWERFUL WATER HEATING DEVICES. THE
SUPER-E SSV AND SSVH MODELS PRODUCE LARGER AMOUNTS OF HOT WATER IN A VERY SMALL COMPACT DESIGN,
WHEN COMPARED WITH CONVENTIONAL WATER HEATERS. HEAT TRANSFER PRODUCTS HAS DESIGNED THE SUPER-E
SSVH MODEL EXCLUSIVELY AS A COMBINED HOT WATER/RADIANT SPACE WATER HEATER. THE UNITS ARE BUILT WITH
A SECONDARY HEAT EXCHANGER TO TRANSFER HEAT FROM THE STORED WATER INTO THE CIRCULATOR LOOP FOR
THE FLOOR, CEILING, OR BASEBOARD RADIANT SYSTEM. THIS SECONDARY HEAT EXCHANGER ALLOWS THE SUPER-E
SSVH MODEL TO HEAT BOTH THE DOMESTIC WATER AND PROVIDE OUTPUT BY THE INSTALLATION OF A RE-CIRCULA-
TION LINE CONNECTED FROM DOMESTIC HOT WATER OUTLET TO DOMESTIC COLD WATER INLET. THE SUPER-E
SSVH-130 MODEL CAN TRANSFER UP TO 110,000 BTU’s IN THE SECONDARY HEAT EXCHANGER AND ALSO DELIVER 180
GALLONS OF HOT WATER IN THE FIRST HOUR OF OPERATION. EVEN SUPER-E SSV MODELS MAKE GREAT RADIANT
HEATERS, WHEN DOMESTIC HOT WATER IS NOT NEEDED IN THE INSTALLATION. ANOTHER IMPORTANT FEATURE IS
THAT BOTH SSV AND SSVH MODELS HAVE THE ABILITY TO DIRECT VENT WITH A ZERO CLEARANCE TOLERANCE TO ANY
COMBUSTIBLE SURFACE, WHICH ENABLES THE SUPER-E TO BE INSTALLED VIRTUALLY ANYWHERE! THIS TYPE OF
POWER, EFFICIENCY, AND INSTALLATION FLEXIBILITY IN SSV AND SSVH MODEL APPLIANCES IS A SUPER-E EXCLUSIVE
THAT NO OTHER WATER HEATER MANUFACTURER CAN OFFER!
HOW THESYSTEM WORKS WITHHEATING/COOLING
BOTH SSV AND SSVH MODELS CAN WORK IN CONNECTION WITH AIR HANDLING EQUIPMENT TO PROVIDE AIR OR RADI-
ANT HEATING, COOLING, AND DOMESTIC HOT WATER. THESE TYPES OF SYSTEMS PROVIDE THE ADVANTAGE OF
ZONED HEATING AND COOLING; WHICH PROVIDE MUCH GREATER COMFORT AND OPERATING EFFICIENCY VERSUS
CONVENTIONAL SYSTEMS.
HOW TO INSTALLTHESYSTEM
IN THIS MANUAL YOU WILL FIND SAMPLE DRAWINGS WHICH CAN PROVIDE YOU WITH IDEAS ON HOW TO LAY OUT THE
SYSTEM. THE USE OF A MIXING VALVE IS ALWAYS RECOMMENDED TO ACHIEVE FLEXIBILITY IN ADJUSTING TEMPERA-
TURE TO MEET THE SYSTEM DEMAND. IT IS ESSENTIAL TO READ THIS INSTALLATION MANUAL TO ASSURE PROPER
OPERATION OF THE VOYAGER SYSTEM. AREAS IN THIS MANUAL THAT NEED SPECIAL ATTENTION ARE “CONDENSATE
REMOVAL”; “VENTING OF COMBUSTION GASES”; AND “CONNECTION OF A BRONZE CIRCULATOR BETWEEN DOMESTIC
HOT WATER OUTLET, DOMESTIC COLD WATER INLET”.
NOTE:
IT IS VERY IMPORTANT TO FOLLOW EITHER LOCAL OR FEDERAL PLUMBING CODES WHEN INSTALLING AND OPERATING
A MIXING VALVE FOR A DOMESTIC HOT WATER SYSTEM!
HOW TO SIZE THECOMBINATIONSYSTEM FOR RADIANTHEATING
IT IS IMPORTANT TO SIZE BOTH HEATING LOAD AND DOMESTIC HOT WATER LOAD, IN CHOOSING WHICH SUPER-E SSVH
MODEL YOU WILL NEED TO PURCHASE FOR THE JOB. ON THE FOLLOWING PAGE IS A CHART WHICH REPRESENTS
DESIGN OUTPUTS OF THE SECONDARY HEAT EXCHANGER IN THE SUPER-E SSVH MODEL. THIS CHART OUTLINES OUT-
PUT CHARACTERISTICS IN TERMS OF FLOW RATE THROUGH THE SECONDARY HEAT EXCHANGER, TEMPERATURE RISE,
AND BTU OUTPUT. IT IS IMPORTANT TO CHECK WITH YOUR RADIANT SUPPLIER ON THE OUTPUT TEMPERATURE,
DESIGN TEMPERATURE RISE OR DELTA TEE, AND THE TOTAL BTU OUTPUT REQUIRED FOR THE JOB. A BRONZE CIRCU-
LATOR BETWEEN DOMESTIC HOT WATER OUTLET AND DOMESTIC COLD WATER INLET IS REQUIRED. ONCE YOU HAVE
DETERMINED YOUR SYSTEM OUTPUT REQUIREMENTS, REFER TO “SUPER-E SSVH MODEL SIZING CHART” ON NEXT
PAGE TO DETERMINE MODEL AND FLOW RATE REQUIRED THROUGH THE SECONDARY HEAT EXCHANGER; IN ORDER TO
MEET THE LOADS OF THE SYSTEM. EXAMPLES ARE PROVIDED TO GUIDE THROUGH THE SELECTION PROCESS. ONCE
WE KNOW THAT THE SECONDARY HEAT EXCHANGER HAS BEEN SIZED CORRECTLY TO MEET THE RADIANT HEAT LOAD,
WE MUST NOW LOOK INTO THE HOT WATER LOAD. FIRST YOU NEED TO UNDERSTAND THE DIFFERENCE BETWEEN
FIRST DRAW CAPACITY AND FIRST HOUR CAPACITY. FIRST DRAW CAPACITY IS ESTABLISHED AS THE TIME FRAME AT
DIFFERENT OUTPUT RATES WHICH THE SUPER-E SSVH MODEL CAN DELIVER THE DESIRED TEMPERATURE BEFORE THE
TANK RATE INPUT AND STORAGE ARE CONSUMED. THIS USUALLY OCCURS WHEN THERE IS A LARGER DRAW OF HOT
WATER IN A VERY SHORT TIME FRAME. (
EXAMPLE: HOT TUB 80 GALLON WITH A FILL RATE OF 10 MINUTES) FIRST
HOUR RATING IS ESTABLISHED AS A RATING SYSTEM TO COMPARE THE WATER HEATER’S ABILITY TO RECOVER OVER A
ONE HOUR PERIOD. THE FIRST HOUR RATING CAN BE VERY MISLEADING WHEN THE HOT WATER LOAD IS REQUIRED IN
A VERY SHORT PERIOD OF TIME. NOW WE CAN DETERMINE WHICH SUPER-E SSVH MODEL WILL SUIT YOUR NEEDS FOR
THE JOB. TO DO THIS, REFER TO THE DOMESTIC HOT WATER CHART. IF THE DOMESTIC HOT WATER DEMANDS EXCEED
THE SUPER-E SSVH’S CAPACITY, THEN A STORAGE RE-CIRCULATION TANK CAN BE INSTALLED TO MEET THE SYSTEM
HOT WATER LOAD. AFTER YOU HAVE SIZED YOUR DOMESTIC LOAD AND HEATING LOAD, YOU ARE NOW READY TO
CHOOSE THE SUPER-E SSVH MODEL SUITABLE FOR THE JOB!
