11. Efficiency All units have an EF of above 0.90
New Energy Star program for On Demand is 0.82 minimum
IRS tax rebates start at 0.80
Testing verified at ETL or BR Labs

12. S Line Condensing
S Line is the name given to the flow of combustion gas through the heat exchangers
Two heat exchangers, Primary and Wet Recuperative are used to transfer heat from combustion to the water

13. S Line Condensing

14. What does Condensing mean?
Increased efficiency using the by products of combustion to further heat water or air

15. Combustion
During combustion, 1 cubic Meter of Natural Gas (Methane) makes 2 cubic meters of Water Vapor (Steam)

16. Recuperation of Latent Waste Heat

17. So how does it work?
As the combustion gases pass over the heat exchanger heat is transferred to the water
By adding a separate heat exchanger and having the inlet water enter that first additional heat exchange can be obtained removing heat and water from the combustion gas
This removed water is called condensate and must be disposed of
Basic theory is the colder the water entering the wet recuperative heat exchanger the higher the efficiency but…………..
And obviously the higher the water temperature entering the unit the lower the performance gains are

18. Condensate
Condensate is acidic, the colder the water the more acidic the condensate
Therefore it has to be treated and the wet recuperative has to be able to withstand this
This is why condensing water heaters have only recently become a viable option

19. Useful advantages of condensing
Lower Flue gas temperatures
ODW maximum flue gas temperature is 136 DegF
This allows venting in Schedule 40 PVC in all states and provinces, with zero clearance

20. Venting Description – Sealed combustion or Direct Vent
Both Intake and Exhaust air provided to the unit
Ø3” for 099 & 120
Ø4” for 180 & 199

21. Venting
Maximum vent length is 45ft equivalent, this is a per pipe length not a total
Maximum 3 Elbows in vent pipe
Each Elbow = 5ft of straight pipe, therefore with 3 Elbows in the system the maximum length of straight pipe is 30ft
Less elbows = more straight pipe
Termination already included, designed for Side wall mounting only

22. Vent Connection on unit
Recent experience has told us that it needs to be simple to attach the venting to the unit
Plastic connection to accept either 3” or 4” pipe directly on top of the unit
PVC cement is required to bond the two together

24. Unit Control
Standard control is via a wired controller which can be mounted either adjacent to the water heater or in a bathroom
An optional Priority controller is available for a total of 2 controls on the system

25. Controller Up and Down Buttons set the required hot water
temperature from
the unit
Temperature can
be set from
DegF in 2 DegF
increments or
120, 130, 140, 150
& 160 DegF settings
Factory default is 104
On/Off
Button turns the
Unit On or Off
as required
Priority button
allows the second
thermostat to
override the main

26. Optional Priority Controller
Priority Light is lit.
This allows the
Second thermostat
to override the main
Use if you want a
hotter shower than
allowed for a kid’s
shower
Up and Down
Buttons set the
required hot water
temperature from
the unit different to
that of the main
controller
Temperature can
be set from
DegF in 2 DegF
increments or
120, 130, 140, 150
& 160 DegF settings
Factory default is 104

Button turns the
Unit On or Off
as required

27. Delivered Water Temperature Control
A stable delivered water temperature is of paramount importance
We have 3 temperature sensors on this unit
Entering Cold Water temperature
Water temperature exiting the Heat Exchangers
Delivered Water temperature

28. Delivered Water Temperature Control
2 Control valves are used
Flow Control Valve
Measure the flow rate through the unit and report back to the main controller
Minimum flow rate for operation is 0.7 GPM

29. Delivered Water Temperature Control
Bypass Control Valve
This valve allows water to flow from supply to delivered water without passing through the heat exchanger

30. Why Bypass Control?
Mixing in some cold water allows for a stable delivered water temperature, no peaks and troughs due to burner modulation
Increases flow rate as we can provide a mixed condition water temperature
Provides flow control in times of extremely high flow rates

31. End Result
Hi Pro-Tech
Reduced temperature fluctuations compared to competition and previous iterations of On Demand Water heaters

32. Capacity Modulation
In order to provide performance across the range of flow rates available to the unit
Modulation or turn down must be high, these units feature up to 8:1 turn down ratio

33. Modulation Range ODW 099A : 18,000 to 99,000 Btu/h

34. Burner Assembly
Dual burner assembly using in shot type of burner

35. LP Gas Conversion
Replace burner manifold assembly with one specific to LP
Change dip switch #1 to tell the unit that it is now LP

36. Noise Levels Unit uses an up flow design path for the combustion air
This reduces the observed noise level as the induction noise is reduced compared to the previous Quietside units

37. Freeze Protection 48W Ceramic heaters attached to the water pipes
Thermostat controlled when inlet air temperature drops to 41 DegF

38. Safeties 15 Specific Error codes controlling the unit
Overheat, Ignition failure, sensor errors, condensate overflow, air pressure, fan motor, flame failure, freeze protection etc
Error codes displayed on the unit controller
All error codes require unit to be reset, except for freeze protection

39. Bar code tracking system
The unit and the main components such as main circuit board, pump motor, three way valve, modulating gas valve, and plate heat exchanger has an individual bar code
The assemblers scan the data and save it with the bar code of the entire unit to the main server of the facility. If any problems with the components are found, you can trace where the product is installed.

40. Warranty Standard Warranty Residential usage 12 Years Heat Exchanger
5 Years Parts
No labor allowance as standard
