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
![Page 12: Product Introduction January 2009](https://reader033.fdocuments.in/reader033/viewer/2022051521/5a4d1aee7f8b9ab05997c80f/html5/thumbnails/12.jpg)
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
![Page 13: Product Introduction January 2009](https://reader033.fdocuments.in/reader033/viewer/2022051521/5a4d1aee7f8b9ab05997c80f/html5/thumbnails/13.jpg)
S Line Condensing

• Increased efficiency using the by products of combustion to further heat water or air
What does Condensing mean?
![Page 15: Product Introduction January 2009](https://reader033.fdocuments.in/reader033/viewer/2022051521/5a4d1aee7f8b9ab05997c80f/html5/thumbnails/15.jpg)
Combustion• During combustion, 1 cubic Meter of Natural Gas
(Methane) makes 2 cubic meters of Water Vapor (Steam)

Recuperation of Latent Waste Heat
![Page 17: Product Introduction January 2009](https://reader033.fdocuments.in/reader033/viewer/2022051521/5a4d1aee7f8b9ab05997c80f/html5/thumbnails/17.jpg)
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
![Page 18: Product Introduction January 2009](https://reader033.fdocuments.in/reader033/viewer/2022051521/5a4d1aee7f8b9ab05997c80f/html5/thumbnails/18.jpg)
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
![Page 19: Product Introduction January 2009](https://reader033.fdocuments.in/reader033/viewer/2022051521/5a4d1aee7f8b9ab05997c80f/html5/thumbnails/19.jpg)
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
![Page 20: Product Introduction January 2009](https://reader033.fdocuments.in/reader033/viewer/2022051521/5a4d1aee7f8b9ab05997c80f/html5/thumbnails/20.jpg)
Venting
• Description – Sealed combustion or Direct Vent
• Both Intake and Exhaust air provided to the unit
• Ø3” for 099 & 120• Ø4” for 180 & 199
![Page 21: Product Introduction January 2009](https://reader033.fdocuments.in/reader033/viewer/2022051521/5a4d1aee7f8b9ab05997c80f/html5/thumbnails/21.jpg)
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
![Page 22: Product Introduction January 2009](https://reader033.fdocuments.in/reader033/viewer/2022051521/5a4d1aee7f8b9ab05997c80f/html5/thumbnails/22.jpg)
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
![Page 23: Product Introduction January 2009](https://reader033.fdocuments.in/reader033/viewer/2022051521/5a4d1aee7f8b9ab05997c80f/html5/thumbnails/23.jpg)

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
![Page 25: Product Introduction January 2009](https://reader033.fdocuments.in/reader033/viewer/2022051521/5a4d1aee7f8b9ab05997c80f/html5/thumbnails/25.jpg)

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
![Page 28: Product Introduction January 2009](https://reader033.fdocuments.in/reader033/viewer/2022051521/5a4d1aee7f8b9ab05997c80f/html5/thumbnails/28.jpg)
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
![Page 29: Product Introduction January 2009](https://reader033.fdocuments.in/reader033/viewer/2022051521/5a4d1aee7f8b9ab05997c80f/html5/thumbnails/29.jpg)
Delivered Water Temperature Control
• Bypass Control Valve
• This valve allows water to flow from supply to delivered water without passing through the heat exchanger
![Page 30: Product Introduction January 2009](https://reader033.fdocuments.in/reader033/viewer/2022051521/5a4d1aee7f8b9ab05997c80f/html5/thumbnails/30.jpg)
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
![Page 31: Product Introduction January 2009](https://reader033.fdocuments.in/reader033/viewer/2022051521/5a4d1aee7f8b9ab05997c80f/html5/thumbnails/31.jpg)
End Result
• Hi Pro-Tech
• Reduced temperature fluctuations compared to competition and previous iterations of On Demand Water heaters
![Page 32: Product Introduction January 2009](https://reader033.fdocuments.in/reader033/viewer/2022051521/5a4d1aee7f8b9ab05997c80f/html5/thumbnails/32.jpg)
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
![Page 33: Product Introduction January 2009](https://reader033.fdocuments.in/reader033/viewer/2022051521/5a4d1aee7f8b9ab05997c80f/html5/thumbnails/33.jpg)

![Page 34: Product Introduction January 2009](https://reader033.fdocuments.in/reader033/viewer/2022051521/5a4d1aee7f8b9ab05997c80f/html5/thumbnails/34.jpg)
Burner Assembly
• Dual burner assembly using in shot type of burner
![Page 35: Product Introduction January 2009](https://reader033.fdocuments.in/reader033/viewer/2022051521/5a4d1aee7f8b9ab05997c80f/html5/thumbnails/35.jpg)
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
![Page 36: Product Introduction January 2009](https://reader033.fdocuments.in/reader033/viewer/2022051521/5a4d1aee7f8b9ab05997c80f/html5/thumbnails/36.jpg)
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
![Page 37: Product Introduction January 2009](https://reader033.fdocuments.in/reader033/viewer/2022051521/5a4d1aee7f8b9ab05997c80f/html5/thumbnails/37.jpg)
Freeze Protection
• 48W Ceramic heaters attached to the water pipes
• Thermostat controlled when inlet air temperature drops to 41 DegF
![Page 38: Product Introduction January 2009](https://reader033.fdocuments.in/reader033/viewer/2022051521/5a4d1aee7f8b9ab05997c80f/html5/thumbnails/38.jpg)
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
![Page 39: Product Introduction January 2009](https://reader033.fdocuments.in/reader033/viewer/2022051521/5a4d1aee7f8b9ab05997c80f/html5/thumbnails/39.jpg)
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.
