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

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

S Line Condensing

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

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

Recuperation of Latent Waste Heat

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

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

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

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

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

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

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

Controller Up and Down Buttons set the required hot water temperature from the unit Temperature can be set from 98-114 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

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 98-114 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

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

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

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

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

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

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

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

Burner Assembly Dual burner assembly using in shot type of burner

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

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

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

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

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.
