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
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
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
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
• ODW 120A : 18,000 to 120,000 Btu/h
• ODW 180A : 26,000 to 180,000 Btu/h
• ODW 199A : 26,000 to 199,000 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.
Warranty
Standard Warranty Residential usage
• 12 Years Heat Exchanger
• 5 Years Parts
• No labor allowance as standard
