Installation guide

INSTALLATIONSECTION 3
Thermal Efficiency up to 98.0% - Fully condensing
design.
Three Pass Flue System - The three pass flue system
keeps the hot combustion gases moving at a high velocity.
The combination of high turbulence and velocity causes an
enormous rate of heat transfer into the water.
Low NOx Premix Power Burner - Developed for the
EC
O
flo Range, a turbulent flame shoots down the
submerged combustion chamber. This turbulence causes
a thorough mixing of the gas and air for optimum
combustion and high heat transfer efficiencies.
Submerged Combustion Chamber - Submerging the
combustion chamber in the centre of the water storage
tank minimizes radiant heat loss and improves efficiency.
Non-CFC foam insulation - Surrounds the tank surface,
saving energy by reducing heat loss.
Electronic Controls - Adjustable electronic thermostat
27º-82ºC recycling Energy Cut Off (E.C.O) shuts off all gas
in event of an overheat condition.
Zero Inch Clearance - The EC
O
flo external jacket is cool
to the touch and is approved for zero inches to
combustibles for unsurpassed installation flexibility.
Vitraglas
®
lined tank - Andrews Water Heater tanks are
protected from the corrosive effects of hot water by an
exclusive ceramic porcelain-like coating. Our high silica
Vitraglas
®
lining provides a tough interior surface.
Electrically powered anodes - Each EC
O
flo product is
supplied with a factory fitted Andrews Correx UP anode
system. This significantly reduces service time due to the
anodes being maintenance free.
Factory installed Hydrojet® Sediment Reduction
System - Cold inlet sediment reduction device made of
stainless steel for increased durability. Helps prevent
sediment build up in tank.
Factory installed dielectric fittings - All heaters
equipped with special water heater nipples for longer
heater life. No special dielectric fittings to buy.
Flexible Venting - The EC
O
flo range can be flued
vertically or horizontally with the Andrews 100/150mm
concentric flue pipe system.
The maximum flue run length is sixteen metres from the
appliance connector to the terminal.
The overall length is reduced if an elbow or condense trap
is fitted (see below).
Determining required flue length -
1. Determine the total length of straight concentric flue
pipe (in metres) required for the installation.
2. Add 1.2 metres of flue for every 90º elbow.
3. Add 0.7 metres of flue for every 45º elbow.
4. Add 1.5 metres for condense trap.
5. Total flue length cannot exceed “Maximum Length” in
the above paragraph.
NOTICE: Do not include the flue terminals in
determining maximum flue installation length.
Three year limited warranty on storage tank - Heavy
gauge steel automatically formed, rolled and welded to
assure a continuous seam for glass lining.
One year limited warranty on parts
