Bacteria can develop in the domestic
water system if certain minimum water
temperatures are not maintained.
Water temperature over 125ºF can cause
severe burns instantly or death from
scalds.
•Children, disabled and elderly are at
highest risk of being scalded.
-Never leave them unattended in or
near shower, bathtub or sink.
-Never allow small children to use a
hot water faucet or draw their own
bath.
• If any one using hot water in the building
fits this description or codes require spe-
cific water temperatures at hot water
faucet, we recommend:
a) ensure the factory installed thermosta-
tic mixing valve is working properly.
b)to set the thermostatic mixing valve
for the lowest temperature which sat-
isfies your hot water need.
.
Protection must be taken against excessive
temperature and pressure!
TO PROTECT AGAINST EXCESSIVE
TEMPERATURE AND PRESSURE
•Check if the Temperature and
Pressure (T&P) relief valve is in the
location provided. (Domestic Water)
•Check if the 30 psi relief valve sup-
plied is in the location provided.
(Primary water)
•To avoid injury, install the relief
devices to comply with local code
requirements.

Code, provided that:
-Outer tank water (including additives)
is practically non-toxic, having toxicity
rating or Class of 1, as listed in Clinical
Toxicology of Commercial Products,
-Outer tank pressure is limited to maxi-
mum 30 psig by approved relief valve.
Single wall heat exchangers are permitted under
the Uniform Plumbing code - Paragraph L3.2. if
they satisfy all of the following requirements.
1. The heat transfer medium is potable
water or contains only substances which
are recognized as safe by the U.S. Food
and Drug Administration.
2. The pressure of the heat transfer medium
is maintained less than the normal mini-
mum operating pressure of the potable
water system
3. The equipment is permanently labeled
to indicate that only additives recog-
nized as safe by the FDA shall be used in
the heat transfer medium.

SECTION I - Pre-Installation Items
Code Compliance
This product must be installed in accor-
dance to the following:
• All applicable local, state, national and
provincial codes, ordinances, regula-
tions and laws.
• The National Fuel Gas Code NFPA54/
ANSI Z332.1 - Latest edition.
•Installation of Oil Burning Equipment
NFPA 31 - Latest Edition
• National Electric Code ANSI/NFPA 70.
• For installations in Canada -“Installation
Code for Gas Burning Equipment”
CGA/B149.
•For installations in Canada - Installation
code for Oil Burning Equipment -
CSA/B139.
Determining Product Location
Before locating the ELITE check for conve-
nient locations to:
-Domestic water supply piping
-Heating system piping
-Venting
-Gas or oil supply piping
-Electrical service
Ensure the area chosen for the installation of
the ELITE is free of any combustible materials,
gasoline and other flammable liquids.
Failure to remove or maintain the area
free of combustible materials, gasoline
and other flammable liquids or vapors
can result in severe personal injury,
death or substantial property damage.
Ensure the ELITE and its controls are protect-
ed from dripping or spraying water during nor-
mal operation or service.
The ELITE should be installed in a location so
that any water leaking from the tank or piping
connections or relief valves will not cause
damage to the area surrounding the unit or any
lower floors in the structure.
-When such a location is unavoidable a
suitable drain pan with adequate
drainage should be placed under the
unit. The drain pan must not restrict the
flow of combustion air to the unit.
Boiler Replacement
If the ELITE is replacing an existing boiler /
hot water heater system, the following items
should be checked and corrected prior to instal-
lation:
•Primary and domestic piping leaks and
corrosion.
• Improper location and sizing of the
expansion tank on the primary heating
loop.
• Improper sizing of the thermal expan-
sion tank (if used) on the domestic sup-
ply line.
•Vent condition and sizing.
Recommended Clearances
The ELITE is approved for zero clearance to
combustibles, excluding the vent hood and
vent piping.
Vent hood and vent piping - 6 inches from
combustible materials when using type “L”
double wall vent.
Vent Piping - 18 inches from combustible
materials when using single wall vent.
Primary and domestic hot water piping - 1 inch
from combustible material.
