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.
