Determining Product Location
Before locating the PERFORMANCE PLUS
check for convenient locations to:
- Domestic water supply piping
- Heating system piping
- Venting
- Gas supply piping
- Electrical service
Ensure the area chosen for the installation of
the PERFORMANCE PLUS 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 PERFORMANCE PLUS and its
controls are protected from dripping or spray-
ing water during normal operation or service.
The PERFORMANCE PLUS 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 PERFORMANCE PLUS is replacing an
existing boiler / hot water heater system, the
following items should be checked and correct-
ed prior to installation:
• 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 PERFORMANCE PLUS is approved for
zero clearance to combustibles, excluding the
vent hood and vent piping.
Vent hood and vent piping - 2 inches from
combustible materials unless otherwise stated
by the vent pipe manufacturer.
Primary and domestic hot water piping - 1 inch
from combustible material.
