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.
• National Electric Code ANSI/NFPA 70.
• For installations in Canada -"Installation
Code for Gas Burning Equipment"
CGA/B149.

Determining Product Location

Before locating the PERFORMANCE 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 is free of any com-
bustible materials, gasoline and other flamma-
ble liquids.
WARNING
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 and its controls
are protected from dripping or spraying water
during normal operation or service.
The PERFORMANCE 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 is replacing an exist-
ing boiler / hot water heater system, the fol-
lowing items should be checked and corrected
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 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.
