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.
