INSTALLATION AND SERVICE MANUAL

Intelli-Fin®

Hot Water Heating Boilers

Domestic Hot Water Supply Boilers

1,500,000 — 1,700,000 — 2,000,000 Btu/hr Models

FIG. 1 Front View

FIG. 2 Rear View

Installation and service must be performed by a qualified service installer, service agency or the gas supplier.

WARRANTY

Factory warranty (shipped with unit) does not apply to units improperly installed or improperly operated.

Experience has shown that improper installation or system design, rather than faulty equipment, is the cause of most operating problems.

1.Excessive water hardness causing a lime/scale build-up in the copper tube is not the fault of the equipment and is not covered under the manufacturer’s warranty. (See Water Treatment and Water Chemistry)

2.Excessive pitting and erosion on the inside of the copper tube may be caused by too much water

velocity through	the tubes and is not	covered by
the manufacturer’s	warranty (See Boiler	Flow Rates
and Temperature Rise for flow requirements).

SPECIAL INSTRUCTIONS

TO OWNER

NOTE:

Retain this manual for future reference.

This manual supplies information for the installation, operation and servicing of the appliance. It is strongly recommended that this manual be reviewed completely before proceeding with an installation.

WARNING
