50M56-743

Integrated Single or Two-Stage

HSI Integrated Furnace Control Kit

INSTALLATION INSTRUCTIONS

DESCRIPTION

The 50M56-743 kit is an automatic gas HSI Integrated Furnace

Control that employs a microprocessor to continually monitor,

analyze, and control the proper operation of the gas burner,

inducer, and fan.

Signals interpreted during continual surveillance of the

thermostat and ﬂame sensing element initiate automatic

ignition of the burner, sensing of the ﬂame, and system shut-

off during normal operation.

These controls incorporate system fault analysis for quick gas

ﬂow shut-off, coupled with automatic ignition retry upon sensing

a fault correction.

Installation should be done by a qualiﬁed heating and air

conditioning contractor or licensed electrician.

If in doubt about whether your wiring is millivolt, line, or low

voltage, have it inspected by a qualiﬁed heating and air

conditioning contractor or licensed electrician.

Do not exceed the speciﬁcation ratings.

All wiring must conform to local and national electrical codes

and ordinances.

This control is a precision instrument, and should be handled

carefully. Rough handling or distorting components could

cause the control to malfunction.

Following installation or replacement, follow manufacturer’s

recommended installation/service instructions to ensure

proper operation.

PRECAUTIONS

CAUTION

Do not short out terminals on gas valve or primary

control. Short or incorrect wiring may damage the

thermostat.

Failure to comply with the following warnings could result

in personal injury or property damage.
