SAFETY CONSIDERATIONS
Recognize safety information. This is the safety-alert symbol /_.
When you see this symbol on the furnace and in instructions or
manuals, be alert to the potential for personal iniury.
Understand the signal words: DANGER, WARNING, and
CAUTION. DANGER identifies the most serious hazards which
will result in severe personal iniury or death. WARNING signifies
hazards which could result in personal iniury or death. CAUTION
is used to identify unsafe practices which may result in minor
personal iniury or product and property damage. NOTE is used to
highlight suggestions which will result in enhanced installation,
reliability or operation.
To minimize the possibility of serious personal iniury, fire, furnace
damage, or improper operation; carefully follow these safety
rules:
• Your gas furnace uses air from outside the home for combustion
and vents flue gas to the outdoors. It is not to be installed using
indoor air for combustion. The vent pipe must terminate outside
the structure and must not be obstructed in any way. The
air-intake pipe must terminate outside the structure or in a well
ventilated area that is isolated from the living space and the
garage (e.g. well ventilated attic or crawlspace). Do not block or
obstruct air openings on furnace or spaces around furnace.
• Keep the area around your furnace clear and free of combustible
materials, gasoline, and other flammable liquids and vapors.

Summary

Safety Considerations Overview

Understanding Signal Words

Explanation of signal words (DANGER, WARNING, CAUTION) used in manuals to denote hazard levels and potential injury.

Combustion Air and Venting Rules

Furnace uses outside air for combustion and vents outdoors. Vent pipe must be clear; air-intake pipe must terminate outside or in a well-ventilated area.

Combustion Air Requirements

Signals of Insufficient Combustion Air

Symptoms like headaches, dizziness, excessive humidity, or fireplace smoke not drawing up indicate insufficient air for combustion.

Action for CO Symptoms

If experiencing symptoms like headaches or dizziness, leave the house immediately and call your gas supplier.

Performing Combustion Air Check

Procedure for checking combustion air by testing vent pipe draft with a match flame under specific conditions.

Correcting Draft Hood Spillage

Steps to correct draft hood spillage, including checking vents, opening windows, and installing permanent air ducts.

Indoor Humidity Management

Testing Indoor Humidity Levels

Methods to test indoor humidity, including observing window condensation and an ice cube test for dryness.

Lowering Indoor Humidity

Tips to reduce indoor humidity, such as using exhaust fans, cooking with covered pans, and installing fresh air intake ducts.

About Your Furnace Components

Circulating Air Blower Operation

The blower circulates room air through the furnace and ducts. It operates automatically or manually via the thermostat.

Thermostat Functionality

Thermostats control heating and cooling, with fan switches (AUTO/ON) and programmable set-backs for temperature control.

Furnace Rating Plate Information

The rating plate contains essential model, manufacturing, and serial numbers for service and parts requests.

Door Interlock Switch Function

This switch interrupts electrical power when the blower door is removed, preventing furnace operation for safety.

Furnace Control System

The furnace control manages the circulating air blower's operation and includes a fan off-delay adjustment.

Furnace Operation and Safety

Ignition and Lockout Procedures

Details furnace ignition sequence, burner operation, and lockout procedures if ignition fails after multiple cycles.

Pressure Switch Function

Starting the Furnace Sequence

Step-by-step guide to starting the furnace, including thermostat settings, gas valve operation, and electrical power.

Extended Shutdown and Propane Models

Extended Shutdown Procedure

Steps for safely shutting down the furnace for extended periods, including turning off gas and electrical power.

Propane Gas Model Hazards

Warning for propane gas models: gas is heavier than air, can settle in low areas, and may require a warning device.

Frozen Pipe Hazard Prevention

Preventing Frozen Water Pipes

During freezing weather, take precautions like draining pipes or ensuring the home remains warm to prevent damage.

Winter Shutdown for 90+ Furnaces

Protecting Condensate System

Procedure to protect the plastic transition box and condensate trap from freeze damage using RV antifreeze.

Furnace Maintenance and Labeling

Annual Furnace Inspection

It is recommended to have the furnace inspected and serviced annually by a qualified service agency before the heating season.

Electrical Work Safety

Warning to label wires before disconnection and only allow qualified agencies to perform electrical service.

Filter Maintenance and Replacement

Air Filter Inspection and Cleaning

Filters should be inspected monthly and cleaned or replaced. Dirty filters cause inadequate heating or cooling performance.

Selecting Replacement Filters

Replacement filters must match original type, size, and rating. Disposable filters may replace washable types if airflow is doubled.

Filter Replacement Procedures
