SECTION I: FURNACE DESCRIPTION
This furnace is a modulating furnace. It is designed to maximize the
comfort in the home and to minimize the sound level in the home by
varying (modulating) the gas input and the circulating airflow to closely
match the amount of heating needed at any given time.
SECTION II: SAFETY
This is a safety alert symbol. When you see this symbol on
labels or in manuals, be alert to the potential for personal
injury.
Understand and pay particular attention to the signal words DANGER,
WARNING, or CAUTION.
DANGER indicates an imminently hazardous situation, which, if not
avoided, will result in death or serious injury.
WARNING indicates a potentially hazardous situation, which, if not
avoided, could result in death or serious injury.
