					labels or in manuals, be alert to the potential for personal injury.
conditioners designed for outdoor installation. Only gas piping,

electric power and duct connections are required at the point of installation.

The single or two stage gas-fired heaters have spark to pilot ignition. The tubular heat exchangers are aluminized steel.

The refrigerant system is fully charged with R-410A Refrigerant, and is tested and factory sealed.

Understand and pay particular attention 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.

CAUTION indicates a potentially hazardous situation, which, if

not avoided may result in minor or moderate injury. It is also

used to alert against unsafe practices and hazards involving only property damage.
