B. Design and Installation Considerations

Heatilator direct vent gas appliances are designed to op- erate with all combustion air siphoned from outside of the building and all exhaust gases expelled to the outside. No additional outside air source is required.

Installation MUST comply with local, regional, state and national codes and regulations. Consult insurance carrier, local building inspector, fire officials or authorities having jurisdiction over restrictions, installation inspection and permits.

Before installing, determine the following:

•Where the appliance is to be installed.

•The vent system configuration to be used.

•Gas supply piping.

•Electrical wiring requirements.

•Framing and finishing details.

•Whether optional accessories—devices such as a fan, wall switch, or remote control—are desired.

Improper installation, adjustment, alteration, service or maintenance can cause injury or property damage. For assistance or additional information, consult a qualified service technician, service agency or your dealer.
