Safety Considerations

Installing and servicing of heating equipment can be hazardous due to gas and electrical components. Only trained personnel should install or service heating equipment.

Untrained personnel can perform basic maintenance such as cleaning and replacing filters. All other operations should be per- formed by trained service personnel. When working on heating equipment, observe precautions in the literature, on tags, and on

labels attached to the unit. Follow all safety codes. Wear safety glasses and work gloves. Have a fire extinguisher available.

Recognize safety information.

To protect against exposed hot surfaces, the downflow vent guard should always be used when the vent pipe is installed along the outside of the furnace casing in a downflow application.

This kit is designed for single- or double-wall 4" pipe. Type B vent connector after the Vent Guard is REQUIRED for all

2-stage furnace applications.
