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.

INTRODUCTION
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.
