HE RUBBER ELBOW IS NOT DESIGNED TO SUPPORAT A LOAD.
RUBBER ELBOW IS MOUNTED EXTERNALLY TO THE FURNACE CABINET,
EXTREME CARE MUST BE TAKEN TO ADEQUATELY SUPPORT FIELD-SUPPLIED
VENT/FLUE PIPING, AS DAMAGE CAN RESULT IN LEAKS CAUSING BODILY
INJURY OR DEATH DUE TO EXPOSURE TO FLUE GASES, INCLUDING CARBON
MONOXIDE.
For upright installations, externally mount the rubber el-
bow to the vent/flue coupling using a worm gear hose clamp.
Secure field supplied vent/flue piping to the rubber elbow
using a worm gear hose clamp. NOTE: Use of the alternate
vent/flue location for upright installations, requires the drain
trap be installed on the same side of the unit as the flue
pipe.
For horizontal installations, externally secure the field-sup-
plied vent/flue pipe directly to the vent/flue coupling using a
PVC or ABS coupling or elbow.
