SAFETY CONSIDERATIONS
Installing and servicing water heating equipment can be hazardous due to gas and electrical components. Installation and service of the concentric vent termination requires ability equivalent to that of a qualified installer or service agent, see page 7. All precautions in the literature, on tags, and labels attached to the unit must be observed.
Follow all safety codes. Wear safety glasses and work gloves.

INSTALLATION PROCEDURE 1 ROOF TERMINATION, see Figure 23.
1. Determine best location for termination kit.
NOTE: Roof termination is preferred since it is less susceptible to damage, has reduced chances to intake contaminants, and less visible vent vapors.
2.Cut 1 hole (5 in. diameter)
3.Partially assemble concentric vent termination kit.
a)Cement Y concentric fitting to larger diameter kit pipe, see Figure 20.
b)Cement rain cap to smaller diameter kit pipe, see Figure 22.
Figure 22.
NOTE: Instead of cementing the smaller pipe to the rain cap, a
When using alternate screw method, drill clearance hole in rain cap and pilot hole in vent pipe for screw size being used. Failure to drill adequate holes may cause cracking of PVC components, allowing combustion products to be recirculated. Failure to follow this warning could result in personal injury or death.
Do not operate the heater with rain cap removed or recirculation of combustion products may occur. Water may also collect inside larger
4.Install Y concentric fitting and pipe assembly through structure’s hole and field supplied roof boot/flashing.
Figure 23.
NOTE: Do not allow insulation or other materials to accumulate inside pipe assembly when installing through hole.
