Safety Considerations - State Water Heaters A B C D E F 100 Instruction Manual

This concentric vent termination kit may be used with 3 or 4 inch diameter
pipe systems. When connecting to a 4 in. diameter pipe system a 3 x 4
inch field supplied reducer is to be installed at the intake and exhaust
connection of the concentric vent termination kit.

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 2. 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.

* Dimension 21 1/8 in. may be lengthened to 60 in. maximum.
Dimension 21 1/8 in. may also be shortened by cutting the
pipes, provided in the kit, to 12 in. minimum.
** Dimension 39 will change accordingly as dimension
21 1/8 in. is lengthened or shortened.

INSTALLATION PROCEDURE 1 ROOF TERMINATION,
see figure c.
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 A.
b) Cement rain cap to smaller diameter kit pipe, see Figure A.
note: Instead of cementing the smaller pipe to the rain cap, a
field-supplied stainless steel screw may be used to secure the
2 components together when field disassembly is desired for
cleaning, see figure d.
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 combustion-air pipe and flow to the burner enclosure.
failure to follow this warning could result in product damage or
improper operation, personal injury or death.
4. Install Y concentric fitting and pipe assembly through
structure's hole and field supplied roof boot/flashing.
note: do not allow insulation or other materials to accumulate
inside pipe assembly when installing through hole.
