5. VENTING
PLATINUM
models with “SANI” in the model number are designed for operation with a "positive pressure vent
system" constructed of locally obtained 4" schedule 40 or 80 solid
CPVC
pipe. Do
not
use PVC pipe of any type.
Do
not
use CPVC pipe with cell/foam type construction (such as “CellCore”) or other non-solid CPVC plastic
pipe. Larger solid CPVC pipe may be substituted; however, a solid CPVC increaser from 4” to the larger size
must be used for connection to the stainless steel 4” male flue outlet from the water heater. Do not insulate the
plastic vent pipe. Stainless steel venting listed by a nationally recognized testing laboratory for category IV
positive pressure gas appliance venting may be used instead of plastic pipe venting.
WARNING: On PLATINUM
models with “SANI” in the model number, use only solid CPVC pipe venting
or stainless steel venting listed by a nationally recognized testing laboratory for category IV positive
pressure gas appliance venting. Use of PVC, ABS, pipe with cell/foam type construction, plastic vent
pipe other than solid CPVC or use of venting materials other than specified in these instructions can
result in failure of the venting system and/or exposure to carbon monoxide which can result in property
damage, personal injury or death.
The PLATINUM
(except models with “SANI” in the model number, see above) is designed for operation with a
"positive pressure vent system" constructed of locally obtained 4" schedule 40 or 80 solid PVC or CPVC pipe.
Do
not
use PVC or CPVC pipe with cell/foam type construction (such as “CellCore”) or other non-solid PVC or
CPVC plastic pipe. Larger solid PVC or CPVC pipe may be substituted; however a solid PVC or CPVC increaser
from 4” to the larger size must be used for connection to the stainless steel 4” male flue outlet from the water
heater. Do not insulate the plastic vent pipe. Stainless steel venting listed by a nationally recognized testing
laboratory for category IV positive pressure gas appliance venting may be used instead of plastic pipe venting.
WARNING: On PLATINUM,
(except models with “SANI” in the model number, see above) use only solid
PVC pipe, solid CPVC pipe or stainless steel venting listed by a nationally recognized testing laboratory
for category IV positive pressure gas appliance venting. Use of ABS, pipe with cell/foam type
construction, plastic vent pipe other than solid PVC or CPVC or use of venting materials other than
specified in these instructions can result in failure of the venting system and/or exposure to carbon
monoxide which can result in property damage, personal injury or death.
WARNING: Do not vent this water heater into an existing or traditional gas vent or chimney or combine
the vent with any other appliance. Such venting could result in failure of the venting system and/or
exposure to carbon monoxide which can result in property damage, personal injury or death.
CAUTION
: DO NOT use ABS pipe in venting system. ABS can emit toxic fumes in the event of a building fire.
5.1
Vent System Design
The PLATINUM
water heater can be vented either vertically, through a ceiling or roof, or horizontally through a
wall. From the flue outlet of the water heater the solid PVC, (PVC not allowed on models with “SANI” in the
model number) solid CPVC venting or stainless steel venting listed by a nationally recognized testing laboratory
for category IV positive pressure gas appliance venting can be routed in any direction except down. The vent
must be installed and supported to slope downward toward the water heater vent connection with at least ¼ inch
drop per linear foot of horizontal vent run, to allow proper drainage of accumulated condensation.
Follow all requirements in the General “Venting” section of this manual and other instructions and markings for
venting flue products to the outdoors, obtaining adequate combustion and ventilation air and general installation
instructions.
5.2
Venting of Multiple Units
Multiple PLATINUM
models
must not
be vented into a common duct or breeching. Each unit must be
independently vented in accordance with the instructions for either horizontal or vertical venting included above.
