DIRECT INTAKE VENT SYSTEM
This water heater may be converted to a direct-vent (sealed combustion) appliance by installing
an adapter (Part No. 9007668005 (TM-DV32)) which will bring all required combustible air from
outside the building. When installing the direct-vent conversion kit, please follow all instructions
included with the kit.
 The water heater must be installed in a location where the proper amount of combustible
air will be available to it at all times without obstructions.
 If used as a direct-vent appliance, the water heater requires a 4” combustible air supply
pipe. The intake pipe must be sealed airtight.
 Air supply pipe can be made of ABS, PVC, galvanized steel, corrugated aluminum,
corrugated stainless steel or Category III stainless steel.
 Change the dipswitch settings to the direct-vent system. (See diagram below)
 Sidewall venting is recommended for the direct-vent system.
 The manufacturer recommends running the exhaust vent and the intake pipe parallel.
 The Direct-Vent Conversion Kit has an “INLET” mark as shown below. Do not
reverse the INLET and the EXHAUST connections when installing vent pipes.
