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.
