Direct Intake Vent System; Inlet - Takagi Mobius Water Heater T-M32 ASME Installation Manual And Owner's Manual

This T-M32 water heater may be converted to a direct vent (sealed combustion) appliance by
installing an adapter (Part No. TM-DV32) which will bring all required combustible air from
outside the building. When installing the TM-DV32 conversion kit, please follow all instructions
included with the kit.
•
The T-M32 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 T-M32 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.
•
Takagi recommends running the exhaust vent and the intake pipe parallel.
•
The TM-DV32 Direct Vent Kit has an "INLET" mark as shown below. Do not
reverse the INLET and the EXHAUST connections when installing vent pipes.
