DIRECT INTAKE VENT SYSTEM
This Hydro-Smart 170 may be converted to a direct vent (sealed combustion) appliance by
installing an adapter (Part No. TK-TV10) which will bring all required combustible air from
outside the building. When installing the TK-TV10 conversion kit, please follow all instructions
included with the kit.
•
The Hydro-Smart 170 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 Hydro-Smart 170 requires a 3” 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.
