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.

9.3Maximum Category IV Vent Length (Equivalent Length)

A vertical or horizontal remote Category IV vent system must be used with this appliance. The maximum length of field supplied Category IV vent is shown in the chart below titled Category IV Vent Equivalent Length.

Pipe fittings reduce the maximum allowable vent length. Use the Category IV vent manufacturer’s equivalent length deduction for all elbows, terminations, etc. If the information is not readily available from the vent manufacturer, use the Vent Fitting Equivalent Length chart below to find the total equivalent length for all vent fittings in your combustion air system. Then subtract this number of feet from the total equivalent length allowed in Maximum Category IV Vent Equivalent Length chart above. The sum of this calculation is the maximum length of straight vent allowed. If a longer length is required, repeat the calculation using a larger vent size. When using this chart, no additional deduction is required for the addition of the vent system terminal.

9.4CPVC Vent System Design, Construction and Assembly:

The Power VT Plus water heater can be vented either vertically, through a ceiling or roof, or horizontally through a wall. The solid CPVC, (CPVC not allowed on models with “SANI” in the model number) or stainless steel venting listed by a nationally recognized testing laboratory for Category IV positive pressure gas appliance venting can be routed to the outdoors in any direction, from the flue outlet of the water heater economizer, except down. The vent must be installed and supported every four feet 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.

1.Read and follow the information, instructions and warnings in “VENTING” section.

2.Do not insulate the plastic vent pipe.

3.Clean and deburr all solid CPVC (plastic pipe not allowed for venting models with “SANI” in the model number) pipe ends and the joint area and trial assemble the vent before joining with CPVC cement, following the CPVC cement manufacturer’s instructions for making sound air and water tight joints.
