Introduction The Ubbink Rolux® concentric vent system is considered part of the direct vent tankless water heater. The Ubbink Rolux® concentric vent system was tested and approved with the appliance by a third party testing agency. Check the manufacturer's installation instructions or certificate of compliance to confirm that the Ubbink Rolux® concentric vent system is approved for your direct vent tankless water heater. The tankless water heater installation instructions take precedence over this document.
Installation Requirements Installation and service of Ubbink Rolux® concentric vent systems must be performed by a qualified installer, service agency or the gas supplier. Approvals/codes The installation must conform with local codes or, in the absense of local codes, the National Fuel Gas Code, ANSI Z223.1/NFPA 54 and/or CSA B149.1, Natural Gas and Propane Installation Code. The maximum vent length, as stated in the water heater installation instructions and these instructions, should never be exceeded.
Recommended vent/air intake terminal position Terminals should be so positioned as to avoid products of combustion entering openings into buildings or other flues or vents H B ED FIX ED S O E L L C AB X ER OP B D E C V V B L V F ED FIX ED OS CL LE AB ER OP B V V B V I M X V K DETAIL INSIDE CORNER J G A V V A B CAUTION Maintain 12” of clearance above the highest anticipated snow level or grade or whichever is greater. Please refer to your local codes for the snow level in your area.
General Installation Instructions Joint connection Vent connections must be firmly pressed together so that the gaskets form an airtight seal. To complete the joint connection, secure with three #8x1/2" sheet metal screws. Secure the vent to the wall or ceiling with pipe clamps or perforated hanger iron. Coping with condensation Vent lengths greater than 5ft. should pitch a minimum 1/4"/ft. (1°) to the appliance. Note: see exception under Condensate on page 4.
B Condensate drain B D A D Condensate can damage the water heater, please read carefully page 4 in this installation manual. male appliance top C female appliance top C To prevent condensate from draining back to the appliance, a condensate collector (B) and trap (C) should be used. The trap must maintain 3" of fluid and the drain tube must pitch down from the appliance. Annually inspect the collector and trap for obstructions and fluid content in the trap.

1 Installation Instructions Rolux® Vertical Discharge Vent System Identify the vent location NOTE Cover the top of the heater to prevent debris from entering. Determine the location where the roof discharge terminal will be installed. Taking into account the angle of the roof, cut the hole with a dimension that allows the vertical discharge roof terminal to be installed (6"x6" hole for flat roof, 9"x6" hole for 12/12 pitch, or 12"x6" hole for 16/12 pitch).
3 Mounting the vent system Vent connections must be firmly pressed together so that the gaskets form an airtight seal. Secure the system with the supplied vent pipe clamp or perforated hanger iron.
