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.
Always refer to the appliance installation instructions before proceeding with the
installation of this product.
Introduction
Improper installation of vent system and components, or failure to
follow all installation instructions, can result in property damage
or serious injury.
WARNING

4
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.
Do not use with other vent products
Ubbink Rolux® vent systems must be used throughout the entire vent system.
Do not use vent components from other vent manufacturers when using the Ubbink
Rolux® vent system.
Unless approved by the appliance manufacturer, do not connect this Ubbink concentric
vent into a common vent system.
Inspection
Before installation inspect each vent component for damage and correct seal
placement. Do not attempt to fix or install any damaged vent components.
Condensate
Vertical Termination Installations
• A condensate collector MUST be used on all vertical termination installations.
Horizontal Termination Installations
• A condensate collector MUST be installed on the vent system for any horizontal
termination with a total vertical rise greater than 5 feet.
• Slope horizontal venting 1/4 inch per foot either toward the appliance with a
condensate collector or toward the exhaust terminal (Ubbink prefers pitching the
vent 1/4 inch per foot towards the appliance with a condensate collector).
• If a condensate collector is NOT used for horizontal terminations, it is permitted to
pitch the vent 1/4 inch per foot toward the termination under the following
conditions:
1. The vent system should be inspected annually for signs of damage or condensate
leaks. If the vent system appears damaged the appliance must be turned off and
the vent system repaired.
2. The horizontal termination may not be located above a public walkway, driveway
or area where condensate or vapor could create nuisance or hazard.
3. Ice can develop in regions of cold climate. A 1/4 inch per foot pitch to the
appliance with the use of the condensate collector is recommended (Ubbink can
not be held liable for personal injury or property damage due to ice formation)
Before installation, be sure to identify the appliance top is a male connection or female
connection with integrated condensate collector.

General Installation Instructions
Joint connection
Coping with condensation
Appliance connection (male appliance top)
Appliance connection (female appliance top)
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.
Vent lengths greater than 5ft. should pitch a minimum 1/4"/ft. (1°) to the appliance.
Note: see exception under Condensate on page 4.
For a male appliance top, the first vent component to the appliance must be a vertical
discharge adapter or a horizontal discharge adapter. Never use a vent extension as the first
component to a male appliance top.
Installations with a female appliance top do
not need an appliance adapter or a
condensate collector. Simply insert the male
end of a vent component into the female
appliance top and use the integrated
condensate collector.

Shortening of vent extensions
Condensate drain
The aluminum inside pipe should always extend 0.4” (10 mm) beyond the white outside
pipe on the male end of the vent extension.
Always cut the male end of the vent pipe extension. Do not attempt to cut the
female end.
Pipes overlap by 1.25” (37 mm). Therefore when cutting
to size, add 2 x 1.25 = 2.5” (65 mm) to the extension pipe
length (X) needed for installation.
Deburr the sharp edges, other wise the gaskets might
get damaged, which can result in the system no longer
being air tight.
Improper installation of vent system and components, or failure to
follow all installation instructions, can result in property damage
or serious injury.

Condensate can damage
the water heater, please
read carefully page 4 in
this installation manual.
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. Drain and dispose of condensate per local codes.
Female Appliance Top: The female appliance connection has an integrated condensate
collector. When using this condensate collector remove the drain cap and install a
condensate trap per the installation instructions.
Male Appliance Top: Install a condensate collector and trap as close as possible to the
appliance.

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).
The terminal can be shortened by
removing the components A+B+C,
and then shortening both the inside
and outside pipes with the same
length X.
Re-assemble the terminal by attaching
the components A, B, and C in the
correct order. Tighten component B
securely.
