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.
Always refer to the appliance installation instructions before proceeding with the
installation of this product.

3
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.
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. (1,5 m)
- Slope horizontal venting 1/4 inch per foot (25 mm/m) either toward the appliance with a
condensate collector or toward the exhaust terminal (Ubbink prefers pitching the vent
1/4 inch per foot (25mm/m) 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 (25 mm/m) 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.

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. The Ubbink Rolux White Vent extension material is
primarily designed for indoor use. If used outdoors the material should be protected for
UV-radiation (direct sunlight).

General Installation Instructions
Joint connection
Vent connections must be firmly pressed
together so that the gaskets form an
airtight seal. To ensure optimum joint con-
nection, it is recommended to secure with
three #8x1/2” self tapping screws. Secure
the vent to the wall or ceiling with pipe
clamps or perforated hanger iron.
Vent connections extending beyond the
outside of a building or structure should
be enclosed to protect seals and gaskets.
Coping with condensation
Horizontal vent lengths greater than 5ft.
(1,5m) should pitch a minimum 1/4”/ft.
(25mm/m) or (1°) to the appliance.
Appliance connection (female appliance top)
Installations with a female appliance top
do not need an appliance adapter. Simply
insert the male end of a vent component
into the female appliance top.
Condensate drain
Condensate can damage the water
heater, please read carefully page 3
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” (75 mm)
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.
Remove the drain cap and install a condensate trap per the installation instructions.

WARNING
Improper installation of vent system and components, or failure to follow
all installation instructions, can result in property damage or serious injury.
Shortening of vent extensions
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.

Rolux®Vertical Discharge Vent System
Identify the vent location
Determine the location where the roof dis-
charge 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” 150x150 mm hole for flat roof,
- 9”x6” 225x150 mm hole for 12/12 pitch (45°)
- 12”x6” 300x150 mm hole for 16/12 pitch
(55°).
Cut to fit
The terminal can be
shortened by cutting
both the inside and
outside pipes with
the same length X.
Cover the top of the heater
to pr event debris from entering .

Installation of the raised horizontal cover
- Position the hole at the top of the enclosure over
the vent termination, slide the cover to the wall.
- The cover should be positioned in a vertical
position.
- If needed water-proof silicon sealant can be
used to seal the ridge at the top of the cover.
- Assemble the cover to the wall with provided
screws and wall anchors (optional) depending on
wallstructure.
- The screw positions are clearly marked on the cover.
If needed the cover can be cut in the middle and slid
together to reduce the overall length of the cover.
Note: Do not position any part of the cover or
vent system below grade.
