INSTALLATION INSTRUCTIONS FOR 2”AND 3”
PVC LOW PROFILE VENT TERMINATION KITS.
SYSTEM 1738
®
(UL 1738 / ULC S636)
1. Refer to the appliance manufacturer’s installation
instructions to ensure that the low profile side wall
termination kit is permitted for use. The IPEX Low
Profile side wall termination kit is fully certified to
UL 1738 and ULC S636.
2. In the USA, this termination is for use with only
System 1738 products unless mixing of components
from different vent manufacturers is allowed by the
authority having jurisdiction.
3. In Canada, this kit is for use with only System 636
products.
System 1738 PVC Low
Profile vent kits are made
from an engineered PVC
compound certified to
both UL 1738 and ULC
S636 standards and are
rated to a maximum
temperature of 149
o
F.
The vent termination must
maintain all termination
clearances and be
installed in accordance with local building code and
NFPA 54 / ANSI Z223.1 National Fuel Gas Code in the
United States and CSA B149.1 National Fuel Gas Code in
Canada (see figure 1).

Installation Procedure
1. When locating the penetration of the vent and air
pipe, ensure the termination is properly oriented
as shown in Figure 2 and ensure that it maintains
minimum clearance requirements as shown in Figure 1.
For multiple vent terminations, ensure that a minimum
clearance of 12 inches is maintained between edge
of air inlet and adjacent vent outlet and that all vent
pipes and air inlets terminate at the same height
to avoid the recirculation of flue gases and the
possibility of causing severe personal injury, death, or
substantial property damage. (see Figure 4)
2. When installing the vent termination in a vertical
configuration, ensure the vent piping is located above
the air inlet piping. This will avoid the risk of flue gas
products recirculating into the air inlet and building.
(see Figure 2).
3. Once the installer has determined the termination
location, cut 2 holes in the wall large enough
to accommodate the pipe. Pipe diameters and
distance between hole centers can be found in
Table 2 or by using the template on reverse.
4. Slide both the intake and vent pipe through the
holes. Solvent weld both pipes to the Base of
the vent termination kit (see Figure 3) following
the solvent welding procedures outlined in the
System1738 (United States) and System 636 (Canada)
Installation Methods Guide found at system1738.com
and system636.com.
5. To fasten the Base to the wall, use the supplied
screws and anchors. A 3/16” diameter x 1-3/16” deep
hole, will need to be drilled for the anchors. Locate
and mark the anchor hole using the Base as a
template and then drill the required holes.
6. Screw the Cap to the Base using the supplied
screws.
7. Once the vent termination and pipe are secured,
the wall penetrations will need to be sealed from the
interior using a PVC-compatible sealant material.
