2. Install a 4 inch double-wall appliance adapter and
an increaser (see Section 3.3.1).
3. Following the vent connector's manufacturer
instructions attach the vent pipe to the increaser
and further secure them with sheet metal screws.
Before connecting, wet a clean cloth or paper
towel with rubbing alcohol and wipe the socket
of the vent body. Dry with a different clean cloth.
Vent piping must be adequately supported with no
low spots or sagging that could allow condensate
to collect. The heater must not be used to support
the vent pipe. Horizontal runs must be sloped
upwards away from the heater to a vent terminal
at a minimum of 1/4 " per horizontal foot (2
cm/m).
4. Install the vent pipe so it can expand and contract
freely with temperature changes.
Note: Do not run the heater vent into a common
vent with any other appliance.

3.3.3 Vertical or Horizontal Venting

(Category III)
When the installation requires horizontal venting in excess
of what is allowed for Category I installations or calls
for horizontal discharge, the JXi may be installed with a
Category III venting system.
Vent the heater either vertically or horizontally
using Al29-4C stainless steel components. Consult
®
manufacturers such as Z-Flex
approved components. Venting materials must comply
with UL 1738 for Category III, Special Gas Vent.
®
In Canada, the venting materials must be ULC S636
compliant. Vent piping must be adequately supported with
no low spots or sagging that could allow condensate to
collect.
The heater must not be used to support the vent pipe.
Horizontal runs must be sloped upwards away from the
heater to a vent terminal at a minimum of 1/4 inch per
horizontal foot (2 cm/m).
It is recommended that vent runs over 18 feet be insulated
to reduce condensation and/or use a condensate trap in
the vent run close to the heater, especially in certain cold
climate installations.
See Table 3 for recommended vent size and run lengths
without elbows. For each elbow installed, reduce the run
length by 12 feet (3.7m)

IMPORTANT NOTE
In the Commonwealth of
Massachusetts, additional requirements, covered in
document CMR 248 5.00, which supersede some of
the requirements of ANSI Z223.1 (NFPA 54) apply to
Side Wall Horizontally Vented appliances. If installing
this product using an approved side-wall horizontal
vent system in the Commonwealth of Massachusetts,
be sure to adhere to these additional requirements.
These requirements include verbiage that says that
the property owner is to ensure that Carbon Monoxide
