3.3.2 Vertical Venting (Category I)
All indoor installations and outdoor shelter installations
require an approved 4 inch double-wall appliance adapter
and increaser to be connected to the JXi 4-inch flue collar
for Type B installations. Increasers are available in steps
up to a maximum of four sizes larger. 4 inch double-
wall appliance adapters and increasers can be obtained
from manufacturers such as Amerivent or Duravent
®
(see Section 2.3 for detailed specifications). All vent
installations must be made in accordance with local, state,
or provincial codes and with:
• National Fuel Gas Code ANSI
®
Z223.1 (NFPA
®
54),
latest edition; pay particular attention to the chapter
addressing “Venting of Equipment.” Applicable
provisions of additional applicable local building
codes may also need to be followed.
• Canada CAN/CSA B149.1.
Vent the JXi heater vertically in a negative pressure (non-
positive draft) system in accordance with the National
Fuel Gas Code NFPA 54 / ANSI Z223.1 or the Canadian
Natural Gas and Propane Installation Code, CAN/
CSA-B149.1. A type B double-wall vent connector is
required. The heater must not be used to support the vent
pipe.
Note that the tables for fan-assisted appliances include
both maximum and minimum vent loading figures in the
NFPFA 54. The primary purpose of the maximum ratings
are to ensure that the vent operates with negative pressure
throughout its length. The minimum rating refers to the
firing rate.

Connect the 4 inch double-wall appliance adapter
for category I or vent connector for category III to
the flue collar and fasten with three (3) sheet metal
screws, as shown in Figure 7).
NOTE:
It is important to position the three screws so the seal
in the flue collar is not compromised. Begin with first
screw at 3 o’clock position from top of the flue collar
seam. Install screws 2 and 3 in positions 120 degrees
apart (as shown in Figure 7).
