Installation & Operation Manual
4.3.2 Direct Air Intake
In certain applications it may be necessary to supply
intake air directly to the heater. You will need to order
and install the direct air conversion R-Kit R0724600.
A total equivalent length of 50 ft (15 m) of 3 in (75 mm)
PVC tubing can be used to bring the intake air directly to
the blower input. Please be aware that each elbow used
will account for 12 ft (3.6 m) of length.
For ease of access, remove the rear and top panels.
a
Loosen the two screws securing the air orice and screen
in place. Remove the air pressure switch and gas valve hose
from the air orice.
b
Remove the air orice, separate and dispose
of the orice screen.
c
Align the orice adapter with the orice tabs and secure
with four screws.
d
Dry t the 3 in (75 mm) PVC tubing into the orice
adapter. Mark screw hole locations with a pen. Remove and
drill pilot holes in the PVC. Fit the PVC into the orice
adapter, align the holes and secure with four screws
e
Reinstall the air orice and air hoses.
f
Install the new rear panel over the PVC and secure with
four screws.
4.3.3 Exterior Venting And Air Intake
The JXI must be vented to the outdoors. It must not be
vented in common with any other appliance, even if that
appliance is of the condensing type. Common venting
can result in severe corrosion of the JXI or of the other
appliances or their venting, or escape of combustion
product gases through such appliances or vents. Do not
vent the JXI to a replace chimney or building chase.
Combustion air ducting, when provided, must not be
shared with any other appliance or with another JXI.
Doing so may result in ow of air through the other
appliances instead of directly from the outdoors.
The combustion air intake and vent outlet must be located
exterior to the building and in the same pressure zone
- i.e. both through the roof or both through a side wall.
The vent terminal must be located in accordance with
local codes, as applicable, and in accordance with the
following:
• Locate the vent terminal so that it will not be
damaged by pedestrians and other trafc, and so that
the discharge is not offensive. The National Fuel Gas
Code requires a through-wall vent terminal be at least
7 feet (2.13 m) above grade if located at a public
walkway.
• Locate the vent terminal so the vent exhaust does not
settle on building surfaces and other nearby objects.
Vent products may corrode such surfaces or objects.
• Locate the vent terminal at a sufcient horizontal
distance from any gas or electric metering, regulating
or relief equipment. In the United States, this distance
must be at least 4 feet (1.22 m). In Canada, it must be
at least 10 feet (3.05 m).
• Locate the vent terminal at a sufcient horizontal
distance from any building opening. Take special
care to assure that combustion products do not enter
a building through windows, doors, ventilation inlets,
etc. In the United States, this distance must be at least
4 feet (1.21 m). In Canada, it must be at least 10 feet
(3.04 m).
As shown in Figure 5 and Figure 6, the combustion air intake
and the vent outlet must be installed no closer together than
18 in (45.7cm) and no farther apart than 60 in (1.5m). The
combustion air inlet opening must face downward to prevent
entry of rain or snow. The vent outlet must discharge away
from the combustion air inlet - normally in a horizontal
direction when on a wall and vertically upward when on a
roof. Both should terminate at least 12 in (30.5cm) above the
snow accumulation level. In locations with freezing climate,
extension of the vent pipe outside of the building should be
minimized. The insect screens provided with the heater must be
installed at the combustion air and vent pipe openings as shown
in Figure 10. Insect screens are sized to t the inside of a 5 in
PVC pipe tting. Trim them as necessary for smaller pipe sizes.

For indoor installations the exhaust
must also be converted. Order part

instructions in The JXi Installation
and Operation Manual H0574300,
section 3.3.4 “Indoor and Outdoor
Shelter Exhaust Conversion”.
