The heater must be completely isolated and
protected from any source of corrosive chemical
fumes such as those emitted by trichlorethylene,
perchloroethylene, chlorine, etc.
WARNING
Do not store any chemicals, cleaners, or other
corrosive material near combustion air openings or in
the room. Avoid locating dryer vents in the vicinity of
combustion air openings. Failure to prevent corrosive
materials from mixing with combustion air can result
in reduced heater life and unsafe heater operation.
3.2 Exhaust Venting
The XL-3 heater has a vent collar fitting as part
of the heater's top panel. The diameter of the vent
collar and, thus, the minimum diameter of the vent pipe
to be used is 9 inches. The only correct procedure
for vent pipe sizing is to do so in accordance with
these instructions and the applicable installation
code as stated in the following "Danger"
warning.
DANGER
Vent pipe diameter must be as required by the
National fuel Gas Code Z223.1 or the Canadian
Installation Codes for Gas Appliances CAN 1-B149.1
& 2. Undersize pipe can result in inadequate venting
and oversize pipe can result in vent condensation. In
either case the result can be release of combustion
products to the indoors. This can cause serious
injury or death by carbon monoxide poisoning or
asphyxiation.
3.2.1 Outdoor Installations
For outdoor installations, a factory authorized
vent cap with a 9 inch diameter must be installed and
secured to the vent collar fitting on the top panel of the
heater. Exhaust venting considerations will determine
the placement of the heater (See Section 2.3.4). If the
heater cannot be placed so as to meet the
requirements stated in Section 2.3.4, a vent pipe may
be added to the heater to move the exhaust vent
opening to a position that complies with the
requirements. In all cases, vent pipes must be of the
same diameter as the exhaust outlet of the heater.
Approved vent pipes may be obtained through your
Jandy distributor.
3.2.2 Indoor and Outdoor Shelter
Installations
All indoor installations and outdoor shelter
installations require the addition of a factory approved
barometric draft control. The barometric draft control
must be installed without modification.
All vent installations must be made in accordance
with all local, state or provincial codes and with:
1. Chapter 7, " Venting of Equipment" of the
national Fuel Gas Code, ANSI 223.1 latest
edition, or the applicable provisions of the local
building codes.
2. In Canada, CAN/CGA B149.1 or .2.
Avoid terminating heater vents near air
conditioning or air supply fans. The fans can pick up
exhaust flue products from the heater and return them
inside the building, creating a possible health hazard.
Do not locate the vent terminal where flue
products could strike against building materials and
cause degradation.
Vent opening should be well away from trees or
other obstructions that would prevent free air flow to
and from vent terminal. Do not terminate the vent
under decks, stairways, or carports.
Be sure to support all venting so that connections
will not separate and so that the weight of the vent
pipe does not rest on the heater vent collar. All
connections should be made with rustproof sheet metal
screws. Do not weld or fasten the vent pipe to the
heater vent collar. The heater top must be easily
removable for normal heater service and inspection.
The vent collar outlet is to be connected to an
unobstructed barometric draft control and vent pipe of
the same diameter, terminating in a chimney or directly
outside the building. The vent must terminate at least
two (2) feet (0.6 m) above the highest point of the roof
or other object that is within ten (10) feet (3.0 m) of
the vent termination. The vent pipe must have a listed
vent cap which allows a full equivalent opening for flue
products (see Figure 5).
Install all venting as specified in the latest edition
of the National Fuel Gas Code ANSI Z 223.1 or in
Canada CAN/CGA-B149.1 and B149.2
Run the vent pipe as directly as possible with
minimum turns. Never use a vent smaller than 9"
(23cm). On lateral runs, maintain a minimum pitch of
1/4" (.6cm) per linear foot. If a chimney is used, the
total equivalent straight length of flue piping between
the heater and the chimney should not exceed 75% of
the vertical height of the chimney above the flue pipe
connection. The chimney should be at least 9" (23cm)
diameter. Maintain adequate clearances between the
vent pipe and combustible materials. Check local
codes and the vent manufacturer’s instructions for
proper clearances. The 7" (18cm) dia. inner stack
must be in place.
Any change in the amount of draft in the
combustion chamber can affect the flame
characteristics. An approved barometric draft control
must be used on all indoor installations to maintain a
clean and consistent flame (see Figure 6). When the
system is properly adjusted, the pressure in the stack
below the draft control will be approximately minus
.03" W.C. If this draft pressure cannot be achieved,
the chimney is too short or too small. Take corrective
action.
