The heater must be completely isolated and
protected from any source of corrosive chemical fumes
such as those emitted by trichlorethylene, perchloro-
ethylene, chlorine, etc.
WARNING
Do not store any chemicals, cleaners, or other cor-
rosive material near combustion air openings or in
the room. Avoid locating appliance vents in the vi-
cinity of combustion air openings. Failure to prevent
corrosive materials from mixing with combustion air
can result in reduced heater life and unsafe heater
operation.
AVERTISSEMENT
Ne pas entreposer ni utiliser d'essence ni d'autres
vapeurs ou liquides inflammables à proximité de cet
appareil ou de tout autre appareil.
3.2
Exhaust Venting
When converted to indoor and outdoor shelter
venting configuration, the LXi heater has a vent collar
fitting for attachment to the venting for Category I
vertical venting. The diameter of the vent collar and,
thus, the minimum diameter of the vent pipe to be used
is determined by the model of heater installed and the
type of venting.
The only correct procedure for vent
pipe sizing is to do so in accordance with Table 4
and the applicable installation code as stated in the
following "Warning" warning.
Note that with hori-
zontal Category III type vent installations, the venting
may be smaller than the vent collar for Category I
vertical venting. See Table 4. Category III vent collars
are available separately.
Table 3. Air Openings to Outside
NOTE
Except for the combustion air openings
requirements, in Canada, follow Canadian
Standard, CAN/CSA-B149.1 or local codes.
Follow the requirements of Table 3 for the
minimum combustion air openings required.
Exhaust Fans or Vents:
Any equipment
which exhausts air from the room where the heater
is installed can deplete the combustion air supply or
reverse the natural draft action of the venting system.
This could cause flue products to accumulate in the
room. Additional air must be supplied to compensate
for such exhaust.
The information in Table 3 is not applicable in
installations where exhaust fans or blowers of any type
are used. Such installations must be designed by quali-
fied engineers.

1. Use approved
roof jack.
Figure 7. Indoor Installation Venting (USA), or Outdoor Shelter (Canada)
Required Net Free Open Area*
for Combustion Air Openings
*Area indicated is for one (1) of two (2) openings; one (1) at
floor level and one (1) at the ceiling, so the total net free area
would be double the figures indicated. For special conditions,
refer to NFPA54 ANSI Z223.1.
The requirements in this table for combustion air openings
MUST be followed for all Canadian installations also.
The
minimum allowable combustion air openings in the Canadian Na-
tional Standards CAN/CSA B149.1 are not adequate for proper
operation of the LXi heaters.
NOTE: If using screens and/or metal louvers, compensate by adding
50% additional area to each opening. If using wood louvers each
opening must be at least four (4) times the area indicated in the table
above.
