INDOOR INSTALLATIONS
Combustion Air Supply
• All indoor installations must have
openings to outside air for combustion
and ventilation from the inside of the
building.
• As outlined in ANSI® standard Z223.1
(NFPA® 54), the room in which the
heater is installed should have two
permanent air supply openings: (1)
within 12 inches (305 mm) of the
ceiling, and (2) within 12 inches (305
mm) of
the floor.
• All air from outdoors should have a net
free area, as shown in the table (right).
If using screens or metal louvers, add
additional area. Consult the specific
louver manufacturer for restriction
specifications as different louvers will
have varying restrictions.
* Area indicated is for one of two openings:
(1) 12ʺ from floor level, and (2) 12ʺ from ceiling level.

For detailed information, refer to the complete installation and owner’s manual.
• Check supply pressure and local code
requirements before proceeding with
installation.
• Consider pipe fittings when
determining gas pipe sizing.
• Larger pipe size can be used if
required by local code.
• It is critical that the incoming gas
supply pressure at the heater is
within the maximum and minimum
pressure requirements. If the range
of acceptable supply pressure is not
provided, the gas supply system to
the heater must be modified to meet
pressure requirements.
• The gas shut off valve must be
installed in an accessible location
within six (6) feet of the heater.
• Do not use CSST or any flexible
gas piping.
GAS LINE SIZING
* Numbers are for natural gas (0.65 Sp. Gr.) based on 1/2 inch (3.45 kPa) water column pressure drop. Check
supply pressure with a manometer, and local code requirements for variations. For LP gas, reduce pipe
diameter by one size, but maintain a minimum 3/4 inch diameter.
For specific requirements:
(1) Natural gas heaters, refer to NFPA® 54.
(2) Propane heaters, refer to NFPA 58.
