COMBUSTION AIR SYSTEM
AIR OPENINGS TO COMBUSTION AREA MUST NOT BE
OBSTRUCTED. USE THE INFORMATION BELOW TO ENSURE THAT
ADEQUATE COMBUSTION AIR IS MAINTAINED.
2.1. COMBUSTION AIR REQUIREMENTS
Innovation and ReCon water heaters require the following combustion air volumes when operated at
full capacity:
INNOVATION
RECON
INN600 – 130 SCFM (2.8 m
3
/min)
ReCon 1000 – 215 SCFM (6.1 m
3
/min)
INN800 – 170 SCFM (4.8 m
3
/min)
INN1060 – 225 SCFM (6.4 m
3
/min)
INN1350 – 285 SCFM (8.1 m
3
/min)
INN1400 – 285 SCFM (8.1 m
3
/min)
These flows MUST be accommodated. Air supply is a direct requirement of NFPA, CSA B149.1-10
(Canada) and local codes that should be consulted for correct design implementation.
NOTES:
1. The combustion air must be free of chlorine, halogenated hydrocarbons or other chemicals that
can become hazardous when used in gas-fired equipment. Common sources of these
compounds are swimming pools, degreasing compounds, plastic processing, and refrigerants.
Whenever the environment contains these types of chemicals, combustion air MUST be
supplied from a clean area outdoors for the protection and longevity of the equipment and
warranty validation.
2. When calculating free area using louvers and grilles, the required size of the openings for
combustion, ventilation, and dilution air shall be based on the total free area of each opening.
•
If the free area through a designed louver or grille is known, it shall be used in calculating the
size of opening required to provide the free area specified.
•
If the louver and grille design free areas are
not
known, the following will be assumed: For
wooden louvers a 25 percent free area; for metal louvers and grilles a 75 percent free area
opening.
3. When terminating the combustion air through the roof:
•
The combustion air inlet must be 3 ft. (0.9 m) below any vent outlet within 10 ft. (3 m) (see
Figure 10).
•
The combustion air inlet must also face away from the vent outlet (see Figure 10).
4. All inlet air ducts must be sealed air tight.
5. The boiler/heater room must not be under negative pressure under any circumstances (even when
the combustion air is direct ducted). If necessary, ventilate the room to prevent this condition from
occurring.
