Indoor Installation
Combustion Air Supply
The burner requires combustion air and ventilation air
for reliable operation. Assure that the building and/or
combustion air openings comply with the latest edition of
the National Fuel Gas Code ANSI Z223.1 (NFPA 54).
For appliance/burner units in confi ned spaces, the room
must have an air opening near the top of the room, plus
one near the fl oor, each with a free area at least one
square inch per 1000 Btu/hr input for all fuel-burning
equipment in the room.
For Canadian installations, refer to latest edition of
CAN1- B149.1 standard.
If there is risk of the space being under negative
pressure, or of exhaust fans or other devices depleting
available air for combustion and ventilation, the
appliance/burner should be installed in an isolated room
provided with outside combustion air.
Clearances
With the burner installed in the appliance, there must
be adequate space in front of and on the sides of the
burner to allow access and operation. Verify that the
clearance dimensions comply with local codes and with
the appliance manufacturer’s recommendations.
Fuel Gas Supply
Verify that the gas supply piping complies with all
applicable local codes and the latest edition of the
National Fuel Gas Code ANSI Z223.1 (NFPA 54).
Insure that the supply gas pipe size is capable of
providing at least the minimum pressure required to the
burner gas train inlet at the burner’s full capacity rating.
Refer to Table 1.
Flue Vent System
The fl ue gas vent system must be in good condition
and must comply with National Fuel Gas Code ANSI
