Pre-installation Checklist
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

adjustments are based on 60 Hz motors at 3450 rpm.
Derate fi ring capacity 20% when using 50 Hz motors.
Consult factory for specifi c application data.
