Concealed damage – If you discover damage to the burner or
controls during unpacking, notify the carrier at once and file the appropriate claim forms.
High altitude installations – Accepted industry practice requires no derate of burner capacity up to 2000 feet above sea level. For altitudes higher than 2000 feet, derate the burner capacity 2% for each 1000 feet above the 2000 feet.
50 Hz motors – The burner ratings, air settings and other adjustments are based on 60 Hz motors at 3450 rpm. Derate firing capacity 20% when using 50 Hz motors. Consult factory for specific application data.
Pre-installation Checklist
Indoor Installation
Protect against Dust and
Moisture
Wet or dusty environments could lead to blocked air passages, corrosion damage to components, impaired combustion performance and result in asphyxiation, explosion or fire.
yThis burner is designed for clean, dry installations.
yElectrical controls are not protected against rain or sprayed liquids.
yKeep the installation clear of dust, dirt, corrosive vapors, and moisture.
yProtective covers and more frequent maintenance may be required.
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 confined spaces, the room must have an air opening near the top of the room, plus one near the floor, each with a free area at least one square inch per 1000 Btu/hr input for all
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 flue gas vent system must be in good condition and must comply with National Fuel Gas Code ANSI Z223.1 (NFPA 54) and all other applicable codes having jurisdiction for vent construction, capacity, and sizing.
