CHAPTER 2
Installation
2.1 — Application
Electrical power and control circuit power is 115 volt, single phase, 60 cycle. Refer to the electrical schematic diagram
shipped with the burner. The schematic is attached to the inside of the control panel cover. Power connections are made
at the control panel. Wiring from the panel to burner mounted components is completed at the factory. Wiring from the
burner panel to boiler controls, low water controls, and remotely located fuel valves is completed by the installer.
2.2 — Draft Conditions
Automatic over-fire draft control or barometric draft regulators are not usually required except where the system has a
tall chimney. The exact height of a chimney requiring draft control is indeterminate, but draft regulation is seldom
needed for chimneys less than 50 feet high, especially with Scotch Marine or sealed firebox boilers. Gas piping
instructions are described in this chapter.
2.3 — Combustion Air Supply
The space in which a burner operates must be supplied with adequate fresh air for combustion and ventilation purposes.
Fresh air supply must meet or exceed all code requirements. Consult with insurance carrier and/or local authorities for
specific regulations.
The boiler room pressure must be at least equal to the outdoor atmospheric pressure. Where fan ventilation is used, air must
be forced into the boiler room. Never exhaust air from the boiler room. Adjoining areas having exhaust fans must be
positively isolated from the boiler room.
