Profire D/Series burners are assembled, wired, and tested at the factory. They are listed by the Underwriters Lab-
oratory, CSD-1, NFPA-85, I.R.I., F.M., including the National electrical Code (NEC) and associated insurance
underwriters. Where applicable, the Canadian Gas Association (CGA) B149 and Canadian Standards Association
(CSA) B140 codes shall prevail. Other regulatory agency control options are available.
The operator must be familiar with the individual functioning of all controls to understand the operations and
procedures described in the manual. Identify and locate each item in the illustrations as they are described in the
following sections.
1.2 — Description
The Profire D/Series oil burners are of the low pressure, air atomizing (nozzle) type. Gas burners are of the
peripheral mix type. All burners feature ignition by spark-ignited gas pilot flame. With either fuel, the burner
operates with full modulation. A switch permits changeover from automatic fully modulated firing to manually set
firing at any desired rate between minimum and maximum. Additional safeguards assure that the burner always
returns to minimum firing position for ignition.
D/Series burners are designed for automatic, unattended operation except for periodic inspection and mainte-
nance. After selecting the proper overload settings for the starter, the rest of the control panel components
require little attention except for occasional cleaning.
Only factory authorized burner service personnel should start-up, adjust, or service this equipment.
