A pressure sensitive control, which responds to the steam pressure in the drum, regulates the supply of fuel and air to the burner and provides efficient combustion over the complete modulating range of the boiler. High efficiency is obtained, without thermal shock, over the full operating range, not only at rated output. The built-in safeguards which monitor the main flame and initiate shutdown in the event of loss of flame, as well as the location of the steam drum out of the firing area, assures maximum operational safety of the boiler.

Controls
An integral control panel contains all controls and indicators necessary for the safe operation of the unit. A programmed operating sequence is also incorporated for simplified startup.

Free Start-Up Service
A qualified service representative is on hand for two consecutive days during start-up to assure trouble-free operation and provide on-site operator training

Built to Meet Standards
Every unit is built to ASME Standards, Hartford inspected and National Board registered. Coast Guard, Industrial Risk Insurers, Factory Mutual, American Bureau of Shipping, Lloyds and other approvals are available upon request.

Factory Tested
All units are fire tested for up to three days at the factory, with their individual controls to assure proper operation and to allow for control adjustments, which avoid installation delays.
