Efficient MF three-pass design, available in 10 horse power to 300 horse power models. Our Firebox boilers are fitted with a forced draft flame retention burner that results in an efficiency of over 80%. This boiler-burner combination gives reliable operation with minimum maintenance.
Design:
· Efficient 3-Pass firebox design incorporating the wetback principal
· Oil fired burner standard but can be modified for other fuel sources
· ASME code constructed and stamped for 15 psi steam/30 water
· Our boilers can be custom built to ASME code for higher pressures if desired
· Conforms to interprovincial regulations
· All welded construction is used throughout
· Steel channels form the base of the boiler
· Steel skids and lifting eyes
· Large firebox volume insures quiet operation through the complete cycle
· Large furnace volume for ultimate combustion efficiency
· Insulated with 2 inches of mineral wool
· Jacket is 16 gauge sheet metal finished with a hard finish enamel
· Easy access to fireside surfaces
· Ample waterside cleanout openings
· Fully automatic operation
· UL listed forced draft burners
· UL listed controls and trim
· Factory test fired
· Flame observation ports, front and rear
Burner:
· The complete burner is listed with CSA and Underwriter’s Laboratories
· Forced draft type, factory assembled, wired and tested
· Equipment includes direct driven blower that supplies combustion air and forces products of combustion through the boiler and stack
· Totally enclosed hinged, 14 gauge electrical control cabinet, containing a combustion safeguard control system, motor starter(s), control circuit transformer to 115 volts
· Manual on-off switch, numbered terminal strips, flame observation port, control fuse and internal access
· Upon interruption of electrical power, the burner will recycle before fuel valve opens
· Upon flame failure, the electronic combustion control shall lockout and require manual reset
· Burner motor will not run during lockout condition
Installation:
· Bring the electrical supply to the control panel
· Hook up oil, steam and return lines
Stack:
· Through pressurized firing, only a stub stack is required to carry off the products of combustion
Steam boiler fittings:
· Includes safety valve, steam gauge, siphon cock and drain, gauge glasses complete with rods, low water cutoff and pump control, pressure controls and tube cleaner
Water boiler fittings:
· Equipped with relief valve, temperature/pressure gauge, high/low operating controls, low water cutoff and tube cleaner
