NOTICE
This boiler has a limited warranty, a copy of which is included with the boiler.
The warranty for this boiler is valid only if the boiler has been installed, maintained and operated in
accordance with these instructions.
Surface rust on cast iron sections may be attributed to the manufacturing process as well as condensation
during storage. Surface rust is normal and does not affect the performance or longevity of a boiler.
All boilers must be installed in accordance with National, State and Local Plumbing, Heating
and Electrical Codes and the regulations of the serving utilities. These Codes and Regulations
may differ from this instruction manual. Authorities having jurisdiction should be consulted
before installations are made.
In all cases, reference should be made to the following Standards:
USA BOILERS
A. Current Edition of American National Standard ANSI/NFPA 31, “Installation of Oil
Burning Equipment”, for recommended installation practices.
B. Current Edition of American National Standard ANSI/NFPA 211, “Chimneys, Fireplaces,
Vents, and Solid Fuel Burning Appliances”, For Venting requirements.
C. Current Edition of American Society of Mechanical Engineers ASME CSD-1, “Controls and
Safety Devices for Automatically Fired Boilers”, for assembly and operations of controls
and safety devices.
D. All wiring on boilers installed in the USA shall be made in accordance with the National
Electrical Code and/or Local Regulations.

DANGER
DO NOT store or use gasoline or other ammable vapors or liquids in the vicinity of this or any other appliance.
WARNING
Improper installation, adjustment, alteration, service or maintenance can cause property damage, personal
injury or loss of life. Failure to follow all instructions in the proper order can cause personal injury or
death. Read and understand all instructions, including all those contained in component manufacturers
manuals which are provided with the appliance before installing, starting-up, operating, maintaining or
servicing this appliance. Keep this manual and literature in legible condition and posted near appliance
for reference by owner and service technician.
This boiler requires regular maintenance and service to operate safely. Follow the instructions contained
in this manual.
Installation, maintenance, and service must be performed only by an experienced, skilled and knowledgeable
installer or service agency.
All heating systems should be designed by competent contractors and only persons knowledgeable in
the layout and installation of hydronic heating systems should attempt installation of any boiler.
Installation is NOT complete unless a pressure relief valve is installed into the 3/4" tapping located in top
left corner of front section - See Figure 1 and "Water Boiler Piping" Section of this manual for details.
It is the responsibility of the installing contractor to see that all controls are correctly installed and are
operating properly when the installation is complete including verifying that the limit sensor is fully installed.
Failure to properly install Limit Sensor may result in property damage, personal injury or loss of life
due to elevated operating temperatures and/or pressures.
This boiler is suitable for installation on combustible ooring. DO NOT install boiler on carpeting.
DO NOT tamper with or alter the boiler or controls.
Inspect ueways at least once a year - preferably at the start of the heating season. The inside of
the combustion chamber, the vent system and boiler ueways should be cleaned if soot or scale has
accumulated.
When cleaning this boiler, take precaution to avoid damage to target wall, chamber liner or burner mounting
plate insulation. If damaged, or if there is evidence of previous damage, replace the damaged insulation
piece(s) immediately.
Oil Burner and Controls must be checked at least once a year or as may be necessitated.
DO NOT operate unit with jumpered or absent controls or safety devices.
DO NOT operate unit if any control, switch, component, or device has been subject to water.
Boiler materials of construction, products of combustion and the fuel contain alumina, silica, heavy metals,
carbon monoxide, nitrogen oxides, aldehydes and/or other toxic or harmful substances which can cause
death or serious injury and which are known to the state of California to cause cancer, birth defects and
other reproductive harm. Always use proper safety clothing, respirators and equipment when servicing
or working nearby the appliance.

WARNING
This boiler contains very hot water under high pressure. DO NOT unscrew any pipe ttings nor attempt
to disconnect any components of this boiler without positively assuring the water is cool and has no
pressure. Always wear protective clothing and equipment when installing, starting up or servicing this
boiler to prevent scald injuries. DO NOT rely on the pressure and temperature gauges to determine the
temperature and pressure of the boiler. This boiler contains components which become very hot when
the boiler is operating. DO NOT touch any components unless they are cool.
This boiler must be properly vented. The boiler must be connected to an approved chimney or vent
system in good condition. Serious property damage could result if the boiler is connected to a dirty or
inadequate chimney or vent system. The chimney must be inspected for any obstructions and cleaned
prior to each heating season. A clean and unobstructed chimney ue is necessary to produce the minimum
draft required to safely evacuate noxious fumes that could cause personal injury or loss of life. DO NOT
operate boiler with the absence of an approved vent system. Evidence of loose debris and or condensate
induced stains at the base of the chimney ue, connector or smokepipe joints may be signs of condensing
ue gases. Flue gas condensate is corrosive, which requires special consideration and must be addressed
immediately. Refer to "Venting (Natural Draft - Chimney)" listed in Table of Contents below .
This boiler needs fresh air for safe operation and must be installed so there are provisions for adequate
combustion and ventilation air.
This boiler is supplied with controls which may cause the boiler to shut down and not re-start without
service. If damage due to frozen pipes is a possibility, the heating system should not be left unattended in
cold weather; or appropriate safeguards and alarms should be installed on the heating system to prevent
damage if the boiler is inoperative.
This boiler is designed to burn No. 2 fuel oil only. DO NOT use gasoline, crankcase drainings, or any
oil containing gasoline. Never burn garbage or paper in this boiler. DO NOT convert to any solid fuel
(i.e. wood, coal). DO NOT convert to any gaseous fuel (i.e. natural gas, LP). All ammable debris, rags,
paper, wood scraps, etc., should be kept clear of the boiler at all times. Keep the boiler area clean and
free of re hazards.
