It is the responsibility of the installing contractor to see that all controls are correctly installed and
are operating properly when installation is complete including verifying that the limit sensor is fully
installed (seated in bottom of Well).
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 NOT suitable for installation on combustible ooring, unless installed with a combustible
oor shield constructed in accordance with NFPA 31. A concrete pad is not sufcient to protect
combustible ooring. Concrete over wood joists is considered combustible ooring.
DO NOT install boiler on carpeting.
When boiler is installed on concrete which is over a material that is subject to melting (PVC, PEX
radiant tubing, etc.) a combustible oor shield must be used.
DO NOT operate on masonry oors, which may contain moisture.
DO NOT tamper with or alter the boiler or controls.
Retain your contractor or a competent serviceman to assure that the unit is properly adjusted and
maintained.
Have Firetubes cleaned at least once a year - preferably at the start of the heating season to remove
soot and scale. The inside of combustion chamber should also be cleaned and inspected at the same
time.
When cleaning this boiler, DO NOT damage combustion chamber. If damaged, combustion chamber
must be replaced immediately.

WARNING
This boiler contains very hot water under 12 - 15 PSI 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.
High water temperatures increase the risk of scalding injury. If this boiler is equipped with a tankless
heater for domestic water supply, a ow regulator and automatic mixing valve must be installed properly
in tankless heater piping. See Piping and Trim Sections of this manual for details.
This boiler needs fresh air for safe operation and must be installed so there are provisions for adequate
combustion and ventilation air.
This 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 interior of the chimney ue must be inspected and cleaned before the start of the heating season for
any obstructions. A clean and unobstructed chimney ue is necessary to allow noxious fumes that could
cause injury or loss of life to vent safely and will contribute toward maintaining the boiler's efciency.
DO NOT operate boiler with the absence of an approved vent system.
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.
All boilers equipped with burner swing door have a potential hazard which if ignored can cause severe
property damage, personal injury or loss of life. Before opening swing door, turn off service switch to
boiler to prevent accidental ring of burner outside the combustion chamber. Be sure to tighten swing
door fastener completely when service is completed.

A. INSPECT SHIPMENT carefully for any signs of
damage.
1. All equipment is carefully manufactured, inspected
and packed. Our responsibility ceases upon delivery
of crated boiler to the carrier in good condition.
2. Any claims for damage or shortage in shipment
must be led immediately against the carrier by the
consignee. No claims for variances from, or shortage
in orders, will be allowed by the manufacturer unless
presented within sixty (60) days after receipt of
goods.
B. LOCATE BOILER near nal position before removing
crate. See Figures 1A thru 1C. Using hand truck or pipe
rollers under skid, move boiler into position along side
installation site.
CAUTION
DO NOT drop boiler. DO NOT bump boiler jacket
against oor.
1. LOCATE so that vent pipe connection to chimney
will be short and direct.
2. BOILER IS NOT SUITABLE FOR
INSTALLATION ON COMBUSTIBLE FLOOR
unless installed with a Combustible Floor Shield
constructed in accordance with NFPA31.. Boiler
cannot be installed on carpeting.
3. FOR BASEMENT INSTALLATION, provide
a solid elevated base, such as concrete, if oor is
not level, or if water may be encountered on oor
around boiler.
WARNING
Do not support boiler by placing blocks at the
four (4) corners of the boiler.
Boiler base must be evenly supported under
entire base.
Concrete over wood joists is considered
combustible flooring. Do not operate on
masonry oors, which may contain moisture.
4. PROVIDE SERVICE CLEARANCE of at least
48” clearance from front jacket panel for servicing
and removal of front tankless heater.
5. For minimum clearances to combustible materials.
See Figure 2.
NOTICE
Clearance to venting is for single wall vent
pipe. If Type L vent is used, clearance may be
reduced to the minimum required by the vent pipe
manufacturer.

installations.
NOTE 3: For reduced clearances to combustible material,
protection must be provided as described in the ANSI/NFPA
31 standard.
II: Pre-Installation (continued)
C. PROVIDE COMBUSTION AND VENTILATION
AIR. Local and National Codes may apply and should
be referenced.
WARNING
Adequate combustion and ventilation air must
be provided to assure proper combustion and
to maintain safe ambient air temperatures.
DO NOT install boiler where gasoline or other
ammable vapors or liquids, or sources of
hydrocarbons (i.e. bleaches, fabric softeners,
etc.) are used or stored.
1. Determine volume of space (boiler room). Rooms
communicating directly with the space in which
the appliances are installed, through openings not
furnished with doors, are considered a part of the
space.
3
Volume(ft
2. Determine total input of all appliances in the space.
Add inputs of all appliances in the space and round
the result to the nearest 1000 BTU per hour.
3. Determine type of space. Divide Volume by total
input of all appliances in space. If the result is
greater than or equal to 50 ft3/1000 BTU per hour,
then it is considered an unconned space. If the
result is less than 50 ft3/1000 BTU per hour then the
space is considered a conned space.
4. For boiler located in an unconned space of a conventionally constructed building, the fresh
air inltration through cracks around windows
and doors normally provides adequate air for
combustion and ventilation.
5. For boiler located in a conned space or an
unconned space in a building of unusually tight
construction, provide outdoor air.
Outdoor air may be provided with the use of two
permanent openings which communicate directly or
by duct with the outdoors or spaces (crawl or attic)
freely communicating with the outdoors. Locate one
opening within 12 inches of top of space.
) = Length(ft) x Width(ft) x Height(ft)
Locate remaining opening within 12 inches of
bottom of space. Minimum dimension of air opening
is 3 inches. Size each opening per following:
a. Direct communication with outdoors.
Minimum free area of 1 square inch per 4,000
BTU per hour input of all equipment in space.
b. Vertical ducts. Minimum free area of 1 square
inch per 4,000 BTU per hour input of all
equipment in space. Duct cross-sectional area
shall be same as opening free area.
c. Horizontal ducts. Minimum free area of 1
square inch per 2,000 BTU per hour input of all
equipment in space. Duct cross-sectional area
shall be same as opening free area.
Alternate method for boiler located within
conned space. Use indoor air if two permanent
openings communicate directly with additional
space(s) of sufcient volume such that combined
volume of all spaces meet criteria for unconned
space. Size each opening for minimum free area
of 1 square inch per 1,000 BTU per hour input
of all equipment in spaces, but not less than 100
square inches.
6. Louvers and Grilles of Ventilation Ducts
a. All outside openings should be screened and
louvered. Screens used should not be smaller
than 1/4 inch mesh. Louvers will prevent the
entrance of rain and snow.
b. Free area requirements need to consider the
blocking effect of louvers, grilles, or screens
protecting the openings. If the free area of the
louver or grille is not known, assume wood
louvers have 20-25 percent free area and metal
louvers and grilles have 60-75 percent free area.
c. Louvers and grilles must be xed in the open
position, or interlocked with the equipment to
open automatically during equipment operation.
