P/N 240009735, Rev. G [09/30/2016]

4 - BEFORE YOU START

4.1 Installation and Operation

Do not operate unit if any control, switch, components

or devices have been underwater or subject to water

damage�

Before servicing, allow boiler to cool� Always shut off any

electricity and oil supply to boiler when working on it�

Inspect oil line and connections for leaks�

Verify oil burner nozzle is proper size. Over-ring will

result in early failure of boiler sections, and result in a

potentially dangerous situation�

Never vent boiler into enclosed space� Always vent to

the outside� Never vent to another room or inside a

building�

Verify adequate air supply for complete combustion�

Relief valve automatically lifts open when system

pressure exceeds 30 psi� Before installing relief valve

read manufacturer’s instructions� Pipe relief valve to a

safe location� Check with authorities having jurisdiction�

Consider system total water volume, temperature,

initial ll pressure and arrangement when sizing and

installing expansion tank� Improperly installed and

sized expansion tank may result in frequent lifting of

relief valve or other heating system problems� Follow

expansion tank manufacturer guidelines for installation,

and sizing�

Purge heating system of air and gases is critical for

proper circulation and quiet performance� Once the air

is purged, for boiler installations using oat type vents,

air vents should be closed for normal operation� If air

is heard or noticed by loss of heat, purge system and

open vents for short period of time�

4.2 Prior To Installing The Boiler

• Verify you have selected right size boiler with proper

capacity� AHRI rating of boiler selected should be greater

than or equal to calculated peak heating load (heat loss)

for building or area(s) served by boiler and associated

hot water heating systems� Use heat loss calculations

based on approved methods� See Table 6, page 27�

• Boiler must be supplied with proper oil supply and oil

piping, sufcient fresh combustion air, and suitable

electrical supply�

• Connect boiler to suitable venting and piping systems

adequate to distribute heating load�

• Installation is not complete unless pressure relief valve

is installed at 3/4” tapping located at front of unit.

• Thermostat must be properly located and installed

• Failure to pipe boiler correctly may result in excessive

noise or other related problems�

4.3 Existing Water System Evaluation

A good system will prevent oxygen contamination of boiler

water�

Causes of oxygen contamination may be:

A� Addition of excessive make up water as a result of

leaks�

B� Absorption through open tanks and ttings.

C� Oxygen permeable materials in the distribution

system�

To insure long product life, oxygen sources must be

eliminated�

Take the following measures:

A� Repair system leaks�

B� Eliminate open tanks from the system�

C� Eliminate and/or repair ttings which allow oxygen

absorption�

D� Use non-permeable materials in the heating

system�

P/N 240009735, Rev. G [09/30/2016]

5 - LOCATING THE BOILER

Boiler shall not be installed on carpeting or vinyl

ooring.

Locate boiler in front of nal position before removing

crate�

Locate unit so vent pipe connection to chimney will be

short and direct�

When installed in utility room, door should be wide

enough to allow largest boiler part to enter, or to

permit replacement of another appliance such as water

heater

For basement installation, provide solid elevated base,

such as concrete, if oor is not level, or if water may be

encountered on oor around boiler.

Minimum clearances to combustible construction are:

TOP �� 24 IN�

FRONT �� 24 IN�

FLUE CONNECTOR �� 9 IN�

REAR �� 6 IN�

SIDES�� 6 IN�

Fresh air for combustion and ventilation must be

available at boiler� Ventilating and combustion air must

enter boiler room without restrictions�

Keep boiler area clear and free from combustible

materials, gasoline and other ammable vapors and

liquids�

DO NOT obstruct air openings to the boiler room�

WARNING

Fire hazard� Do not install on carpeting, or vinyl

ooring. Failure to follow these instructions could

result in death or serious injury�

NOTICE

Clearance for access should exceed re protection

clearance�

P/N 240009735, Rev. G [09/30/2016]

Boiler room ventilation must be adequate enough to

provide sufcient air to properly support combustion.

See Table 2�

When boiler is located in an unconned space in a

building of conventional construction frame, masonry

or metal, inltration normally is adequate to provide

air for combustion and ventilation� However, in any

building which has been altered to conserve energy

or to minimize inltration, boiler area should be

considered as a CONFINED SPACE� Provide combustion

air and ventilation air in accordance with the section

“Air for Combustion and Ventilation,” of NFPA 31:

Standard for the Installation of Oil-Burning Equipment�

* Unconned area: A space whose volume is not less than 50 cubic feet per 1000 Btu per hour of all

appliances installed in that space (cubic feet of space = height x width x length).

** Conned area: A space whose volume is less than 50 cubic feet per 1000 Btu per hour of all appliances

installed in that space (cubic feet of space = height x width x length).

When a boiler is installed in an unconned space,

in a building of unusually tight construction, air for

combustion and room ventilation must be obtained

from outdoors or from spaces freely communicating

with the outdoors� A permanent opening or openings

having a total free area of not less than 1 square

inch per 5,000 Btu per hour of total input rating of all

appliances shall be provided� Ducts may be used to

convey make-up air from the outdoors and shall have

the same cross-sectional area of the openings to which

they are connected�

6 - VENTILATION & COMBUSTION AIR

WARNING

Asphyxiation, re hazard. Do not obstruct air

openings to combustion area� Follow instructions

below, to maintain adequate combustion air�

P/N 240009735, Rev. G [09/30/2016]

When air for combustion and room ventilation is from

inside buildings, conned space shall be provided with

two permanent openings, one starting 12 inches from

the top and one 12 inches from the bottom of the

enclosed space� Each opening shall have a minimum

free area of 1 square inch per one thousand (1,000)

Btu per hour of the total input rating of all appliances

in the enclosed space, but must not be less than one

hundred (100) square inches� These openings must

freely communicate with the interior areas having

adequate inltration from the outside. See Figure #2�

When the boiler is installed in a conned space and

all air is provided from the outdoors, the conned

space shall be provided with two permanent openings,

one commencing within 12 inches from the top and

one commencing 12 inches from the bottom of the

enclosure� The openings shall communicate directly, or

by ducts, with the outdoors or spaces (crawl or attic)

that freely communicate with the outdoors� One of the

following methods must be used to provide adequate

air for ventilation and combustion�

A� When directly communicating with the outdoors,

each opening shall have a minimum free area of 1

square inch per 4,000 Btu per hour of total input

rating of all equipment in the enclosure� See Figure

#3�

6 - VENTILATION & COMBUSTION AIR

B� When communicating with the outdoors by means

of vertical ducts, each opening shall have a

minimum free area 1 square inch per 4,000 Btu per

hour of total input rating of all appliances in the

enclosed space� See Figure #4�

C� If horizontal ducts are used, each opening shall

have a minimum free area 1 square inch per 2,000

Btu per hour total input rating of all appliances in

the enclosed space� See Figure #5�

D� When ducts are used, they shall be of the same

cross sectional area as the free area of the area of

the openings to which they connect� The minimum

dimension of rectangular air ducts shall not be less

than 3 inches�

In calculating free area using louvers, grills or screens

for the above, consideration shall be given to their

blocking effect� Screens used shall not be smaller than

¼ inch mesh� If the free area through a design of

louver or grill is known, it should be used in calculating

the size opening required to provide the free area

specied. If the design and free area is not known, it

may be assumed that wood louvers will have 20-25%

free area and metal louvers and grills will have 60-75%

free area. Louvers and grills shall be xed in the open

position or interlocked with the boiler so that they are

opened automatically during boiler operation� Refer

to Combustion Air Requirements chart on page 7 for

combustion air minimum opening requirements�

Connect supply and return piping� See Figure #6� When

boiler is used in connection with refrigerated systems:

A� Chilled medium must be in parallel with boiler�

B� Use appropriate valves to prevent chilled medium

from entering heating boiler�

During heating cycle open valves A and B, close valves

C and D�

During cooling cycle open valves C and D, close valves

A and B�

A� Maintain minimum clearance of one inch to hot

water pipes�

In air handling units where they may be exposed to

refrigerated air circulation, boiler piping system MUST be

supplied with ow control valves or other automatic means

to prevent gravity circulation of boiler water during cooling

cycle�

Hot water boilers installed above radiation level must

be provided with low water device either as part of

boiler or at time of boiler installation�

When boiler is connected to heating system utilizing

multiple zoned circulators, each circulator must be

supplied with ow control valve to prevent gravity

circulation�

* Reduced pressure back ow preventer shall be used under

provisions required by the Environmental Protection Agency,

(EPA).

Bypass piping is an option which gives ability to

adjust supply boiler water temperature to t system

or condition of installation� Although, this method of

piping is not typically required for baseboard heating

systems�
