quickly and efficiently while

providing unmatched durability.

The pinned

heating surface

and vertical

flue design

extracts

maximum heat

while

maintaining

low draft

losses. This results in higher

efficiencies and lower fuel costs.

The Cast Iron Nipple Difference

Burnham Commercial's Series 8B

boiler sections are joined with

quality cast

iron nipples

that last the life

of the boiler.

They expand

and contract

along with the

Adaptable to Any Job

The Burnham® Commercial

Series 8B boiler provides

outstanding single and multiple

boiler performance and reliability.

The boiler can be arranged for

space heating or combination space

heating and domestic hot water

heating with the use of an

Alliance™ indirect-fired water

heater. The compact design and one

inch minimum side clearance make

the Series 8B ideal for modular and

multiple boiler installations*. Large

homes, multi-family dwellings,

small businesses and office

complexes are typical applications

for the Series 8B boiler.

Cast Iron Dependability

The Series 8B boiler is

constructed with durable cast iron

sections. Cast iron has the unique

ability to absorb and transfer heat

SERIES 8B COMMERCIAL ATMOSPHERIC

GAS-FIRED HOT WATER BOILER

sections they join ensuring the

integrity of the entire section

assembly. Cast iron nipples resist

petroleum based chemicals,

including corrosion inhibitors,

pump lubricants, and antifreeze,

and they do not break down from

contact with boiler flue gases, all

of which can deteriorate the

gaskets commonly used in some

competitors’ boiler assemblies.

Features Beyond the Standard

A flame roll-out switch and

blocked vent switch are standard

equipment on all Series 8B boilers.

The flame roll-out switch senses

temperature in the vestibule and

the blocked vent switch senses

temperature at the flue outlet.

The switches will safely shut

down the boiler in the event the

boiler, chimney or venting system

becomes blocked or restricted.

*Minimum recommended side-to-

side clearance for modular/multiple

boiler applications is one inch or as

required by local authorities. New EP

and OP electronic control sets are

designed to mount on top of the

boiler and does not affect side

clearances. When equipped with IRI

(Industrial Risk Insurers) controls,

the gas train will mount along the

right side of the boiler, requiring 18”

service clearance.

*Please refer to the Modular/Multiple

Boiler and Controls literature and

Modular manual for detailed

installation information.

Modular or Multiple

ASME Section IV differentiates

between modular and multiple

boiler installation. According to

ASME, a modular boiler system

consists of individual modules with

a maximum input of 400 MBH

each. Each module is to be

equipped with a pressure

temperature gauge, temperature

limit control, safety relief valve and

drain valve. The modules are to be

manifolded together on site without

any intervening stop valve. The

modular boiler assembly is to be

equipped with a common

temperature limit control, low water

cutoff, makeup water connection,

provision for thermal expansion and

supply and return stop valves.

Multiple boiler installations

require a stop valve in the supply

and return pipe connection of each

boiler. Each boiler needs to be

equipped with a pressure

temperature gauge, two

temperature limit controls, safety

relief valve, and drain valve.

Boilers over 400 MBH must also

include an automatic low water

cutoff. Sizes 805, 6 and 7 can be

installed as modular or multiple

boilers. Sizes 808, 9 and 10 are to

be installed as multiple boilers. In

both cases, minimum recommended

side-to-side clearance is one inch or

as required by local codes.

Commitment to Quality
