Cast Iron Commercial Water or Steam Boiler

Your Commercial Heating Solution!
Available in twenty sizes with gross output ratings from
667	to	4551	MBH,	the	V11	Series	is	commonly	used	in	
schools, hospitals, and other large commercial applications
where comfort and reliability are critical. The product meets
the	energy	efficiency	requirements	of	ASHRAE	90.1	with	
combustion efficiencies up to 85%.

Installation & Service Flexibility

Cast iron construction, ease of assembly, two venting options,
and	stringent	testing	methods	make	the	V11	Series	boiler	by	
Burnham Commercial your commercial heating solution.

• Hassle-free Section Assembly

The	cast	iron	sectional	design	of	the	V11	boiler	makes	it	easy	to	
maneuver through doorways and into the boiler room. In addition to being shipped as loose sections, the boiler is available
with factory-assembled sections or as a completely packaged
and fire-tested unit.
V11	boiler	sections	have	reinforced	lugs	that	are	used		
to assemble the sections with individual draw rods
resulting in fast, strain-free assembly.

American-Made Cast Iron ConstructionÐ
BC25-HSi

Burnham CommercialÕ s unique
BC25-HSi	cast	iron	formula	has	
an extremely high silicon content,
making it stronger and more
flexible than the iron used in
competitor's boiler sections. It offers
better thermal shock resistance and
greater heat transfer capabilities
than other cast iron products.
BC25-HSi's	properties	allow	Burnham	Commercial	to	
maintain the highest level of quality from start to finish, and
provide a product that is optimized
for hydronic heating applications.

The sections can be assembled using two common
toolsÑ a 3/4" drive ratchet with a 1-1/16" deep socket
and wrench. The sections are surface ground to ensure
smooth surface mating. An elastic sealant and fiberglass
rope are used on all section joints for a completely sealed
and pressure-tight assembly.

• extensive Testing Methods

Each boiler section is hydrostatically tested at 2-1/2 times
	 the	rated	working	pressure	at	the	foundry.	Factory-		
	
assembled sections are tested a second time at 1.5 times the
rated working pressure.

• Manufactured with Quality
Cast iron sections are produced at
	 Burnham	Foundry	LLC	in	Ohio,		 	
ensuring quality and availability of
boiler sections.

• Rear or Top Venting

As	a	forced	draft	boiler,	the	V11
provides optimum draft for controlled
efficiency, eliminating the need for
high chimneys or induced draft fans.
	 A	unique	feature	of	the	V11	boiler
is that it can be vented from the
rear or the top. This enables easy
chimney or sidewall venting for
maximum installation flexibility.
Top outlet venting saves floor space
and reduces installation time and
materials. A plugged tapping is
provided to take flue outlet pressure
readings.

• Cast Iron nipple Difference
V11	sections	are	held	together
using cast iron nipples, which
are well known as being of the
highest standard for boiler
construction. Unlike gaskets used
by many other boiler
manufacturers, cast iron nipples are impervious to flue
gases, oils, petroleum-based chemicals and other
contaminants, which means fewer costly repairs and a
longer lasting boiler.

1.	 All	piping	is	schedule	40.
2. To prevent condensate from being trapped in header, do not reduce
equalizer elbow at header connection.
3.	 Drain/blowoff	valve	—	ball	valve	preferable,	gate	valve	acceptable		
alternative (supplied by others).
	 -	Minimum	valve	size	per	ASME	code	is	1"	NPT	(V1104-1106),	1-1/4"		
	 	 NPT	(V1107-1112),	1-1/2"	NPT	(V1113-1123).
- Increasing the valve size will improve the blowdown operation
- In all cases, piping connecting blowoff valve to boiler shall be full
size to the point of discharge.
4.	 Header	piping	may	be	run	over	the	top	of	boiler	if	space	does	not	
allow for piping arrangement shown.
	 However,	increased	service	requirements	will	result.
5. Supply from boiler header must be connected between the first boiler
	 riser	and	the	header	drip	(or	hartford	loop).	Do	not	connect	supply		
between risers or opposite end of boiler header.

gas/oil fired.
2.	 Boiler	ratings	are	based	on	13%	CO2	on	oil;	10.0%	CO2	on	gas,	and	+	.10	in.	water	column	pressure	at	boiler	flue	outlet.
3.	 I=B=R	net	ratings	shown	are	based	on	piping	and	pick	up	allowances	which	vary	from	1.333	to	1.288	for	steam	and	1.15	for	water.	Consult	
manufacturer for installations having unusual piping and pick up requirements, such as intermittent system operation, extensive piping systems, etc.
4.	 The	I=B=R	burner	capacity	in	GPH	is	based	on	oil	having	a	heat	value	of	140,000	BTU	per	gallon.
Ratings	shown	above	apply	to	altitudes	up	to	1000	feet	for	oil	and	2000	feet	for	gas.	For	altitudes	above	those	indicated,	the	ratings	should	be	reduced	
at	the	rate	of	4%	for	each	1000	feet	above	sea	level.
