Specification

There’s no better built oil-fired boiler than Liberty. Every compo-

nent we use in the Liberty boiler is of the highest quality. Heat

exchanger sections, for example, are made of only the finest

cast iron, finished to exact specifications on automated high pre-

cision machining centers. Final assembly of each boiler is per-

formed by hand.

Multiple checks are made for quality and overall boiler integrity.

Every boiler section, for instance, is tested under pressure at

least 8 times the normal residential operating pressure.

Repetitive testing -- individual sections, assembled heat

exchanger and completed boiler -- ensure the leak-free integrity

of every boiler shipped.

Burner performance optimized for each specific

model. Ever

y burner factory tested.

The Liberty boiler is equipped with an advanced design Beckett

oil b

urner. The burner for each Liberty boiler is custom manufac-

tured to Slant/Fin specifications. It is engineered for each specif-

ic model to provide smooth, clean, efficient operation under all

job conditions. The flame is up to 200°F hotter and up to 35%

more efficient than older non-retention head burners.

For reliability, every burner is factory tested before shipping. It’s

given a full combustion test and fine tuned for optimal perform-

ance on the specific size boiler it is mounted on. Final adjust-

ments are easily made by the installer, if necessary, based on

the unique chimney draft conditions of each individual house.

For dependability, metal push nipples; name brand

contr

ols and circulator pump

Slant/Fin uses only metal push nipples that expand and contract

with the individual boiler sections that the

y connect. The rubber

gaskets that are substituted for push nipples in many other boil-

ers could deteriorate. This could result in water leaking from the

boiler and major repair bills.

Dependable performance is further ensured with nationally

known brands of controls and circulator pumps. All controls are

mounted and fully wired. Steam models include float type or

electronic low water cut-off.

Lifetime limited warranty. The Liberty boiler is engineered and built for a long, dependable life. Hot

water models are covered under Slant/Fin’s lifetime limited warranty. Steam models have a limited ten-year

warranty. Contact Slant/Fin for details.

LIBERTY II ® The world class oil-fired boiler In most boilers, the hot flue gases which rise from the combustion area must pass around the push nipples that join the heating sections. This results in uneven heat transfer, concentrations of soot buildup and undesirable draft loss. Liberty’s push nipples are located to the side, out of the way of the flue gases. This creates more uniform heat transfer, minimizes draft loss and reduces soot build-up. Boiler Model No. D.O.E.
