INTRODUCTION
1. Refer to burner manufacturer’s installation
manual provided for proper venting of the
gas train components that require atmospheric
pressure to balance a diaphragm.
2. All cover plates, enclosures and guards
must be in place at all times, except during
maintenance and service.
3. Insulate all steam and hot water piping, fittings
and connections and all other hot components
and equipment from personnel contact.
4. Assure all pipes, fittings, electrical controls and
all other associated burner/boiler equipment
is of proper design and construction for the
intended use and provides adequate protection
from electrical shock and harmful physical
contact to personnel.
5. A leak-tight fuel delivery conduit and control
system must be maintained at all times.
6. Products of combustion must be transported
from the boiler/burner system to the outdoors
in an approved, leak tight, insulated venting
system. The boiler room must be positively
ventilated to prevent a concentration of
products of combustion and a reduction in
the amount of oxygen in the air.
7. For optimum performance and serviceability
from this unit adhere to the following
recommendations:
A. Clean firetubes at least once a year,
preferably at the end of the heating season
to remove soot and scale. Inside surfaces of
the furnace, front and rear smokeboxes, and
reversing chamber should also be cleaned
at the same time.
B. Have the burner and controls checked at
least once a year or as necessary.
C. Retain your contractor or a competent
serviceman to assure that the unit is
properly adjusted and maintained.

psig steam boiler.
2. Heating surface for the 4FH.
3. Heating surface: “50” designates 5.0 sq ft

3. SETTING THE UNIT
Most boilers are equipped with lifting lugs to be
used in maneuvering the boiler into position. On large
boilers, where four lifting lugs are supplied, all four
lugs should be used when lifting the boiler.
A. Lifting and Rigging
Use of a spreader beam is preferred but not
mandatory. An approved, inspected, and rated
sling suitable for the total published boiler
weight shall be used. The correct WLL (working
load limit) shall be calculated based on the
sling angle used, and the WLL must not exceed
the sling rated capacity. The sling angle (angle
between the sling and the load) must not be
less than 60 deg. The boiler must be lifted as
level as practical (less than 5 degree tilt). Refer
to the boiler submittal drawing for dry boiler
weight.
