Gas-Fired Direct Vent Cast Iron Boilers – Field Assembly Instructions

Step 1
Place runner beams on base (see BLOCK ASSEMBLY SEQUENCE NO-
TICE on page 2 — assembly can be from back to front if necessary)
Make sure the boiler base is in the correct position before
starting. The legs extend longer on the FRONT end of the base
than on the rear end (approximately 9-1/2 inch at front and 6-3/4
inch at rear — use a tape measure if necessary to compare).

LOCATE BOILER TO
PROVIDE MINIMUM
CLEARANCES FOR
ASSEMBLY AND AS
REQUIRED BY KN BOILER
MANUAL:
Th e boiler must be installed
in accordance with the KN
Instruction Manual — the
boiler location must maintain
all required clearances for
service and spacing from
combustible surfaces.
In addition, provide:
AT LEAST 60 INCHES
clearance at the
front
of
the boiler to allow room for
block and condensate pan
assembly.
1. Remove base from skid.
2. The base is symmetrical, so either end
can be placed as the front end.
3. Place a beam (supplied) against each
side as a runner as shown at right.
4. The planed surface of the beam must
be on top.
5. If beam has any curvature, place the
beam with the curvature toward the
OUTSIDE of the frame.
6. Space runner beams with about even
lengths extending off of each end of
the base.
7. The runner beams will be used to
support the boiler block during
assembly, then removed afterward.
Step 2
Oil top surface of runner beams
DO NOT allow oil to drip
on the fl oor
.
Make sure the fl oor is free
of any slick spots and that
there is no debris or any
obstruction in the work area
or walk path to boiler parts.
1. Use a paint brush to spread 30-wt
motor oil on the runner boards. This
allows sections to move easily during
draw-up.
Step 3
When lifting the sections
Use leather gloves when
lift ing or moving boiler
sections. Sections are heavy
and can cause severe personal
injury or death if mishandled.
Lift section using two
people. Then place in
position on the runner
beams. Make sure
the section is always
supported to prevent
tipping or falling.
1. Lift section with each person lifting at
the bottom of the section.
2. Move onto the runners and slide into
position.
3. Handlers should lift with their legs to
avoid back strain.
