A. SETTING THE BOILER
1. Provide a level foundation, located as close as
possible to the center of the heating system.
2. Refer to Figure 2.2 for exploded view of boiler while
checking and/or assembling parts of the boiler.
3. See clearance information in Section 1,
"Preinstallation."
4. On packaged boilers, open burner mounting plate
(Item 3) at this time to make certain the target wall
(Item 2) is seated in the back of the combustion
chamber. Ceramic fiber blanket base liner (Item 28)
should be lying flat on bottom of combustion
chamber between target wall and burner.
B. OBSERVATION COVER ASSEMBLY
(KNOCKDOWN BOILERS)
1. Remove observation door (Item 4) from inside
burner mounting plate. Attach the observation door
to the outside of the mounting plate.
C. INSTALLATION OF FLUE COLLECTOR &
COVERPLATES (KNOCKDOWN BOILERS)
1. Open flue collector carton. Remove flue collector
(Item 9) and high temperature rope. Lay rope (Item
8) on top of boiler against bead provided. Place flue
collector on top of rope and attach to boiler with
1/4"-20 x 1-3/4" studs with nuts through flue
collector brackets into the tapped lugs provided in
the top of the boiler end sections. Draw nuts down
snugly.
2. Remove clean-out cover plates and insulation (Item
25). Each clean-out cover plate is attached to the
boiler by using two carriage bolts, nuts and washers
(Item 24). Install the carriage bolts into the notch at
the top and bottom of each clean-out opening, then
secure them with a flat washer and steel nut as
shown in Figure 2.1 locking them in place. Press the
clean-out plate with insulation over the protruding
carriage bolts until the bolts punch through the
insulation so flat washer and brass nut can be
installed. Tighten down nuts snugly compressing the
insulation to form a good seal around the clean-out
opening.
D. TANKLESS HEATER OR COVERPLATE
If an ECT steam boiler is to be installed with a tankless
heater coil, the coil must be installed before the left side
jacket panels are attached. When a tankless heater is
not employed, cover the heater opening with cover plate
(Item 12 or 16).
See Section 3, Piping and Controls, for piping
information.
E. JACKET ASSEMBLY
1. Refer to Figure 2.2 for exploded view.
2. Attach the back panel (Item 19) to bosses on middle
of back section with two 1/4" x 3/8" truss head
machine screws (Item 20) provided. The back panel
has two 5/16" diameter holes close to the center of
the panel.
3. Lift off the burner mounting plate.
4. Remove the (2) knock-outs in the front jacket panel
(Item 23) which allow clearance for the hinge. Place
the front jacket panel on the block and replace the
burner mounting plate.
5. Attach right side jacket panel (Item 22) to the front
and back panels with sheet metal screws.
6. On steam boilers, if a tankless heater is used, remove
the knock out in upper left side jacket panel (Item
21) and back jacket panel (Item 19) before installing.
Attach left side jacket panels in the same manner as
the right side panel.
7. Attach the top panel (Item 26). Secure top panel to
