3.
Assemble Gas Cushion Chamber (GCC) to the
Combustion Chamber Inlet. Replace the GCC
gasket. Locate clamp ring and secure with 1/4"
washers and nuts.
4.
Attach the gas supply tube from the GCC to the gas
pipe in the ACC.
5.
Reconnect the pressure sensing tube on the GCC.
6.
Reattach the ignition lead to the spark plug.
7.
Replace lid on the ACC. NOTE: If the air inlet piping
was disconnected at the ACC skip this step.
8.
Replace and secure the hi-limit bulb making sure it
is bottomed in the well. Carefully route the
capillary tube to avoid contact with sharp edges.
Place excess capillary tubing flat on the top rear head
of the boiler.
9.
Replace the insulation on the top head of the boiler
(front and rear). Replace the jacket.
a.
Mount the side panel bracket on the support
rails at the bottom of the economizer. Align
the opening in the left side panel with the gas
valve.
b.
Attach rear bottom, rear top and front bottom
panels.
c.
Before attaching the front upper panel connect
the two black leads with quick connects to the
Rocker Switch. Screw the front panel in place.
Re-connect the red light leads (one brown and
one white) and the green light leads (one
orange, one white).
REPOSITION BOILER IN ITS LOCATION [AM-300]
1.
If the venting was cut when the boiler was removed,
reconnect the cut sections with couplings. Cement
venting joints.
2.
If the venting was disconnected from the boiler:
a.
Use the new flue box gasket and follow
directions supplied to reattach the flue box.
b.
To reconnect the air inlet adapter, clean the old
silicone from the ACC's inlet adapter. Apply a
thin bead (approximately 3/16" wide) of silicone
caulk completely around shoulder of the
adapter. Insert the adapter through the opening
in the ACC. Screw the locknut onto adapter, and
tighten securely.
(1) Reinstall rear wall and right side wall
insulation in the ACC (press to fit in place).
(2) Remove the gasket from the blower inlet
and attach a new gasket without stretching it.
Align the gasket with the edge of the blower
inlet. Trim the excess and butt the ends to form
a complete circle. Connection must be
leak-tight.
(3) Replace spacers on the blower assembly
mounting studs.
(4) Check compression marks on old gasket. If
the compression marks on the old gasket were
not complete and concentric around the inlet,
bend the studs as required to obtain proper
alignment between the inlet and adapter. If
there is a gap between the face of the gasket
and adapter, remove spacers from the studs
and shorten the spacers 1/16" more than the
aforementioned gap.
(5) Remount blower assembly on mounting
studs. Reinstall blower assembly nuts and
tighten securely. Reconnect power leads.
(6) Replace lid on ACC and tighten nuts
securely.
