A. REMOVE CRATE — (Packaged Boilers)
1. Remove all fasteners at crate skid.
2. Lift outside container and remove all other inside
protective spacers and bracing. Remove draft
regulator box and miscellaneous trim bag
containing safety/relief valve, and pipe fittings.
B. REMOVAL OF BOILER FROM SKID
TS-39-26-A
1. Boiler is secured to base with 4 bolts, 2 on left side
and 2 on right side, see Figure 7. Remove all bolts.
2. Tilt boiler to right and to rear. Using right rear leg
as pivot, rotate boiler 90° in a clockwise direction,
and lower left side of boiler to floor. Tilt boiler and
remove crate skid. Care should be exercised to
prevent damage to jacket or burner.
C. MOVE BOILER TO PERMANENT POSITION by
sliding or walking.
D. INSPECT COMBUSTION TARGET WALL AND
COMBUSTION CHAMBER LINER
1. OPEN FLAME OBSERVATION DOOR AND/OR
BURNER SWING DOOR on front of boiler. Use
flashlight to inspect target wall secured to rear
section with silastic sealant. Inspect ceramic fiber
blanket secured to floor of boiler with water glass
adhesive. If either is damaged they must be
replaced.
E. CONNECT SUPPLY AND RETURN PIPING TO
HEATING SYSTEM.
CLEARANCES — Steam and hot water pipes shall
have clearances of at least ½" from all combustible
construction.
1. With STEAM HEATING, see Figure 8. Consult I =
B = R Installation and Piping Guide No. 200.
2. With Forced Circulation HOT WATER HEATING,
see Figure 9. Consult I = B = R Installation and
Piping Guide No. 200.
3. Packaged boilers. Install Safety Valve in Tapping
M. Use ¾ NPT x 8" nipple and ¾ NPT coupling
included in trim bag. Safety Valve must be
installed with spindle in vertical position.
SECTION III: INSTALLATION INSTRUCTIONS
Fig. 7
4. Packaged boilers with Probe style LWCO. Install
Limit in Tapping A using ¾ NPT x 2" nipple, ¾
NPT elbow, ¾ NPT x ¼ NPT bushing, and syphon
included in trim bag. See Figure on previous page.
Connect wiring harness from Low Water Cutoff.
See Figure below.
5. If this boiler is used in connection with
refrigeration systems, the boiler must be installed so
that the chilled medium is piped in parallel with the
heating boiler using appropriate valves to prevent
the chilled medium from entering the boiler, see
Figure 10. Also consult I = B = R Installation and
Piping Guides.
6. If this boiler is connected to heating coils located in
air handling units where they may be exposed to
refrigerated air, the boiler piping must be equipped
with flow control valves to prevent gravity
circulation of boiler water during the operation of
the cooling system.
7. Use a boiler bypass if the boiler is to be operated in
a system which has a large volume or excessive
radiation where low boiler water temperatures may
be encountered (i.e. converted gravity circulation
system, etc.).
Remove the circulator and install a pipe tee
between the circulator and boiler return along with
a second tee in the supply piping as shown in
Figure 11. The bypass should be the same size as
the supply and return lines with valves located in
the bypass and supply outlet as illustrated in Figure
11 in order to regulate water flow for maintenance
of higher boiler water temperature.
Set the by-pass and boiler supply valves to a half
throttle position to start. Operate boiler until the
system water temperature reaches its normal
operating range.
Adjust the valves to maintain 180°F boiler water
temperature. Adjust both valves simultaneously.
Closing the boiler supply valve and opening the by-
pass valve will raise the boiler water temperature
and lower the supply temperature. Opening the
boiler supply valve while closing the by-pass valve
will lower the boiler water temperature and raise
the supply temperature.
8. A hot water boiler installed above radiation level
must be provided with a low water cutoff device as
part of the installation.
