VI. PLACING THE BOILER
The boiler should be placed to provide the most
direct connections to the combustion air, vent and
system piping as possible.
Place crated boiler as close to selected location
as possible and uncrate boiler. The uncrated boiler
may be moved into position with an appliance dol-
ly or 2-wheel hand truck. The dolly or hand truck
should be inserted under the
right hand side
of
the boiler. It is possible to slide the boiler for a short
distance on a smooth floor or surface.
NOTE:
Refer to
“Locating The Boiler”
in Section V for re-
quired clearances for servicing and maintenance.
VII. NEAR BOILER PIPING
Determine required system fill pressure, system de-
sign temperature, and system water content. Boiler
contains 2.6 gallons (U.S.). Size expansion tank ac-
cordingly. Consult expansion tank manufacturer for
proper sizing information. Connect properly sized
expansion tank (not furnished) as shown in Figure 6
for diaphragm type expansion tank. For diaphragm
type expansion tanks, adjust the tank air pressure
to match the system fill pressure. Install air vent
(furnished) as shown for diaphragm type expansion
tank system only. Install make-up water connec-
tions as shown and per local codes. If a pressure
reducing valve is used, adjust to match the system
fill pressure. In connecting the cold make-up water
supply to the boiler, make sure that clean water sup-
ply is available. When the water supply is from a well
or pump, a sand strainer should be installed at the
pump.
PRESSURE RELIEF VALVE /
TEMPERATURE PRESSURE GAUGE
The boiler is furnished with a relief valve and tem-
perature pressure gauge in the boiler parts bag. In-
stall vent relief valve as shown in Figure 7. Provide
¾” piping from the relief valve to a local floor drain,
!
!
CAUTION
Copper supply and return piping must NOT be in-
stalled directly into aluminum boiler section castings
due to galvanic corrosion between dissimilar met-
als. Iron or steel bushings or pipe nipples should
be used between copper system piping and boiler
to make final connection to boiler. Also, the use of
dielectric unions is acceptable. The packaged boiler
is furnished with iron piping in the front boiler sec-
tion for the supply and return connections.
When the installation of the boiler is for a new heat-
ing system, first install all of the radiation units (pan-
els, radiators, baseboard, or tubing) and the supply
and return mains. After all heating system piping and
components have been installed, make final con-
nection of the system piping to the boiler.
A hot water boiler installed above radiation level must
be equipped with a low water cut off device (included
with boiler). A periodic inspection is necessary, as is
flushing of float type devices, per low water cut off
manufacturers specific instructions.
