VII JACKET AND TRIM ASSEMBLY
A. Knock Down Boiler
1. Jacket Assembly - Unpack the jacket parts being careful not to damage the finish. Piping and acces-
sories are installed after the jacket is in place. Assemble the jacket as shown in Figure 5.
2.
Trim Assembly
a. Install the safety relief valve in the 3/4" tapping in the top of the boiler. The relief valve should be
piped to a safe place of discharge.
b. Install the limit control in the 3/4" fitting provided in the tankless coil plate.
c. Install the altitude/temperature gauge in the 1/4" fitting provided in the coil plate.
B. Packaged Boiler
Controls and burner are installed and prewired at the factory. Install Relief Valve as noted in Section 2a
(Trim Assembly).
VIII BOILER PIPING
This style of boiler is equipped with a built in “Air Scoop System -
Figure 2.” This feature allows quiet air free operation of your hot water
system by assuring the removal of noisy air pockets. The supply line
or Riser tapping in the top of the boiler extends approximately 1"
below the top or waterline of the boiler, thus allowing only air free
water to enter the supply to the heating system. The air trapped in
the top of the boiler is then purged through a 3/4" vent tapping to be
released with an (1) automatic float vent (2) a manual vent or (3)
piped into a conventional type expansion tank.
Relief valve discharges and drain valve piping should be piped to a safe
place of discharge. All plugs and water connections should be checked
for leaks upon installation and annually.
