G) JACKET AND TRIM ASSEMBLY
1. Knock Down Boiler
a.
Jacket Assembly
- Unpack the jacket parts being careful not to damage the finish. Piping and
accessories are installed after the jacket is in place.
b.
Trim Assembly
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.
Install the limit control in the 3/4" fitting provided in the boiler plate.
Install the altitude/temperature gauge in the 1/4" fitting provided in the coil plate.
Install plugs provided in the parts box in all openings that are not used.
2. Packaged Boiler
Controls and burner are installed and prewired at the factory. Install Relief Valve as noted in
Figures 6 and 7.
H) BOILER PIPING
This style of boiler is equipped with a built in “Air Scoop
System.” This feature allows quiet air free operation of your
hot water system by assuring the removal of noisy air pock-
ets. 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. All plugs and water connec-
tions should be checked for leaks upon installation and annual-
ly.
WARNING:
Relief valve discharges and drain valve piping must be piped to a safe place
of discharge.
I) TANKLESS WATER HEATING PIPING
The tankless heater may be connected as shown in Figure 6. High temperature water for a dish-
washer may be obtained by piping as shown.
The nuts that secure the tankless coil flange should be tightened before the boiler is filled with
water, after initial firing and every year during annual maintenance. Deterioration due to coil gas-
ket leaks shall void warranty.
WARNING:
An anti-scald/mixing valve (not supplied) must be used to reduce the water
temperature at kitchen or bathroom taps.
