A Message to: Installer, Serviceman, Homeowner:
Over seventy five years of engineering and product development have gone into your new Columbia
oil fired boiler. It's quality and design are unsurpassed. Properly installed and maintained, it will provide
many years of efficient and dependable operation. Please read this Instruction Manual carefully. The infor-
mation contained within is designed to help you maintain peak performance from your boiler/burner unit.
A. Installation Instructions
CAUTION:
1. Installer must be a trained, experienced serviceman.
2. Inspect the boiler, jacket and all components to be sure damage has not occurred in shipment. If
damage is evident you must file a claim with the freight carrier immediately.
3. Disconnect power supply before connecting wiring.
4. Refer to local installation codes for oil burning equipment, for recommended installation practice.
5. A complete heat loss calculation is necessary to choose the proper size unit to install. The boiler
should be sized to within 25% of the actual heat loss of the structure.
6. Conduct thorough checkout when installation is complete.
1) Place the boiler on a level non-combustible
floor, preferably raised and as close to the
chimney as possible. The following minimum
clearances must be adhered to during instal-
lation and maintained thereafter to properly
clean, inspect and service your boiler: sides
and back - 6"; front - 24" and vent connector
- 18". Reduced clearance installations must
follow NFPA-31 guidelines.
2) For location of piping refer to the installation
drawing in Figure 1. The burner, aquastat
and circulator are wired at the factory. For
power and thermostat (not supplied) wiring
connections see the control manuals provid-
ed along with this manual. For piping and
wiring of other system components see the
manufacturers installation manuals.
3) The tankless water heater may be piped as
shown in Figure 1. A mixing valve, not sup-
plied, must be used to reduce the water
temperature at kitchen or bathroom taps.
High temperature water for a dishwasher
may be obtained by piping as shown in

Emerald Series Installation and Operators Manual
Figure 1. The nuts that secure the tankless
coil flange should be tightened before the
boiler is filled with water, after initial firing
and once a year during the annual mainte-
nance. DETERIORATION DUE TO COIL
GASKET LEAKS WILL VOID THE WARRAN-
TY.
3a) This style of boiler is equipped with a built in
"Air Scoop System." This feature allows
quiet air free operation of your hot water sys-
tem by assuring the removal of air pockets
without the installation of Air Scoops to trap
noisy air.
The 1-1/4" 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 sup-
ply 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.
