GOLD CGa Gas-Fired Water Boiler — Boiler Manual

Part Number 550-101-009/0107
Prepare boiler — draft hood & spill switch
Draft hood installation
1. Orient draft hood with spill switch mounting holes to front of boiler
as shown in Figure .
. Secure draft hood to outlet at top of boiler with sheet metal screws.
3. Bottom of draft hood or “skirt” must have clearance dimension above
jacket top panel as indicated on draft hood.
Do not alter boiler draft hood or place any obstruction or
non-approved vent damper in breeching or vent system.
CSA certification will become void. Flue gas spillage and
carbon monoxide emissions will occur causing severe
personal injury or death.
Spill switch installation
1. Fasten spill switch to draft hood as shown in Figure 6
and Figure 7 .
. See Wiring diagram to connect wires:
a. Standing pilot boiler — see page 34 .
b. Spark-ignited pilot boiler —
see pages 38 and 39 .
Improper orientation of spill switch
may cause boiler to shut down. The
loss of heat can result in significant
damage due to freezing.
Prepare boiler — install vent piping
1. Connect from draft hood or vent damper outlet to chimney or vent
with same size vent connector.
. Where possible, vertical venting to the outside from the draft hood or
vent damper outlet will offer best performance.
3. Where horizontal vent connector is used, slope upward at least ¼” per
lineal foot toward chimney or vent and support with hangers to prevent
sagging.
4. Breeching must not be connected to any portion of a mechanical draft
system that can operate under positive pressure.

Long horizontal vent connector,
excessive number of elbow or
tees, or other obstructions that
restrict the flow of combustion
gases should be avoided. Severe
personal injury, death or sub-
stantial property damage could
result.
