SWG
Power Venter
Gas and oil heating appliances generate heat through
the combustion of fuel. The heat is transferred through
the heat exchanger and distributed to the conditioned
space. The products of combustion, however, must be
vented safely out of the structure. In a conventional
chimney, venting is achieved by the natural lifting action
of the hot combustion gas. New, efficient systems absorb
more of the heat in the heat exchanger and produce
lower temperature vent gas. Lower temperature gas
does not rise as quickly or as reliably as in older, less
efficient systems. Power venting or sidewall venting is
more economical and safer than chimney venting. A
power venter uses a motorized blower to vent the
products of combustion. A power venter is interlocked
with the appliance to ensure that proper draft is
achieved before the appliance burner is activated.
The SWG Power Venter is the safest, most
efficient power venter available today.
Patented SWG Power Venters are ETL and cETL listed
for all LP gas, natural gas, or oil-fired heating
equipment. The SWG combines the motor, blower,
and vent hood in one complete, easy to install unit.
The SWG mounts on the outside of the building and
pulls the combustion gases from the appliance
through the outside wall utilizing 100% negative
pressure.
Benefits of the SWG Power Venter include:
• 100% negative pressure in the vent pipe for
maximum safety.
• Standard galvanized pipe can be used instead of
expensive stainless steel.
• No need to seal vent pipe joints, saving time and
money.
• Significantly longer vent lengths than positive
pressure, direct vent systems.
• The SWG is recommended by major heating
appliance manufacturers.
The SWG must be sized to match the appliance or
appliances input firing rate. Most firing rates are
published in the manufacturer’s installation manual.
SWGs must be installed with a CK Control Kit to
ensure proper listing and safe, efficient venting.
How the SWG Works
When to use the SWG:
• Use with gas or oil furnaces, boilers, and water heaters.
• New construction.
• When converting from electric to gas or oil.
• To avoid relining a chimney.
• When installing an additional heating appliance.
• When co-venting a water heater with a furnace.
1. The thermostat calls for heat, energizing the
Power Venter (A).
2. A negative pressure is created, closing the
pressure switch on the control kit (B).
3. The burner (C) is activated and combustion gases
are exhausted (D).
4. After the thermostat is satisfied, the burner shuts
down and the venter continues to post purge,
exhausting residual flue gases.
5. When the timer or temperature control is satisfied,
the venter is deactivated.
