SWG Power Venter - Side Wall - Field Controls

What is Power Venting? The SWG Power Venter is
the safest, most efficient power venter available today.
SWG Power Venters are all ETL and cETL listed for any 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 gas 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. SWG’s must be installed with a CK Control Kit to
ensure proper listing and safe, efficient venting.
The standard SWG Power Venter is designed for walls up to 8" thick. PEK extension kits allow the SWG to
be installed in walls up to 16" thick. The PEK kit includes the inner/outer pipe extension, air flow
damper and one foot of 1/4" aluminum tubing. It is available for models SWG-4 through SWG-8.
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 safe 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.

SIZING THE VENTER - USE MAXIMUM BTU OR GPH INPUT
Size the SWG venter based on the input firing rate of the appliance. If the power venter is being used
to vent multiple appliances, add the input firing rates for each appliance and use that total to size
the venter. Knowing the total input BTU/HR for gas or GPH for oil, the venter can be sized from table
1. Select the venter rated closest to the total input BTU or GPH for installation. If the input of the
appliance is higher than the max allowable for that size SWG, move to the next larger size SWG. Do not
select a venter with a maximum BTU/HR or GPH lower than the appliance. The equivalent feet of vent pipe
for the installation must be calculated (See Page 14). Based on the vent pipe diameter to be used,
compare the calculated equivalent feet of vent pipe with the maximum equivalent feet allowable for the
venter (See Table 1). If the calculated equivalent feet is greater than that allowed for the venter,
increase the diameter of the vent pipe to be used and refer to the table or use the next larger size
SWG venter.
Sizing The Venter
Size the SWG or ComboVent venter based on the input firing rate of the appliance. If
the power venter is being used to vent multiple appliances, add the input firing rates for each
appliance and use that total to size the venter. Knowing the total input BTU/hr. for gas, or GPH for
oil, the venter can be sized from Table 1. Select the venter rated closest to the total input BTU or
GPH for installation. If the input of the appliance is higher than the maximum allowable for that size
SWG or CV, move to the next larger size SWG or CV.
Do not select a venter with a maximum BTU/hr. or GPH lower than the appliance. The equivalent feet of
vent pipe for the installation must be calculated. Based on the vent pipe diameter to be used, compare
the calculated equivalent feet of vent pipe with the maximum equivalent feet allowable for the venter
(See Table 1). If the calculated equivalent feet is greater than that allowed for the venter, increase
the diameter of the vent pipe to be used and refer to the table or use the next larger size SWG or CV
venter.
Note: In Table 1, the maximum equivalent footage allowable for the vent pipe is given for two
points, the maximum BTU/hr. venting capacity and at 60% of the maximum. This allows for estimating
values between the two given points.

The maximum equivalent footage allowable for the
vent pipe is given for two points, the maximum BTU/HR venting capacity and at 60% of the maximum.
This allows for estimating values between the two given points.
Size the SWG venter based on
the input firing rate of the appliance. If the power venter is being used to vent multiple
appliances, add the input firing rates for each appliance and use that total to size the venter.
Knowing the total input BTU/HR for gas or GPH for oil, the venter can be sized from table 1.
Select the venter rated closest to the total input BTU or GPH for installation. If the input of
the appliance is higher than the max allowable for that size SWG, move to the next larger size
SWG. Do not select a venter with a maximum BTU/HR or GPH lower than the appliance. The equivalent
feet of vent pipe for the installation must be calculated (See Page 14). Based on the vent pipe
diameter to be used, compare the calculated equivalent feet of vent pipe with the maximum
equivalent feet allowable for the venter (See Table 1). If the calculated equivalent feet is
greater than that allowed for the venter, increase the diameter of the vent pipe to be used and
refer to the table or use the next larger size SWG venter.
