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.
 

SWG SPECIFICATIONS CHART

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.
 

UNIT SIZING CHART

* Oil: Select venter according to the actual rated maximum GPH input. SWG GPH ratings at 100 psi. Do not exceed maximum oil GPH input. ** Gas: Do not exceed maximum BTU/HR input rating. For multiple venting system applications add the input for each appliance. Category III gas-fired draft induced systems require an SWG-5 or larger.

Unit sizing may vary depending on specific application. Consult your dealer or factory representative for the proper sizing for your particular application.

80+ gas-fired draft induced systems require an SWGII-4HD or larger.
