NOTE “A”
Any vent pipe run that exceeds 15 linear
feet in length must use an approved,
insulated vent pipe. DO NOT EXCEED
50 EQUIVALENT FEET.
Typical short vent pipe installation
ELECTRICAL WIRING
All wiring from the SS2G to the appliance must be appropriate Class 1 wiring as follows: installed in rigid metal conduit, intermediate
metal conduit, rigid non-metallic conduit, electrical metallic tubing, Type MI Cable, Type MC Cable, or be otherwise suitably
protected from physical damage.
Note: We recommend the use of flexible conduit for connections to the SS2G to allow for slide
out servicing feature of venter assembly.
The electrical contact ratings for the diaphragm Fan Proving Switch and High Limit are as follows:
FAN PROVING SWITCH HIGH LIMIT
3 Amps (full load) at 24 VAC 10 Amps (full load) at 24 VAC
36 Amps (locked rotor) at 24 VAC 60 Amps (locked rotor) at 24 VAC
The Fan Proving Switch and High Limit are not suitable for loads which exceed the above limits.
1. The installer must ensure that all electrical connections between the appliance and Power Venter are tight and that all wires are
positioned and secured so they cannot come in contact with high temperature locations. Use adequate conduit supports where
necessary.
2. The installer must ensure that the internal appliance transformer is rated no lower than 40VA.

INLET PIPE INSTALLATION
1. Remove 4” round inlet pipe from box.
2. Align the 4 slots of the inlet pipe to the 3 pins and
proving switch sensing tube, push pipe up until it
bottoms out in the SS2G inlet.
3. Turn the inlet collar clockwise to lock in place,
(See Diagram I). IMPORTANT: After vent pipe
is installed verify inlet pipe is locked tightly in place.
INSTALLATION OF VENT PIPE
The SS2G inlet is designed to accept 4” single wall or type “B” vent pipe. It will also accept 4” flexible vent connectors. The vent
pipe used must be in compliance with local codes and the listing of the vent pipe/connector manufacturer.
Always use a vent pipe/connector of the same diameter as the appliance flue outlet. Use a tapered reducer near the SS2G inlet
pipe if the appliance flue outlet is larger than 4”.
Determine vent pipe layout which will allow for the least amount of elbows to the appliance. Calculate the equivalent vent pipe
length from the appliance to the SS2G Vent System by adding the straight vent pipe length and the equivalent elbow lengths.
Each 90 degree elbow is equal to 10 feet of straight vent pipe, each 45 degree elbow is equal to 5 feet of straight pipe. The equiv-
alent vent pipe length must not exceed 50 feet from the appliance to the SS2G Vent System. Vent runs of over 15 linear feet
require the use of an approved, insulated vent connector to prevent problems related to condensation. It is not necessary to main-
tain a 1/4" rise per foot of horizontal when Side Wall Venting.
NOTE: Installing a vent pipe “jog” on vertical vent pipe layouts allows for easier dismantling when servicing is necessary,
(See Diagram J).
