INSTALLATION OF VENT PIPE
When installing the SS2 Vent System on an oil appliance, a full size barometric draft control must be used. Install the barometric
draft control as shown, (See Diagram J). The SS2 inlet pipe is designed to accept 4" single wall, or Type "L" vent pipe. Type “B”
vent pipe is not acceptable for the SS2. The vent pipe used must be in compliance with local codes and the listing of the vent pipe
manufacturer. When necessary, install tapered reducers and increasers as shown below.
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 SS2 Vent System by adding the straight vent pipe length and the equivalent elbow lengths
together. Each 90 degree elbow is equal to 10 feet (3 meters) of straight vent pipe, each 45 degree elbow is equal to 5 feet (1.5
meters) of straight pipe. The equivalent vent pipe length must not exceed 50 feet (15 meters) from the appliance to the SS2 Vent
System. Vent runs of over 15 linear feet (4.5 meters) require the use of an approved, insulated vent connector to prevent prob-
lems related to condensation. It is not necessary to maintain 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).

INLET PIPE INSTALLATION
DIAGRAM H
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 SS2 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.
4. a) If installing the bracket into a wood wall, drill 2 pilot holes at each point established in step 3 with a 1/8" drill bit
approximately 1" deep and install the screws provided to secure the bracket to the wall.
b) If installing the bracket into a masonry wall, drill 2 holes at each point established in step 3 with a 1/4" masonry drill bit
Tap the masonry anchors into the 2 holes drilled and screw the wall bracket onto the wall.
NOTE “A”
Any vent pipe run that exceeds 15 linear
feet (4.5 meters) in length must use an
approved, insulated vent pipe. DO NOT
EXCEED 50 EQUIVALENT FEET (15
METERS).

IMPORTANT:
Adjust SS2 mounting
bracket for slight pitch.
