Joint Sealing and Connection Method
Polyflue rigid single wall pipe is manufactured with a factory installed gasket on the inside of the female (outlet)
end making the use of any additional sealant unnecessary. Flexible pipe (female end) will require to field apply a
gasket as shown in the flexible section. Locking Bands (LB) are required on all connections, except as noted
elsewhere in this document.
Connection
Note: Apply a mild soap/water mix to the gasket by spray bottle, brush or dipping the gasket pipe end into a
bucket to aid in joint connection. Do not use any petroleum based lubricant on gasket.
1. Slide the Pipe Locking Band (LB) onto the male end of the downstream connecting pipe (Fig 1).
2. Push the pipes together using a slight twisting motion until the male end bottoms out. Then retract the
joint approximately 1/8” (3mm) – 1/4” (6mm) to compensate for thermal expansion.
3. Slide Locking Band over the female end of the connection and tighten up both hose clamps (Fig 2).
4. See Figures 3 & 4 showing connections to elbows & tees.
Pitch and Flue Gas Condensate Removal
Polyflue, installed horizontally, must have an
upward
pitch at a minimum 3/8” rise per foot (31mm / 1000mm) so
that condensate can drain back toward the appliance or inline drain section. If an internal condensate drain is
NOT part of the appliance:
A Polyflue Vertical/Horizontal In-Line Drain Section (CD) or Tee (with branch pointed down and Drain Cap
(TCD) attached) is required. Install this drain fitting as close to the appliance flue outlet as possible (Tee
method is only good for horizontal pipe).
A Condensate Drain Tube Kit (CDT) is available to drain the condensate to an appropriate location (i.e.
floor drain or vented sanitary sewer connection). A trap loop must be formed into the drain hose and
must be a diameter that is at least four times the appliance's rated stack pressure in inches of water
column or 3 inches (76mm), whichever is greater. Secure the loop with a cable tie. Prior to final assembly
the trap loop must be 'primed' by pouring a small quantity of water into the drain hose.
Follow all local and national codes and regulations for the draining of acidic condensate.
In cold climates do not install a condensate drain on the exterior of the building. Doing so may result in
dangerous icy conditions on surfaces near the drain and may cause damage to the vent system and/ or
the building exterior. We will
NOT
be held liable for any injury or property damage due to formation of ice.
