b.Align weld seams in pipes and use a slight twisting motion to FULLY insert male end into female end of joint. Ensure bead in male end of pipe is below locking band and rest against the end of the female pipe. Verify the factory- installed gasket is not dislodged or cut.

c.Tighten locking band by HAND with a 5/16" nut driver until snug plus ¼ turn. DO NOT SECURE JOINTS WITH SHEET METAL SCREWS OR POP RIVETS. DO NOT PUNCTURE THE VENT SYSTEM!

d.Once the installation is complete, operate appliance and inspect all joints to ensure that flue gases and/or liquid condensate will not escape.

G.Install Vent Pipe, Burnham Gasket-Less & Gasketed Vent System.

1.Procedure for joining the male end of Burnham Gasket-Less Vent with the female end of Burnham Gasketed Vent. See Figure 10C.

Figure 10C: Burnham Gasket-Less Male and

Gasketed Female Vent Joint Detail

a.Clean the male end of each joint using an alcohol pad to remove any dirt and grease.

b.Apply a continuous ¼ inch bead of sealant around male end of joint no more than 1/8 inch from end.

c.Align weld seams in pipes and use a slight twisting motion to FULLY insert male end into female end of joint. Ensure bead in male end of pipe is below locking band and rest against the end of the female pipe. Verify the factory- installed gasket is not dislodged or cut.

d.Smooth sealant around joint for a continuous seal. Reapply sealant if necessary.

e.Tighten locking band by HAND with a 5/16" nut driver until snug plus ¼ turn. DO NOT SECURE JOINTS WITH SHEET METAL SCREWS OR POP RIVETS. DO NOT PUNCTURE THE VENT SYSTEM!

f.Once the installation is complete, operate appliance and inspect all joints to ensure that flue gases and/or liquid condensate will not escape.

2.Procedure for joining the female end of Burnham Gasket-Less Vent with the male end of Burnham Gasketed Vent. See Figure 10D.

Figure 10D: Burnham Gasket-Less Female and

Gasketed Male Vent Joint Detail

a.Clean joints of pipe or fittings using an alcohol pad to remove any dirt and grease.

b.Slip a locking band over female (bell) end of pipe/fitting.

c.Apply a continuous ¼ inch bead of sealant around male end of joint no more than 1/8 inch from end.

d.Align weld seams in pipes and use a slight twisting motion to FULLY insert male end into female end of joint.

e.Smooth sealant around joint for a continuous seal. Reapply sealant if necessary.

f.Slip the locking band over joint and align closest bead in locking band with bead in male end of pipe.

g.Tighten locking band by HAND with a 5/16" nut driver until snug plus ¼ turn. DO NOT SECURE JOINTS WITH SHEET METAL SCREWS OR POP RIVETS. DO NOT PUNCTURE THE VENT SYSTEM!

h.Once the installation is complete, operate appliance and inspect all joints to ensure that flue gases and/or liquid condensate will not escape.

H.Horizontal (Through Wall) Vent Installation.

1.Maintain minimum ¼ inch per foot slope in horizontal runs. Position weld seams in vent pipes in all horizontal runs at the top to avoid condensate from lying on the seams.
