Burnham 1100-H4 manual Horizontal Supports

11.Horizontal Supports:

Saf-T Vent SC must have supports for every six (6) feet of horizontal run and after every transition from vertical to horizontal. Support hangers by themselves do not maintain the necessary clearances to combustible materials; be sure to consider clearances when planning the system.

The supports must be secured to solid material using at least #10 fasteners. Do not fasten supports to drywall sheathing without using hollow wall anchors. The conduit supports must maintain the ¼” per foot pitch to avoid collection of condensate in the vent. Position the vent so that the welded seam is on the top.

0” Clearance Support Clamp, (SC_ _SUP): Attach the bracket to the structure but do not tighten in place. Open the hose clamp and slip it under the support bracket. Position the clamp between the mounting screws and rotate the clamp so that the screw housing will be accessible after the vent is installed. Restart the threads on the hose clamp and securely tighten the mounting screws to the structure. This can also be installed vertically.

1” Clearance Support Clamp, (SC_ _SUP1): Supports the vent at 1” clearance to the structure. Line up the support mounting brackets so that the mounting screws will follow the center line of the vent section. This can also be installed vertically.
