c.For installations utilizing an ST375 square termination cap the last chimney section must not be more than 4-1/2” below the chase top. See Figure 20D.

d.For installation utilizing a TS345/TS345P Square Termination Cap, the uppermost chimney section must not be more than 3” below the chase top. See Figure 20E.

WARNING!

Never install a single wall slip section or smoke- pipe in a chase structure. The higher temperature of this single wall pipe may radiate sufficient heat to combustible chase materials to cause a fire.

WARNING!

Detailed instructions for installation of the chase top, storm collar and termination cap are packaged with these parts. To avoid danger of fire, all instructions must be strictly followed, including the provision of air space clearance between chimney system and enclosure.To protect against the effects of corrosion on those parts exposed to the weather, we recommend that the chase top be painted with a rust-resistant paint.
