Corr/Guard

Grease Laden Vapors, Heat, Moisture, Make-up Air.

Flue: AL29-4C High, Corrosion Resistant Stainless Steel
Casing: Aluminized / Stainless Steel (NIA - Singlewall)
Pressure: Positive -0- Negative
Insulation: Doublewall - 1" Airspace

NOTE: See temperature limitations.

Venting system design may be limited by appliance performance. Consult appliance installation instructions to determine limitations such as maximum horizontal length, maximum vertical height, elbow and offset limitations, and number of appliances permitted in a common vent.

Material Selection

* AL29-4C Superferritic stainless steel or equivalent.
** CTO: Configured To Order. The 1st digit identifies the flue material, the 2nd digit identifies the casing material, and the third digit indicates "Air insulated".

Design Considerations

When venting gas appliances always consult the appliance installation instructions. Horizontal runs, elbows, offsets, vertical height, etc. may be limited.

HORIZONTAL RUNS:
Slope must be at least 1/4" : 12" (6mm : 305mm). Neutral or negative pressure installations must slope upward, away from the appliance. Positive pressure systems may slope upward or downward. Always provide for condensate drainage where required.
