Sidewall Venting - Thermo Pride CLQS1-050T36N Installation And Operation Manual

All installations and services must be performed by qualified service personnel.
F. SIDEWALL VENTING
NOTICE: If the furnace has an overall equivalent vent length of 50 feet or less, it may use the
sidewall termination described in Section 1. If the vent length is greater than 50 feet, up to the max
length allowed, these units should use the termination described in Section 5 for a sidewall
termination.
Vent and combustion air pipes may pass through a maximum wall thickness of 18 inches. The
1.
minimum wall thickness is 2 inches. Referring to Figure 1, the maximum distance from the outer
wall to the center of the elbow is 12 inches.
NOTICE: If exterior sidewall building materials are subject to degradation from contact with flue
gases or moisture, a minimum 24-inch diameter shield shall be fabricated from stainless steel or
UV-resistant plastic sheet. The protective shield shall be installed around the vent pipe on the
outside wall.
The exhaust vent termination elbow shall be installed in accordance with these instructions and
2.
any applicable local codes. Refer to Figures 1 and 2 for typical examples of proper terminations.
a. The exhaust vent termination must be installed in the same atmospheric pressure zone (i.e. on
the same wall) as the air intake termination.
b. The bottom edge of the vent termination elbow must be installed at least 12-inches above the
outlet of intake termination elbow.
c. The horizontal distance between the inlet and exhaust terminations should be minimized, when
possible, and should never exceed 24-inches.
