3f Venting — direct exhaust — installation

1. Do not mix types or manufacturers of vent materi-

Figure 13  Direct exhaust vertical venting

als.

 

2. Clean all joints before sealing. See vent manufactur-

 

er’s instructions for cleaning and sealing joints. Use

 

their specified sealant. Do not use screws.

 

3. Install vent pipe with seams on top of vent horizon-

 

tal runs. Follow requirements in Section 3e for vent

 

termination.

 

4. Maintain minimum 2” clearance from combustible

 

materials to vent pipe.

 

5. Vertical venting — See Figure 13. Follow vent

 

manufacturer’s instructions for venting through

 

roof.

 

• Vent pipe must extend through roof flashing,

 

jacket or thimble.

 

• Vent may pass through floor, inside wall or

 

concealed space when installed according to

 

vent manufacturer’s instructions.

 

Sidewall venting — See Figures 14 and 15.

 

Vent must terminate at least one foot above

 

anticipated snowline. Vent must be terminated

 

only with:

 

• Tee or elbow with integral screen. (Tee may be

 

mounted either vertically or horizontally. DO

 

NOT use horizontal tee with CGi-7 or CGi-8.)

 

• Elbow and termination coupling with screen

 

(not available for StaR-34).

 

6. Do not seal vent pipe (slip connector for Saf-T Vent)

 

to inside or outside plate.

 

7. If passing through noncombustible wall, provide

 

hole diameter large enough to insert the vent pipe

 

Figure 14  Direct exhaust sidewall venting

(slip connector for Saf-T Vent).

 

8. Install horizontal drain tee as close as possible

 

to boiler, in first horizontal run. See Figures 13

 

and 14.

 

9. Do not exceed the maximum vent system length

 

given in Table 4, page 15.

 

Condensate drain line — use only silicone tubing rated

 

for at least 400°F for the first 18” of condensate drain

 

line, then other non-metallic tubing may be used. Us-

 

ing any other material could cause flue gas leakage,

 

potentially resulting in severe personal injury, death or

 

substantial property damage.

 

On some installations, the condensate drain fitting may be omitted, provided:

•Vent manufacturer shows this option in their instruc- tions.

•Vent is sloped toward termination as shown in dotted lines in Figure 14.

•The vent is installed per Weil-McLain and vent manufacturer’s instructions.

•Condensate drippage from such vents may accumu- late on the ground below. Consider traffic in the area to avoid hazard due to ice accumulation.
