Venting — direct exhaust.........................
1. Do not mix types or manufacturers of vent materials.
2. Clean all joints before sealing. See vent manufacturer'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 horizontal runs. Follow
requirements in section
3e
4. Maintain minimum 2" clearance from combustible materials to vent
pipe.
5. — See
Vertical venting
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.
— See
Sidewall venting
least one foot above anticipated snowline. Vent must be terminated
only with:
• Tee or elbow with integral screen. Tee must be mounted vertically.
• 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 (slip connector for Saf-T Vent).
8. Install horizontal drain tee as close as possible to boiler, in first
horizontal run. See
Figure 13
9. Do not exceed the maximum vent system length given in
page 15.
Condensate drain line — use only silicone tubing
rated for at least 400 °F for the condensate drain line.
Using 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 instructions.
• Vent is sloped toward termination as shown in dotted lines in
.
14
• The vent is installed per Weil-McLain and vent manufacturer's
instructions.
Condensate drippage from such vents may accumulate on the ground
below. Consider traffic in the area to avoid hazard due to ice accumulation.
Ice buildup may also block vent.
