control logic) for any common air intake/exhaust applications.
4. The pressure drop across an exhaust pipe shared by multiple boilers
must have a negative pressure at all operating conditions up to -0.05" wc.
A mechanical draft assist system, such as a variable speed fan, may be
required to accomplish this.
5. Combustion air dampers and/or a variable speed exhaust fan may be
required. Please contact your venting manufacturer for proper vent size
and arrangement.

Venting Terminations

Adhere to the following for installation (see Figure 10):
1. All vent pipes and ttings must be installed with appropriate air space
clearances to combustibles. These air space clearances apply to indoor or
outdoor vents—whether they are open, enclosed, horizontal or vertical or
pass through oors, walls, roofs, or framed spaces. The air space clearances
should be observed to joists, studs, sub oors, plywood, drywall or plaster
enclosures, insulating sheathing, rafters, roo ng, and any other material
classed as combustible.
2. The required minimum air space clearances also apply to electrical wires
and any kind of building insulation.
3. Adequate provision must be made to support the weight of the exhaust
venting. It cannot be supported by the boiler exhaust connection.
4. Listed termination parts must be used.
5. Select the air intake point of penetration where a minimum of 1/4" per foot
upward pitch can be maintained.
6. When penetrating a non-combustible wall, the hole through the wall must
be large enough to maintain the pitch of the vent and provide sealing. Use
adhesive material to seal around the vent on both sides of the wall. When
penetrating a combustible wall, a wall thimble must be used. See Figure 11
for installation instructions. Minimum wall thickness through which vent
system may be installed is 3.25 inches (82.5 mm). Maximum wall thickness
through which vent system may be installed is 20 inches (508 mm).
