10. Install a vertical pipe, or if all requirements for direct venting are met, install vent termination. The stainless steel cap
termination manufactured by the vent manufacturer is recommended. However, when the vent terminates several feet
above ground level and there are no trees, plants, etc. within several feet, a 45° elbow can be used as termination. The
elbow must be turned down to prevent rain from entering.
NOTE:
• It is recommended that horizontal through wall installations have 3 to 5 feet (91 to 152 cm) of vertical pipe in the system
to help naturally draft the unit in the event of extreme weather or a power outage.
• Some horizontal through wall installations may require a “T” and 3 to 5 feet (91 to 152 cm) of vertical pipe outside the
building to help draft the unit. This may be required if a proper burn cannot be maintained, after the stove has been tested
and the airflow set. This is due to the back pressure in the exhaust caused by airflow around the structure.
• Follow vent manufacturer guidelines for installation of venting. High temp sealant must be used when connecting vent pipe
to the unit’s starter pipe. Improper seals at the vent joints may cause combustion by-products to leak into the room where
installed -
seal as required.

A termination cap is always recommended for this type of install but a stainless steel termination hood or a 45° elbow may
be used in place of the cap.
Figure 12 is the recommended installation set up, venting length is negligible.
Figure 13 is the installation to use if there is a concrete or retaining wall in line with exhaust vent on a pellet stove. The
termination must be 12” (30 cm) from the outside wall and 12” (30 cm) above the ground.
