Any exterior venting (vent pipe exposed to outside ambient temperatures) should be kept to a minimum, due to potential condensation problems. This is especially important in high humidity cold weather climates, such as maritime areas, lake shores, and low river valleys.

- Page 13 The chimney should be cleaned and or inspected before installation. Figure 4.7 36” Figure 4.5 Creosote - Formation and Need for Removal - When wood is burned slowly, it produces tar and other organic vapors, which combine with expelled moisture to form creosote. The creosote vapors condense in the relatively cool chimney flue of a slow-burning fire. As a result, creosote residue accumulates on the flue lining. When ignited, this creosote makes an extremely hot fire. The pellet vent pipe should be inspected at least twice monthly during the heating season to determine if a creosote buildup has occurred. If creosote has accumulated it should be removed to reduce the risk of a chimney fire. Guidance on minimizing creosote formation and the need for periodic creosote removal: The chimney should be inspected during the heating season to determine if a creosote build-up has occurred. If a significant layer of creosote has accumulated (3mm or more) it should be removed to reduce the risk of a chimney fire. Harman® • PF-120 Installation Manual_R1 • 2014 -___ • 03/14 3-90-08121i...

Page 16: Outside Air Installation
Direct Vent Wall Pass-through Kit total house demand. House demand may consume some (Part #1-00-677177) air needed for the stove, especially during a power failure. It may be necessary to add additional ventilation to the space in which the pellet appliance is located. Consult with your local HVAC professional to determine the ventilation demands for your house. To install outside air use 3" non-combustible flex pipe Figure 4.8. There is a break-away hole on the rear panel of the PF- 120 stove which must be removed before connecting the flex pipe. The pipe should be run outside and terminate to the side or below the vent pipe outlet so the flue outlet is more than 12" from the inlet cover. The maximum length run of this pipe is 15 feet. The Inlet cover should be used to keep birds, rodents, etc. out of the pipe Figure 4.8. You may choose to use the optional Direct Vent Wall Pass- Figure 4.9 through Kit which incorporates the venting pass-through and outside air inlet into one component. Figure 4.9.
