#1 Q:   I am assuming since creosote can build up in the flue....can it also build up in the fan housing and on the blades? How often, and how do you clean it out?
A:   Per the installation manual: Depending upon the type of wood burned, the fan must be removed from the vent pipe and cleaned at least once per year. Soot and creosote build up must be removed from both the fan wheel and housing. The fan motor is permanently sealed and requires no oiling.

#2 Q:   Can this be used horizontally? I do not have much vertical pipe due to warming oven.
A:   Per the installation manual: The Auto-Draft may be mounted on horizontal, vertical or inclined vent pipes. Installation on horizontal vent pipes must be made on the underside of the pipe to prevent excessive heat build up within the fan housing.

#5 Q:   Will this fit a single wall 6 stove pipe?
A:   The Auto-Draft requires a straight section of single wall stove pipe for installation. You must maintain an 18 inches clearance from combustibles to the AD-1 housing. For 5 to 8 inch pipes.

#6 Q:   hello, I am looking to tie into a double walled pipe, wondering if it can be done. Its inside.
A:   It cannot be used on double wall, a section would need to be rep[laced with single wall at point of installation.

#7 Q:   Can I mount this anywhere along the chimney pipe? Does it work with dual wall 6 pipe?
A:   It must be mounted in accordance with Tjernlund directions..2 feet from stove or combustible materials. It also must be installed in single wall pipe, so if the system is double wall, the fan must be in a single wall section.

#9 Q:   Can you wire an appliance cord to it and just plug it in?
A:   Yes, provided it is a grounded cord and is kept from hot surfaces.

#10 Q:   Should this be installed at the highest (indoor) part of pipe ? How does the elec wiring handle the heat from the pipe ?
A:   The wiring must be kept from contact with the pipe and the fan needs to be far enough from the stove to not be exposed to more than 104 degrees. Other than that there are few guidelines.
