C. Outside Air
A source of air (oxygen) is required in order for combustion
totakeplace.Whateverairisconsumedbytheremustbe
replaced through cracks around windows, under doors, etc.
Mostnewlyconstructedhousesorexistinghomesttedwith
tightly sealed doors and windows are relatively air tight. In
this case, an outside air source must be made available to
feed combustion air from outside the home.
The Constitution Fireplace comes equipped with an outside
air intake to feed combustion air from outside the home,
along with an outside air termination cap. The 6 in. (152 mm)
solid/expipeisnot supplied.
Outsideairisrequiredto minimize the effects of negative
pressure within the structure. It is recommended to utilize
theshortestductruntooptimizetheperformanceoftheOut-
sideAirextubing.Theoutsideairinletthimbleshouldbe
positioned above the ground level, and must remain clear
ofleaves,debris,iceand/orsnow.Ifyouliveinanareathat
experiences deep snow levels, this must be taken into con-
sideration when determining the height placement above
ground level. It must be unrestricted while unit is in use to
prevent room air starvation which can cause smoke spillage
andaninabilitytomaintainare.Smokespillagecanalso
set off smoke alarms.
This replace will operate correctly only if adequate
ventilation is provided to allow proper draft to the re-
place system. Hearth & Home Technologies assumes
no responsibility for the improper performance of the
replace system caused by inadequate draft due to
environmental conditions, down drafts, tight sealing
construction of the structure, or mechanical exhaust-
ing devices which create a negative air pressure
within the structure where the replace is located.
NOTE: OUTSIDE AIR IS REQUIRED.
An outside air control handle allows you control of the out-
sideairinlet.Thismaybeclosedonlywhenthereplaceis
notinusetopreventcoldairinltration.Useofoutsideair
