bly. Be sure to orient the unit with the manifold facing you. (Fig. 1)

Installation
Incorrect installation or unheeded warnings could result in
a serious fire, and loss of life and property.
Product is NOT designed for installation in “zero-clearance” fireboxes
or mobile homes, or in conjunction with gas log sets.
Inspect the chimney flue and fireplace for loose mortar, damaged
brick, and creosote build-up. Contact a professional chimney sweep or
building contractor for more information or repair.
Slide unit into fireplace opening, making sure to center unit in the
opening. Use feet adjustment bolts to level unit. Make sure insulation
is properly installed; covering all gaps without being bunched up. Note
that large gaps created by rough openings may require additional insulation.
Route the blower cord to desired location. Plug in the cord and check
for proper blower operation. See “Blower” section in Operating In-
structions for explanation of switches.
Operating Instructions
Fuel:
WARNING: Never use gasoline, oil, or any other flammable liquid to
start a fire!
Dry, seasoned hardwood is the safest and most efficient firewood. Rec-
ommended firewood age is 6-9 months.
When wood is green and/or burned very slowly, it produces tar and
other organic vapors, which combine with expelled moisture to form
creosote. This creosote residue accumulates on the flue lining, and
when ignited, can start an extremely hot chimney fire. The chimney
should be inspected for creosote build-up twice monthly during the
heating season, and cleaned as necessary.
Make certain to keep wood well back from the door opening in order to
avoid puncturing or placing extreme heat on the glass.
Regulate the fire in order to avoid the dangers and unnecessary wear
associated with extreme heat and uncontrolled burning.
Ashes should be placed in a metal container with a tight fitting lid and
retained there until all cinders have thoroughly cooled. Remember
that bottom, sides, and handles of container may be very hot.
Blower:
Blower is operated by variable speed switch. To turn on, turn switch
clockwise until desired fan speed is achieved. To turn off, turn switch
counter-clockwise until a positive “click” is heard. Unit is also
equipped with a thermostatically controlled switch which turns
blower off when temperature drops below 90°F.
In event of power failure, only burn unit with doors open.
WARNING: Disconnect power source prior to performing any mainte-
nance or diagnostic operation on the blower or switches!
