CEILING CLEARANCE
The ceiling clearance is the distance from the top of the
fireplace to the ceiling.
Under no circumstances should the distance between
the ceiling and the top of the CHAMELEON be less than
39" (see Figure 4).
OUTSIDE AIR DUCT
After the fireplace is correctly positioned, connect the
outside air inlet to the outside (see Figure 6).
Use an insulated flexible duct rated at over 200° F. It is
recommended that the duct does not exceed 12 ft. ver-
tical rise above the base of the unit.
The air inlet should never be less than 5 ft. below
the top of the chimney flue and must never
terminate in attic spaces.
A 4" diameter duct can be used if the total run of the ducting is less than 25 feet. For longer runs, use 5" diameter
duct. A 4"-to-5" increaser is provided with the fireplace.
1. Find a convenient location for the combustion air duct and fresh air hood. The fresh air hood can be above or
below floor level.
2. Make a 4 ¼" (5 ¼" if using a 5" diameter duct) hole in
the outside wall of the house. Push the hood in from
the outside. Seal the joint between the hood and the
outside wall with an appropriate sealant.
3. Place the insulated flexible duct over the round sleeve
on the outside air hood. At both ends, carefully pull
back the insulation and plastic cover, exposing the
flexible duct. Then at each end, attach the duct with
metal screws to the inlet and tube. Carefully push the
insulation and cover back over the duct. Tape the
plastic cover in place with 2" aluminium duct tape.
CAUTION: WHEN RUNNING THE DUCT AROUND
CORNERS, BE SURE TO PREVENT CRIMPING THE
DUCT THAT WOULD RESTRICT THE COMBUSTION
AIRFLOW.
CHIMNEY
This fireplace is certified for use with 7" ICC Model
EXCEL chimney only. The chimney system height from
the top of the fireplace must be a minimum of 12 ft.
We recommend that the minimum height be increased by
approximately 1 ft. for every 2000 ft. elevation above sea
level. Every 30° or 45° elbow also increases the minimum
height by 1 ft. For example, if you are living 6000 ft.
above sea level, your chimney should terminate at least
15 ft. from the top of the fireplace (12 ft. + 3 ft. for the 6000
ft.). See Table 1 for more precise recommended flue
heights.
