CEILING CLEARANCE
Ceiling clearance is the distance from the top of the fire-
place to the ceiling.
Under no circumstances is the distance between the ceil-
ing firestop and the top of the framing guide to be less
than 38 inches.
OUTSIDE AIR DUCT
After the fireplace is correctly positioned, connect the
combustion air inlet duct to the outside. A 4 inch diame-
ter can be use if the total run of the pipe is less than 25
feet. If the total run is longer than 25 feet, a 5 inch diam-
eter flexible pipe must be used.
1. Use the side or back outside air outlet.
2. Find a convenient location for
the combustion air duct and
intake air hood. The location
of the intake air hood may be
above or below floor level
(see Figure 7). Under no cir-
cumstances should the com-
bustion air inlet be placed in
attic spaces.
3. Make a 4 1/4" (5 1/4" if using
a 5" diameter duct) hole in the
outside wall of the house.
Mount the register in the hole
from the outside with the inlet
facing down.
4. Place the flexible duct over
the intake air hood tube.
Carefully pull back the insula-
tion and plastic cover, expos-
ing 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 to the end of
flexible duct in place with a 2" aluminium duct tape.
CAUTION: When running duct around corners, make
certain no crimping that would restrict the combustion air
flow occurs.
You must use an insulated duct rated at over 200°F. Our
testing has shown that as long as the 5" diameter insula-
ted duct is utilised properly, there is no restriction on the
length of the run. It is recommended that the duct does
not exceed 12 ft. vertical height 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 shall not terminate
in attic spaces.
CHIMNEY
This fireplace is certified for use with 8" ICC model Excel
chimney. The chimney system height from the top of the
fireplace must be a minimum of 12 ft. and a maximum of
28 ft. The minimum system height of 12 ft. must be
increased by approximately 1 ft. for every 2000 ft. eleva-
tion 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
must terminate at least 15 ft. from the top of the fireplace
(12 ft. + 3 ft. for the 6000 ft.). See table #1 bellow for
more precise recommended flue heights.
CHIMNEY INSTALLATION
NOTE: The clearance between the chimney and com-
bustible material must be 2" or more. DO NOT fill this
area with insulation.
