CAUTION:
UNDER NO CIRCUMSTANCES MUST ANY TYPE
OF DAMPER OR RESTRICTION BE INSTALLED IN THE CHIM-
NEY OR CONNECTING STOVE PIPE.
CHIMNEY
Chimney size: 178 mm (8”) diameter or 150 mm x 250 mm (6” x
10”) maximum inside measure masonry chimney.
Metal chimneys must be of a type suitable for wood burning ap-
pliances and masonry chimneys must be lined with an approved
liner.
ARDENT ENERGY heating units burn very efficiently, resulting in
lower than usual flue gas temperatures. For this reason,
outside installation of the chimney is not recommended. Due to
the fact that it will dissipate more heat, an outside chimney will
cause more problems with low draft and excessive creosote ac-
cumulation.
On initial operation of the heating unit a draft reading should be
taken. (Contact your local ARDENT ENERGY dealer for further
information on measuring draft). The draft should measure .06
water column with the unit at normal operating temperature. If
this reading has to be induced by a roaring fire, it is an indication
that draft is inadequate. If the draft is more than .06 a draft
regulator should be fitted to the connector pipe. If the draft is less
than .06 appropriate action should be taken to improve the draft.
eg. a) insulate chimney
b) move unit to eliminate horizontal section
c) add to top of chimney
If an existing chimney is to be used, it must be inspected carefully
for soundness and to assure that it meets the above specifications.
CHIMNEY TERMINATION
Chimneys are required to extend at least 915 mm (3’) above the
highest point where they pass through the roof of the building and
at least 610 mm (2’) higher than any portion within ten feet. In
some cases the chimney must be higher than minimum for enough
draft due to unfavorable geometry of the surroundings.
INSTALLATION OF OPTIONS
WALL THERMOSTAT KIT (MODEL HC2)
The control system consists of an electric damper control unit and
a wall thermostat.
INSTALLATION
1. Remove the 32 mm (1 1/4”) knockout at top left of rear heat
shield. Insert arm through hole and screw the damper control
unit into pre-drilled holes.
2. Remove left hand side shroud by unscrewing 2 screws at
back.
3. Attach one end of ball chain to damper control arm.
4. Attach the remaining end through hole in air intake assembly.
(There should be a slight slack in the chain.)
5. Locate thermostat some distance from heater 3M - 6M (10’ -
20’) but not in another room unless direct venting is provided
for hot air.
6. The thermostat should be set on an interior wall. Follow manu-
facturer’s instructions.
7. The heat anticipator setting should be 0.4 amps.
8. Check chain length by shutting off the manual control and
setting the thermostat above room temperature. The draft
damper should open to maximum.
9. Set thermostat below room temperature; the draft damper
should close completely. Adjust chain length if required.
