Model HF85R 4
OPERATION INSTRUCTIONS
ARDENT ENERGY units are especially designed for controllabil-
ity. With the optional thermostat kit, your house will be heated to
within 1 degree Celsius of your thermostat setting.
The following operating instruction MUST BE FOLLOWED
CAREFULLY for satisfactory operation.
FUEL
Do not burn any fuel but wood.
Do not burn driftwood. Salt corrosion is not covered under war-
ranty.
Wood should be dry, however green wood can be burned. It
should be noted when using green wood that:
1. The amount of wood that you need is increased by
approximately 20% when using green compared to
dry wood.
2. The wood has to be in smaller pieces.
3. More frequent fueling is necessary.
4. Creosote formation may increase.
5. The fire has to be started with dry wood until a good
bed of coals is formed.
6. Heat output will be considerably lower.
7. Do not use grate or elevate fire.
BYPASS DAMPER
1. When the bypass damper is open (i.e. bypass rod
pulled out) combustion will take place within the entire
firebox. Operate the heating unit with bypass control
rod pulled out when quick heat is required and when
starting the fire.
2. When desired house temperature has been achieved
push bypass rod in.
3.
Whenever there is a fire burning, the bypass lever
should be open for 30 seconds before the door is
slowly opened.
LIGHTING
Before lighting, the bottom of the unit must be covered with one
inch of sand or ash. After lighting, leave the door open a crack for
a few minutes for the wood to catch then latch door shut. The
bypass should be left open long enough to allow the chimney and
the heater to reach operating temperature and so create a good
draft. Do not use a grate or elevated fire; build wood fire directly
on hearth.
NOTE:
Fire door must be latched shut at all times except when
loading fuel or checking the fire.
MANUAL CONTROL
Turn manual draft control counterclockwise (open) all the way
until unit warms up, then clockwise to adjust temperature to suit.
WALL THERMOSTAT CONTROL
Set the thermostat at temperature desired. When warming up a
cold room there will be an initial temperature overrun, then the
temperature will stabilize.
RELOADING
1. Have wood on hand to load firebox.
2. Open bypass lever for 30 seconds.
3. Open the door SLOWLY. Allow the chimney to draw
off smoke
4. Load wood.
5. Close door and push bypass lever in.
DO NOT OVER-FIRE UNIT BY LEAVING DOOR OPEN EX-
CEPT TO LIGHT AND TO CHECK FIRE.
Operation with door ajar voids warranty.
NOTE:
Cleanest burning conditions occur when the fuel wood
has been reduced to charcoal. To minimize creosote buildup,
load the unit with just enough wood to last until the next loading
time. This will ensure that the fuel is in charcoal form for a good
portion of the burn cycle. Of course, the unit can be loaded to
capacity during extremely cold weather or when extended inter-
vals between loadings are anticipated
.
MAINTENANCE
DAILY
Check chimney and pipe for creosote build-up until experience
shows how often cleaning is necessary. Periodically
(about once week) run unit at maximum with bypass open for 30
minutes to bake any creosote in the chimney and pipes. This
should greatly reduce frequency of cleaning.
AS NEEDED
Any creosote buildup in chimney and pipe over 6 mm (1/4”)
should be removed mechanically. OPEN BYPASS BEFORE
CLEANING CHIMNEY.
ASH REMOVAL
Ashes should be removed once they reach a depth of 100 mm (4
in.) maximum. Let the fire burn out. Protect the area in front of
heater with a non-combustible material. Shovel ashes into a
metal container with a tight fitting lid and leave an inch of ash in
the heater. The closed container of ashes should be placed out-
side on non-combustible surface, or on the ground, well away
from all combustible materials, pending final disposal. If the
ashes are disposed of by burial in soil or otherwise locally dis-
persed, they should be retained in the closed container until all
the cinders have thoroughly cooled.
DOOR
The door is an unique adjustable center push design to ensure
trouble free, air tight operation for years to come. When closing
the door there should be a slight resistance; if not, the door
should be adjusted. To adjust in and out, loosen the top 2 nuts,
move the door in or out, then tighten the nuts. To adjust up or
down, loosen the bottom 2 nuts, move the door up or down, then
tighten the nuts. Lubricate door pawl with high temperature lubri-
cant monthly.
