THERMOSTAT (option)
If you want constant heat, day and night, you will be sur-
prised of what the wall thermostat option can do for you.
Once you have your fire burning, just set the manual con-
trol on low (push the draft control lever all the way to the
left) and let the automatic thermostat take over. Your
room temperature will keep as even as though you were
heating with oil, gas, or electricity - except you will find
wood heat more comfortable (see Options: Wall
Thermostat part FDHC4).
NOTE: This thermostat controls the combustion air rate,
not the internal circulating blower.
INTERNAL CIRCULATING BLOWER (option)
If you have the optional internal blower installed, adjust
the speed of the blower to the output you require. The
blower speed control should have been installed at a
convenient place on the wall. When a fire is burning, the
thermo disc installed inside the fireplace will turn on at
110° F, allowing the blower to operate; this will take about
20 minutes from the time you start the fire. When the
Delta cools to 90°F, the switch deactivates the blower.
The maximum heat output of the fireplace is greater with
the blower running (see Options: Circulating Blower part
FDHB5-N).
GRAVITY VENT SYSTEM (option)
If there are areas in your home that you would like to
heat either in an upper level or an adjacent room, the
gravity vent system can provide this heat with or without
the use of a blower. It is controlled by a gravity vent
damper. The handle is located above the top left louvers
of the fireplace. Simply turn the lever to adjust the air
flow through the gravity vent ducting. As the hot air rises,
it will be distributed through the insulated ducting to the
outlet (see Options: The Gravity Vent System part FDVD,
page 24).
CENTRAL HEAT SYSTEM (option)
You have the option to heat remote rooms in your home
from the heat generated by your fireplace. If this option
is installed, there may be a thermostat installed in the
main room you want to heat, away from the room that
contains the fireplace. Or a thermostat installed that
removes heat from the fireplace when the main room you
are trying to heat reaches the desired temperature. This
thermostat controls the blower, which brings air to the
other rooms in your home, keeping them at the tempera-
ture you desire. When the blower is running, it takes air
from the room the Delta is in, draws it around the fire-
place and distributes it (see Options: Central Heating
System parts FDHC6/FDHB6).
NOTE: The blower (part FDHB6) can push warm air
either up or down, and can also be zone controlled (see
Options: Zone Heating and diagrams).
HINT: If some evening you would like to enjoy the ambi-
ence of the wood flame, but you are a little too warm, turn
up the central heating thermostat and open a window in
the room the ducting goes to. This will keep your room
in front of the fire from getting too warm.
OPERATION
THE FIRST FIRE
Before the first fire, be absolutely sure to wipe off all fin-
gerprints and debris from the gold plating, if you have
chosen this option. The plating undergoes a sealing
process during this first fire, and the acid from your finger
prints will permanently etch the gold plating. You will
experience a slow start-up during the first fire. The
refractory bricks still contain moisture and take a good
hot fire to get rid of the moisture. While there is moisture
in the bricks, the bricks will be black with smoke deposits.
When the moisture is gone, the bricks will turn white.
You will experience an odour during the first few fires.
This odour results from the curing paint and the burn-off
of oil from the heat exchanger. Ventilate room to expel
odours.
LIGHTING
Slide the draft control that is located above the lower
right side louvers all the way to the right. Light a fire in
the fireplace, starting with paper and kindling only. Then
add 2-3" diameter wood. After the fire is established,
close the doors to prevent overheating of the fireplace
face. The unit is designed to accept combustion air
through the outside air duct only. (See the Combustion
Control System, page 5) Never use any flammable liq-
uids. Once a coal bed is established, add standard cord
wood. Leave the draft control open until the fire is well
lit, then adjust it to the level you desire.
Warning: Do not use a grate or elevate the fire.
REFUELLING
Fuel wood can be of any species. However, ensure that
the wood is well seasoned and kept under cover.
NOTE: The central heat and internal blowers, if installed,
should be shut off during refuelling to prevent smoke
from spilling out of the fireplace.
The door should be opened slowly to keep smoke from
spilling into your room. If you do have smoke spillage,
check to see that all kitchen and bathroom fans have
been shut off. They can cause a vacuum in the house,
which pulls smoke out of the fireplace.
