GRAVITY DISTRIBUTION KIT
The Gravity Distribution Kit (FP4-300) may be used to heat rooms located above, behind and either side
of the room where the fireplace is located. Note that, if the hot air outlets are located at various levels, the heat
will tend to seek the one at the highest level.
Installing the Gravity Air Duct System
1. Remove the 7” (178 mm) knockouts in the top of the appliance. Cut the insulating wool and remove the
inner knockouts. Solidly attach the duct adaptor (FP4-302) to the appliance.
2. Always provide a minimum 2” (51 mm) clearance between the hot air duct and any combustible materials
and a 6” (152 mm) clearance between any hot air outlet (FP4-034) and the ceiling. (Figure #17)
3. Direct the gravity heating ducts upward or horizontally. Never direct a duct downward.
This system must never be connected to a forced air heating system. If the heating system’s blower
were to malfunction, the fireplace enclosure would overheat. Valcourt makes a system specially designed for
use with forced air heating systems. (Figure #18)
The dimensions recommended for the Gravity Distribution Kit are the following: minimum height of
35” (889 mm) from the base of the fireplace to the centre of the hot air grill and a maximum of 10’ (3 m) from
the top of the appliance. The hot air grill must be installed at minimum height of 60” (1.5 m) from the floor of
second floor. (Figure #17)
WARNING: It is mandatory to install hot air gravity kit when installing cast iron front option.
FORCED AIR DISTRIBUTION KIT
The Forced Air Distribution Kit can be used to heat adjacent rooms or lower floor located up to 50’
(15.2 m) from your Valcourt Fireplace. Only 6” (15 cm) flexible isolated duct can be use for this installation.
(Figures #17 and 18)
If the fan is installed with a rheostat, the operation is manually control. The fan can be install with the
thermo-disc located under fireplace’s floor, it start automatically when fireplaces floor reach 110°F (43°C). In
cooling cycle the fan stops automatically when the fireplace temperature gets under 110°F (43°C).
The Forced Air Duct System can be installed in one of two ways
1. Install the flexible duct and connect it to the adaptor attached to one of the fireplace’s two side openings.
Install the duct system leading to the adjacent rooms on the lower floors. The fan can be installed anywhere
in the house except in the chase. If the fireplace is in a small room, the central fan can be used to draw and
redistribute excess heat throughout the house. Be careful where you install the fan, so its noise will not be a
nuisance. The length of the duct from the fireplace to the farthest hot air grill must not exceed 50’ (15.2 m).
A certain loss of heat is to be expected at this distance. A plastic duct may be connected to the fan’s outlet
as long as the duct’s heat resistance is at least 250°F (121°C). Never install a plastic duct in the fireplace
enclosure.
