Closure valve
If you decide to connect separate combustion air it is mandatory to install a
closure valve to prevent condensate formation and to prevent the room from
becoming cold while the stove is not in use. It should ideally be located as
close as possible to the outside wall. It can be controlled from inside if it is
not too far from the stove (cable length = 47”).
Please note that the infiltration of wind, weather , snow and water can effect or
damage the air combustion system.
- Ideally be fitted with a butterfly valve so that it can manually , be used to close the
cold air from entering the firebox.
Please note that the butterfly valve has to be 100% open or 100%
closed and should not!!!
Be used to adjust burn rate.
Try to keep the butterfly valve as close to the outside wall as possible.
- The air-duct should be insulated and the distance from the fireplace to the outside
should be as short as possible.
For 5” air duct please refer to the maximum lengths and elbows.
Number of elbows
4’ 4 elbows
8’ 4 elbows
10’ 2 elbows

If you exceed these guidelines, you must compensate by using a larger diameter and/
or a smoother duct. Careful not to crush the duct!
It should ideally be located as close as possible to the outside wall.
- If it is not possible to bring in combustion air to the fireplace please insure that there
is sufficient air to feed the fireplace in the room –please note that this is not ideal.
