Danger: Fumes
Salda Antifrost system uses dis-balancing of the air ow and it may cause negative pressure in premises. Great care should be taken
when using at the same time in premises as another heating appliance what depend on the air in premises. Such appliances include
gas, oil, wood or coal-red boilers and heaters, replaces, continuous ow or other water heaters, gas hobs, cookers or ovens which
draw air in from the room and duct exhaust gases out through a chimney or extraction ducting. The heating appliance can be starved
of oxygen, impairing combustion. In exceptional cases harmful gases could be drawn out of the chimney or extraction ducting back
into the room. In this case we strictly recommend to turn o󰀨 Salda Antifrost and use an external preheater for heat exchanger anti-frost
protection (see Salda Antifrost function on the Remote controller manual).
