3.3.10 Flue spillage test
A flue spillage test is recommended as part of this installation and should be performed by a qualified
service person only. Hereafter, periodically check the vent draft.
1. Close all the doors and windows in the room.
2. Start all the exhaust fans in the home.
3. Light the heater to the full fire position.
4. After five to ten minutes, insert a match inside a draft duct opening and ensure that the flame
wisps and smoke are drawn into the duct at the front corner (see Figure 9).
5. If the flame wisps are not drawn into the ducts (see figure 10), turn the heater off, and determine
the cause of the lack of draft.
Do not operate the heater until there is sufficient draft.
