The first flue component on the heater must be a special vertical female/female discharge adaptor. The
centre, exhaust adapter has integrated condensate trap, but the air intake does not. For terminations
straight through the wall the special horizontal adapter for short flue lengths is used. Never use an ex-
tension as the first component, they will cause damage to the water heater and the flue system. Secure
flue connections with pipe clamps or perforated hanger iron. Please see page 29 for recommended ter-
minal positions.
