• To fit in existing cavity wall make hole through full cavity wall by using 127-130mm core drill ensuring a small incline towards the outer wall and remove brickwork debris to fit vent.
• Large flanges around the external cowl and internal grille allow minor irregularities to be covered easily and adequate fixing. External cowl will push onto sleeve and can be silicone sealed to face or screw fixed.

• State the correct anti-draught ventilator for the heating appliance to be vented or background ventilation required.
• State the required colour of external cowl and/or grille.
