The Manthorpe 5” Core Drill Vent is designed predominantly for use when
ventilating a gas appliance, although can
used to supply general through wall ventilation as well
The kit includes a cowl vent for exterior use, a louver grille for interior use,
a 350mm length of pipe duct and an optional anti-draught baffle which reduces
the airflow and also the feel of a draught through the vent.
Without the use of the anti-draught baffle, the free area of the vent is 100cm²,
enough to supply an appliance with a rated input of 27kW or 92,000 Btu/h (in
accordance with BS5440 Pt.2:2000).
With the anti-draught baffle installed, the effective free area of the vent is
reduced to 70cm² (BRE tested) providing enough ventilation for an appliance with
an input rating of 21kW or 71,500 Btu/h.
The vent can easily be fitted in both refurbish and new build situations with
the use of a 5” (127mm) diameter core drill.
