Will Air Vent specify a type of fastener for The Edge Vent?

The fastener must penetrate the underside of the roof deck.

Air Vent will not specify a particular fastener to be used for the installation of The Edge Vent or for shingles installed over the product because of possible variations in the construction details. Air Vent does specify that the roofing nail used to secure The Edge Vent to the roof deck AND to install the shingles over the vent be of sufficient length to fully penetrate the underside of the roof deck. However, Air Vent recommends that the fastener must be at least 1-3/4" long but please confirm in the field if that length is sufficient.
