Roof Top Unit Mounted In Wood

Table 1507 8 wood shingle and shake installation.

Roof top unit mounted in wood.

Prior to setting the unit onto the curb the installer should ensure that a sealing material is positioned between the unit and the curb to provide a watertight connection. The roofscreen equipment screen system was developed to solve problems associated with structural steel wood steel stud and unit mounted roof screen approaches. Additionally ahu s will often be connected to central plant such as chillers and boilers to provide the heating and cooling but rtu s are self contained and have everything they need all in one unit. The unit frame shall be mounted on two 1 8 thick tubular steel mounting rails with fork lift cutouts.

They have no chance against a high wind event. Such air cooled roof top unit is. The welding techniques shall be either t joint or corner joint with a 1 16 bead. Placing the unit on lumber which bears on a sloped roof causes the equipment to sit out of level and operate less efficiently.

The rooftop unit may be mounted immediately after the curb is installed. The installation of wood shingles shall be limited to roofs where the allowable uplift resistance is equal to or greater than the design uplift pressure for the roof in compliance with section 1504 1. The attachment of the stand to the roof deck also needs to be designed to resist the design loads in addition to anchoring the base. Since 2004 roofscreen has increasingly become the gold standard for architects facilities managers contractors and building owners for equipment screening needs.

The cabinet construction shall be of 18 gauge sheet steel. Roof top unit is a a c unit installed outdoor. Roofi ng may be completed after. The product approval shall state the allowable uplift resistance for the attachment system.

Installation is much easier compared to cases whereby water is used as the cooling medium. Combining industry leading efficiency with fast easy installation and service lennox continues to offer reliable systems that deliver exceptional comfort in commercial buildings. The unit frame shall be of 14 gauge tubular steel mig welded and qc inspected for rigidity and shape. Lennox packaged rooftop units represent some of the most innovative technology in the market.

The usual method is to mount the unit on wood blocking to raise it above the plane of the panel ribs and give it a surface to bear upon. In cases whereby air is used as the cooling medium in the condensing unit site. Material gage to support the unit load will be furnished with the curb. The base of the condenser unit should be anchored to the equipment stand and the stand should be attached to the roof.

Rooftop mounted condenser units are often placed on wood sleepers that simply rest on top of the roof system. It may also migrate if not anchored.
