 Exhaust and combuson air piping must be securely

fastened to structure every 4 feet, to ensure

dimensions shown in the Figures throughout this

document are maintained.

 strap vercal vent too ghtly as the strapping

must permit the vent to move in the event of

expansion and contracon.

 Straps are eld supplied. Use straps, clamps or equiva-

lent that will not score or damage the pipe. Expansion

and contracon should be addressed between appli-

ance and terminaon point.

 All penetraons must be sealed according to local

building codes. Caulking for side wall terminaons and

ashing for roof penetraons are typical. Use only PVC/

CPVC compable sealing material. Contact PVC/CPVC

manufacturer for a list of compable materials.

 For installaons with mulple terminaons, maintain

appropriate clearances between terminals. (Reference

IPEX Concentric Vent Kit Clearance diagram)

 The pipe length of the concentric vent kit can be

shortened; providing that the cung and cemenng

procedures adhere to the System 636 guidelines;

reference IPEX installaon instrucons for further

informaon.

Moisture in the ue gas will condense as it leaves the

vent terminal. In cold weather this condensate can freeze

on the exterior wall, under the eaves, and on surrounding

objects. Some discoloraon to the exterior of the building

is to be expected. However, improper locaon or

installaon can result in damage to the structure or

exterior nish of the building.

Danger of re or bodily injury – Solvent cements and

primers are highly ammable. Provide adequate

venlaon and do not assemble near a heat source or

open ame. Do not smoke. Avoid contact with the skin or

eyes. Observe all cauons and warnings on material

containers.
