1. Insulation selection

• Interior diameter of insulation sleeve must match exterior diameter of pipe.

• Pipe insulation must have a minimum R-value of R-3.

• Must have vapor retarder.

• If installed outside needs to be UV-protected.

2. Clearance from combustibles

• Pipe insulation must have a clearance of 6 inches away from single-wall vent pipe.

• 1 inch away from B-vent pipe to prevent a fire hazard.

3. Installation

• Install continuous insulation on the first 6 feet of both hot and cold water lines from the water heater, including elbows, unions and other fittings.

4. Insulate fittings

• Install prefabricated insulation fittings at elbows and tee's, or fabricate on site.

• Fittings insulation must be tight and continuous.

5. Secure pipe insulation

• Install pipe wrap clips or zip-ties as needed to secure all fittings and seams.

• Lateral seams should be secured at a minimum of every 12 inches (manufactured adhesive seam seal is NOT sufficient).

6. Outside conditioned space

• Follow steps 1,2,4,& 5 to install continuous insulation on all water lines outside the conditioned space to prevent freezing.
