Can I put insulation around the vent pipe on a hot water heater?

How do I explain this briefly? I bought a home that was built in 1990. It has a gas water heater that was placed in the garage. I'm thinking that the bonus room above the garage was not finished when they installed it. Since then the bonus room has been finished. The long and short of my question is the exhaust vent is exposed in the closet they built. Right near the front of the door. Whenever we go in there there is a great possibility that we end up hitting our skin on it and it is very hot. The pipe is double lined but can I add fire retardant insulation around the pipe to safe guard our skin? Any suggestions?

Insulation directly on the type-B vent is not acceptable but neither is the situation you have. What you really need is a chase around the stack using standard framing materials and a minimum of 1/2 inch plasterboard. All the materials need to be a minimum of one inch from the stack.
