Just like with every appliance, your gas water heater maintenance should be performed on regular basis. Neglecting it can compromise water heater’s operation.
Gas burning appliances vent pipes produce heat when discharging exhaust gases to exterior.
Temperature of the vent pipe is transferred to the surrounding area and all the materials that are in the vent pipe vicinity. Problems start arising if those materials are combustible and located to close to the furnace, water heater vent pipe. If you apply heat to a combustible material for some period of time (that varies between materials), its point of ignition will gradually get lower and eventually little heat will be required to start a fire – that’s why you need a clearance between the vent pipe and a combustible material.
WH PVC vent pipes can be used only with power-vent /exhaust motor equipped hot water heaters also known as an induced draft gas water heaters (also CPVC and ABS but some manufacturer and local restriction may apply to all 3 types).
