Jun 04, 2003 · A Category I vent system works by allowing heated flue products to rise vertically, so the vent pipe must rise vertically from the boiler vent connection as soon as possible. You should also limit the length of the horizontal flue pipe. All horizontal runs of vent pipe must rise 1/4 inch per foot of run to maintain proper draft in the vent.
Create an airtight seal at each joint in the exhaust and intake air pipes from the water heater or boiler collar to the vent termination. Set the temperature setting to the same value on all water heaters or boilers that are sharing a common vent system. Ensure that all water heaters or boilers Common Vent System Installation ManualCreate an airtight seal at each joint in the exhaust and intake air pipes from the water heater or boiler collar to the vent termination.

Gas Water Heater and Furnace Chimney Flue Size Nov 17, 2008 · To make it simple if you have a gas water heater with a 3 draft hood, and a furnace with a 4 flue collar connected to the same chimney flue, youd calculate that chimney flue size based on the 3 draft hood the smaller of two. So lets calculate or why dont we skip those calculations and Ill give you the answers:
Mar 15, 2014 · Even if someone had their water heater set at 120 F, with scaling, the flue gas temperatures can rise well above 300 F. Boiler thermostats or burner controls are generally limited to 200 F, commercial water heater thermostats or burner controls to 180 F and residential water heater burner controls to 160 F, and all can overshoot by several degrees. Minimum slope for water heater exhaust flue? - Inspecting Jun 13, 2008 · gas-fired water heater 1/4" per foot. Right? Oil-fired WH? Gas-fired furnace? Oil-fired funace? Kenton, all the installation instructions, for any of the above, that Ive ever seen were a minimum of 1/4" per foot but I dont have a code reference handy.
Traditional gas-fired, forced-air furnaces produce hot combustion exhaust gasses and therefore need metal vent pipes, or chimneys. In contrast, modern high-efficiency condensing furnaces exhaust much cooler gasses and need only plastic pipe materialssuch as PVC, CPVC, or ABSfor their exhaust vents.Some high-efficiency furnaces also include a plastic pipe for intake area, and all types PolyPro® - DuraVentPolyPro is a polypropylene vent pipe for use with ANSI Category II and IV gas-burning appliances, including highefficiency water heaters, condensing boilers and warm air furnaces. Poly Pro is listed by Intertek to the ULC S636 standard in Canada as a Class IIA, IIB and IIC vent system suitable for exhaust temperatures up to 230°F / 110°C, and
For the newly installed water heater, the gas pipe might be filled with air and cannot be ignited for the first time. Please repeat on&off to exhaust the air until water heater is finally ignited. 4. In some place, the water pressure may be too strong and thus water can not be heated. In this case, please turn down the water-in valve.

The difference is that a power vent water heater pulls in combustion air from the space around the appliance, then uses a fan to propel the exhaust through the vent. A direct vent system pulls in Why do gas water heater exhausts have an air gap before The draft will change in the chimney as exhaust vents towards it especially when going from cold air to hot. A draft hood is placed above the upper most part of the gas furnace to draw air into the chimney and makes it possible to draw more or less air through the chimney as necessary to create a constant flow.
Any exhaust termination that exceeds the envelope of the house more than 2' is required to be insulated by code so prevent freezing from happening. Another problem may be that the pipe is not sloped back to the appliance, and there may be an elbow that holds condensate water and freezes during the off cycle of the water heater.Water Heater Venting Parts - The Home Depot3/4 in.
