Why is water heater connected to furnace?
Your furnace or boiler will have a pipe attached to the water heater. This pipe circulates hot water from your boiler to a heat exchanger within the water heater. This exchanger then heats the water in the tank and gives you anywhere from 30-100 gallons of water to use when you need it.

The tankless heater cannot share vent piping with any other appliance, and it cannot use a masonry chimney flue for venting.
Can you vent a gas water heater with PVC?
A standard will be needed for plastic flue pipes that should include a temperature gauge and a high limit probe. Then PVC, CPVC and polypropylene flue gas piping can be safely used on high efficiency boilers and water heaters. This would be an answer to the dilemma of cost versus safety.
What is code for venting a hot water heater?
The water heater must be vented in accordance with the section “Venting of Equipment” of the latest edition of the National Fuel Gas Code: ANSI Z223. 1/NFPA 54 in the United States and/or Section 7 of the CAN/CSA B149. 1 Natural Gas and Propane Installation Code in Canada, as well as applicable local building codes.
Does a water heater need a separate breaker?
Electric water heaters require a 240-volt dedicated circuit, which serves only the water heater and no other appliances or devices. The circuit wiring typically includes a 30-amp double-pole breaker and 10-2 non-metallic (NM) or MC cable.
How many amps does a gas furnace use?
Most gas heat furnaces use less than 600 watts of electricity, or less than half of a typical 15 amp electric circuit.
Does furnace circuit need to be GFCI?
If the furnace is not cord and plug connected and is direct-wired, then no GFCI protection is required, no matter where it is located. Yes, a GFCI is required.
Does a gas furnace require AFCI?
Yes, you need AFCI protection. As of the 2017 NEC, AFCI protection has been extended to all 15 and 20A, 120V branch circuit outlets in all dwelling unit locations. This includes dedicated appliances such as furnaces and dishwashers, and even smoke detector circuits.
Does a gas garage heater need a dedicated circuit?

Is there a difference between GFI and GFCI?
Ground fault circuit interrupters (GFCI) and ground fault interrupters (GFI) are the exact same device under slightly different names. Though GFCI is more commonly used than GFI, the terms are interchangeable.
How many outlets can 1 GFCI protect?
There’s no limit. A standard GFCI will protect up to 20 amps, drawn from any combination of receptacles, either the built-in one or any number of additional ones connected to its load terminals.
What requires AFCI breaker?
AFCI protection is currently required for all 15 and 20 amp branch circuits providing power to outlets* in residential family rooms, dining rooms, living rooms, parlors, libraries, dens, bedrooms, sunrooms, recreation rooms, closets, hallways, and similar rooms or areas.
When should you not use AFCI?
Exception: AFCI protection is not required for extension wiring that is less than 6 ft long (raceway or cable) if no outlets or devices are added (other than splicing devices). This measurement does not include the conductors inside an enclosure, cabinet, or junction box.
Should I replace breakers with AFCI?
The 2008 National Electrical Code (NEC) requires AFCI breakers in nearly all new construction. In 2017, the requirement was updated to require AFCI protection in virtually every room in a home.
