– No flammable materials within 3 feet
– Floor is level and capable of supporting full weight (approx. 150+ lbs empty, much more when full)
Use a level to check side-to-side and front-to-back alignment. Shim under the base if needed.
Maintain Clearance for Combustion
Gas models require proper combustion air:
– Two permanent openings (top and bottom) if in a confined space
– Minimum 1 sq. ft. free area per opening
– Follow manufacturer’s clearance to combustibles (typically 1 inch sides, 12 inches front)
Avoid placing near furnaces or clothes dryers unless properly vented.
Connect Water Supply Lines
Secure, leak-free water connections are essential for reliable operation.
Install Dielectric Unions or Nipples
To prevent corrosion between dissimilar metals:
– Install dielectric nipples on cold and hot water connections
– Wrap threads with Teflon tape (not on the first two threads to prevent tape shreds)
Hand-tighten first, then use a wrench for 1–2 additional turns.
Attach Flexible Connectors
Use flexible braided stainless steel connectors for easier alignment:
– Connect cold water inlet to the “Cold” label on the dip tube
– Hot outlet to the distribution line
– Avoid kinking or over-tightening
Open the cold water supply slowly after connections are secure.
Gas Line and Venting Setup (Gas Models)
For natural gas or propane Bradford White units, correct gas and venting installation is crucial.
Connect Gas Supply Line
Use a new gas connector or black iron pipe:
– Hand-thread first to avoid cross-threading

– Apply gas-rated pipe thread sealant (yellow tape or liquid sealant)
Never use standard Teflon tape on gas lines.
Test for Gas Leaks
After connection:
– Turn on gas supply
– Mix dish soap and water, then apply to all joints
– Look for bubbles indicating leaks
– If leaks appear, shut off gas and re-tighten or reseal
Never use a flame to test for leaks.
Install Proper Venting System
Bradford White gas water heaters require Category I venting:
– Use B-vent (double-wall metal pipe) for natural draft models
– Follow vertical rise requirements (typically 18–24 inches before any horizontal run)
– Terminate above roofline with a rain cap
Ensure all joints are sealed with high-temperature cement or foil tape.
Electrical Connections (Electric Models)
Electric Bradford White units demand correct wiring and circuit protection.
Verify Circuit Requirements
Most electric models require:
– 240-volt dedicated circuit
– Double-pole breaker (30–60 amps, depending on model)
– Correct wire gauge (typically 10/2 or 6/2 NM-B cable)
Ensure the electrical panel has capacity before proceeding.
Wire the Junction Box
Follow these steps:
– Strip cable ends and ground wire
– Connect black and red wires to brass terminals
– White wire (neutral) to silver terminal
– Ground wire to green screw
Seal the box with a waterproof conduit connector if in a damp location.
Test Power and Function
Turn on the breaker and check for:
– No tripped breakers
– Audible click from the thermostat
– Power indicator light (if equipped)
Wait 20–30 minutes before testing hot water to allow tank to fill and heat.
Final Safety and Performance Checks
Before declaring the installation complete, verify everything functions safely and efficiently.
