When installed indoors, the drafthood must be 

connected to a venting system. The venting system 

must be installed by a qualified installer and in 

accordance with the latest edition of ANSI Z223.1. In 

Canada, the installation must be in accordance with 

CAN1-B149.1 or .2, and any local codes that apply. 

The vent pipe must have a listed vent cap, and 

extend at least 2 feet (0.6 m) above any object within a 

10 foot (3.0 m) radius. 

NOTE: Do not use sheet metal screws at the 

snap lock joints of Type B double-wall gas vents.

Do not weld or bolt the vent pipe to the heater 

drafthood. The weight of the stack must not rest on the 

heater. The drafthood and heater top must be easily 

removable for normal heater service and inspection.

 

Avoid ending heater vents near air conditioning or 

air supply fans. The fans can pick up exhaust flue 

products from the heater and return them inside the 

building, creating a possible health hazard.

Avoid horizontal runs of the vent pipe and 90 

degree elbows, reductions, and restrictions. Horizontal 

runs should have at least a 1/4 inch (6.3 mm) rise per 

foot in the direction of flow. Support a vent connector 

for the design and weight of the material used to 

maintain clearances and physical damage and separate 

of joints.

Always use double-wall or insulated vent pipe 

(Type B or equivalent).

 

In cold weather, uninsulated outside vents can 

chill the rising flue products, blocking the natural 

draft action of the venting system. This can create 

a health hazard by spilling flue products into the 

heater room.

Avoid oversize vent piping or extremely long 

runs of the pipe which may cause too much cooling 

and condensation of flue gasses. 

When the installation of a power vent or draft 

fan in the venting system is necessary, qualified 

personnel should design the installation following 

good engineering practices and all applicable codes. 

A suitable draft switch must be wired into the heater 

control circuit at the terminal designated Field 

Interlock to keep the heater from firing unless there is 

a positive draft.

When a heater is removed from a common 

venting system, the venting system may be too large 

for proper venting of the other appliances connected 

to it.

If replacing an existing heater with a Copper 

Brute heater and the existing heater was connected 

to a common venting system, the common venting 

system must comply with ANSI Z223.1/National Fire 

Protection Association (NFPA) 54. When resizing any 

portion of the common venting system, the common 

venting system should be resized to approach the 

minimum size as determined using the tables in 

ANSI Z223.1/NFPA 54, Appendix G. In Canada, the 

common venting system should be resized so the  

installation will be in accordance with CAN/CGA 

B149.1 or .2.

Bradford White ships the heater with the 

water connections on the right side. The heater can 

be installed with the water connections on either 

side. It could be necessary, or helpful, to switch the 

connections to the left side to improve access for 

installation service. Have a professional service 

technician perform this modification before installing 

the heater using the following procedures: 
1.      Remove the front cover.
2.      If there is a vent cap or drafthood installed, they 

must be removed before removing the grate top 

assembly. On indoor installations (sizes 175-

250), the drafthood switch must be disconnected 

at the left side of the heater.

3.      If the unit is in the low-profile outdoor 

configuration, remove the hex-head screws 

(see Figure 15) and lift the grate top assembly 

straight up.

4.      Remove the screws that fastens the flue collector 

holddown clamps and remove the clamps (see 

Figure 16).

5.      Remove the flue collector assembly by lifting it 

out of the chassis.

6.      Remove the screws that fastens the gap closures 

and put them aside.

7.      Remove the three grommets.
8.      Remove the drain valves and plug. There is one 

hex plug on the left side, near the rear of the 

jacket. The drain valves are located on the left 

side and right side of the heater (see Figure 15).

9.      Remove the four screws that fastens the metal 

channels covering the capillary tube on the right 

side of the jacket, and lay the channels aside.
