6.  Allow the heat exchanger to drain. Remove the 

front cover(s) by removing the rubber access 

strip(s) and the retaining screws. Remove the 
venting and remove the top, by removing the 

screws that attach the top to the side panels. 

Remove the side panels. Remove the front lower 

panels sealing the combustion area. To remove 
the gas train, disconnect the unions located 

below the intermediate pan and the field installed 
union located outside the cabinet, and pull up, 
bringing the union end connectors through the 

grommets in the intermediate pan. To remove the 
intermediate pan, remove the slide out control 

assembly and blower(s) to reveal the screws. 

Remove the screws holding the intermediate pan, 

and lift up to remove it. The heat exchanger has 
integral metal sections attached, which connect 

to the frame of the boiler. Locate and remove 
the screws along the front, rear and bottom of 
the integral metal sections, and remove the heat 

exchanger and metal sections by lifting up.On the 

larger appliances, a center heat exchanger support 

must be unbolted before it can be removed.

7.  Remove the heat exchanger from the unit.

NOTE: The heat exchangers are heavy and may 

require two people to remove to avoid personal injury.

8.  Clean the heat exchanger: A light accumulation 

of soot or corrosion on the outside of the heat 

exchanger can be easily removed. Use a wire 
brush to remove loose soot and scale from the 

heat exchanger. Do not use water or compressed 

air for cleaning.

9.  While the heat exchanger is out of the unit, 

inspect the firewall refractory insulation. Replace 

if necessary.

10.  Inspect the inside of the copper tubes for scale 

buildup. Scale can build up on the inner surface 

of the heat exchanger tubes, which can restrict 

water flow. If the tubes show signs of scaling, 

clean the internal surface. Bradford White offers 
a tube cleaning kit 

part number R0010000.

11.  Reassemble in the reverse order, and check 

appliance operation after start-up.
