6.
Insert both ends of the tubes into the headers. Insert the lower tube-end into the bottom
header first. Then insert the top tube-end into the top header. Insert all replacement tubes
before driving them.
7.
Drive the upper and lower tube-ends. DO NOT drive the tube-ends down to the flange. With
the driver tool positioned on the flange, strike the end of the driver with hammer. After a few
hits, the feel of the strike will become solid. The tone will also change from a “ting” sound to
more of a “tong” sound. This indicates the tube has seated.
CAUTION
Do Not Overdrive Tubes! Overdriving tubes can cause damage to the tubes and boiler
header holes. Use only approved Bryan Steam tube driver and specified hammer. The end-
formed tube fitting is designed to deform if overdriven to minimize damage to the vessel
tube holes.
8.
Reinstall the tube clamps. Replace the nuts and flat washers if damaged in any way. Use brass
nuts only! Tighten the nuts until snug. Do not try to compress the tube-ends into the holes with
the clamps, because the clamps might break or the stud might shear.
9.
Refill the boiler. Fill the unit with water and ensure that there is no leakage at the replacement
tube-ends before reinstalling the flue collector panels.
WARNING
If a leak is detected after a replacement tube has been installed, pressure in the boiler must
be reduced to zero before adjusting tube(s). Adjusting tubes under pressure could result in
serious personal injury.
10.
Reinstall all flue access doors, door clamps, and jacket panels.
11.
Perform startup check prior to putting boiler back into operation.
