_Onall boilers of two or more bases, the.,pilots.must.b.e„
connected by a tube header consisting of the following
size:
Propane gas - 1/4-inch tube for all sizes.
Natural gas - 1/4-inch tube up to boiler size 23;
3/8-inch tube on boiler sizes 23
through 33.
To assemble pilot header:
1. Install elbow to pilot tube on base opposite control
end.
2. Run pilot tube along manifold header connecting
each pilot to tube with a tee.
3. Continue this procedure to complete pilot header
